  • Antimony: The Metal in Your Bullets, Your Furniture, and China’s Crosshairs

    On August 14, 2024, China’s Ministry of Commerce announced export controls on six categories of antimony-related products — ore, metals, oxide, and gold-antimony smelting and separation technologies — effective September 15. The stated reason was national security. The actual mechanism was the same one China had used on gallium and germanium the year before: require exporters to apply for dual-use export licenses through the Commerce Ministry, approve the licenses selectively, and let the uncertainty do the work. By December 3, China had escalated to a full ban on antimony exports to U.S. military end users. By July 2025, the price of antimony had hit $59,750 per metric ton — roughly a 4x increase from the $15,000-$18,000 range where it had traded through early 2024. A 55-metric-ton shipment of Australian-mined antimony concentrate, routed through a Chinese port on its way to a U.S. smelter in Mexico, was detained at the port of Ningbo for three months, then returned with broken seals and no explanation. The critical minerals supply chain had absorbed another hit, and most of the industries affected — flame retardants, ammunition, semiconductors, batteries, night vision systems — didn’t have a substitute.

    What antimony actually does

    Antimony is a metalloid — a silvery-white element that sits between metals and nonmetals on the periodic table — and its defining industrial property is that it makes other things harder, more fire-resistant, and more durable. About half of all antimony consumed globally goes into flame retardants, primarily as antimony trioxide, which is mixed into plastics, textiles, cables, and coatings to prevent or slow combustion. Every upholstered piece of furniture that meets fire safety codes, every cable sheath in a data center, every circuit board housing in consumer electronics — antimony trioxide is in the compound that keeps it from catching fire. The other half splits across applications that are individually smaller but collectively indispensable: hardening lead in ammunition and lead-acid batteries, semiconductor compounds, infrared sensors, precision optics, nuclear reactor control rods, and ceramic glazes.

    The defense applications are what pushed antimony onto the U.S. Department of Interior’s critical minerals list and what makes the Chinese export controls a national security issue rather than just a commodity market disruption. Antimony hardens the lead in bullets — without it, projectiles deform on impact and lose penetrating capability. It’s a component in armor-piercing ammunition, night vision goggles, infrared missile seekers, and military battery systems. The U.S. consumed roughly 22,000 tons of antimony in 2023. China supplied 63% of U.S. imports. The next largest supplier was Belgium, at 8%. The U.S. has not had a domestic antimony mine in production since the early 2000s. The last significant domestic reserve — the Stibnite mine in central Idaho, now owned by Perpetua Resources — has received Department of Defense funding but isn’t expected to begin production until 2028 at the earliest, and even then its antimony grades average less than 0.5%, which is roughly 50 times lower than the 25% concentrate minimum that roasters need to produce metal and antimony trioxide efficiently. The CHIPS Act’s critical minerals provisions addressed some of these vulnerabilities at the legislative level. The operational reality is that legislation and mine output operate on fundamentally different timescales.

    The price chart tells the story

    Antimony’s price action in 2024-2025 is one of the most dramatic commodity charts of the decade. Through early 2024, the metal traded between $15,000 and $18,000 per metric ton — already elevated from historical levels due to supply tightness, but within a range that existing procurement budgets could absorb. Between the August announcement and September implementation of the export controls, prices doubled. By the end of 2024, they had tripled. By mid-2025, European antimony prices exceeded $60,000 per metric ton — a roughly 4x increase in under a year. This wasn’t speculative froth. The largest antimony roaster outside of China — an Omani facility that had been supplying much of the Western world’s antimony trioxide and ingots, processing roughly 20,000 metric tons of contained antimony annually — went bankrupt during the same period, unable to secure sufficient raw material at prices its contracts could support. The supply chain lost its single largest non-Chinese processing node at the exact moment it needed it most.

    The price spike created a two-tier market that mirrors what happened with gallium and germanium — domestic Chinese prices stabilized and even pulled back as export restrictions reduced outbound volume, while international prices soared. Chinese consumers of antimony — manufacturers of flame retardants, batteries, semiconductors, ammunition — gained a cost advantage over their Western competitors. Whether that cost advantage was an intended consequence of the export controls or a side effect is, at this point, a distinction without a meaningful difference. The structural pattern is the same one China has deployed across rare earths, gallium, germanium, graphite, and tungsten: control enough of the global supply chain that export licensing decisions function as de facto trade policy, without the formal trade-war optics of tariffs or quotas.

    Why there’s no quick fix

    The antimony supply chain has three structural characteristics that make diversification harder than the “just find another supplier” framing suggests.

    The first is geology. Antimony deposits are geographically concentrated. China produces 48% of global output. Russia and Tajikistan are the next largest producers — neither of which solves the geopolitical dependency problem for Western buyers. Bolivia, Turkey, and Myanmar produce smaller volumes. Australia has deposits but limited processing capacity. The global production base outside of China and its strategic allies is genuinely thin, and the thin parts are years away from meaningful expansion.

    The second is processing. China controls not just mining but an estimated 74% of global antimony trioxide refining capacity. Even if a Western mining company could produce antimony concentrate tomorrow, it would need a roaster to convert that concentrate into the oxide or metal that downstream manufacturers actually use. The Omani roaster’s bankruptcy removed the largest non-Chinese processing facility from the global supply chain. Building new roasting and refining capacity is a multi-year, capital-intensive process with environmental permitting requirements that vary by jurisdiction and add time in every one of them.

    The third is substitution — or the lack of it. For most of antimony’s critical applications, there is no drop-in substitute. Antimony trioxide’s combination of flame-retardant effectiveness, compatibility with a wide range of polymers, and cost has made it the industry standard for decades. Alternative flame retardants exist — aluminum trihydrate, magnesium hydroxide, ammonium polyphosphate — but they require reformulation of the polymer systems they’re added to, requalification testing, and in many cases higher loading levels that change the physical properties of the end product. For ammunition hardening, antimony has no practical substitute at scale. The Department of Defense has recognized this explicitly. The constraint isn’t that alternatives don’t exist in a laboratory. The constraint is that switching materials in industrial and military supply chains is a process measured in years, not months — and the export controls created an immediate shortage, not a multi-year one.

    The defense industrial base problem

    The antimony shortage intersects with a broader constraint that our Battlefields of the Future course covers in detail: the Western defense industrial base is not built for sustained high-intensity conflict. U.S. foreign military sales reached a record $238 billion in 2023, driven by demand from the wars in Ukraine and the Middle East. Ammunition consumption in Ukraine alone has exceeded production rates across NATO countries for most of the conflict. The loitering munitions and drone warfare revolution has changed the calculus of what modern armies need — but conventional ammunition remains the backbone of ground combat, and conventional ammunition requires antimony.

    The irony is structural: the country that supplies the ammunition-hardening material to Western militaries is the same country whose military modernization program — conducted through entities like the China Poly Group and the broader military-civil fusion strategy — those Western militaries are arming against. China controls the supply chain for a material that Western armies need to fight, and has the ability to restrict that supply chain at will. The export controls on antimony are, in that framing, not a trade dispute. They are a capability constraint imposed by a strategic competitor on its adversaries’ defense industrial base, using the commodity market as the delivery mechanism.

    What’s happening now

    By early 2026, the panic-driven shortage of 2025 has partially eased. Southeast Asian processing capacity has begun coming online. Chinese export license approvals have become more predictable, though still selective. Prices have retreated from the July 2025 peak but remain well above pre-2024 levels — the structural fragmentation Beijing created isn’t reversible through market forces alone. Companies that diversified sourcing in 2025 are paying premiums for supply security. Companies that didn’t are still exposed.

    Perpetua Resources’ Stibnite mine in Idaho remains the highest-profile domestic alternative, with DOD investment and a projected capacity that could supply up to 35% of U.S. antimony demand. Production isn’t expected until 2028. The timeline has slipped multiple times. Turkish mines are producing at 1-2% feed grades, struggling to concentrate their output to the 25% minimum that roasters require. The gap between what the Western world needs — reliable, non-Chinese antimony supply at industrial scale — and what the Western world has built is measured in years of mine development, roaster construction, and permitting that hasn’t started yet. The rare earth recycling infrastructure that would eventually allow antimony recovery from end-of-life batteries and flame retardant products is even further behind — the U.S. currently recovers about 18% of its antimony demand through lead-acid battery recycling, which is one of the few bright spots in an otherwise thin domestic supply picture.

    Why it matters beyond antimony

    Antimony is Lecture 32 of 36 in the Rare Earth Elements course, and by the time you get to it, the pattern is unmistakable. Gallium and germanium: export controls in 2023. Graphite: export controls in 2023. Rare earth processing technologies: export ban in December 2023. Antimony: export controls in August 2024, escalated to a military-end-user ban in December 2024. Tungsten and superabrasives: export controls in early 2025. Each announcement follows the same mechanism — license requirements, selective approvals, price spikes, two-tier markets, downstream industry disruption — and each one reveals the same underlying structural vulnerability: China’s dominance of critical mineral supply chains is not limited to mining. It extends through refining, processing, and manufacturing, at concentrations that give Beijing the ability to impose costs on adversaries through commodity markets rather than military force.

    The semiconductor supply chain has its own version of this vulnerability — concentrated in a different geography, dependent on a different set of materials, but structurally identical in the sense that a small number of facilities and a small number of countries control chokepoints that the global economy cannot easily route around. The antimony case is smaller in dollar terms than semiconductors or rare earth magnets. But the pattern it demonstrates — that a $15,000-per-ton metalloid can become a $60,000-per-ton national security crisis in eight months because one country controls both the mine output and the refining capacity — is the pattern that defines the critical minerals landscape of the 2020s.

    This is the kind of supply chain vulnerability our Rare Earth Elements course was built to map — where a metal most people have never heard of turns out to be the reason their furniture doesn’t catch fire, their bullets work, and their night vision functions, and the country that supplies 48% of it just decided that continued supply is conditional.

  • Critical Minerals and the CHIPS Act: How the US Is Trying to Build a Domestic Supply Chain

    The CHIPS and Science Act was signed into law in August 2022 to rebuild American semiconductor manufacturing. By 2025, the Trump administration had redirected at least $2 billion of its funding toward something the original legislation barely mentioned: critical minerals. The pivot tells you everything you need to know about where the actual bottleneck sits. You can build a semiconductor fab in Arizona — and the U.S. is building several — but if the neodymium magnets in the fab’s equipment, the gallium in the compound semiconductors, the germanium in the fiber optics, the cobalt in the tooling alloys, and the rare earth elements in the electric motors all come from China, then you’ve built a factory that runs on your adversary’s supply chain. The CHIPS Act started as a semiconductor bill. It’s becoming a critical minerals bill because the people implementing it realized the two problems are the same problem.

    The scale of the dependency

    China controls approximately 90 percent of global rare earth processing, 80 percent of gallium production, 98 percent of gallium metal output, 60 percent of germanium, and dominant shares of graphite, manganese, and cobalt refining. The United States has exactly one operational rare earth mine — MP Materials’ Mountain Pass facility in California — and until recently had zero domestic capacity to separate rare earth oxides into individual elements, zero capacity to produce rare earth metals from those oxides, and zero capacity to manufacture the neodymium-iron-boron permanent magnets that go into everything from F-35 fighter jets to MRI machines to wind turbine generators to EV motors. The U.S. mined the ore and shipped it to China for processing. That’s like growing wheat and sending it abroad to be turned into bread.

    When China imposed export controls on gallium and germanium in July 2023, exports dropped 97 percent in three months. European prices doubled. The demonstration was unambiguous: China could turn the valve on materials that the defense industrial base requires and the U.S. has no domestic alternative for. The semiconductor supply chain runs through a handful of chokepoints. The critical minerals supply chain runs through fewer. And unlike chips, where TSMC’s advantage is technological, China’s advantage in minerals processing is infrastructural — built over three decades of sustained investment that the U.S. chose not to match.

    What the government is actually doing

    The response since 2025 has been the most aggressive federal intervention in mining and materials processing since the Strategic Petroleum Reserve was established. The Department of Defense’s Office of Strategic Capital deployed over $4.5 billion in capital commitments by January 2026, closing six major critical mineral deals in a single year. The scale and structure of individual deals illustrate how far the government is willing to go.

    MP Materials — the Mountain Pass operator and sole U.S. rare earth miner — received a $400 million equity investment from the Pentagon plus a $150 million loan to build heavy rare earth separation capacity in California. The Pentagon also established a price floor of $110 per kilogram for neodymium-praseodymium oxide — effectively guaranteeing MP Materials a minimum revenue regardless of market fluctuations. That’s the government acting as both investor and customer, de-risking a market that private capital alone won’t enter because Chinese producers can dump prices below any Western competitor’s cost of production.

    Vulcan Elements and ReElement Technologies secured a $1.4 billion public-private partnership — $620 million in Pentagon loans, $50 million from the Department of Commerce under the CHIPS Act (with the government receiving an equivalent equity stake), and $550 million in private capital — to manufacture up to 10,000 metric tons of NdFeB magnet material domestically. USA Rare Earth announced a $1.6 billion debt and equity package with the government taking a 10 percent ownership stake. In Alaska, the Pentagon invested $35.6 million for a 10 percent stake in Trilogy Metals’ Upper Kobuk project. In Louisiana, Ucore Rare Metals received $18.4 million from the Army for a commercial-scale rare earth separation facility.

    The National Defense Stockpile, a strategic reserve created in 1939 and largely neglected for decades, received $2 billion in new funding through the One Big Beautiful Act. The Pentagon announced intent to procure up to $1 billion in stockpile materials, issuing requests for information on scandium, tungsten, graphite, samarium, dysprosium, and terbium — minerals for which the U.S. has known deposits but essentially zero commercial production capacity.

    The permitting acceleration is the other half. A March 2025 executive order expanded Defense Production Act authorities, reduced approval requirements, and directed streamlined permitting for mineral projects. The Department of the Interior published a new Critical Minerals List in November 2025, expanded from 50 to include additional materials based on updated methodology. In January 2026, Section 232 tariff actions targeted processed critical minerals alongside semiconductors — not yet imposing duties on minerals, but establishing monitoring frameworks and requiring Commerce to report on whether future restrictions are warranted.

    Why it might not work fast enough

    The money is real. The policy intent is clear. The problem is time. The average timeline from mineral discovery to production in the United States is 17 to 29 years. Environmental review, permitting, judicial challenge, construction, commissioning, and ramp-up each take years. China didn’t build its mineral processing dominance through a single piece of legislation. It built it through three decades of sustained investment, deliberately subsidized production, environmental shortcuts that no Western democracy would permit, and strategic acquisition of mining assets worldwide — an estimated $57 billion invested in copper, cobalt, nickel, lithium, and rare earth mines and processing facilities from 2000 to 2021.

    The CHIPS Act-funded investments will take years to produce operational output. Vulcan Elements’ 10,000-ton magnet facility hasn’t been built yet. MP Materials’ heavy rare earth separation capacity is under development. The Thacker Pass lithium project in Nevada — the largest lithium deposit in the U.S. — had its Department of Energy loan restructured in October 2025 to include debt service deferrals, which tells you the economics remain fragile. The Pentagon’s price floor mechanism for rare earths is an admission that the market alone won’t sustain domestic production against Chinese competitors who operate at lower cost, lower environmental standards, and with direct state subsidy.

    There’s also a geographic diversification play that acknowledges the U.S. can’t do everything domestically. MP Materials announced a joint venture with the Pentagon and Saudi Arabia’s Ma’aden to build a rare earth refinery in Saudi Arabia — expanding non-Chinese separation capacity outside U.S. borders but within allied supply chains. The Export-Import Bank’s Supply Chain Resiliency Initiative finances upstream projects in allied countries where U.S. manufacturers have signed offtake agreements. The strategy is “friend-shoring” — building mineral processing capacity in countries that won’t weaponize it against the U.S. — because building it all domestically would take longer than the threat allows.

    The honest assessment

    The U.S. went from zero critical mineral strategy to $4.5 billion in deployed capital in roughly 18 months. That’s fast by government standards. It’s not fast by supply chain standards. China’s rare earth monopoly wasn’t built in 18 months, and it won’t be unwound in 18 months. The investments are necessary. They are not sufficient. And the fundamental constraint — that opening a mine in the U.S. takes longer than a presidential term — means the strategy requires continuity across administrations, which is the one thing American mineral policy has never had.

    The CHIPS Act’s evolution from semiconductor legislation to critical mineral funding vehicle is the clearest illustration of a lesson the copper shortage, the helium crisis, and the gallium export controls all teach independently: the energy transition, the AI buildout, and the defense industrial base all depend on the same materials, sourced from the same places, processed through the same chokepoints. We cover the full critical minerals landscape — from neodymium magnet manufacturing to China’s processing monopoly to the CHIPS Act response — across our Rare Earth Elements course, where the question isn’t whether the U.S. has the money to build a domestic supply chain but whether it has the time.

  • Uranium Supply Chain 2026: Nuclear Renaissance Meets Mining Reality

    The United States operates 93 nuclear reactors — the largest fleet on earth — and cannot fuel a single one with domestically sourced uranium. The country has essentially no primary uranium production. The mines that once operated in Wyoming, Texas, and the Colorado Plateau shut down decades ago when prices collapsed, and the supply chain that supported them — the skilled labor, the processing infrastructure, the regulatory pipelines — dissolved with them. In 2026, spot uranium is approaching $92 per pound. Analysts project prices reaching $100 to $120 per pound, with some upside scenarios targeting $135 if supply fails to respond. The U.S. government has committed up to $80 billion to build new reactors and reinvigorate the nuclear industrial base. The USGS added uranium to its 2025 Critical Minerals List for the first time in years. The IEA forecasts annual nuclear investment rising from over $70 billion today to approximately $210 billion by the mid-2030s. Roughly 65 reactors are under construction worldwide.

    The demand story is real. The supply story is the problem.

    Where the uranium comes from

    Global reactor demand runs approximately 67,500 metric tons of uranium per year. Mine production has historically met only 74 to 90 percent of that, with the deficit covered by drawdowns from government and commercial inventories, recycled material, and secondary supply. Those secondary sources are depleting. The market is transitioning from an inventory-driven system to a production-driven one, and production isn’t keeping up.

    Kazakhstan dominates. Kazatomprom, the state-owned producer, is the world’s largest uranium miner, operating primarily through in-situ recovery — a technique that pumps acidified solution into uranium-bearing rock formations underground and extracts the dissolved uranium without conventional mining. Kazakhstan accounts for roughly 40 percent of global production. Canada’s Cameco operates McArthur River and Cigar Lake in Saskatchewan’s Athabasca Basin — two of the highest-grade uranium deposits on earth, with licensed capacity of 25 million pounds annually and proven reserves exceeding 457 million pounds. Australia, Namibia, Uzbekistan, and Niger round out the major producers. Russia controls a significant share of global uranium enrichment and conversion — the processing steps between mining raw uranium and fabricating reactor fuel.

    The concentration is the vulnerability. A large proportion of uranium production sits in non-Western jurisdictions. Sanctions, export bans, and the war in Ukraine are constraining the nuclear fuel cycle. Niger — historically a significant supplier — produced no uranium at all in 2025 after a military junta seized power and disrupted operations at the SOMAÏR facility. Kazakhstan has announced lower production targets for 2026. McArthur River reduced its 2025 output due to development delays. In the United States, several in-situ recovery restarts have ramped up more slowly than planned. The net effect: tighter global supply for reliable primary production, at precisely the moment when demand forecasts keep getting revised upward.

    The demand surge

    Three forces are converging on uranium demand simultaneously.

    The first is reactor life extensions and restarts. Existing nuclear plants that were scheduled for retirement are getting new operating licenses instead. Plants that were shut down are being evaluated for restart. The economics shifted when natural gas prices spiked, renewable intermittency proved harder to manage than projected, and carbon-free baseload generation became a policy priority rather than a political liability. Nuclear went from a technology that governments were phasing out to one they’re subsidizing.

    The second is new reactor construction. The $80 billion U.S. government commitment includes Westinghouse AP1000 deployments and GE Hitachi BWRX-300 small modular reactors. Canada has broken ground on SMRs at the Darlington nuclear station with combined funding commitments of roughly CAD 3 billion and a target completion around 2030. The U.S. and Japan announced a framework totaling $550 billion, with up to $332 billion directed to energy and AI-linked infrastructure including new nuclear capacity. China continues building reactors at a pace no other country matches and purchasing uranium in large quantities to stockpile for its future fleet.

    The third is AI data centers. This is the demand driver that didn’t exist in anyone’s forecast five years ago. Hyperscale computing facilities require baseload power — reliable, 24/7 generation that doesn’t depend on weather or time of day. Nuclear fits that requirement better than any other carbon-free source. More than 63 percent of investors surveyed by Uranium.io believe AI-related electricity consumption will become a material factor in nuclear planning over the next decade. Microsoft, Amazon, and Google have all explored or announced nuclear power agreements for data center operations. The AI demand signal is being treated as structural rather than cyclical — permanent new load on the grid that requires permanent new generation.

    Why supply can’t respond quickly

    This is the constraint that the nuclear renaissance runs into. Uranium mining is not a faucet. Mine restarts require years, not months. The lead time from decision to production involves permitting (often multi-year regulatory processes), environmental review, workforce recruitment (specialized uranium mining labor that largely doesn’t exist anymore in the West), facility construction or refurbishment, and ramp-up testing. A mine that was shuttered in 2012 can’t resume production in 2026 just because the price is right.

    Beyond mining, the fuel cycle has its own bottlenecks. Mined uranium (yellowcake) must be converted to uranium hexafluoride, enriched to increase the concentration of fissile U-235, fabricated into fuel assemblies, and delivered to the reactor. Russia controls a significant share of global enrichment and conversion capacity. The U.S. ban on Russian uranium imports — signed into law in 2024 — created a scramble for alternative enrichment services. Centrus Energy is the only licensed producer of High-Assay Low-Enriched Uranium (HALEU) in the Western world — the next-generation fuel that advanced reactors and many SMR designs require. Centrus is expanding its Piketon, Ohio facility, but scaling enrichment infrastructure is measured in years and billions of dollars, not quarters.

    The structural reality: even sustained high prices may not resolve supply deficits within typical investment horizons. Producers have signaled that three-digit prices per pound — above $100 — are the minimum necessary to incentivize new mine development at a scale that reflects actual capital costs, permitting timelines, and supply chain risk. The market is in a standoff. Utilities want to buy at current prices. Producers want higher prices before committing capital to new production. China, meanwhile, continues buying at whatever price the market offers, building strategic reserves while Western utilities defer purchases and hope prices stabilize.

    The SMR fuel problem

    Small modular reactors are the technology that’s supposed to make nuclear faster, cheaper, and more deployable. The first SMRs won’t be operational until 2030 or 2031. The World Nuclear Association projects SMR capacity could account for roughly 7 percent of global nuclear power generation by 2040. But many advanced SMR designs require HALEU — uranium enriched to between 5 and 20 percent U-235, compared to the 3 to 5 percent used in conventional reactors. HALEU production capacity in the Western world is essentially nonexistent outside of Centrus’s pilot-scale operations. Russia was the primary commercial supplier of HALEU before sanctions disrupted the trade.

    Building the SMR fleet without the fuel to power it is the kind of sequencing error that turns a technology roadmap into a bottleneck cascade. The reactors require enrichment capacity that requires enrichment facilities that require regulatory approval that requires years. Cameco’s $2.8 billion ten-year supply agreement with India and Centrus’s $1.2 billion in convertible note offerings and $2 billion in contingent utility purchase commitments represent the financial architecture being constructed to close these gaps. Whether the construction finishes before the demand arrives is the open question.

    The investment case and the honesty test

    Uranium is one of the few commodities where there is essentially no substitution potential. A nuclear reactor runs on uranium. Nothing else does the job. Demand is inelastic — utilities will pay whatever the market requires because the cost of uranium is roughly 5 to 7 percent of a reactor’s total operating budget. A doubling of uranium prices is a rounding error in the cost of nuclear electricity. This means utilities will eventually buy at higher prices because they have no alternative. The question is when, not whether.

    Long-term contract prices have risen to $86 per pound, indicating that utilities are accepting elevated costs even as they resist spot purchases. The World Nuclear Association has revised its uranium demand growth forecast to a 5.3 percent compound annual growth rate through 2040, up from 4.1 percent previously. Analysts project a supply deficit building over the next decade as mine production continues to lag reactor requirements. More than 85 percent of surveyed investors anticipate higher prices into 2026.

    The honesty test: every part of this demand story — reactor restarts, new construction, SMRs, AI data centers — requires uranium, and the supply chain to deliver it doesn’t exist at the scale the demand forecasts imply. The nuclear fuel supply chain is being rebuilt in real time, by governments writing checks and producers scaling operations, against a backdrop of geopolitical disruption, depleted inventories, and a workforce that needs to be reconstituted essentially from scratch in the West. The nuclear renaissance is real. The mining and enrichment infrastructure to fuel it is years behind.

    We cover the uranium supply chain alongside gallium and germanium export controls, the helium shortage, and the full landscape of critical materials that modern technology and energy systems depend on across our Rare Earth Elements course — including why the largest nuclear fleet on earth can’t fuel itself, and what that means for a planet betting on reactors to keep the lights on.

  • Gallium and Germanium: China’s Newest Export Control Weapons and Why Chips Need Them

    In July 2023, China’s Ministry of Commerce announced export controls on gallium and germanium—two metals most people have never heard of, both of which are essential to semiconductor manufacturing, fiber optics, infrared optics, solar cells, and military hardware. Exporters were required to apply for licenses, disclose end-use information, and identify the final destination of every shipment. The result was immediate: Chinese gallium exports dropped from 6,876 kilograms in July 2023 to 227 kilograms in October 2023. Germanium fell from 7,965 kilograms to 590 kilograms in the same period. European prices for both metals nearly doubled within a year. By May 2025, the Rotterdam price of gallium had hit $687 per kilogram—an increase of over 150 percent from pre-control levels. Meanwhile, gallium prices inside China fell, because domestic oversupply had nowhere to go. Beijing was sitting on cheap material it refused to sell, watching the rest of the world scramble.

    In December 2024, China escalated to an outright ban on gallium and germanium exports to the United States, along with antimony and superhard materials—a direct retaliation for the Biden administration adding 140 Chinese semiconductor companies to the Entity List. The ban was suspended in November 2025 as part of bilateral trade negotiations, with general licenses issued through November 2026. But the legal framework remains intact. The controls can be reactivated at any time. The message was delivered: China controls 98 percent of global gallium production and 60 percent of germanium, and it’s willing to use that leverage the same way OPEC uses oil—as a strategic instrument with a valve.

    What gallium and germanium actually do

    These aren’t rare earth elements—they’re critical minerals with their own supply chain vulnerabilities and their own reasons for mattering.

    Gallium’s primary semiconductor application is gallium nitride (GaN), a wide-bandgap material that handles higher voltages, operates at higher temperatures, and switches faster than silicon. GaN-based chips are more efficient and more durable than their silicon equivalents, which is why they’re displacing silicon in power electronics, fast chargers, 5G base stations, radar systems, and military communications hardware. Gallium arsenide (GaAs) is the backbone of radio-frequency chips in smartphones—the components that connect your phone to a cell tower use gallium, not silicon. Every 5G phone on earth contains gallium-based semiconductors. LED lighting runs on gallium compounds. The photovoltaic industry uses gallium in high-efficiency multijunction solar cells for spacecraft and concentrated solar installations.

    Germanium’s niche is narrower but equally non-substitutable. Its high electron mobility makes it essential for high-speed transistors. It’s the material of choice for infrared optical components—night vision goggles, thermal imaging cameras, missile guidance systems, satellite sensors. Fiber-optic cables use germanium-doped silica to minimize signal loss over long distances, which means the physical infrastructure of the internet—the glass cables that carry data between continents—depends on a material that one country dominates. An F-35 fighter jet’s infrared targeting system, the fiber-optic backbone connecting data centers, and the night vision goggles worn by infantry all share a supply chain vulnerability that runs through Beijing.

    How China got here

    Gallium doesn’t occur in nature as a primary ore. It’s a byproduct of aluminum smelting—extracted from bauxite processing residues at concentrations so low that recovery is only economical if you’re already running an aluminum smelter at scale. China produces more aluminum than any other country on earth, which means it generates more gallium-bearing waste streams, which means it dominates gallium production not because it set out to corner the market but because it cornered the upstream industry that gallium falls out of. The same pattern: whoever processes the most bauxite gets the most gallium, and China processes the most bauxite.

    Germanium is slightly more distributed—China controls 60 percent rather than 98 percent—but the refining infrastructure is similarly concentrated. Global annual demand for gallium is below 700 metric tons, a fraction of markets like copper (25.9 million tons) or nickel (3.1 million tons). The small market size is itself a strategic advantage for Beijing: it’s easier to manipulate a 700-ton market than a 25-million-ton market. Small disruptions in supply produce large price swings, which gives China leverage that’s disproportionate to the tonnage involved.

    The controls weren’t random. They were calibrated responses to specific American actions. The August 2023 licensing requirement answered the initial rounds of U.S. chip export controls. The December 2024 ban answered the Entity List expansion. The November 2025 suspension was part of a broader negotiated pause. Each escalation was timed, proportional, and reversible—designed to demonstrate capability without triggering a full decoupling. China has been explicit that the controls are not permanent policy. They’re a deterrent. The message: if you restrict our access to advanced chips and lithography equipment, we restrict your access to the materials those chips are made from.

    The rerouting problem

    The ban is leakier than it looks. Stimson Center analysis of Chinese customs data found that in 2024, the quantity of germanium exported to the United States fell by approximately 5,900 kilograms—almost exactly the amount by which germanium exports to Belgium increased (6,150 kilograms). The combined total to both countries was essentially flat across 2023 and 2024. The material appears to be flowing through third-country intermediaries that reimport it to the United States without Chinese end-use restrictions applying.

    For gallium, the picture is more complicated because Canada and Germany have secondary gallium production from their own aluminum smelting operations, making it harder to distinguish genuine non-Chinese supply from rerouted Chinese material. The U.S. Census Bureau records imports by the country that produced the material unless it underwent “substantial transformation” in a third country—a classification that creates ambiguity about whether Belgian-processed germanium originally sourced from China counts as Belgian germanium.

    The rerouting doesn’t eliminate the vulnerability. It adds cost, uncertainty, and transit time. It creates a supply chain that depends on Beijing’s tolerance of the workaround, which can be withdrawn. And it doesn’t address the fundamental concentration: if China decided to enforce end-use controls across all destinations—not just the United States—the third-country channels would close.

    What the West is building

    The response has been faster than for rare earths but still measured in years rather than months.

    MTM Critical Metals is building a facility in Texas to extract gallium from industrial scrap, scheduled to begin operations in early 2026—an unusually fast timeline for critical mineral projects. The company is reportedly negotiating binding agreements with Indium Corporation that include minimum price floors designed specifically to protect against Chinese market manipulation. Canada’s 5N Plus and Germany’s PPM Pure Metals have secondary production from domestic aluminum operations. Japan has invested in recycling infrastructure to reduce import dependence.

    The EU’s Critical Raw Materials Act targets reducing dependency on single-source suppliers. The CHIPS Act allocated funding for domestic semiconductor material infrastructure. But the structural problem is the same one that affects rare earth diversification: building new supply takes years, the markets are small enough that Chinese pricing can undercut new entrants at will, and the byproduct economics mean you can’t produce gallium at scale without producing aluminum at scale, which means diversifying gallium supply requires diversifying an entire upstream industry.

    Gallium prices inside China are lower than international prices because the domestic surplus can’t be exported. If China eventually lifts all controls, the price crash could make every Western diversification project uneconomic overnight—the same dynamic that has killed rare earth mining ventures outside China for two decades. Beijing doesn’t need to maintain the export ban permanently. It just needs the threat of reimposing it, combined with the ability to flood the market with cheap material if Western alternatives get too close to viability. The weapon isn’t the embargo. It’s the optionality.

    What it tells you about the next decade

    Gallium and germanium are test cases for a broader pattern. China identified that its dominance of bauxite processing gave it accidental control of a small but critical material, weaponized that control in response to American technology restrictions, calibrated the escalation to demonstrate capability without provoking full decoupling, and then suspended the controls as a negotiating chip—while keeping the legal framework active for reimposition. Every element in the critical minerals portfolio—antimony, graphite, rare earth processing technology, medium and heavy rare earths—has been subject to the same playbook in sequence since 2023.

    The progression: rare earth processing dominance (established over decades) → gallium and germanium controls (2023) → antimony controls (2024) → rare earth processing equipment and technology controls (October 2025, suspended November 2025). Each step expands the scope. Each suspension is temporary and conditional. The architecture for comprehensive export controls across the entire critical minerals supply chain is built. It’s just not fully activated—yet.

    We cover gallium and germanium alongside the helium shortage, rare earth recycling, and the full landscape of critical materials that underpin modern technology across our Rare Earth Elements course—including why the most strategically important metals in the semiconductor supply chain are ones most people can’t name, produced as byproducts of industries most people don’t think about, and controlled by a country that knows exactly what it has.

  • The Global Helium Shortage: Why a Party Balloon Gas Is a National Security Concern

    In March 2026, Iran struck Qatar’s largest liquefied natural gas facility. The damage knocked helium production lines offline—lines that could take years to rebuild. Qatar produces roughly one-third of the world’s helium supply, approximately 63 million cubic meters out of a global total of 190 million in 2025. That output is now functionally zero. About 200 specialized containers used to transport liquid helium are stranded near the Strait of Hormuz. The World Economic Forum estimates that conflict-related disruptions have removed approximately one-third of the global helium supply from the market. Spot prices have doubled since the war began. QatarEnergy issued a force majeure declaration on March 4, 2026, triggering cascading contractual mechanisms across every industry that depends on a gas most people associate with birthday balloons.

    Helium is not a rare earth element. It’s the second most abundant element in the universe. It is, however, vanishingly scarce on Earth in usable concentrations, impossible to synthesize economically, and—unlike every other industrial gas—cannot be recaptured once it escapes into the atmosphere. It floats up and is gone. Every cubic meter of helium vented, leaked, or released from a party balloon is helium that the planet’s industrial base will never use again. The global economy runs on a nonrenewable gas with no substitute for its most critical applications, produced as a byproduct of natural gas processing in a handful of countries, and one-third of that supply just went offline because of a conflict that has nothing to do with helium.

    What helium actually does

    The party balloon market accounts for a negligible fraction of global helium consumption. The applications that matter are the ones where no alternative exists.

    MRI machines require approximately 1,500 to 2,000 liters of liquid helium to cool their superconducting magnets to operating temperature—near absolute zero. There are roughly 40,000 to 50,000 MRI scanners installed worldwide, each requiring refills every two to six weeks. Healthcare accounts for roughly 32 percent of global helium consumption. When helium runs short, hospitals delay installations of new MRI systems, and existing systems face refill scheduling constraints. Each nonfunctional MRI scanner eliminates approximately 20 to 30 daily patient examinations.

    Semiconductor manufacturing accounts for 24 percent of global consumption in 2025, projected to reach 30 percent by 2030. Helium cools superconducting magnets during chip fabrication, flushes toxic residue after wafer washing, and supports leak detection in the vacuum systems that advanced lithography depends on. EUV lithography—the technology that makes sub-5-nanometer chips possible—has driven semiconductor helium demand from roughly 6 percent of global consumption in 2015 to 10 to 12 percent by 2025. With TSMC, Samsung, and Intel all building new fabs under the CHIPS Act and equivalent programs worldwide, and 42 new fabrication facilities scheduled to come online by 2026, semiconductor demand for helium is growing 15 to 20 percent annually. In 2024, Samsung’s Vietnam fabrication plant experienced a 72-hour outage from helium supply disruption, resulting in approximately $300 million in losses.

    Aerospace consumes 18 percent of global demand. NASA’s Artemis program alone requires 3.2 million cubic feet per Space Launch System launch. Quantum computing requires helium-cooled cryogenic systems to maintain qubits at millikelvin temperatures. The International Energy Agency has warned that helium shortages could delay quantum computing adoption by two to three years. Defense applications—missile guidance systems, surveillance technologies, and components manufactured using helium-dependent processes—consume classified but significant volumes.

    The CHIPS Act allocated approximately $2.1 billion specifically for helium infrastructure to support domestic semiconductor production. The Department of Defense has established a target of maintaining a six-month helium reserve by 2026, up from the 83-day reserve that existed before the current crisis. Twenty-two countries now require special licenses for helium exports, citing national security concerns.

    Why supply is this fragile

    Helium is produced almost entirely as a byproduct of natural gas processing. You don’t mine helium. You extract it from natural gas fields where it occurs in concentrations of 0.1 to 7 percent, separated during cryogenic processing of the primary product—LNG. This byproduct structure creates a fundamental vulnerability: helium production depends entirely on natural gas production decisions. When QatarEnergy halted LNG operations, helium supply ceased automatically—not because the helium market changed, but because the primary revenue driver went offline.

    Three countries dominate supply. The United States has historically been the largest producer, anchored by the Federal Helium Reserve in Amarillo, Texas—a strategic stockpile that the U.S. government began building in the 1920s for military airships. Congress passed the Helium Privatization Act in 1996, directing the Bureau of Land Management to sell off the reserve and wind down government involvement in helium markets. That logic—reducing government involvement in commodity markets—made sense when helium’s primary applications were party balloons and weather balloons. It looks catastrophically shortsighted in 2026, when helium is a strategic material for semiconductors, quantum computing, MRI systems, and defense.

    Qatar became the world’s second-largest producer and is now offline. Russia’s Amur Gas Processing Plant was supposed to change the math—potentially supplying 25 percent of global demand at full capacity. Gazprom started helium production there in 2021, but the facility has been hit by explosions, technical setbacks, and Western sanctions. As of early 2026, Amur is running well below capacity. Russia has increased helium exports to China—up 60 percent in 2025 alone—but the volumes remain far below what was planned. Algeria rounds out the major suppliers, but production there has been flat.

    New projects in Saskatchewan, Tanzania, and South Africa are in various stages of development. None are close to meaningful output. Greenfield helium developments typically require 7 to 10 years from exploration to production. The supply that’s missing today won’t be replaced by new sources for the rest of the decade.

    Who gets it when there isn’t enough

    Helium allocation in a shortage follows a predictable hierarchy. Essential medical uses—MRI machines, NMR systems—receive the highest protection. Defense and space applications sit immediately below. Semiconductors are high-priority industrial users but rank below medical and defense in a severe allocation scenario. Lower-value and more substitutable uses—welding, leak detection in non-critical applications, party balloons—face the sharpest cuts first.

    South Korea is under the greatest near-term strain. The country produces roughly two-thirds of the world’s memory chips and sourced 64.7 percent of its helium imports from Qatar in 2025. Samsung is the most exposed major chipmaker, with an estimated buffer of six to twelve weeks. Taiwan entered the crisis with better short-term cover—one major supplier maintained stockpiles in both Japan and the United States—but remains exposed to cost inflation if the market stays tight for months. Chipmakers can store about six weeks’ worth of supply in specialized cryogenic containers, and once insulation is depleted, the helium warms, expands into gas, and escapes. You can’t stockpile it the way you stockpile oil.

    The semiconductor equipment industry has responded by accelerating helium recycling system development. Current technology recovers 60 to 80 percent of helium used in fabrication, at installation costs of $2 to $5 million per facility. Semiconductor fabs achieve recycling rates of 95 percent or higher for some applications. But recycling reduces consumption; it doesn’t eliminate the need for fresh supply. And MRI machines—the largest single consumer—recycle at 70 to 80 percent, significantly worse than semiconductor fabs.

    The pattern

    This is the fourth major helium shortage since 2006. Shortage 1.0 in 2006 to 2007. Shortage 2.0 in 2011 to 2013. Shortage 3.0 in 2018 to 2020. Each one driven by the same combination: plant outages, demand spikes, and the structural fragility of having a nonrenewable, non-substitutable industrial gas produced as a byproduct in a handful of geographically concentrated facilities. The 2026 crisis is different in scale—one-third of global supply offline due to military conflict rather than equipment failure—but the underlying vulnerability is identical.

    Helium is the material that makes the gap between “critical resource” and “national security concern” visible. It’s not scarce in the way rare earths are scarce—controlled by one country through deliberate industrial policy. It’s scarce in a more fundamental way: the planet has a finite amount, it cannot be manufactured, it cannot be recaptured once released, and the applications that depend on it—medical imaging, advanced semiconductors, quantum computing, space launch, defense systems—are the applications that define whether a country can function at a 21st-century technological level. A gas that lifts party balloons is now determining whether Samsung can make memory chips and whether hospitals can run MRI machines. The constraint was always there. It took a war to make it visible.

    We cover the helium shortage alongside neodymium supply chains, semiconductor geopolitics, and the full landscape of critical materials that underpin modern technology across our Rare Earth Elements course—including why the most strategically important substance in advanced manufacturing is lighter than air and impossible to get back once it floats away.

  • Cobalt, Coltan, and Conflict Minerals: The State of Play in 2026

    In January 2025, the M23 rebel group—backed by Rwanda and approximately 10,000 Rwandan troops, according to UN investigators—seized Goma, the capital of North Kivu province in the eastern Democratic Republic of the Congo. More than 3,000 people were killed in less than two weeks of fighting. An estimated 2,400 Congolese soldiers surrendered en masse. Over 150 female inmates were raped and burned to death during a jailbreak in the chaos. M23 then advanced south and captured Nyabibwe, another mining hub, less than a year after seizing Rubaya—a site that harbors one of the world’s largest deposits of coltan and supplies roughly 15 percent of global tantalum production.

    In February 2026, landslides collapsed several artisanal coltan mines at Rubaya, killing at least 227 workers. It was the fourth deadly landslide Global Witness had documented at the site in 18 months. The miners were working in territory controlled by M23. The coltan they extracted was being transported into Rwanda—more than 120 tonnes per month, according to UN experts—where it was laundered and exported as Rwandan product to China, Europe, and the United States. Some of it is in the device you’re reading this on.

    That last sentence isn’t rhetoric. It’s supply chain arithmetic. The DRC produces approximately 70 percent of the world’s cobalt and holds roughly 60 percent of global coltan reserves. These minerals are essential components in the lithium-ion batteries that power electric vehicles, smartphones, laptops, and advanced weapons systems. The International Energy Agency projects that global cobalt demand will quadruple by 2030. The connection between a mine collapse in North Kivu and a phone in your pocket is not metaphorical. It is three to four intermediaries long, and nearly a billion dollars vanishes from the legal supply chain annually through the middlemen who mix illegally sourced minerals with certified ones.

    What conflict minerals actually are

    The term “conflict minerals” refers to tin, tantalum, tungsten, and gold—the “3TGs”—mined in conditions where the proceeds finance armed conflict or the minerals are extracted through forced labor. The designation originates from Section 1502 of the 2010 Dodd-Frank Act, which required U.S.-listed companies to disclose whether their products contained minerals sourced from the DRC or adjoining countries. Cobalt was not included in the original definition, though it arguably should have been—the same armed groups, child labor networks, and supply chain opacity that characterize 3TG extraction apply to cobalt with equal or greater force.

    Coltan—short for columbite-tantalite—is processed into tantalum, a heat-resistant metal used in capacitors for mobile phones, computers, medical equipment, and aerospace components. Cobalt is essential for the cathodes in lithium-ion batteries. Together, these two minerals account for a disproportionate share of the DRC’s strategic value and a disproportionate share of its human suffering. Of the estimated 255,000 Congolese mining cobalt, approximately 40,000 are children, some as young as six, working with hand tools for less than $2 per day.

    The 2025 escalation

    The M23 offensive that captured Goma in January 2025 represented the most serious military escalation in the DRC’s eastern provinces in over two decades. The fall of the provincial capital—home to over a million people—triggered a humanitarian crisis that displaced at least 100,000 from camps in the volatile east on top of the millions already displaced by decades of conflict. M23 and allied forces now control North and South Kivu, bordering Rwanda and Burundi, and much of Ituri province with its lucrative gold mines bordering Uganda.

    The mineral dimension of the conflict is not incidental. A UN official told the Security Council that coltan trade from Rubaya’s mines generates an estimated $300,000 per month in revenue for M23. Updated estimates from other UN reporting suggest the figure may be closer to $800,000 per month. “It’s not a coincidence that the zones occupied by the rebels are mining areas,” said Patrick Okenda, a researcher at Global Witness. “It takes money to wage war. Access to mining sites finances the war.”

    Rwanda’s role is particularly complicated. President Paul Kagame has acknowledged that minerals flow through Rwanda from the DRC but frames it as smuggling rather than state-sponsored extraction. A 2024 UN report documented that Uganda falsely labels DRC-sourced minerals as domestic exports. Between 2020 and 2021, Uganda exported $2.25 billion in gold despite minimal domestic production. The U.S. Treasury Department reported in 2022 that over 90 percent of the DRC’s gold was being smuggled to regional states, particularly Rwanda and Uganda, before being refined and exported to international markets through the UAE.

    The Washington Accords

    The Trump administration intervened directly in the conflict under the framework of securing critical mineral access. In June 2025, Secretary of State Marco Rubio hosted DRC and Rwandan officials to initial a preliminary accord. In December 2025, the Washington Accords for Peace and Prosperity were signed at a presidential summit, witnessed by the leaders of Angola, Kenya, and Burundi.

    The accords explicitly tied peace negotiations to mineral access for U.S. corporations. The Modern War Institute at West Point published an analysis describing the arrangement as a potential “cobalt quagmire,” warning that Washington risked being drawn into a proxy war in some of Africa’s deadliest terrain. The DRC’s President Tshisekedi had solicited a formal security pact—effectively trading mineral access for American military support—and the analysis noted that “factors that make [the DRC] an attractive node in a critical mineral supply strategy, such as resource abundance and a transactional head of state, also make it a risky place to do business.”

    European private military contractors had already failed in the theater. Several hundred Romanian contractors deployed across eastern DRC from 2022 to 2025. When M23 captured Goma, nearly 300 of them were surrounded and captured, paraded before media, and eventually repatriated through Rwanda.

    The export quota system

    In February 2025, the DRC government suspended cobalt exports for four months to address market oversupply—cobalt prices had been depressed by overproduction and reduced demand from battery chemistry shifts toward lithium iron phosphate (LFP) cathodes, which use no cobalt. In October 2025, the government introduced export quotas: companies were allocated specific monthly export volumes, with a 10 percent royalty plus a 5 percent strategic minerals levy. A 9,600-tonne “strategic reserve” was placed under the control of ARECOMS, the DRC’s new mineral regulation authority. Companies that don’t use their full allocations lose them to the government reserve starting January 2026.

    The quota system represents the DRC’s most aggressive move to control its mineral wealth. Industry analysts at CRU Group described it as “a fundamental shift from market-based supply to government-controlled allocation.” The system also mandates electronic tracking of all mineral exports through the Better Sourcing Program, a partnership with RCS Global. Whether the tracking system can actually distinguish legally sourced cobalt from conflict-sourced cobalt in a country where “legal and illegal cobalt quickly mingle,” as the Institute for Security Studies’ Oluwole Ojewale described it, is the question on which the entire framework depends.

    The supply chain problem nobody has solved

    The DRC captures approximately 3 percent of the value in the battery and EV supply chain despite supplying 70 percent of the cobalt. Almost all cobalt mined in the DRC is shipped to China for refining—China processed 77 percent of the world’s cobalt in 2022. The DRC sells raw material. China sells batteries. The value multiplier between the two ends of the chain is roughly 20 to 1.

    The DRC has ambitions to move up the chain. A Bloomberg study identified the DRC as a favorable location for battery precursor production—building a plant there would cost three times less than in the U.S. or China, cut supply-chain emissions by 30 percent, and keep more value in-country. The EU signed strategic partnerships with the DRC and Zambia on critical raw material value chains in 2023. The U.S., DRC, and Zambia signed a memorandum of understanding in 2022 to develop integrated EV battery production. None of these initiatives has yet produced a functioning refinery at scale in the DRC. The infrastructure gap—roads, electricity, skilled labor—remains enormous, and the security situation in the eastern provinces makes investment in processing capacity a proposition that requires either extraordinary risk tolerance or the kind of military guarantee that the Washington Accords are attempting to provide.

    Alternative cobalt sources are in development. Jervois Global’s Idaho Cobalt Operations targets 1,500 tonnes per year with a restart planned for Q2 2026. Fortune Minerals’ NICO Project in Canada has an estimated capacity of 1,728 tonnes per year. Global cobalt production is approximately 130,000 tonnes annually, overwhelmingly from the DRC. The alternative sources represent rounding errors.

    Battery chemistry is shifting. LFP cathodes—which contain no cobalt—are gaining market share, particularly in Chinese EVs and Tesla’s standard-range vehicles. But high-performance applications, particularly long-range EVs and consumer electronics, still require nickel-cobalt-manganese (NCM) or nickel-cobalt-aluminum (NCA) cathodes. Cobalt isn’t going away. The question is whether the supply chain that delivers it can be made less dependent on a country where 227 miners die in a landslide at a site controlled by a rebel militia backed by a neighboring government, and the coltan they extracted still makes it into your phone.

    The honest answer, in 2026, is no. Not yet. Possibly not soon.

  • China’s Rare Earth Monopoly: How One Country Cornered the Market on Modern Technology

    In April 2025, China imposed export licensing requirements on seven rare earth elements—samarium, gadolinium, terbium, dysprosium, lutetium, scandium, and yttrium—plus all their derivative compounds, metals, and magnets. Export volumes dropped roughly 74 percent within a month. Carmakers in the United States and Europe couldn’t get permanent magnets. Some cut production. Some shut down factories temporarily. European rare earth prices hit six times the Chinese domestic price—a spread so wide it essentially constituted an export tax without calling itself one. The International Energy Agency described it as supply concentration risk “becoming reality.”

    Then in October, China escalated. Five more elements added to the control list. Export restrictions extended to lithium-ion battery supply chains, synthetic graphite anode materials, and superhard materials including synthetic diamond. And—this is the part that made trade lawyers lose sleep—China applied the foreign direct product rule to rare earths for the first time. That mechanism, which the U.S. had pioneered to restrict semiconductor exports to China, now worked in reverse: products made anywhere in the world using Chinese-origin rare earth materials or Chinese rare earth processing technology required an export license from Beijing. China wasn’t just controlling what left its borders. It was claiming jurisdiction over what happened to its materials after they left.

    The controls were partially suspended in November 2025 as part of a broader U.S.-China trade negotiation, buying roughly a year of breathing room. But the message was delivered. China had demonstrated that it could, at will, disrupt the supply chains for electric vehicles, wind turbines, fighter jets, guided missiles, smartphones, MRI machines, and essentially every piece of advanced technology that relies on permanent magnets—which is most of them. And it demonstrated this not through a theoretical exercise or a diplomatic warning but by actually doing it, watching the global manufacturing base scramble, and then offering to turn it back on as a negotiating concession.

    The question everyone should be asking is not “how did China get this leverage?” The question is “how did every other country let them?”

    The strategic bet nobody noticed

    The standard version of this story starts with Deng Xiaoping reportedly saying in 1992 that “the Middle East has oil, China has rare earths.” Whether he actually said it in those exact words is debated—the original context was a visit to Bayan Obo, the world’s largest rare earth mine, in Inner Mongolia—but the policy direction was unmistakable. China decided, decades before anyone else was paying attention, that rare earth processing would be a strategic industry worth dominating.

    The decision wasn’t about mining. Rare earth elements are not geologically rare—they’re found on every continent, including in the United States, Australia, Canada, Brazil, and throughout Africa and Scandinavia. The name is misleading. What’s rare is the willingness to process them, because rare earth processing is genuinely nasty. Separating individual rare earth elements from ore requires extensive chemical processing—solvent extraction, acid leaching, ion exchange—that produces large volumes of toxic and sometimes radioactive waste. The environmental costs are enormous. The margins, historically, have been thin. And the capital investment required to build a separation facility from scratch is measured in billions of dollars and years of construction.

    China accepted those costs. Starting in the 1980s and accelerating through the 1990s and 2000s, Chinese state-supported enterprises built out the entire value chain: mining, concentration, separation, oxide production, metal refining, alloy manufacturing, and finished magnet production. They did it with lower labor costs, lower environmental standards, and state subsidies that made it effectively impossible for competitors to operate profitably. Western rare earth operations—including the Mountain Pass mine in California, which had been the world’s largest rare earth producer—shut down because they couldn’t compete on price. By the early 2010s, China controlled over 95 percent of global rare earth production.

    The genius of the strategy—if that’s the right word for a policy that also created massive environmental sacrifice zones across Inner Mongolia—was that China didn’t just dominate one link in the chain. It dominated every link. Mining the ore is step one. Separating it into individual oxides is step two. Reducing the oxides to metals is step three. Alloying the metals and manufacturing finished magnets is step four. Each step requires specialized expertise, equipment, and chemical processes that take years to develop. China built all four steps while the rest of the world was content to buy the output. By the time anyone realized the dependency was strategic rather than merely commercial, the dependency was so deep that unwinding it would take a decade at minimum.

    The numbers in 2026

    The IEA’s Global Critical Minerals Outlook reports that for 19 of 20 important strategic minerals, China is the leading refiner, with an average market share of 70 percent. For rare earths specifically, the concentration is even more extreme. China processes approximately 90 percent of the world’s rare earth oxides. It manufactures roughly 85 percent of global NdFeB permanent magnets. It controls a near-monopoly—95 percent or above—in precursor cathode materials and lithium iron phosphate cathode materials for batteries.

    The European Central Bank estimated that over 80 percent of large European firms are no more than three intermediaries away from a Chinese rare earth producer. That’s not a supply chain. That’s a dependency relationship with a single counterparty who has demonstrated both the capability and the willingness to restrict supply for geopolitical purposes.

    The U.S. position is marginally better but not fundamentally different. MP Materials operates the Mountain Pass mine in California—the only active rare earth mining operation of scale in the country—and in 2024 produced a record 45,000 metric tons of rare earth oxide concentrate. Its Independence facility in Fort Worth, Texas, began trial production of sintered NdFeB magnets in late 2025, with a target capacity of about 1,000 metric tons per year. Global NdFeB magnet production is roughly 220,000 to 240,000 metric tons annually. MP Materials’ output, at full capacity, would represent less than half a percent of global supply. The Pentagon awarded a conditional $620 million loan to Vulcan Elements and ReElement Technologies to scale domestic magnet production. Noveon Magnetics is currently the only active rare earth magnet manufacturer in the United States and announced a partnership with Australian producer Lynas Rare Earths to build a domestic supply chain. All of these efforts are real and necessary and collectively amount to a rounding error relative to China’s installed capacity.

    Why you can’t just “build more mines”

    The most common response to the rare earth supply chain problem—from politicians, editorial writers, and people who haven’t spent time understanding the chemistry—is some version of “we have rare earths too, we should just mine them.” The problem is that mining is the easy part. It’s the processing that creates the monopoly, and processing is where China’s advantage is nearly insurmountable in the short term.

    Separating rare earth elements from each other is one of the most chemically demanding industrial processes in existence. The 17 rare earth elements have nearly identical chemical properties—that’s why they’re grouped together—which means separating, say, neodymium from praseodymium from dysprosium from terbium requires hundreds of stages of solvent extraction, each stage achieving only a marginal enrichment. The process consumes enormous volumes of hydrochloric acid, sodium hydroxide, and organic solvents, and produces proportional volumes of chemical waste. Building a separation plant from scratch takes three to five years and costs over a billion dollars. Qualifying the output to meet the specifications required by magnet manufacturers—purity levels of 99.5 percent or higher for individual oxides—adds additional time and expertise.

    China has spent forty years optimizing these processes. The rest of the world is starting from approximately zero, and the engineers and chemists who know how to run a rare earth separation plant at commercial scale are overwhelmingly in China. You can build the facility. Staffing it with people who know what they’re doing is a different problem.

    The 2010 precedent nobody learned from

    This isn’t even the first time China used rare earth export controls as geopolitical leverage. In 2010, following a territorial dispute with Japan over the Senkaku/Diaoyu Islands, China informally restricted rare earth exports to Japan—the world’s largest rare earth consumer at the time and a major manufacturer of permanent magnets and electronics. The embargo was never officially acknowledged but was widely reported by Japanese importers and confirmed by market data showing a sudden, dramatic drop in shipments.

    The global response was alarm, hand-wringing, and a burst of investment in alternative supply chains that faded as soon as prices normalized. The U.S. opened the Mountain Pass mine back up. Australia’s Lynas Rare Earths built a processing facility in Malaysia. The WTO ruled against China’s export quotas in 2014. China lifted the quotas. Prices came down. And the structural dependency went essentially unchanged because the alternative projects were more expensive than Chinese supply and couldn’t compete once the price pressure was removed.

    Fifteen years later, the same vulnerability was exploited with the same playbook, except this time the controls were more comprehensive, the extraterritorial provisions were new, and the geopolitical context—a genuine strategic competition between the U.S. and China rather than a bilateral territorial dispute—suggests the restrictions will recur regardless of any temporary suspension.

    What the response actually looks like

    The EU passed the Critical Raw Materials Act and launched the RESourceEU initiative for joint purchasing and stockpiling. The European Parliament called China’s actions “coercive” and demanded acceleration of domestic mining projects and bilateral partnerships with alternative supplier nations. Germany committed to €35 billion in resilience and deterrence programs that include rare earth supply chain diversification.

    The U.S. is pursuing a multi-track strategy: domestic mining and processing (MP Materials, Vulcan Elements), allied supply chains (Lynas partnership with Noveon), tariffs on Chinese magnets (25 percent, scheduled for 2026), and stockpiling. The Pentagon’s Defense Logistics Agency maintains a strategic reserve of certain rare earth materials, though the size and adequacy of the reserve are classified.

    But here’s the honest assessment: none of these efforts will meaningfully reduce China’s leverage within the next five years. The processing infrastructure takes years to build, the workforce takes years to train, the qualification cycles for defense-grade materials take years to complete, and the volumes required to replace Chinese supply are orders of magnitude beyond what any current Western facility can produce. The 2025 export controls demonstrated that China can inflict significant economic damage on the global manufacturing base essentially at will—and that the threat of doing so is itself a powerful bargaining chip that costs Beijing nothing to maintain.

    The rare earth monopoly is not a market failure. It’s a strategic outcome, achieved through decades of deliberate industrial policy, tolerated by decades of Western indifference, and now leveraged with a precision that makes it one of the most effective instruments of economic statecraft in the 21st century. The question of how to respond is real and urgent. The question of whether a response is possible in time to matter during the current geopolitical cycle is considerably less certain.

    We cover China’s rare earth strategy—along with the science, processing chemistry, and geopolitics of 36 critical elements from lithium to uranium—across our Rare Earth Elements & Critical Minerals course. If the foreign direct product rule applied to magnets changed your understanding of how supply chain warfare works, the course goes element by element through every chokepoint.

  • How Neodymium Magnets Are Made (And Why They Matter for Everything From Wind Turbines to F-35s)

    Every electric vehicle on the road has them. Every wind turbine spinning on a ridge in west Texas has them. Every pair of AirPods, every MRI machine, every hard drive, every guided missile in the Pentagon‘s inventory has them. Neodymium-iron-boron magnets—NdFeB if you’re reading a spec sheet, “neo magnets” if you’re not—are the strongest permanent magnets commercially available, and they are so deeply embedded in modern technology that removing them from the supply chain would be roughly equivalent to removing concrete from construction. You could technically build things without them. You just wouldn’t want to see what you’d get.

    The thing is, almost nobody knows how they’re made. The manufacturing process is genuinely fascinating—part metallurgy, part materials science, part geopolitical thriller—and understanding it explains why these magnets are at the center of a supply chain crisis that involves export controls, Pentagon loans, tariff threats, and the kind of great-power competition that used to be about oil and is now about a silvery metal most people can’t pronounce.

    What makes them special

    A neodymium magnet is an alloy of three elements: neodymium (a rare earth element, atomic number 60), iron, and boron. The compound—Nd2Fe14B—forms a tetragonal crystal structure that was discovered independently by General Motors and Sumitomo Special Metals in 1984, which is the materials science equivalent of two people showing up to a party wearing the same outfit except the outfit happens to reshape global manufacturing for the next four decades.

    What makes this crystal structure so magnetically powerful is its exceptionally high magnetocrystalline anisotropy—the atomic-level property that determines how strongly a material resists demagnetization. In plain language: the crystal lattice is shaped such that the magnetic domains align along a single preferred axis with extreme reluctance to flip. The energy density is roughly ten times higher than a standard ferrite magnet, which means a neodymium magnet the size of a quarter can do the work of a ferrite magnet the size of a coffee mug. That size-to-strength ratio is why they ended up everywhere. When you need a powerful magnetic field in a small package—an EV motor, a drone, a missile guidance system, an earbud—there is no practical substitute.

    How they’re actually made

    The manufacturing process is powder metallurgy, and every step matters. Screw up the particle size, the alignment pressure, or the sintering temperature by a small margin and you get a mediocre magnet instead of a great one. This is not an industry where you can wing it.

    It starts with strip casting. The raw materials—neodymium (often with some praseodymium substituted in because it’s cheaper and chemically similar), iron, and boron, plus small additions of dysprosium or terbium for high-temperature applications—are melted together in a vacuum induction furnace at around 1,300°C. The molten alloy is poured onto a rapidly spinning, water-cooled copper roller, which solidifies it into thin strips. The rapid cooling is critical: it produces a fine-grained microstructure that’s optimized for the next step.

    Those strips go through hydrogen decrepitation—you expose them to hydrogen gas, which diffuses into the grain boundaries and causes the alloy to crack apart into coarse chunks. This is nature doing the first stage of size reduction for you. From there, the chunks go into a jet mill operating in a nitrogen atmosphere, where high-pressure gas streams grind the material into an extremely fine powder with an average particle size of about 3 microns. That’s roughly the size of a red blood cell. The nitrogen atmosphere prevents oxidation, which would ruin the magnetic properties—neodymium is ferociously reactive with oxygen, which is also why the finished magnets need protective coatings, but we’ll get there.

    Now comes the step that makes or breaks the magnet: magnetic field alignment and pressing. The powder goes into a mold, and a powerful external magnetic field—several tesla—is applied. This field physically rotates the tiny crystalline particles so their easy magnetization axes all point the same direction. The aligned powder is then compressed under enormous pressure. The alignment quality during this step directly determines the magnet’s maximum energy product—the BHmax value that shows up on the spec sheet and tells an engineer how much magnetic work the magnet can do per unit volume. A poorly aligned magnet with the exact same chemical composition will be measurably weaker than a well-aligned one. The process matters as much as the recipe.

    The compressed “green compact” is then sintered in a vacuum furnace at approximately 1,050°C. Sintering fuses the powder particles together without fully melting them—it’s the difference between welding and soldering, conceptually—creating a dense, solid block with the internal crystal alignment locked in place. After sintering, the magnet goes through a two-stage annealing process at around 900°C and then 600°C, which relieves internal stresses and dissolves unstable phases that would degrade performance over time.

    At this point you have a block of sintered NdFeB that is extremely hard, extremely brittle, and not yet the shape anyone needs. Machining comes next—diamond-tipped saws and grinding wheels cut the blocks into the precise geometries required for specific applications: arcs for motors, discs for speakers, rings for sensors. This is delicate work because the material shatters like ceramic if you look at it wrong. The kerf loss (material wasted in cutting) is a meaningful cost factor, especially when neodymium oxide costs upward of $70 per kilogram.

    Then: coating. Unprotected NdFeB corrodes aggressively. The neodymium-rich grain boundary phase reacts with moisture and oxygen, forming hydroxides that literally cause the magnet to disintegrate over time—structural failure from the inside out. The standard solution is a multi-layer nickel-copper-nickel electroplating, though epoxy coatings, zinc plating, and parylene are used depending on the application environment.

    Finally, the magnet is magnetized. A pulse magnetizer blasts it with a field of approximately 5 tesla, which saturates the aligned domains and produces a permanent magnet ready for installation. The whole process, from raw oxide to finished magnet, involves dozens of precision-controlled steps, and the yield at each stage matters. This isn’t assembling a product. It’s growing one.

    Why this is a geopolitical problem

    China produces roughly 85% of the world’s NdFeB magnets. Not 85% of the neodymium—85% of the finished magnets. Japan and Vietnam account for most of the rest. The United States, as of early 2025, produced approximately zero sintered NdFeB magnets at commercial scale. That’s a supply chain that has the resilience of a house of cards in a wind tunnel, and everyone involved knows it.

    The concentration isn’t accidental. China made a strategic bet on rare earth processing decades ago—Deng Xiaoping reportedly said in 1992 that the Middle East has oil and China has rare earths—and then spent thirty years building out the mining, separation, refining, alloying, and magnet manufacturing infrastructure while everyone else was content to buy cheap finished products. The result is a vertically integrated supply chain that’s extraordinarily difficult to replicate quickly, because it’s not just the magnet factory you need. It’s the solvent extraction plant, the oxide separation facility, the metal reduction furnace, the alloy production line, and the workforce that knows how to run all of it. Each step has its own chemistry, its own equipment, its own failure modes.

    The consequences of this concentration became concrete in April 2025, when China imposed export licensing requirements on dysprosium, terbium, and finished magnets. Export volumes reportedly dropped roughly 74% in May compared to the prior year. These aren’t abstract tariff games—dysprosium is the element that gives NdFeB magnets their high-temperature performance, and without it, the magnets in an F-35’s flight control actuators, an MQ-9 Reaper drone’s guidance system, or a Virginia-class submarine’s propulsion motor would lose their magnetic properties at operating temperatures. The Pentagon noticed.

    The U.S. response has been a scramble. MP Materials—which operates the Mountain Pass mine in California, the only active rare earth mining operation of scale in the country—opened a magnet manufacturing facility in Fort Worth, Texas, in 2025. They began trial production of automotive-grade sintered NdFeB magnets late that year, with a target capacity of about 1,000 metric tons per year. For context, global production is somewhere around 220,000 to 240,000 metric tons annually. So the Fort Worth facility, at full capacity, would represent roughly 0.4% of global supply. It’s a start. It’s not a solution.

    The Pentagon, meanwhile, awarded a conditional $620 million loan to Vulcan Elements and ReElement Technologies to scale domestic magnet production for defense applications. President Trump publicly threatened 200% tariffs on Chinese goods if Beijing restricted rare earth magnet shipments. The EU passed the Critical Raw Materials Act. Everyone is suddenly very interested in a supply chain they ignored for thirty years.

    Why there’s no easy substitute

    The reason this matters so much is that there is no drop-in replacement for NdFeB in most high-performance applications. Ferrite magnets are cheap and abundant, but they’re roughly one-tenth the energy density—you’d need a motor ten times the size to produce the same torque, which defeats the purpose of using permanent magnets in the first place. Samarium cobalt magnets handle high temperatures better but cost significantly more and use cobalt, which has its own supply chain problems centered on the Democratic Republic of Congo. Researchers have explored ferrite-based alternatives, iron nitride, and manganese-based compounds, but none have come close to NdFeB’s combination of magnetic strength, manufacturability, and cost at scale.

    The substitution problem is especially acute in two sectors: electric vehicles and wind turbines. A typical EV traction motor uses 1 to 2 kilograms of NdFeB magnets. A direct-drive offshore wind turbine—the kind being deployed at scale in the North Sea and off the U.S. Atlantic coast—uses roughly 600 kilograms per megawatt of capacity. If you’re planning to electrify the global vehicle fleet and simultaneously triple offshore wind capacity by 2040, you need a lot more neodymium than currently exists in the processing pipeline. The bottleneck isn’t the ore. It’s the processing, the separation, and the magnet manufacturing—and those bottlenecks are sitting in a country that has demonstrated a willingness to use them as leverage.

    This is the kind of constraint that doesn’t show up in the optimistic energy transition models, and it’s the kind of thing that makes the difference between a plan that works on a slide deck and a plan that works on a random Tuesday when the supply ship doesn’t arrive.

    We cover neodymium magnets—along with 35 other critical elements and minerals, from lithium to uranium to gallium nitride—across 36 lectures in our Rare Earth Elements & Critical Minerals course. If you want the full supply chain story, from the Bayan Obo mine to the inside of an F-35 actuator, that’s where it lives.
