What Is Tungsten
Tungsten is element 74 — and the only element whose chemical symbol comes from a different name entirely. W stands for Wolfram, the German word for the ore tungsten was first extracted from. Dense, grey-white, and harder than almost anything that occurs naturally, tungsten is defined by two physical properties that place it in a category of its own: it has the highest melting point of any metal — 3,422 degrees Celsius, hot enough that nothing else can contain a tungsten melt — and it is the hardest of all metals by tensile strength.
Those two properties together determine where tungsten is used. Armor-piercing munitions use tungsten heavy alloy (a dense composite material that delivers kinetic energy through mass and velocity) in the penetrators — the solid metal rods that punch through tank armor and hardened fortifications. Nothing else achieves equivalent density and hardness at the temperatures generated on impact. Missile components and aircraft counterweights that must survive extreme heat and mechanical stress depend on the same properties. Cutting tools and drill bits — from surgical instruments to oil well drilling equipment — rely on cemented carbide (a compound of tungsten and carbon harder than steel), which accounts for approximately 60% of all tungsten consumption globally. And inside semiconductor chips, tungsten is used for the microscopic interconnects (the internal wiring that connects transistors at nanoscale densities) because it handles the heat generated at dimensions where other metals would fail.
Tungsten is not a byproduct of something else. It is mined directly from wolframite and scheelite ore deposits. The ore exists in multiple countries. The chokepoint is not in the ground. It is in the processing infrastructure built over decades in China — and in the export controls Beijing has now placed on that processing chain.
Plain English
Tungsten is the hardest, hottest-running metal on earth. It goes into the tip of every armor-piercing round, the cutting edge of every industrial drill bit, and the wiring inside chips. Nothing else does what it does at the temperatures and pressures where it operates. China controls the processing chain. January 1, 2027 is the deadline by which the US defense industry must stop using Chinese tungsten. That deadline is eight months away.
Where It Comes From
China controls approximately 80% of global tungsten mine output and a higher share — closer to 85–88% — of refined tungsten product supply. The dominance is not geological accident. It is the result of decades of deliberate industrial policy: China restricted tungsten ore exports years ago to force value-added processing onshore, building the world's largest integrated tungsten supply chain from mine to finished carbide. Every step of that chain — mining, concentration, APT production (ammonium paratungstate — the primary intermediate compound produced by dissolving and reprecipitating tungsten from ore, the global benchmark for tungsten pricing), tungsten oxide, metal powder, carbide, and finished tooling — is predominantly Chinese.
Outside China, the significant producers are Portugal (Almonty's Panasqueira mine, one of Europe's oldest continuously operating tungsten operations), Spain (Saloro's Barruecopardo mine), Vietnam (Masan Resources' Nui Phao, one of the largest non-Chinese tungsten deposits globally), and Russia (third-largest producer globally, now largely cut off from Western markets due to sanctions). The United States has produced no tungsten since 2015, when the last domestic mine closed because Chinese prices made domestic mining uneconomical.
The most significant development in the Western tungsten supply chain in decades occurred on March 16, 2026: Almonty Industries completed Phase 1 commissioning of the Sangdong Tungsten Mine in Gangwon Province, South Korea — returning one of the world's historically largest tungsten deposits to production after more than 30 years of dormancy. Phase 1 processes approximately 640,000 tonnes of ore per year, yielding roughly 2,300 tonnes of tungsten concentrate annually. Phase 2, targeting 4,600 tonnes per year, is expected in 2027. At full capacity, Sangdong is designed to supply approximately 40% of Western tungsten demand outside China.
China's 2026 export policy adds a further layer. Beijing has restricted tungsten exports to a whitelist of just 15 approved firms through 2027. Chinese APT exports fell from 782 tonnes in 2024 to just 243 tonnes through November 2025. Delivery cycles for tungsten products in Japan have reportedly extended from 3 months to 9 months. European carbide and powder suppliers are already months behind on deliveries.
Plain English
China mines 80% of the world's tungsten and processes even more of it. The West's most credible response just started production two months ago in South Korea. It targets 40% of Western demand at full capacity — years from now. The gap between what January 2027 requires and what currently exists is the market the price is pricing.
Why It Matters Right Now
The defense application is direct and legislated. Tungsten heavy alloy is the material used in penetrators — the dense metal rods inside armor-piercing munitions that defeat tank armor and hardened fortifications through kinetic energy rather than explosives. Every significant Western military uses tungsten penetrators. There is no equivalent-performance substitute at the required density. Depleted uranium is the only alternative, and it carries handling, storage, and political complications that tungsten does not.
But the legislation is what makes this a timed story rather than just a structural one.
DFARS 252.225-7052 (Defense Federal Acquisition Regulation Supplement — the procurement rules governing US defense contracts), implementing 10 U.S.C. §4872, becomes fully binding on January 1, 2027. The rule prohibits US defense contractors from delivering under any Department of Defense contract any tungsten metal powder, tungsten heavy alloy, or any component containing tungsten heavy alloy if any stage of its production occurred in China, Russia, Iran, or North Korea. Mining. Refining. Melting. Fabrication. Any stage. The restriction covers the entire supply chain, not just the final product.
This is not a future proposal. It is existing law, published in the Federal Acquisition Regulation, with enforcement mechanisms including contract termination and False Claims Act liability (the federal statute that imposes penalties on contractors who submit false claims to the government). The Defense Logistics Agency has been stockpiling tungsten — with plans to acquire up to 2,040 tonnes in fiscal year 2025 alone — specifically in anticipation of this deadline. The Pentagon has publicly told defense contractors to begin applying for waivers now rather than in 2027, because the waiver process will be overloaded.
The industrial supply chain tells a parallel story that the defense headline obscures. Approximately 60% of global tungsten consumption goes into cemented carbide for cutting tools, drill bits, and wear-resistant components — none of which is defense-related. European carbide manufacturers are already months behind on deliveries. Japanese semiconductor companies have been notified of 9-month delivery timeline extensions. The tightness is cascading through manufacturing supply chains that have nothing to do with weapons.
Plain English
A US law banning Chinese tungsten from defense contracts takes effect in eight months. The Pentagon is stockpiling. Defense contractors are applying for waivers preemptively. And separately from defense, the industrial supply chain — cutting tools, drill bits, chip interconnects — is already behind on deliveries. The deadline is the acute story. The industrial disruption is the chronic one running underneath it.
One Market, Two Prices, One Deadline
Here is the contradiction the tungsten market is currently presenting: the Chinese domestic APT price has corrected approximately 35% from its March 2026 peak. SMM daily market commentary describes a domestic market in the doldrums — demand softened, long-term contract prices cut repeatedly, one major Guangdong enterprise abandoning fixed contract pricing entirely in May 2026 and switching to spot negotiation. In China, there is too much tungsten chasing too few domestic buyers at current prices.
And yet APT CIF Rotterdam — the Western import benchmark — holds at approximately $3,050 per mtu (metric ton unit, the standard tungsten pricing unit equal to 10 kilograms of tungsten trioxide). The Chinese domestic price sits at approximately $1,338 per mtu converted from yuan. The gap is roughly 3 to 1. It has not closed despite the domestic correction.
That gap is not freight. It is the market pricing two completely different supply realities for the same material. Chinese domestic tungsten is constrained by softening demand. Western tungsten is constrained by the 15-firm export whitelist — meaning Chinese producers, even those with available inventory and willing buyers in the West, cannot export freely. The domestic oversupply cannot reach Western markets. The Western scarcity cannot be relieved by Chinese domestic availability. Two prices. Two markets. One deadline that makes the separation permanent for one class of buyer.
After January 1, 2027, a US defense contractor cannot use Chinese-origin tungsten regardless of price. The domestic China correction is irrelevant to that contractor. The lower domestic price is the correct price for a Chinese domestic buyer. The $3,050 per mtu Western price is the correct price for a Western buyer who cannot legally source Chinese material for defense applications and is competing for a non-Chinese supply that is structurally insufficient at current volumes.
Plain English
China's domestic tungsten price corrected. The Western price didn't follow. Export controls mean domestic oversupply can't reach Western buyers. After January 1, 2027, US defense contractors can't use Chinese tungsten regardless. One market correcting. The other market repricing permanently. That's not a temporary spread. That's the new structure.
What the Price Has Done
For decades before 2023, tungsten APT traded below $250 per mtu in Rotterdam. Chinese production dominance kept prices contained through chronic oversupply — the same mechanism that eliminated US domestic tungsten production by 2015. The West outsourced its tungsten supply chain entirely, trading price efficiency for structural dependency.
The first move came in 2023 as China introduced export licensing controls on tungsten products — not an outright ban, but a government approval requirement for each shipment. Combined with reductions in domestic mining quotas, prices began moving out of their long-term range. APT Rotterdam climbed from the sub-$250 per mtu baseline toward $300–400 per mtu as buyers began pricing in supply risk.
January 2026 was the inflection. China restricted tungsten exports to just 15 approved firms — the whitelist policy. APT FOB China immediately jumped to $1,090–1,150 per mtu. Rotterdam CIF prices surged from approximately $900–940 per mtu in January to $1,650–1,900 per mtu by mid-February as Western buyers absorbed the supply shock.
March 2026 was the peak. SMM domestic China APT reached the equivalent of approximately $1,500 per mtu converted. Rotterdam prices were at or near record highs. May 2026: the Chinese domestic market has corrected approximately 35% from the March peak, with SMM domestic APT at approximately $1,338 per mtu converted. Rotterdam CIF holds at $2,900–3,200 per mtu, averaging approximately $3,050 per mtu. Rotterdam APT is up approximately 900% over the trailing 12 months. The domestic China correction has not closed the 3x spread between domestic and Western prices — because export controls prevent the domestic oversupply from reaching Western buyers.
Plain English
Cheap for decades. China tightened the licensing screws from 2023 onward. Prices climbed. China cut exports to 15 approved firms in January 2026. Prices surged 900% over 12 months. The Chinese domestic market then corrected as domestic demand softened. The Western market didn't follow — because export controls mean Chinese domestic oversupply can't reach Western buyers. The 3x spread between domestic and Western prices is structural, not temporary.
The Bottom Line
The well-known story is the price chart — Rotterdam APT up 900% over the trailing 12 months, China restricting exports to 15 firms, the Western market in a historic supply squeeze. That story is accurate and increasingly reflected in procurement decisions.
The underappreciated story is the deadline. January 1, 2027 is not a market risk or a policy proposal. It is binding law, already published in the Federal Acquisition Regulation, with contract termination and False Claims Act liability as enforcement mechanisms. After that date, any tungsten that touched Chinese soil at any stage of its production chain — mining, refining, melting, fabrication — cannot appear in a US defense contract. The Pentagon is stockpiling. Contractors are applying for waivers preemptively because the waiver process will be overwhelmed. The Defense Logistics Agency acquired 2,040 tonnes in fiscal year 2025 specifically for this reason.
The Chinese domestic correction in May 2026 changes nothing for a US defense contractor. Chinese domestic oversupply cannot reach Western defense buyers after January 1, 2027 regardless of price. The $3,050 per mtu Western price is not a market inefficiency. It is the correct price for a material that is structurally short in Western markets and legally prohibited in defense applications in eight months.
Plain English
The price tells you there's a problem. The law tells you the problem has a hard deadline. The stockpiling tells you the Pentagon knows the non-Chinese supply isn't there yet. Eight months. Sangdong is the best answer the West currently has. It started two months ago. It will take years to reach full capacity. That gap — between what the law requires on January 1, 2027 and what non-Chinese supply can currently provide — is what $3,050 per mtu is paying for.
