This is a note on a metal most readers have never knowingly held, a dependency the industrial strategists of three continents have spent twenty years deferring, and the slow structural lesson that a commodity which was never priced like a commodity cannot be defended like one either.
What tungsten actually is
Tungsten is element 74, symbol W, named after the German Wolfram rather than the Swedish tung sten (“heavy stone”) from which the English word descends. It is the heaviest practically usable metal in the periodic table at 19.3 grams per cubic centimetre, nearly identical in density to gold. It has the highest melting point of any pure metal at 3,422 degrees Celsius, which is roughly the surface temperature of a cool star. Its tensile strength at high temperature is unmatched. Alloyed with cobalt as sintered cemented carbide, it becomes the industrial world’s standard cutting edge. Alloyed with nickel and iron as a heavy alloy (sometimes called a WHA, tungsten heavy alloy), it becomes the kinetic penetrator fired by NATO tank guns that do not use depleted uranium. In its purest form, drawn as thin wire, it was the filament that lit the twentieth century; in its chemical form as sodium tungstate and ammonium paratungstate, it is the feedstock from which every other tungsten product is made.[1][2]
There are no substitutes that work across all three domains at once. For a drill bit cutting a jet engine turbine disc out of a nickel-cobalt superalloy, nothing performs like tungsten carbide. For a long-rod penetrator that must punch through composite armour at nearly a mile per second without disintegrating, nothing short of depleted uranium rivals a sintered tungsten heavy alloy, and most of NATO Europe, Japan, and South Korea have politically ruled out depleted uranium. For a radiation shield that must sit inside the human throat during a cancer treatment, nothing combines density, machinability, and biological inertness like tungsten.
A metal that is this indispensable and this difficult to substitute does not behave like a commodity. It behaves like a state asset. Which is, in practice, what it has become.
The dependence that quietly matured
The industrial geography of tungsten is one of the clearest small maps of twenty-first century concentration. China produces, on current United States Geological Survey figures, between eighty and eighty-three percent of the world’s mined tungsten each year. The next-largest producer is Vietnam, with roughly five to six percent, almost entirely from a single mine — the Núi Pháo complex in Thái Nguyên province, operated by Masan High-Tech Materials. Russia produces roughly two to three percent, mostly from deposits in Primorsky Krai and Buryatia whose logistics now run largely through Chinese buyers. Mongolia, Austria (the Mittersill mine in the Hohe Tauern), Spain, Portugal (the Panasqueira mine, in continuous operation since 1898), Bolivia, and Rwanda between them account for most of the remainder.[3][4]
Refining is more concentrated still. Mined tungsten, which arrives as scheelite or wolframite concentrate at roughly sixty-five percent tungsten trioxide, has to be converted chemically into ammonium paratungstate (APT) before it is of any industrial use. APT plants are not cheap, not clean, and not easily permitted in Europe or North America. Roughly eighty-five to ninety percent of the world’s APT capacity sits in China, concentrated in Jiangxi, Hunan, and Henan. Masan’s plant in Thái Nguyên is the only serious non-Chinese APT line of global scale. Austria’s Wolfram Bergbau- und Hütten in Mittersill operates a smaller line largely for Plansee’s own tooling. The Global Tungsten & Powders plant in Towanda, Pennsylvania — a subsidiary of Austria’s Plansee group — is the only serious APT producer in North America and is tiny by Chinese standards.[5]
This was not an accident. The Chinese tungsten belt in Jiangxi and Hunan has been worked since the Qing dynasty. Beijing has treated the metal as strategic for most of the People’s Republic’s existence: it was placed under state export quota as early as the 1980s, under rare-earth-style discipline in the 2000s, and under a formal National Reserve regime in the 2010s. The Soviet Union maintained a comparable discipline around its own tungsten through the Cold War; the West did not. When the Pine Creek mine in California closed in 1990, when the Mittersill production was absorbed into private holdings, when the European Union’s own tungsten reserves (in Portugal, Spain, Austria, the Czech Republic, Sweden) were quietly left to run on inertia, the Western industrial state effectively agreed to buy the finished metal from someone else. For thirty years that someone else was always China. The decision was never debated. It did not need to be, because the metal was cheap.
The licence drawer closes
What changed is that Beijing stopped pretending the metal was ordinary.
In September 2024 the Chinese Ministry of Commerce published a dual-use export control list that, for the first time, formally restricted the export of tungsten metal, tungsten carbide, tungsten alloys, and tungsten products used in armour, kinetic penetrators, superalloys, and semiconductor manufacturing. In February 2025 the Ministry extended the list to add further categories, including specific tungsten-containing precursors used in high-temperature coatings and nuclear applications. In practical terms this does not mean an outright ban. It means that each export now requires an individual licence, that the licence must identify end-use and end-user, and that the licensing process is routinely used as a political instrument. For most buyers outside China, that is a worse condition than a ban, because a ban is at least a visible fact around which an industrial strategy can be organised. A licence regime is weather. It fluctuates. It punishes without announcement.[6][7]
The parallel with gallium, germanium, graphite, and antimony is close but imperfect. Those earlier controls were, in part, reciprocity for United States semiconductor restrictions. Tungsten is of a different order of consequence. Gallium and germanium are inputs into a handful of high-end chips. Tungsten is an input into the entire machine shop of industrial civilisation. The restriction of its export is not, in the Chinese reading, retaliation for a specific American policy. It is the quiet correction of a historical anomaly in which a strategic metal was treated as a commodity because the state that controlled it chose not to notice. In 2024 the state began to notice.
What breaks first
A single-source dependency breaks at its most inelastic point first, not at its largest.
The most inelastic point for tungsten is Western artillery and armour production. A 120-millimetre tank gun kinetic energy round of the NATO standard (the German DM63 and DM73 families, the French OFL-F2, the British CHARM-type training variants, Rheinmetall’s KE2020 Neo) uses a sintered tungsten heavy alloy penetrator around sixty-five centimetres long, weighing between four and five kilograms. A single Leopard 2-class battalion’s nominal combat load is on the order of several hundred rounds. European tungsten-penetrator production is concentrated in a small number of lines in Germany (Rheinmetall), the Netherlands (Eurometaal / joint programmes), France (Nexter, now KNDS), and Sweden (BAE Bofors), all of them historically dependent on Chinese paratungstate for the heavy alloy feedstock. The 2024 and 2025 export licence regime has already begun to lengthen lead times on APT-based powders. Rheinmetall has publicly flagged tungsten supply as a bottleneck in its ammunition expansion plan. In a sustained European defensive war on the scale of the current eastern frontier, the structural bottleneck is not shell casings or propellant. It is penetrators.[8]
The second inelastic point is high-temperature machining. The jet engine industry — GE Aerospace, Pratt & Whitney, Rolls-Royce, Safran, MTU — machines turbine discs and blades from nickel and cobalt-based superalloys that cannot be cut economically with anything other than tungsten carbide. A single LEAP-class engine family requires thousands of carbide tool-tips over its production run. Automotive tooling, oil and gas drill bits, and semiconductor wafer dicing all draw on the same global carbide supply, dominated by companies (Sandvik, Kennametal, IMC/Iscar, Mitsubishi Materials, Sumitomo) that themselves source most of their APT precursor from Chinese chemistry. A twenty percent squeeze on Chinese APT exports does not stop these plants. A sustained forty percent squeeze does.
The third inelastic point is semiconductor manufacturing. Modern leading-edge logic processes use tungsten extensively in contact plugs, vias, and increasingly in word-line structures and middle-of-line interconnects as copper runs out of thermal headroom. Applied Materials, Lam Research, and ASM International all build deposition equipment whose consumables and process chemistries assume tungsten-based precursors (hexafluoride and chloride forms derived from APT). Taiwan’s TSMC and South Korea’s Samsung operate under policy regimes that currently permit them continued access to Chinese tungsten chemistries, but the licence regime now sits above those regimes and can be adjusted at political speed.
Three sectors, three bottlenecks, one chemistry, one state.
The alternatives, and their limits
The alternatives to Chinese tungsten exist, but they are small, slow, and expensive to accelerate.
Vietnam. The Núi Pháo mine and its integrated downstream chemistry at Thái Nguyên is the only non-Chinese tungsten complex that operates at a scale comparable to a mid-sized Chinese plant. It currently supplies on the order of a quarter of the world’s non-Chinese APT and is politically positioned between a Vietnamese government with its own careful relationship to Beijing, a Czech-owned minority stake, and a long-standing commercial relationship with Starck in Germany. Vietnam can meaningfully grow its output. It cannot replace China.
Portugal. Panasqueira is one of the most storied tungsten mines in the world, in production since 1898. Current output is on the order of eight hundred to a thousand tonnes of tungsten trioxide equivalent a year, a small fraction of global demand. The deposit has decades of life at current rates. It is not a monument. It is also not, by itself, a source of continental independence.
Austria. Mittersill, operated by Wolfram Bergbau- und Hütten within the Plansee group, supplies Plansee’s captive tooling and some external customers. It is well-run and strategically embedded. It is also small.
Spain. The La Parrilla and Barruecopardo tungsten operations in Extremadura and Salamanca have moved in and out of production over the last decade as prices wobbled. They can be revived. They cannot be scaled in one planning cycle.
Bolivia, Rwanda, Mongolia. All three produce real tonnage. All three operate in logistical and governance environments that make them useful marginal suppliers, not strategic backbones.
Australia and Canada. Both countries have well-mapped deposits (Mount Carbine, Dolphin, Cantung) and no serious domestic refining chain. Australia’s revived Dolphin mine on King Island and the Molyhil project in the Northern Territory can produce concentrate. The APT problem — the chemistry, the permitting, the environmental tail — remains unresolved and unlikely to be solved on a Pacific timeframe.
Recycling. Secondary tungsten, principally from end-of-life carbide inserts and tool-steel scrap, already supplies roughly a quarter of global demand through a well-developed recycling industry (Wolfram, Kennametal, Sandvik). It cannot be meaningfully doubled in a decade. The scrap flow is what it is.
The total non-Chinese capacity, mobilised at war-time intensity, cannot deliver more than roughly a third of current global demand within five years, and that is a generous reading. The arithmetic is unforgiving.
What this says about the next phase of trade
The structural lesson of tungsten is not an energy transition lesson or a technology lesson. It is a political-economy lesson about which commodities are commodities and which are instruments.
Not every metal is a market. Lithium, copper, nickel, iron ore — all of these have deep spot markets, multiple serious producers, functioning price discovery, and recognisable storage dynamics. Tungsten does not. There is no serious tungsten futures contract. The published APT price is a reference number collected by trade press from a thin pool of transactions. The actual metal moves through long-term contracts and intra-group transfers that most of the industry prefers not to describe. A good faith shipping clerk in Rotterdam could follow a container of iron ore through its full chain. The same clerk could not reliably say where the tungsten in last month’s carbide shipment was mined.
Chokepoints migrate upstream faster than defence. The West’s critical-raw-materials conversation has repeatedly discovered its chokepoints too late. Rare earth magnets were a 2010 crisis understood as a crisis in 2022. Gallium and germanium were a 2023 announcement understood as a shortage in 2024. Tungsten is a 2024-2025 restriction that will be fully understood as a bottleneck when European artillery production hits its ceiling later this decade. The pattern is consistent: a one-source upstream dependency announces itself slowly, and the policy response arrives one war late.
State capacity is the actual industrial strategy. China’s dominance in tungsten is not clever and it is not accidental. It is what seventy years of patient state involvement in a dull, dirty, strategically important chemistry looks like. The European Critical Raw Materials Act, the United States Defense Production Act titles on critical minerals, the Japanese JOGMEC stockpile programme, the South Korean strategic materials reserve — each of these is a start. None of them is yet of the scale that would meaningfully move the ratio.
The munitions economy is tungsten-shaped. One of the quieter facts of the current eastern war is that the pace of European 120-millimetre and 155-millimetre ammunition production is bounded by metals the European Union does not control. Steel for cases is abundant. Propellant chemistry has been expanded. Tungsten penetrators and tungsten-carbide tool inserts for machining shell bodies are not. If the war of attrition in eastern Europe lasts another twenty-four months at current intensity, the first visible symptom of the tungsten licence regime will probably be a public argument in Berlin or Brussels about why the shells are being delivered more slowly than announced.
Non-Western supply geography is being quietly rewritten. Masan’s Vietnamese chemistry is being courted. Mongolian deposits are being surveyed by consortia few of which are European. Bolivia’s tin and tungsten belt sits inside a political landscape in which Chinese and Russian industrial relationships have deepened since 2020. The next decade’s tungsten map will include more suppliers. It will not include many Atlantic suppliers.
The quiet shape of the next decade
Take the metal seriously, and the picture becomes concrete.
Western artillery production hits a tungsten ceiling before it hits a steel ceiling. Expect that ceiling to show up in late 2027 or 2028, probably announced as a surprise.
Carbide tool prices rise, and the aerospace supply chain quietly re-prices. The margin on a single wafer of carbide tool-tips is small; the aerospace customer absorbs the cost. The cost passes through to engine prices and ultimately to airline fares, four or five layers removed from the ore body in Jiangxi.
Europe revives Panasqueira, Mittersill, Barruecopardo, La Parrilla, and perhaps the Felbertal expansion in Austria. The combined extra output is useful at the margin and insufficient at the system. The Critical Raw Materials Act numbers are met on paper and not in substance.
Masan becomes politically important. A Vietnamese company with a Thai Nguyên chemistry plant becomes, quietly, one of the two or three most strategically consequential firms in the West’s metals supply chain. Its ownership structure will be courted by Washington, Berlin, Tokyo, and Seoul. Hanoi will manage the courtship with its usual careful ambiguity.
A domestic American tungsten chain is attempted. The Defense Production Act is invoked for one or two projects. Permitting fights follow. The chain, if built, is operational around 2032 at the earliest. By then the industrial geometry will have moved again.
Recycling, stockpile releases, and improvised substitution carry the burden in the interim. The National Defense Stockpile releases tonnage. The Japanese stockpile releases tonnage. European tooling firms expand carbide reclamation. The gap is managed. It is not closed.
The hidden piece, again
The twentieth century understood which materials were strategic. Steel, aluminium, copper, oil, uranium. It stockpiled them, nationalised them, built capacity around them, fought wars over them. The late twentieth and early twenty-first centuries forgot the lesson quickly. The architecture of just-in-time global supply chains assumed that any input you could buy on an invoice was a civilian material. Tungsten sat quietly inside that assumption for a generation.
What the 2024 and 2025 Chinese licence lists make visible is not a new fact but an old one, briefly obscured and now returning: some materials belong to states, whether their nominal owners acknowledge it or not. A commodity that is sold on an invoice is still a strategic reserve if the government that sits over the mine chooses, at any moment, to treat it as one.
A dark metal with a tedious chemistry and no retail glamour decides, in 2026, more about the pace of European rearmament than any speech delivered at a NATO summit. A string of chemistry plants in Jiangxi, Hunan, and Henan sets, invisibly, the rate at which jet engines can be machined in Derby, Munich, and Hartford. The slow steel of eastern wars moves at the speed of a Chinese export desk, and almost no one in the receiving countries is naming the metal.
Element 74. Nineteen point three grams per cubic centimetre. Melts at a star’s surface. Eighty percent out of one country, closing the licence drawer. The next decade of the harder economy — the shells, the drill bits, the shields, the contacts — moves at the pace that a metal nobody argues about chooses, quietly, to allow.
