China Chokehold Sends Tungsten Soaring

Tungsten prices hit records as China’s export controls and tight mine quotas squeeze the world’s supply chain, raising costs for chips, tools, and defense parts.

What Changed: China’s Rules Reshape a Critical Metal

China announced export controls on items tied to tungsten in early February 2025, shifting shipments to a license model and tightening oversight at the border. Reuters reported the rule covers multiple tungsten product types and their manufacturing processes, which means more chokepoints in the chain from ore to chemicals to powders. This was part of a wider series of mineral controls since 2023, as Beijing linked resource policy to trade and national security goals. Buyers worldwide began to face slower approvals and smaller lots.

China dominates global tungsten processing and chemical output, including ammonium paratungstate, a key feedstock for hardmetals and specialty gases. When exports need licenses, traders, toolmakers, and chip‑adjacent firms cannot rely on steady weekly flows. Officials also cut domestic mining quotas in 2025, which tightened the upstream balance inside China and reduced available material for export. Together, these moves made every step costlier and riskier for buyers outside China, from cutting tools to electronics.

Why Prices Spiked: Thinner Supply Meets Steady Demand

By April 2026, tungsten prices pushed to record highs. Market reports tied the surge to China’s tighter export rules, firm military demand, and scarce new mines elsewhere. In December 2025, Beijing said only 15 companies could export tungsten during 2026–2027, shrinking the number of channels for the world’s largest supplier. Some Japanese producers warned of shortages for tungsten hexafluoride, a gas used in chipmaking steps, due to depleted inventories after the controls took hold. Each link felt the strain.

Industry delegates and producers outside China described a clear shift: China’s strong appetite for concentrates at home, plus export limits on key products like ammonium paratungstate, left the rest of the world short and drove prices higher. This pattern fits past critical‑minerals shocks, where a concentrated supplier tightens controls and downstream users scramble to adjust. While artificial intelligence projects lifted interest in chip supply chains, the best‑documented squeeze sits in policy and capacity, not a single demand boom.

Who Feels It: Toolmakers, Chip Supply, and Defense Buyers

Cutting tools, drill bits, and wear parts rely on tungsten carbide for hardness and heat resistance. When feedstock costs jump, factories pay more and pass costs to builders, mechanics, and small shops. Chip supply chains also use tungsten in films and vias, and some steps need tungsten hexafluoride. Reports from Asia flagged the risk of curtailed output if inputs stay tight. Defense buyers face higher bills too, since tungsten goes into armor‑piercing rounds and parts that must endure extreme heat and stress.

Supply shortage evidence

A major tungsten carbide facility in Ontario, Canada reportedly shut down earlier this year because of tungsten shortages, illustrating that the supply squeeze is already affecting downstream manufacturers.

Households see the effect as slower deliveries, pricier repairs, and higher costs for gear that uses precision tools. Small manufacturers carry the heaviest load because they lack the cash to stockpile. This fuels a wider worry shared by both left and right: a few players can throttle key inputs, while Washington argues and agencies stall projects. People see the same cycle—more rules, more red tape, and no clear plan to build mines, refineries, and recycling at home at the speed industry needs.

What Comes Next: Diversify, Substitute, or Pay More

Companies are racing to diversify supply, but new mines take years, face permit fights, and need big cash up front. Producers outside China are trying to lift output of ammonium paratungstate and carbides, yet scaling is slow and costly. Without faster permits and clearer rules, the United States and allies will likely pay more and remain exposed. China, for its part, defends its controls as lawful steps to protect resources and security, and urges others to respect market rules. That stance has not eased shortages.
