China’s Unprecedented Tungsten Export Freeze to Japan Triggers a Global Scramble

For the first time since China began publishing disaggregated trade statistics in 2015, it exported zero carbonized tungsten or tungsten powder to Japan—a freeze that lasted from February through April 2026 . The policy did not emerge in isolation. It capped a year-long tightening of Chinese mineral export controls and was triggered directly by a geopolitical flashpoint: Japanese Prime Minister Takako Suga’s public remarks on a "Taiwan contingency"—the idea that an attack on Taiwan could constitute an existential threat to Japan .

The Trigger: Dual-Use Export Controls as a Geopolitical Lever

China’s Ministry of Commerce acted on two specific dates. On January 6, 2026, Announcement No. 1 of 2026 tightened export controls on "military-civilian dual-use items" destined for Japan . On February 24, China added 20 Japanese companies to its export control list and banned exports of dual-use products to those entities .

Analysts at the Center for Strategic and International Studies assessed the move as a direct response to Suga’s Taiwan comments, noting that this iteration of controls ties export restrictions directly to a security dispute rather than a conventional trade disagreement . The tungsten products hit by the ban—especially tungsten carbide and tungsten powder—are irreplaceable inputs for Japan’s machine-tool, automotive, and precision-engineering sectors, where they are used in cutting tools and wear-resistant components .

This targeted escalation sat atop broader tungsten export controls that Beijing had already imposed in February 2025, when it moved tungsten, tellurium, bismuth, molybdenum, and indium onto a license-based export regime that replaced older quota management . Those earlier controls had already caused Chinese ammonium paratungstate (APT) exports to collapse by nearly 70%, from 782 tonnes in 2024 to 243 tonnes in the first 11 months of 2025 .

Japan's Playbook: Diversification, Recycling, and Alliances

Japan’s response drew directly on its experience during the 2010 rare-earth embargo, when a Chinese cutoff caused a tenfold price spike and forced an overhaul of critical-material sourcing .

Sumitomo Electric Industries, one of Japan’s largest industrial conglomerates, announced it would fully halt tungsten raw-material procurement from China, replacing it with imports from the United States and a major push into scrap-tungsten recycling . Japanese corporations are securing scrap tungsten from both the U.S. and Europe and expanding recycling facilities that recover tungsten from end-of-life cutting tools .

At the policy level, Japan is deepening cooperation with both the EU and the U.S. The centerpiece is the proposed EU-Japan Critical Raw Materials Alliance, which would pool financial resources, coordinate stockpiling, and provide purchase guarantees and concessionary loans for joint diversification projects .

The EU's Countermove: A First-of-Its-Kind Strategic Stockpile

The European Union has moved on a parallel track. In May 2026, the EU shortlisted tungsten, rare earths, and gallium for its first-ever coordinated critical-minerals stockpile, a project designed to reduce dependency on China for materials essential to defense, semiconductors, and the energy transition . EU officials are in talks with major ports—including Rotterdam, Europe’s largest—to host the storage facilities .

The stockpile plan has a policy backbone. In February 2026, the EU, U.S., and Japan signed a joint commitment to "identify areas of cooperation to stimulate demand and diversify supply," pledging to back mining, refining, and recycling projects outside China and to share stockpiling information . The European Commission has also signaled plans for a joint purchasing and strategic stockpiling center for critical raw materials, inspired explicitly by the Japanese model .

Price Shock: How the Market Absorbed the Cutoff

The consequences for prices have been extreme. China produces more than 80% of the world's tungsten and accounts for roughly 80% of global APT supply . In 2025, Beijing cut its domestic mining quota by 6.5%, from 62,000 tonnes to 58,000 tonnes, while export volumes plunged .

European APT prices reached $430 per metric tonne unit (mtu) by June 18, 2025, a 30.3% increase from the start of the year . By September 2025, prices had climbed to $580–$650/mtu, an 86.4% year-to-date rise . Chinese domestic tungsten product prices surged more than 200% in 2025, driven by the combination of export controls, reduced mining quotas, and increased military demand .

By April 2026, prices had broken further into record territory, with supply described as "stretched thin" . A May 2026 analysis from the Swedish Institute for International Affairs confirmed that China’s mineral export restrictions have caused "substantial temporary falls in export volumes" and "sharp price increases" across multiple critical minerals, with some reductions proving permanent .

The freeze is not an isolated incident. It follows a pattern China established as early as 2011, when it banned rare-earth exports to Japan after a maritime territorial dispute, and reinforces an era in which critical minerals function as instruments of geopolitical pressure . For Japan and the EU, the current scramble to diversify and stockpile is an acknowledgment that supply chains built on a single dominant producer are no longer viable in an increasingly weaponized trade landscape.
