China’s Tungsten Tap Runs Dry for Japan—And the World Scrambles

From Words to Weaponization: The Policy Timeline

China’s Ministry of Commerce tightened the noose in two swift moves. On January 6, 2026, Announcement No. 1 clamped down on exports of "military-civilian dual-use items" bound for Japan . Then on February 24, Beijing added 20 Japanese companies explicitly to its export control blacklist, prohibiting dual-use shipments to them outright .

Analysts at the Center for Strategic and International Studies (CSIS) wasted no time connecting the dots, calling the move a clear retaliation for Suga's remarks rather than a conventional trade dispute. This wasn't about tariffs; it was about security—and using resources as leverage .

The tungsten products caught in the crossfire—particularly tungsten carbide and tungsten powder—aren't optional extras. They are the backbone of Japan's machine-tool, automotive, and precision-engineering industries, essential for the cutting tools and wear-resistant components that keep assembly lines moving .

This surgical strike sat atop a broader tightening that Beijing had already set in motion a year earlier. In February 2025, China shifted tungsten, tellurium, bismuth, molybdenum, and indium from old-school quota management to a restrictive license-based export regime . The immediate result was a near-collapse in Chinese ammonium paratungstate (APT) exports—down almost 70% from 782 tonnes in 2024 to just 243 tonnes through the first 11 months of 2025 .

Japan's Battle Plan: Recycle, Diversify, Ally

For Japan, this wasn't its first rodeo. The 2010 rare-earth embargo, when China cut off shipments over a maritime spat, had already taught Tokyo a brutal lesson. That cutoff sent prices soaring tenfold and forced a national reckoning on critical-material sourcing .

This time, Japan moved faster. Sumitomo Electric Industries, one of the nation's industrial titans, declared it would stop buying Chinese tungsten raw materials altogether. Instead, the company is sourcing from the United States and making a massive push into scrap-tungsten recycling—recovering the metal from end-of-life cutting tools rather than relying on fresh ore .

This recycling drive doesn't stop at Japan's borders. Japanese firms are securing scrap tungsten from both the U.S. and Europe, while simultaneously expanding domestic facilities to process it .

On the diplomatic front, Tokyo is building a coalition. The centerpiece is the proposed EU-Japan Critical Raw Materials Alliance, a framework to pool financial firepower, coordinate stockpiling, and offer purchase guarantees and concessionary loans for joint diversification projects .

Brussels Builds a Buffer: The EU's First Strategic Stockpile

The European Union—equally dependent on Chinese minerals for its defense, semiconductor, and green-energy ambitions—isn't waiting on the sidelines. In May 2026, the EU shortlisted tungsten, rare earths, and gallium for its first-ever coordinated critical-minerals reserve, with the explicit goal of reducing reliance on Beijing .

Discussions are already underway with major European ports, including Rotterdam, the continent's largest, to host the storage facilities .

This plan has teeth. In February 2026, the EU, U.S., and Japan signed a joint pledge to "identify areas of cooperation to stimulate demand and diversify supply"—a commitment to back mining, refining, and recycling projects outside China and to share information on stockpiling . The European Commission, taking a page from Tokyo's playbook, has signaled its intent to create a joint purchasing and strategic stockpiling center for critical raw materials modeled explicitly on the Japanese system .

The Price Shock: A Market Unhinged

When the world's dominant supplier turns off the tap, the numbers get ugly fast. China controls more than 80% of global tungsten production and roughly 80% of APT supply . In 2025, Beijing cut its domestic mining quota by 6.5%, from 62,000 to 58,000 tonnes, even as export volumes cratered .

The European market felt it immediately. APT prices in Europe hit $430 per metric tonne unit (mtu) by June 18, 2025—a 30.3% jump since January . By September, the range had surged to $580–$650/mtu, an 86.4% year-to-date spike . And inside China, domestic tungsten product prices skyrocketed more than 200% in 2025 alone, fueled by the triple squeeze of export controls, reduced mining quotas, and soaring military demand .

By April 2026, even before the full scale of the Japan freeze was absorbed, prices were in uncharted territory. Supply was described as "stretched thin" . A May 2026 analysis from the Swedish Institute for International Affairs confirmed the pattern: China's mineral restrictions have triggered "substantial temporary falls in export volumes" and "sharp price increases," with some supply reductions now looking permanent .

A New Normal of Resource Weaponization

This isn't an isolated shock. It follows a playbook China dusted off as early as 2011, when it banned rare-earth exports to Japan following a dispute over the Senkaku Islands .

For Japan, the EU, and the U.S., the current scramble—diversifying suppliers, stockpiling, and supercharging recycling—reflects a hard truth: supply chains anchored to a single dominant producer are no longer a commercial risk but a national security liability. The age of critical minerals as geopolitical chess pieces has arrived, and the West is scrambling to catch up.
