The Shipment Data Already Turned

This is not a forward-looking warning - the volume has already moved. Chinese customs (GACC) data shows China's tungsten APT exports to Japan fell 70% year-over-year, from 782 tonnes in 2024 to 243 tonnes across January-November 2025. Tungsten prices have hit a 12-year high on the back of it.

The policy behind the numbers: China's 2026 Dual-Use Items Catalogue now lists tungsten, ammonium paratungstate (APT), tungsten oxide, and tungsten carbide under export licensing. What was a freely traded input is now a permission-gated one.

Why This Reaches Your Silicon

Tungsten is not an abstract metal-market story - it is a semiconductor input. It threatens the tungsten hexafluoride (WF6) gas that 3nm-7nm process nodes depend on for metallization. A licensing regime upstream of WF6 flows downstream as constrained wafer output and higher device costs across the most advanced nodes - the same nodes AI accelerators are already fighting over.

Defense demand compounds the squeeze. Estimated at roughly 12% of the tungsten market today, it is expected to grow toward 15% between 2027 and 2028, competing directly with commercial semiconductor and tooling demand for a supply that is now politically rationed.

The Western Answer Arrives Too Late for 2026

There is a genuine Western critical-minerals push underway - it just will not move a part to your warehouse this quarter:

  • USA Rare Earth finalized $1.6B CHIPS Act funding with the Commerce Department, plus $1.5B in private capital.
  • South32's $2.16B Hermosa project in Arizona won board approval and a $166M DOE grant - the only advanced US mine producing two federally designated critical minerals (zinc and manganese).
  • The DoD took a base lease at Tooele Depot for dysprosium/terbium refining via REalloys.
  • Teck Resources received $400M from the Canada Growth Fund to double germanium and antimony output.

That is roughly $4.3B in government-backed commitment - but pilot processing does not begin until late 2026, and commercial scaling lands in 2027-2028. For this year's builds, restricted access is the planning assumption.

What Buyers Should Do Now

  1. Next 48 hours: Scrub BOMs and Approved Vendor Lists for programs exposed to advanced-node (3nm-7nm) silicon and to China-restricted tungsten, antimony, gallium, and germanium. Ask your silicon suppliers directly about WF6 gas coverage.
  2. Next 30 days: Fast-track alternate channel and material qualification with your contract manufacturers - alternates must clear the same reliability gates before volume release, so start now.
  3. Next 90 days: Assume restricted critical-mineral access persists into 2027-2028 and build it into cost models and multi-year supply agreements. Do not price Western supply into 2026 plans.
