China’s Tungsten Licensing Tightens the Materials Squeeze

China’s tighter tungsten export licensing is adding an upstream materials bottleneck to an already strained semiconductor supply chain, raising sourcing risk for fabs and toolmakers worldwide.

• •China now licenses tungsten oxide, carbide, and related exports through a small approved exporter set.
• •Materials controls add a new chokepoint on top of U.S. limits on tools, service, and chip purchases.
• •The result is a deeper two-tier market: domestic substitution in China, de-risked capacity outside it.
• •Operators must secure materials resilience, not just equipment and service continuity.
• •Value is shifting to vendors that can localize for China while protecting advanced capacity elsewhere.
