China's Tungsten Squeeze Exposes Semiconductor Vulnerability - But Spurs the Rise of Alternative Supply Hubs

New Strategic Intelligence Brief from Unravelling Geopolitics Highlights Escalating Geopolitical Risks and Diversification Efforts in Critical Minerals

Tokyo, Japan | June 19, 2026 - Tungsten, with the highest melting point of any pure metal, is essential for producing tungsten hexafluoride (WF6) gas used in depositing ultra-thin interconnect layers in advanced integrated circuits. China dominates global tungsten production (approximately 82-83% in recent years) and refining capacity.

Beijing's February 2025 export restrictions on tungsten products - part of a pattern seen with gallium, germanium, and other critical materials - are not only creating short-term shortages and price surges but also positioning Chinese firms to capture more value in processed semiconductor-grade materials.

These export controls have already disrupted Japanese suppliers Kanto Denka and Central Glass, forcing them to halt WF6 production from July 1, 2026, and impacting clients including TSMC, Samsung, and SK Hynix.

So, Unravelling Geopolitics today released a comprehensive strategic intelligence brief examining how China's tightening grip on tungsten exports is reshaping global semiconductor supply chains and accelerating urgent diversification efforts by the United States and its allies, including major chip manufacturers like South Korea.

"China's export controls on tungsten underscore a fundamental shift in global trade: resilience is now as critical as efficiency, and supply chain decisions are going to be increasingly driven by geopolitical reliability rather than cost alone," said Tanmay Kadam, author of the brief and geopolitical observer. "While these measures create short-term disruptions for the semiconductor industry, they are simultaneously catalyzing investment in alternative sources that could reshape supply chain dynamics for years to come."
