Industry China tungsten curbs disrupt WF6 supplies, raising risks for HBM and AI chip output AI Summary The push to expand AI semiconductor output is straining supply chains for specialty electronic gases, an analysis said. China’s controls on high-purity tungsten exports have led to disruptions in Japan’s supply of tungsten hexafluoride (WF6), raising new supply-chain risks for high-bandwidth me

Global expansion in AI chips, advanced logic processes, and multilayer 3D NAND flash memory is driving demand for tungsten hexafluoride (WF6), a critical electronic specialty gas used in semiconductor manufacturing. Limited short-term supply additions and low industry inventories are widening the supply-demand gap, triggering a rapid price increase.

The semiconductor supply chain is facing another raw material shock — this time from tungsten hexafluoride, or WF6, a specialty gas used in chip manufacturing. Planned production adjustments or exits by some Japanese suppliers in the second half of 2026 have intensified concerns over tighter global supply, sending prices sharply higher and raising the risk of disruption into 2027.
