Overseas inventory only supports until the end of June, domestic tungsten hexafluoride welcomes a "golden window".

Due to multiple factors such as the tightening of overseas supply chains and a surge in downstream demand, the supply-demand gap continues to widen, leading to a significant increase in the price of tungsten hexafluoride. According to monitoring by the Buychem Plastics Research Institute, as of now, the price of 99.999% purity tungsten hexafluoride in China is between 1670-1810 yuan/kg, with a price increase of 232.7% compared to the same period last year. Core suppliers such as SK Specialty and Foosung from South Korea have officially notified chip giants such as Samsung Electronics and SK Hynix that they will significantly raise the price of tungsten hexafluoride in 2026, with the increase expected to be as high as 70% to 90%. In addition, companies like Kanto Denka and Central Glass from Japan have informed semiconductor customers in South Korea such as Samsung that their stock can only last until the end of May to the end of June, and that the supply in the second half of the year cannot be guaranteed, suggesting that they seek other suppliers.
