- China's commerce ministry imposed anti-dumping measures on Japanese dichlorosilane (DCS) imports, requiring companies to post cash deposits of up to 99.2% starting Tuesday and targeting exporters including Shin-Etsu Chemical and Denal Silane.
- Japan formally protested the curbs; Chief Cabinet Secretary Minoru Kihara said Tokyo would "respond appropriately" to prevent unfair harm to Japanese companies.
- Beijing framed the move as a provisional anti-dumping action stemming from an investigation into Japanese DCS exports that allegedly damaged domestic industry, with a final ruling still pending.
- China has separately imposed export controls on Japanese firms over dual-use items with military applications, part of a broader economic pressure campaign against Tokyo.
- Japan-China relations have been strained since November, when Prime Minister Sanae Takaichi suggested Japan's military could intervene if China used force on Taiwan, a self-ruled island Beijing claims.
- Dichlorosilane is used in chemical vapor deposition to deposit thin silicon and oxide films in semiconductor logic and memory chips, and Japan is the global leader in producing ultrapure DCS for chip fabrication.
Why it matters: Japan dominates ultrapure DCS supply for advanced chip fabrication, so a 99.2% cash deposit requirement effectively prices Japanese exports out of the Chinese market. Beijing's anti-dumping framing sits alongside separate dual-use export controls on Japanese firms, signaling a coordinated economic retaliation campaign that began after PM Takaichi's November Taiwan comments.
