China Launches Anti-Dumping Probe Into Key Japanese Chipmaking Chemical

China has opened an anti-dumping investigation into a vital chemical imported from Japan. The move escalates trade tensions between the two nations. The probe targets dichlorosilane. This chemical is essential for semiconductor manufacturing. It is used in a process called thin-film deposition to produce various types of chips. China's Ministry of Commerce announced the investigation. It will last for one year but could be extended by another six months. Anti-dumping measures are trade tools. A country uses them when it believes another nation is selling goods below fair market value. This can hurt domestic industries. The investigation focuses on a material critical to the global technology supply chain. Semiconductors, or chips, are vital components in everything from smartphones to cars.
