Japan protests China's 99.2% import duty on key chip chemical

Japan has lodged a protest with China over new import duties on dichlorosilane, a crucial chemical for semiconductor manufacturing. China has imposed these duties, citing violations of anti-dumping regulations and harm to its domestic industry, with rates reaching up to 99.2% for Japanese exporters like Shin-Etsu Chemical and Denal Silane. This move exacerbates existing trade tensions between the two nations, particularly concerning Taiwan. AI

IMPACT Disrupts supply chains for semiconductor manufacturing, potentially increasing costs and affecting global chip production.
