Japan has expressed its opposition to China’s newly imposed export restrictions on dichlorosilane (DCS), a critical chemical in the semiconductor industry, as it evaluates the potential repercussions for Japanese firms. The restrictions mandate that Chinese buyers importing DCS from Japan must provide cash deposits of up to 99.2%. This decision directly impacts Japanese companies such as Shin-Etsu Chemical and Denal Silane.
According to China, these measures are temporary and were enacted following an anti-dumping investigation that concluded Japanese DCS exports were detrimental to China’s local industry. The final ruling on this matter is anticipated upon the completion of the investigation. In response, Japan’s government has urged China to ensure that their actions do not unjustly harm Japanese enterprises and has stated that it will consider suitable measures if required.
This development unfolds against a backdrop of increasingly strained relations between China and Japan, particularly concerning Japan’s stance on Taiwan. Additionally, Beijing has implemented other trade and export limitations affecting Japanese companies, especially concerning dual-use products with potential military applications.
Dichlorosilane plays a vital role in semiconductor manufacturing, as it is used to form ultra-thin silicon layers and other materials on computer chips. Given Japan’s status as a leading global producer of ultrapure DCS, the newly imposed restrictions pose significant implications for the semiconductor supply chain.
