Japan has lodged a formal protest against China’s recent move to impose stringent export restrictions on dichlorosilane (DCS), a critical chemical in semiconductor production. The Japanese government is currently evaluating the potential repercussions of these measures on its companies, including prominent exporters such as Shin-Etsu Chemical and Denal Silane.
The newly introduced regulations demand that Chinese importers of Japanese DCS provide cash deposits of up to 99.2%, which could significantly affect trade dynamics. China’s rationale for these provisional measures stems from an anti-dumping investigation that concluded Japanese DCS exports have adversely impacted its domestic industry. A definitive resolution is anticipated once the investigation is finalized.
In response, Japan has called on China to prevent any unjust detriment to Japanese enterprises and has indicated readiness to implement suitable countermeasures if deemed necessary. This development is set against a backdrop of escalating tensions between China and Japan, partly due to Japan’s stance regarding Taiwan. Furthermore, Beijing has enacted additional trade and export restrictions targeting Japanese companies, especially concerning dual-use items with potential military applications.
Dichlorosilane plays a pivotal role in semiconductor manufacturing, specifically for forming ultra-thin layers of silicon and other materials on microchips. Given Japan’s status as a leading global supplier of ultrapure DCS, these restrictions could have significant implications for the semiconductor supply chain worldwide.
