Japan has expressed strong opposition to China’s newly imposed restrictions on the export of dichlorosilane (DCS), a critical chemical in semiconductor production. The Japanese government is currently evaluating how these measures might affect its companies, notably Shin-Etsu Chemical and Denal Silane, which are key exporters of DCS. Under the new rules, Chinese importers are required to pay cash deposits as high as 99.2% for DCS imports from Japan.
China has labeled these restrictions as temporary, stating they stem from findings of an anti-dumping investigation that suggested Japanese DCS exports have adversely impacted China’s domestic industry. A definitive conclusion is expected once the investigation is finalized. In response, Japan has urged China to prevent any undue harm to Japanese business interests and has signaled readiness to take necessary actions if required.
This development unfolds amid escalating tensions between China and Japan, partly due to Japan’s stance on Taiwan. The friction has led China to implement additional trade and export limitations on Japanese entities, especially concerning dual-use products that could be leveraged for military purposes.
DCS plays a vital role in the semiconductor industry, primarily for creating ultra-thin silicon layers on computer chips. Given Japan’s status as a leading global supplier of ultrapure DCS, these new export restrictions pose significant implications for the semiconductor supply chain, potentially impacting global production and distribution.
