Japan has formally objected to China’s recent decision to implement stringent restrictions on the export of dichlorosilane (DCS), a critical chemical used in the semiconductor industry. The new measures require that Chinese importers of DCS from Japan make cash deposits of up to 99.2%, a move that could significantly impact Japanese companies like Shin-Etsu Chemical and Denal Silane. As Japan evaluates the potential repercussions for its businesses, the government has expressed concerns about the implications of these restrictions.
According to Chinese authorities, the restrictions are temporary and follow an anti-dumping investigation which purportedly revealed that Japanese exports of DCS have adversely affected China’s local industry. The investigation is ongoing, and a final decision on the matter will be reached once it is concluded. In response, the Japanese government has called on China to ensure that any measures taken do not disproportionately harm Japanese businesses and has stated its readiness to take appropriate actions if required.
This development unfolds against a backdrop of escalating tensions between China and Japan, with relations strained over Japan’s stance on Taiwan. In recent times, Beijing has also rolled out other trade and export limitations targeting Japanese companies, particularly those involved with dual-use products that could be employed for military purposes. These actions have further complicated the diplomatic landscape between the two nations.
Dichlorosilane is integral to semiconductor manufacturing, utilized to form ultra-thin layers of silicon and other materials on computer chips. Given Japan’s status as a major global producer of ultrapure DCS, China’s restrictive measures bear significant consequences for the semiconductor supply chain, potentially disrupting global production processes.
