The U.S. government tightened its control over exports of advanced computing and semiconductor manufacturing products to China on October 17th. The Entity List now includes more Chinese companies, including two prominent Chinese GPU manufacturers, Biren Technology and Moore Threads. These new restrictions further limit the export of Nvidia A800 and H800 chips.

The new regulations also block chips transferring to China through third-party countries, broadening the export restrictions to include Chinese overseas subsidiaries companies and additional 21 countries.

As reported from TechNews, Nomura Securities are unsurprising to Biren Technology and Moore Threads’ addition to the Entity List. These two chip makers primarily rely on TSMC as their main partner. Due to their limited production capacity, the influence on TSMC is anticipated to be minimal.

Since the U.S. initiated export controls on AI chips in October last year, operations of Biren Technology have continuously been affected. This new development is anticipated to have a relatively limited impact on the Chinese IC design market.

However, the import of ASML’s 1980i DUV model into China may be restricted without U.S. approval. Nomura Securities believe that this could negatively affect the Chinese semiconductor market, potentially causing delays in the expansion plans for 28nm production capacity for some Chinese semiconductor companies. These companies will also likely continue to postpone the purchase of domestic equipment.

Since the import of Nvidia A800, H800, and L40S into China might not be allowed, Nomura Securities consider this unfavorable news for the market. Nvidia may soon introduce new versions to comply with the new regulations. In this scenario, Huawei, with its capacity to design and manufacture advanced chips within China, may ultimately emerge as the most significant beneficiary in the Chinese market, as most Chinese GPU companies are already under sanctions.

The updated U.S. export restrictions also imply that more foreign manufacturers of AI chips will need to adjust their product specifications to meet the new requirements.
