TSMC warns of limits of ability to keep its AI chips from China

Key Points

  • TSMC faces challenges in ensuring export control compliance due to limited visibility in the downstream use of its semiconductors.
  • The company has acknowledged the difficulty in preventing unintended end-uses and diverted shipments by intermediaries.
  • TSMC has been cooperating with authorities after discovering that its chips might have been diverted to restricted entities like Huawei.

Summary

Taiwan Semiconductor Manufacturing Co. (TSMC) has highlighted significant challenges in maintaining compliance with export controls, particularly after its AI silicon was found in products of US-sanctioned Huawei Technologies Co. via intermediaries. In its latest annual report, TSMC noted that its position in the semiconductor supply chain restricts its ability to monitor the final use or users of its products, complicating efforts to prevent misuse or unauthorized diversions. Despite its efforts to comply with export regulations, TSMC admits there is "no assurance" against compliance issues. The company has been working with authorities following an incident where its chips were potentially diverted to Huawei, which led to a halt in shipments to a client. This situation underscores the broader geopolitical tensions, with the US implementing new regulations to restrict China's access to advanced AI chips, and blacklisting companies involved in such diversions.
