Intriguing Halt: TSMC Ceases Chip Deliveries to Unnamed Client in Huawei Device

Leading chip manufacturer Taiwan Semiconductor Manufacturing Co (TSMC) has halted shipments to one of its customers after discovering that its chips were used in a Huawei product. This move is in response to potential violations of U.S. export restrictions. About two weeks ago, TSMC took action to suspend shipments and launch a thorough investigation into the matter. The issue arose when technology research firm TechInsights disassembled a Huawei product and found a TSMC chip inside. This finding, reported on Tuesday, could signify a breach of U.S. regulations imposed two years ago to limit the capabilities of the Chinese military.

The United States has specifically targeted Huawei in an effort to enforce stricter export controls to prevent Chinese companies from obtaining and producing advanced semiconductors. TSMC has reported the incident to both U.S. and Taiwanese authorities and considers it a significant warning within its operations. The earliest trace of the chip's journey to the Huawei product dates back to October 11.

The identity of the customer for which TSMC has suspended shipments has not been disclosed, and TSMC has declined to comment on the situation. The U.S. had previously restricted the export of advanced AI chips to China, and despite these measures, Chinese entities are reportedly seeking ways to circumvent these restrictions. Earlier this year, it was reported that they were leveraging cloud services from companies like Amazon to access advanced U.S. chips and AI capabilities.

Taiwan, which maintains a cautious stance due to its proximity to China and historical tensions, has implemented its own export controls to prevent the manufacturing of advanced chips in China. Taiwanese authorities have emphasized their commitment to adhering to U.S. export control regulations.
