TSMC Suspends Shipments to Chinese Firm After Chip Found on Huawei Processor
In a significant move reflecting the ongoing tensions between the U.S. and China over technology and national security, Taiwan Semiconductor Manufacturing Company (TSMC) has suspended shipments to Chinese chip designer Sophgo. This decision follows the discovery of a TSMC chip integrated into Huawei’s AI processor, the Ascend 910B, prompting concerns about compliance with U.S. export regulations.
Discovery of the TSMC chip
The situation came to light when tech research firm TechInsights conducted a teardown of Huawei’s Ascend 910B processor and identified a chip produced by TSMC. Sources revealed that TSMC was alerted to the situation about two weeks prior, which led to the immediate suspension of shipments to Sophgo. The latter had reportedly ordered chips from TSMC that were identical to the one found in the Huawei processor. As a result, TSMC notified both Taiwanese and U.S. authorities about the incident, initiating a thorough investigation.
Compliance and Denial by Sophgo
In response to the allegations, Sophgo released a statement asserting that it is in compliance with all applicable laws and regulations and has never engaged in any business dealings with Huawei. The company, which is affiliated with the cryptocurrency mining equipment giant Bitmain, emphasized that it had submitted a comprehensive investigation report to TSMC to demonstrate that it had no ties to Huawei. However, the precise mechanism by which the TSMC chip ended up in a Huawei product remains unclear, raising questions about supply chain transparency and compliance.
Background of the TSMC-Huawei relationship
TSMC, the world’s largest contract chipmaker, has not supplied Huawei with chips since mid-September 2020, following the imposition of stringent U.S. export controls aimed at limiting Huawei’s access to critical technologies. The U.S. government expanded its authority during that period, allowing it to block shipments of foreign-made products that utilize U.S. technology, including chips manufactured by TSMC. The Ascend 910B is regarded as one of the most advanced AI chips produced by a Chinese company, making it a focal point in the broader tech rivalry between the U.S. and China.
Ongoing investigations and reactions
The U.S. Department of Commerce confirmed that it is aware of reports regarding potential violations of U.S. export controls but refrained from commenting on whether any investigations are currently in progress. TSMC, in its statement, mentioned that it has proactively communicated with the Commerce Department about the situation and emphasized that it is not under investigation at this time.
Meanwhile, Huawei reiterated its position, stating that it has not manufactured any chips through TSMC since the enforcement of new U.S. export regulations in 2020. This statement is crucial for Huawei, as it seeks to navigate the complicated landscape of global semiconductor supply and avoid further entanglements with U.S. authorities.

Industry implications and future considerations
The ramifications of this incident extend beyond just TSMC and Sophgo. As companies in the semiconductor industry grapple with the evolving landscape of international trade and export regulations, the need for stringent compliance mechanisms becomes increasingly clear. The semiconductor supply chain is complex, and any lapses in compliance can have serious consequences for businesses involved.
In the context of the ongoing chip war between the U.S. and China, this incident serves as a reminder of the fragile state of global technology supply chains. With geopolitical tensions influencing trade policies and technology access, companies must remain vigilant in ensuring that their operations align with international regulations.
Conclusion
TSMC’s decision to suspend shipments to Sophgo highlights the intricate interplay between technology, national security, and international trade. As the investigation unfolds, the industry will be watching closely to see how this situation develops and what it means for the future of semiconductor manufacturing in both Taiwan and China. The increasing scrutiny on tech companies underscores the importance of transparency and compliance in an era marked by heightened regulatory challenges and geopolitical strife.
