According to Reuters, the U.S. Department of Commerce has officially mandated Taiwan Semiconductor Manufacturing Company (TSMC) to cease all deliveries of advanced semiconductor chips to Chinese clients immediately. This directive specifically targets semiconductors with 7-nanometer or more sophisticated architectures designed for artificial intelligence applications and graphics processing units (GPUs).

This order took effect on Monday, following an earlier incident where research firm Tech Insights identified components manufactured by TSMC within Huawei's hardware, specifically in their artificial intelligence processors. Upon discovery, TSMC promptly halted the shipment of the implicated chips.

Under the directive from the U.S. Department of Commerce, TSMC swiftly responded by informing all affected Chinese customers, including chip design firms, that starting November 11, they would discontinue the supply of chips utilizing 7-nanometer or more advanced technologies intended for artificial intelligence and GPU applications. Among the impacted companies is Xinluo Technology, which discovered that its chip products matched the restrictions associated with Huawei's Ascend 910B AI processor.

However, despite stringent export restrictions, the trade of artificial intelligence chips appears to persist. Reports indicate that in the Shenzhen region, several suppliers continue to engage in chip transactions exceeding $100 million. Additionally, it has been recently revealed that an Indian pharmaceutical company has sold high-performance servers equipped with Nvidia chips to Russia, with deal values surpassing $300 million.

In response to these developments, the Biden administration is proactively seeking to revise technology export regulations to China, with plans to place approximately 120 Chinese companies on the Department of Commerce's restricted entities list. This move aims to further tighten restrictions and oversight on China's technological advancements.

The U.S. Department of Commerce's directive is poised to have significant repercussions on the global semiconductor market, particularly within China's artificial intelligence and GPU sectors. As one of the world's foremost chip manufacturers, TSMC's supply disruption poses substantial challenges to China's related industries. Looking ahead, technological competition and trade disputes between the U.S. and China are likely to escalate, presenting the global technology industry with an increasingly complex and volatile landscape.
