Specialty Network SLLC – The Biden administration is ramping up its efforts to curb China’s technological advancements by blacklisting Huawei and Sophgo. This Chinese company has been accused of illegally incorporating a Taiwan Semiconductor Manufacturing Company (TSMC) chip into Huawei’s AI processor, sparking a new wave of tensions in the U.S.-China tech rivalry. The move has significant implications for global technology, trade, and the semiconductor supply chain.

Sophgo came under scrutiny after a research firm, TechInsights, dismantled Huawei’s Ascend 910B processor and found a TSMC-manufactured chip inside. This chip matched a design previously ordered by Sophgo, raising suspicions about how it ended up in Huawei’s AI processor.
U.S. laws prohibit foreign-made chips with U.S. technology from being sold to Huawei without a license, a rule introduced in 2020 to block the company from acquiring critical tech components. Sophgo is alleged to have bypassed these restrictions, making it a key player in what officials describe as Huawei’s “shadow network.”
The Entity List, a trade blacklist maintained by the U.S. Department of Commerce, imposes strict restrictions on companies that are added to it. Sophgo’s inclusion means:
This development also further isolates Huawei, which has struggled under similar restrictions since being blacklisted in 2019.
Taiwan Semiconductor Manufacturing Company, the world’s leading contract chipmaker, has faced immense scrutiny following the discovery of its chip in Huawei’s processor. Upon being notified by TechInsights, TSMC immediately suspended shipments to Sophgo.
The company clarified that it has not supplied Huawei since 2020, adhering strictly to U.S. export controls. However, this incident highlights the challenges semiconductor manufacturers face in ensuring their products are not misused or redirected.
Huawei, once a leader in global telecommunications, faces yet another setback. The blacklisting of Sophgo cuts off another potential avenue for sourcing critical components. This move increases the pressure on Huawei as it continues to grapple with the U.S.’s aggressive sanctions.
China has been working to achieve self-reliance in semiconductors, but moves like this highlight how reliant it still is on foreign suppliers like TSMC. The blacklisting of companies like Sophgo underscores the difficulties China faces in developing a truly independent tech ecosystem.
The global semiconductor industry, already strained by geopolitical tensions and supply chain disruptions, faces further uncertainty. Companies like TSMC must navigate complex regulatory requirements while balancing relationships with clients across different geopolitical spheres.

Sophgo’s blacklisting is another chapter in the escalating tech war between the U.S. and China. The Biden administration has made it clear that any attempt to bypass restrictions on Huawei will have severe consequences.
For China, these moves are perceived as deliberate attempts to stifle its technological growth. For the U.S., targeting firms like Sophgo is seen as a necessary step to protect national security and maintain its lead in critical technologies.
The blacklisting of Sophgo not only impacts Huawei but also signals a broader effort by the U.S. to control the flow of advanced technologies. As the U.S.-China tech war continues, the stakes for global technology and trade are higher than ever.
This incident underscores the challenges of maintaining compliance in a fragmented global supply chain and highlights the increasing polarization of the tech industry. Companies, governments, and stakeholders worldwide must now navigate this new landscape with caution and strategy.
