The ongoing geopolitical tensions between the United States and China have now taken a significant turn with the Biden administration’s recent announcement of an investigation into legacy semiconductors produced in China. By focusing on this critical component of the technology supply chain, the U.S. government aims to reassess its dependence on Chinese-manufactured chips, which play a vital role in a variety of sectors ranging from consumer electronics to national defense.
The importance of semiconductors in modern technology cannot be overstated. From smartphones to advanced military systems, these chips form the backbone of virtually every electronic device. In its official statement, the White House articulated concerns that China employs “non-market policies and practices” to secure its position in the semiconductor industry. This includes outright industrial targeting that not only undermines competition but also creates risky dependencies in foundational technologies. By launching the Section 301 investigation, U.S. officials aim to analyze China’s practices—including the production of silicon carbide substrates—that are integral to semiconductor manufacturing.
Understanding the distinction between legacy chips and cutting-edge alternatives is crucial. While manufacturers such as Taiwan Semiconductor Manufacturing Company (TSMC) are at the forefront of advanced chip production, Chinese firms have managed to develop their legacy chips at scale, despite being generations behind. Legacy chips may not have the sophistication of modern counterparts, but their widespread usage in essential applications—like telecommunications and the electrical grid—means they are far from obsolete. This reality poses a challenge for U.S. policymakers who see the need to both secure the supply chain and diminish reliance on potential adversaries.
The investigation, grounded in the Trade Act of 1974, opens the door to various remedial measures. One potential action includes the imposition of tariffs on Chinese legacy chips, which could significantly impact manufacturers and consumers alike. Given the Biden administration’s ongoing efforts to exert pressure on China’s tech sector—evidenced by increased tariffs this year—the discovery of unfair practices may further strengthen these restrictions. However, any decision made will have to carefully weigh the repercussions on American industries that depend on inexpensive semiconductor inputs.
As the investigation unfolds, it remains uncertain how the outcomes might intersect with the incoming administration of Donald Trump. Notably, the Biden administration has announced an intention to transfer the probe to Trump’s team, indicating that this high-stakes issue will continue to dominate discussions on economic policy and international relations. In a climate where technology races forward while geopolitical tensions simmer, the broader implications of such investigations could shape the future of U.S.-China relations and the global tech landscape for years to come.
The Biden administration’s investigation into Chinese legacy semiconductors is not merely a regulatory action but rather a strategic maneuver to address a complex web of economic dependencies and competitive practices. As we proceed into a new political era, the ramifications of this inquiry will not only define the trajectory of U.S.-China relations but also set the stage for the future of the global semiconductor landscape, potentially reshaping industries and economies worldwide.
