US Considers Revoking Chipmaker Authorizations in China Amid Trade Tensions

The U.S. Department of Commerce is reportedly weighing the revocation of special authorizations granted to global chipmakers Samsung, SK Hynix, and TSMC, potentially limiting their access to American chipmaking equipment and technology in China. This move, still under consideration, could complicate semiconductor manufacturing for these firms in China, where they supply chips for various industries.

Following a 2022 crackdown on semiconductor exports to China, the U.S. granted temporary authorizations and later issued Validated End User (VEU) status to these companies, enabling streamlined access to U.S.-made technology without repeated licensing. The possible revocation of these privileges would align these companies with stricter export controls already imposed on Chinese semiconductor firms.

A White House official emphasized that the Trump administration currently has no intention of implementing the restrictions but wants the option available if U.S.-China trade relations deteriorate. “It’s another tool in our toolbox,” the official said, suggesting preparations for a potential breakdown in agreements over rare earth exports and semiconductor cooperation.

Shares of U.S. chip equipment suppliers, including KLA Corp, Lam Research, and Applied Materials, dropped following reports of the move. Meanwhile, shares of Micron Technology, a competitor in the memory chip sector, rose by 1.5%.

Industry analysts warn that curbing equipment exports to foreign chipmakers in China could inadvertently benefit Chinese semiconductor firms by reducing competition. While TSMC declined to comment, Samsung, SK Hynix, and U.S. suppliers have yet to respond.

The Commerce Department stated that any changes would maintain fair competition and ensure reciprocal trade enforcement. VEU status allows foreign firms to receive U.S. technology under strict conditions, including compliance with equipment restrictions and reporting rules.

This potential policy shift could reshape global semiconductor supply chains and impact the tech industry’s competitive landscape.
