The U.S. Department of Commerce is considering revoking authorizations granted in recent years to major chipmakers Samsung, SK Hynix, and TSMC that allow them to receive U.S. goods and technology at their manufacturing plants in China, sources familiar with the matter said. This potential move would complicate operations for these foreign semiconductor firms in China, where they produce chips used across many industries.
While the likelihood of the U.S. actually withdrawing these authorizations remains uncertain, officials view the tactic as a contingency if the current trade truce between the U.S. and China deteriorates. A White House official emphasized that the U.S. is “just laying the groundwork” and expressed confidence the trade agreement would continue, including the agreed supply of rare earth minerals from China. The official clarified that “there is currently no intention of deploying this tactic,” but it remains a tool in case bilateral relations worsen.
Following early reports, shares of U.S. semiconductor equipment suppliers that serve Chinese plants dropped: KLA Corp fell 2.4%, Lam Research declined 1.9%, and Applied Materials sank 2%. Conversely, shares of Micron Technology, a key competitor to Samsung and SK Hynix in memory chips, rose 1.5%.
TSMC declined to comment, while Samsung and SK Hynix did not respond to requests for comment. Lam Research, KLA, and Applied Materials also did not immediately respond.
Background: In October 2022, the U.S. imposed broad restrictions on chipmaking equipment exports to China but provided foreign firms like Samsung and SK Hynix with letters authorizing shipments. In 2023 and 2024, these companies received “Validated End User” (VEU) status, which allows them to obtain U.S.-controlled products more quickly and reliably without needing multiple export licenses. However, VEU status comes with conditions such as equipment prohibitions and reporting requirements.
A Commerce Department spokesperson said chipmakers would still be able to operate in China if the authorizations are revoked. The enforcement mechanisms would align with licensing rules for other semiconductor firms exporting to China, ensuring the U.S. applies an equal and reciprocal approach.
Industry insiders warn that stricter U.S. controls could unintentionally benefit Chinese domestic competitors by making it harder for foreign companies to receive equipment, calling such a move “a gift” to China’s semiconductor industry.
