(Reuters) -The U.S. Department of Commerce is considering revoking authorizations granted in recent years to global chipmakers Samsung, SK Hynix and TSMC, making it more difficult for them to receive U.S. goods and technology at their plants in China, according to people familiar with the matter.
The chances of the United States withdrawing the authorizations are unclear. But with such a move, it would be harder for foreign chipmakers to operate in China, where they produce semiconductors used in a wide range of industries.
A White House official said the United States was "just laying the groundwork" in case the truce reached between the two countries fell apart. But the official expressed confidence that the trade agreement would go forward and that rare earths would flow from China, as agreed.
"There is currently no intention of deploying this tactic," the official said. "It's another tool we want in our toolbox in case either this agreement falls through or any other catalyst throws a wrench in bilateral relations."
Shares of U.S. chip equipment makers that supply plants in China fell when the Wall Street Journal first reported the news earlier on Friday. KLA Corp dropped 2.4%, Lam Research fell 1.9% and Applied Materials sank 2%. Shares of Micron, a major competitor to Samsung and SK Hynix in the memory chip sector, rose 1.5%.
A TSMC spokesman declined comment. Samsung and Hynix did not immediately respond to requests for comment. Lam Research, KLA and Applied Materials did not immediately respond, either.
A company with VEU status is able to receive designated goods from a U.S. company without the supplier obtaining multiple export licenses to ship to them. VEU status enables entities to receive U.S.-controlled products and technologies "more easily, quickly and reliably," as the Commerce Department website puts it.
The VEU authorizations come with conditions, a person familiar with the matter said, including prohibitions on certain equipment and reporting requirements.
“Chipmakers will still be able to operate in China," a Commerce Department spokesperson said in a statement when asked about the possible revocations. "The new enforcement mechanisms on chips mirror licensing requirements that apply to other semiconductor companies that export to China and ensure the United States has an equal and reciprocal process.”
Industry sources said that if it became more difficult for U.S. semiconductor equipment companies to ship to foreign multinationals, it would only help domestic Chinese competitors.
"It’s a gift," one said.
