The move comes as the US Commerce Department moved to end the "validated end-user" (VEU) program allowing select foreign semiconductor manufacturers to export US-origin goods and tech license-free to make chips in China.

"TSMC has received notification from the US Government that our VEU authorization for TSMC Nanjing will be revoked effective December 31, 2025," said a spokesperson for Taiwan Semiconductor Manufacturing Company on Tuesday.

"While we are evaluating the situation and taking appropriate measures, including communicating with the US government, we remain fully committed to ensuring the uninterrupted operation of TSMC Nanjing," TSMC added in a statement.

TSMC is the world's largest contract maker of chips that are used in everything from smartphones to missiles, and counts Nvidia and Apple among its clients.

But the center of its most advanced manufacturing remains in Taiwan.

On Friday, the Commerce Department's Bureau of Industry and Security said that former VEU participants will have 120 days after the new rule is published in the Federal Register to apply for and receive export licenses.

But while the bureau plans to grant licenses to allow these businesses to run existing China-based plants, it does not plan to issue licenses for them "to expand capacity or upgrade technology," it said.
