Overview

  • The U.S. Department of Commerce is investigating TSMC for potential export control violations tied to chips found in Huawei’s Ascend 910B AI processor.
  • TSMC-produced chips for China-based Sophgo are suspected to have been diverted to Huawei, a company barred from receiving U.S.-technology-based products.
  • A potential fine exceeding $1 billion could be imposed, reflecting the value of the transactions and heightened U.S. enforcement of export regulations.
  • TSMC has denied supplying Huawei since mid-2020 and stated its cooperation with U.S. authorities in the ongoing investigation.
  • The case unfolds during sensitive U.S.-Taiwan trade negotiations, with broader implications for global semiconductor supply chains and geopolitical tensions.
