Section 301 Tariffs on Semiconductors from China

The Office of the U.S. Trade Representative has imposed an additional tariff on imports of semiconductors from China (see chart in this notice for list of affected HTSUS subheadings). This tariff will be set at zero as of Dec. 23, 2025, and will increase on June 23, 2027, to a rate to be announced not fewer than 30 days prior to that date. This new tariff will be in addition to the existing 50 percent tariff on semiconductors from China imposed pursuant to the Section 301 investigation related to forced technology transfer.

Section 301 Investigation

These actions result from a USTR Section 301 investigation announced December 23, 2024, into China’s acts, policies, and practices related to the semiconductor industry.

USTR accepted written comments on these issues between Jan. 6 and Feb. 5, 2025, and held a public hearing March 11-12, 2025. In December 2025, USTR determined that China’s acts, policies, and practices related to targeting of the semiconductor industry for dominance are unreasonable and burden or restrict U.S. commerce and are therefore actionable under Section 301 of the Trade Act of 1974.
