Dear Sirs,
The US Trade Representative (USTR) announced on 29 December 2025 its determination to take tariff action on semiconductors from Chinese Mainland under Section 301 of the Trade Act of 1974, with an initial tariff level of 0%, increasing in 18 months on 23 June 2027, to a rate to be announced not fewer than 30 days prior to that date.
DETAILS
2.Based on information obtained during the Section 301 investigation related to the semiconductor industry under Section 301 of the Trade Act of 1974, and in consultation with the Section 301 Committee, the USTR on 29 December 2025 issued a Federal Register (FR) notice announcing its determination to take tariff action on semiconductors from Chinese Mainland, with an initial tariff level of 0%, increasing in 18 months on 23 June 2027, to a rate to be announced not fewer than 30 days prior to that date. These new Section 301 tariffs would be additional to the existing 50% Section 301 tariff on semiconductors from Chinese Mainland imposed pursuant to the Section 301 investigation related to technology transfer. This action applies to the 8-digit Harmonized Tariff Schedule of the United States (HTSUS) subheadings listed in the notice. The concerned products shall continue to be subject to antidumping, countervailing, or other duties, fees, exactions and charges that apply to such products.
