Section 301 China Product Exclusions Conforming Amendment

On September 2, 2026, the U.S. Trade Representative (USTR) made conforming amendments to four Section 301 China product exclusions which exempt certain products from Section 301 China duties ranging from 7.5%-25%. The amendment is to conform with changes to the ten-digit statistical reporting categories of the Harmonized Tariff Schedule of the United States (HTSUS) effective July 1, 2026.

Product exclusions are available to all importers for goods described by the product exclusion description. If there is no specific description, then all items properly classified under the listed number(s) can take advantage of the exclusion.

Effective Date

The amendments are retroactive to July 1, 2026, and are available in ACE starting at noon on September 23, 2026.

Post Summary Correction

To request a refund of Section 301 duties paid on previous imports of products granted duty exclusions by the USTR, importers may file a Post Summary Correction (PSC) if within the PSC filing timeframe. If the entry is beyond the PSC filing timeframe, importers may protest the liquidation if within the protest filing timeframe.

For example, if importers enter Chinese goods during the period July 1, 2026 through September 22, 2026, subject to the conforming amendments under HTSUS classification 9903.88.69, and pay Section 301 China duties, importers should file a PSC on or after September 23, 2026, to obtain a refund of duties paid.
