CBP guidance implements USTR conforming amendments to five Section 301 China product exclusions, updating HTSUS statistical reporting numbers effective July 1, 2026.

This is a Section 301 measure involving products from China. Section 301 is a US trade remedy authority used to impose additional import measures in response to certain foreign trade practices. A product exclusion is an exception that can remove or change the application of an additional Section 301 duty when the product meets the exclusion’s scope and other requirements.

The guidance updates HTSUS statistical reporting numbers to conform to changes made by the United States Trade Representative (USTR). The HTSUS is the Harmonized Tariff Schedule of the United States, and statistical reporting numbers are the detailed digits used to report imported merchandise. The update matters because an importer must use the correct classification and reporting number to claim an exclusion, calculate duties, and file accurate entry data with US Customs and Border Protection (CBP).

What to check

• Confirm the product’s full HTSUS classification, including the statistical reporting number, using the current official HTSUS and CBP guidance.
• Read the exclusion’s product description carefully; do not rely only on a general product name or an HTSUS number, because scope language controls eligibility.
• Check whether the product’s country of origin and entry circumstances meet the Section 301 requirements for the exclusion.
• Review entry instructions in the Automated Commercial Environment (ACE) and confirm that the exclusion claim is reported using the applicable current code or data element.
• Keep specifications, invoices, classification analysis, and other records supporting the exclusion claim; consult a customs broker or trade counsel if the product does not clearly fit the scope.
