China Section 301 List 4 (Modification) (7.5% additional duty)

A Section 301 measure is a U.S. trade action that can impose an additional duty on covered products from a particular country. “China Section 301 List 4 (Modification)” refers to a later change to the products covered by a List 4 action. The additional duty is separate from the product’s normal customs duty and may apply only when the merchandise meets the measure’s product and origin requirements.

This typically matters to importers bringing Chinese-origin goods into the United States, including products purchased through suppliers or marketplaces. Coverage is determined mainly by the product’s Harmonized Tariff Schedule of the United States (HTSUS) classification, country of origin, and the applicable measure instructions. A product’s ordinary tariff classification alone does not automatically prove that the Section 301 measure applies; the importer must compare the exact HTSUS provision and any listed exceptions, exclusions, or modifications with current official guidance.

What to check

• Confirm the product’s correct HTSUS classification, using the goods’ material, function, construction, and other classification facts—not just the supplier’s description.
• Verify country of origin under U.S. origin rules; the shipping location or seller location may differ from the product’s customs origin.
• Check the current Section 301 list, modification language, product descriptions, and any exclusions or special reporting instructions in official U.S. sources.
• Review the measure’s effective rules for the relevant entry and filing circumstances, including how the additional duty is reported separately from the ordinary duty.
• Keep product specifications, sourcing records, classification support, and origin documentation; ask a customs broker or trade specialist to resolve uncertain classifications or eligibility questions.
