China Section 301 Modifications to the Actions Resulting from the 2024 Four-Year Review (100% additional duty)

This is a U.S. trade measure under Section 301, a law that allows additional import duties or other actions in response to certain foreign trade practices. The title indicates a modification to actions involving products of China following a four-year review. The stated additional duty is separate from the product’s ordinary customs duty and may be added to it.

It typically affects U.S. importers bringing covered products from China, based on the product’s tariff classification and the measure’s scope. The importer should determine the correct Harmonized Tariff Schedule of the United States (HTSUS) classification, confirm the product’s country of origin, and check whether the measure applies to that classification, including any exclusions or special conditions. An additional duty can change landed cost, entry documentation, pricing, and compliance responsibilities.

What to check

• Confirm the product’s HTSUS classification using its materials, function, and construction; do not rely only on a supplier’s code.
• Verify the product’s country of origin under U.S. origin rules. Shipping through another country does not necessarily change origin.
• Check the official Section 301 measure details for the covered tariff subheadings, effective provisions, exclusions, and any product-specific requirements.
• Review the customs entry data and duty calculation to ensure the ordinary duty and any applicable additional duty are reported separately and correctly.
• Ask a licensed customs broker or trade specialist to review uncertain classifications, origin questions, exclusions, or eligibility for a special provision.
