China Section 301 Modifications to the Actions Resulting from the 2024 Four-Year Review (25% additional duty)

A Section 301 measure is a U.S. trade action that can impose an additional duty on qualifying goods connected to a designated country. This measure concerns certain products of China and reflects changes made after a periodic review of the underlying trade action. The additional duty is generally assessed in addition to ordinary customs duty and other applicable charges.

The key concepts are tariff classification, country of origin, and scope. An importer must identify the product’s correct Harmonized Tariff Schedule of the United States (HTSUS) classification, determine whether the goods are products of China under U.S. origin rules, and check whether that classification is listed in the measure. The measure may affect importers, customs brokers, manufacturers, and sellers whose goods enter the United States, even when the importer is not the manufacturer. Review the official measure text and current HTSUS instructions because coverage, exclusions, and effective treatment can depend on the applicable entry details.

What to check

• Confirm the product’s complete HTSUS classification; do not rely only on a supplier’s tariff code.
• Verify country of origin under U.S. customs rules, including whether processing in another country changes the origin result.
• Check the official Section 301 product list, headings, notes, exclusions, and any specified reporting or entry requirements.
• Review the measure’s effective-date and entry-status rules for the shipment, rather than applying the rule based only on the order or invoice date.
• Ask a qualified customs broker or trade specialist to review ambiguous classification, origin, exclusion, or applicability questions.
