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 addressing certain acts, policies, or practices of a foreign country. This measure modifies earlier actions following a four-year review concerning China. It generally applies an additional duty to covered products of Chinese origin, on top of any ordinary customs duty and other applicable trade measures.

For an importer, the key terms are country of origin, HTSUS classification, and additional duty. The product must be classified under the correct Harmonized Tariff Schedule of the United States (HTSUS) subheading, and the measure’s product scope must match that classification and any stated descriptions or exclusions. The importer should verify the official measure details, including applicability, entry requirements, exclusions, and any interaction with other duties; a customs broker or trade attorney may be needed for difficult classification or origin questions.

What to check

• Confirm the product’s country of origin under U.S. origin rules; shipping from another country does not automatically change Chinese origin.
• Review the complete HTSUS classification, including any additional Chapter 99 reporting provision identified by the official measure.
• Compare the product’s specifications and use with the measure’s scope, notes, exclusions, and any current exclusion notices.
• Check the official source for the applicable entry or withdrawal requirements and verify whether the measure applies to the relevant import transaction.
• Keep classification, origin, product-description, and exclusion-supporting records, and seek broker or legal advice if the facts are uncertain.
