China Section 301 Modifications to the Actions Resulting from the 2024 Four-Year Review (50% additional duty)

A Section 301 measure is a U.S. trade action that can impose an additional duty on certain imported goods from a specified country. This measure concerns modifications to the actions resulting from a review of China-related trade measures. The additional duty is generally collected in addition to the ordinary customs duty and any other applicable import charges.

It typically affects products that are classified under listed Harmonized Tariff Schedule of the United States (HTSUS) subheadings and that have China as their country of origin. The key terms to understand are tariff classification, country of origin, additional duty, and entry filing. An importer must determine whether the product’s HTSUS classification and origin match the scope of the measure; the product’s brand, seller location, or shipping route does not by itself establish origin.

What to check

• Verify the product’s complete HTSUS classification, including any required statistical suffix, and compare it with the official Section 301 product list or instructions.
• Confirm the product’s country of origin under U.S. origin rules; do not rely only on the country where the item was purchased, shipped, or assembled.
• Check whether an exclusion, exception, quota treatment, or other special instruction applies, and confirm its scope and validity in current official sources.
• Review whether the Section 301 additional duty is owed alongside ordinary duty, antidumping or countervailing duties, merchandise processing fees, or other applicable charges.
• Keep supporting records for classification, origin, product specifications, and any exclusion claim, and ask a customs broker or trade professional to review uncertain cases.
