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

This is a U.S. Section 301 trade measure concerning certain products of China. Section 301 is a legal authority used to impose additional import duties or other restrictions in response to a foreign country’s acts, policies, or practices that the U.S. determines to be unfair or burdensome. A modification changes the product coverage or treatment of an existing Section 301 action following a review; it does not necessarily apply to every product from China.

The measure typically affects U.S. importers bringing covered Chinese-origin merchandise into the United States. The additional duty is separate from the product’s ordinary customs duty and is generally determined by the product’s tariff classification, often identified by its Harmonized Tariff Schedule (HTSUS) subheading, along with any listed exclusions, conditions, or applicable trade-remedy instructions. Importers must account for the measure when estimating landed cost, preparing entry data, and confirming whether an exclusion or other exception applies.

What to check

• Confirm the product’s correct HTSUS classification; do not rely only on a supplier’s code or product description.
• Check the official Section 301 product list and the measure’s scope notes to see whether the exact merchandise and country of origin are covered.
• Verify the product’s customs origin separately from its country of export, because Section 301 treatment generally turns on origin.
• Look for current exclusions, expiration terms, exclusions’ product descriptions, and any certification or documentation requirements.
• Ask a customs broker or trade attorney to review close classification, origin, scope, or exclusion questions before filing the entry.
