Section 301 tariffs are additional duties on many goods of Chinese origin, imposed by the U.S. Trade Representative under Section 301 of the Trade Act of 1974. They were introduced in 2018 and 2019 in a series of lists, most at 25% and one at 7.5%, and USTR raised rates on certain strategic products after its 2024 review. They are reported as Chapter 99 lines on the entry summary, and they are recoverable through duty drawback when the goods are exported.
Each Section 301 action covered a list of HTS numbers. If a product's base HTS number is on a list and its origin is China, the additional duty applies. Origin, not the shipping country, decides coverage, so goods made in China and shipped through another country are still covered.
USTR has granted product exclusions at various times, many of them temporary and extended in rounds. An excluded product is entered under a specific Chapter 99 exclusion number. Missing an active exclusion means paying duty that was not owed.
Did the Supreme Court ruling on IEEPA affect Section 301? No. Section 301 duties remain in force.
Does moving final assembly out of China end 301 duty? Only if the processing changes origin. Light assembly usually does not.
