How to check Section 301 coverage

  1. Enter the HTS code. Use the 10-digit US HTS code for your product. Section 301 coverage is defined per code on the USTR lists.
  2. Pick the country of origin. Section 301 is a China-origin tariff, so origin decides whether it applies at all. Non-China origins return a definite no.
  3. Read the verdict. You get covered (with the rate), not covered, or in-scope-confirm, plus the cite. If it applies, jump to the calculator for the full stacked duty.

About Section 301

Section 301 of the Trade Act of 1974 is the authority behind the US–China tariffs. Beginning in 2018 the USTR phased in four lists covering most products of China — Lists 1–3 at 25% and List 4A at 7.5% — and in 2024/2025 raised rates on strategic goods (electric vehicles, batteries, solar cells, steel and aluminum, semiconductors and more). Coverage is defined per HTS code, so two similar products can land on different lists. Because Section 301 is additive, a Chinese-origin import often carries Section 301 and Section 232, IEEPA and the reciprocal baseline at once — see how tariff stacking works and the deeper Section 301 guide. For the combined number, run the tariff calculator; the authoritative list is the USTR Section 301 tariff actions page.

Frequently asked questions

What is a Section 301 tariff?
Section 301 of the Trade Act of 1974 lets the US impose tariffs in response to unfair foreign trade practices. In practice "Section 301" means the additional tariffs the USTR placed on products of China — Lists 1–4 (2018–19) plus the 2024/2025 increases on items like EVs, batteries, steel, aluminum and semiconductors.
How much is the Section 301 tariff?
It depends on the HTS code. Lists 1–3 are generally 25% and List 4A is 7.5%, with higher 2024/2025 rates on specific products (e.g. 100% on EVs). This checker returns the rate for codes in our dataset; confirm any code against the official USTR action list.
Does Section 301 apply to goods from countries other than China?
No. Section 301 China tariffs apply only to products of Chinese origin. Goods from Vietnam, Mexico, India and elsewhere are outside Section 301 — though they can still carry Section 232, IEEPA, the reciprocal baseline or AD/CVD.
Does Section 301 stack with other tariffs?
Yes. Section 301 is additive on top of the base/MFN duty and stacks with Section 232, IEEPA, the reciprocal baseline and any AD/CVD. Use the tariff calculator to see the full combined rate for a code and origin.
