Review Section 301 tariff workflow: China-origin goods, USTR lists, exclusions, HTS matching, source snapshots, and landed-cost planning.
Section 301 tariffs are additional duties tied to USTR actions, most notably China-origin goods. To verify a product, match the HTS subheading against USTR lists and modifications, check exclusions and expiration dates, then keep the Section 301 layer separate from the base MFN duty in your landed-cost model.
Use official Section 301 tariff-action and exclusion resources.
Small classification differences can change applicability.
Keep it separate from base duty and other trade remedies.
The base MFN rate comes from the HTS. Section 301 is an additional layer that may apply after you identify the product, origin, and relevant USTR list.
Review USTR lists, modifications, exclusions, Chapter 99 references, effective dates, and any CBP implementation guidance. If the product also touches steel, aluminum, AD/CVD, or quota rules, review those separately.
Planning-only notice: TariffsChart is not a customs broker, law firm, tax advisor, or government authority. Verify classifications, rates, effective dates, exclusions, and filing instructions with official sources and qualified professionals.
No. Applicability depends on HTS coverage, origin, USTR actions, exclusions, and effective dates.
No. It is an additional duty layer and should be modeled separately.
Yes for planning: save the base HTS result, add a Section 301 assumption, attach USTR source links, and prepare a broker review packet.
