Section 301 review links USTR notices, exclusion windows, HTS scope, China-origin exposure, and comment deadlines into one importer review path.
This page is the public entry point. It explains the issue, links to the public tools that surface the primary records, and routes repeat work into review.
Use this when the first question is which USTR notice, modification, review, hearing, or comment window created the signal.
Use this when a product line needs to be matched against HTS coverage, China-origin exposure, and list-specific language.
Use this when the duty answer depends on an exclusion, extension, expiration, revocation, or product-specific status change.

Review the issue when the same HTS line, China-origin product, supplier, exclusion term, or USTR action needs repeat review instead of a one-time public lookup.

The U.S. has applied layered tariffs on South Korean goods since 2025 under Section 232, Section 301, Section 122, and IEEPA authority, partially offset by the 2025 U.S.-Korea Strategic Trade and Investment Deal that capped auto and pharma tariffs at 15% and reduced the country-specific rate from 25% to 15%.
