US Section 301 List Check

For China-origin Section 301 research. Search results are USTR's published action records, not a total tariff or a finding that a particular shipment is covered.

Confirm classification

Use the saved HTS hierarchy and the official current schedule to confirm the full US reporting number. A changed or deleted code needs a fresh classification check.

Read the applicable legal provision

Use the relevant Chapter 99 Subchapter III notes and USTR action notices. Original dates in search records describe the action; they are not a verified rate for every later entry date.

Check product scope and exclusions

Read USTR exclusions and CBP guidance against the goods' description, origin and entry date. A code-only result cannot decide an exclusion or all other duties.

Before treating a base rate as your import duty

Check Chapter 99, especially the relevant Subchapter III U.S. notes for Section 301 and Section 232, then review CBP trade-remedy guidance. Coverage can depend on more than the HS chapter or the country shipped from. The presence or absence of an endnote has no legal effect.

Official sources and snapshot method

All official export rows are retained, including unnumbered description levels. Ten-digit rows with entirely blank duty columns display the complete rate tuple of their matching eight-digit legal ancestor, with that source identified. Units and footnotes remain as exported.

Code searches preserve every digit, including leading zeroes. Keyword searches include parent descriptions so lines named “Other” can be found. Partial English words can match longer words; a keyword match is a discovery aid and does not classify a product.

The USTR file is used by its official product-search page. It supplies action text rather than a versioned legal rate table, and labels its article descriptions unofficial. This tool preserves historical actions, duplicate code entries, scheduled changes and code-specific notes. It checks whether each code exists in the saved USITC edition.

The tools do not compute a combined duty, automatically grant a Special program, decide an exclusion or determine AD/CVD scope. Review the legal provisions and CBP instructions for your shipment. Every source link below is associated with the displayed source-check date.
