This is only the USITC HTS general-rate field. It does not include Chapter 99 or trade-remedy layers.

Section 301 / Chapter 99

Review required

Do not hard-code 7.5% or 25% from a product category or historical list. Bind the rule directly to USTR/HTS Chapter 99 sources, origin, effective dates, and exclusions.

Section 122 historical layer

Expired historical window

Do not add the expired temporary layer to a current shipment. Review it only for an applicable historical entry date against official sources.

Section 232 / product-specific remedies

Product review

Steel, aluminum, copper, autos, semiconductors, lumber, and derivatives require current annex, origin, content, and Chapter 99 review.

AD/CVD scope

Manual scope review

An HTS match is only a risk signal; the written scope of the order controls legal coverage.
