Published preference indicator
Checks whether the HTS Special column identifies a program for the code and origin supplied.
Screen an HTS code and origin for a special-program indicator, compare the published preferential rate, and surface the documentation and rules-of-origin work still required.
A special rate shown in the HTS is a candidate, not proof that the shipment qualifies. Product-specific origin rules, production records, direct-shipment requirements, and certification obligations must be validated before making a preference claim.
What the screener checks
Checks whether the HTS Special column identifies a program for the code and origin supplied.
Shows the published general and candidate special rates so the potential difference is visible.
Marks the result for verification instead of claiming a tariff shift, RVC test, or product-specific rule has been proven.
Before claiming preference
USMCA example
Use the Special column to find a possible USMCA rate, then verify the product-specific rule and supporting production records. The screener does not certify originating status.
