HTS Code Lookup in 2026: Base Classification Plus Chapter 99 Checks
Use the current HTS and CBP rulings, then evaluate each event-specific Chapter 99 measure and exception.
No universal current U.S. tariff rate is available from country of origin alone.
Classification, product scope, origin, entry time, MFN treatment, Section 232 status, and exemptions can change the result. When any required selector is missing, the safe output is indeterminate / review required.
What the reviewed sources support
- The USITC lookup provides the base classification framework. It does not by itself resolve every Chapter 99 overlay or exception.
- The former Section 122 surcharge reached its stated endpoint. Brazil, forced-labor, and Canada actions each have their own product schedules and exceptions.
- Return indeterminate whenever the full HTS, product scope, entry time, or exemption state is missing.
What to do before pricing or filing
- Confirm the complete HTS classification and the product description used for entry.
- Check the current HTSUS and controlling Chapter 99 notes for the entry date.
- Evaluate product schedules, transition rules, Section 232 interaction, and exclusions.
- Keep the result in review-required state until every selector and source is resolved.
The Attahir Labs rate table and TariffShield use fail-closed containment while the legacy country snapshots lack current row-level provenance. They must not supply a current numeric customs result.
