Import Duty from Mexico to the U.S. in 2026: USMCA Plus Product Checks
USMCA qualification and the July Section 301 action are separate tests; Mexico does not have one current all-product rate.
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
- USMCA can provide a preference when the product satisfies its rules of origin and documentation requirements.
- The July forced-labor Section 301 action is a separate product-targeted measure with timing and exception rules.
- Do not turn Mexico origin or USMCA eligibility into one universal all-in duty number.
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.
