U.S. Section 338 Actions on Canadian Alcohol, Dairy, and Motor Products
The three Section 338 actions are future, listed-product measures—not a current tariff on all Canadian goods.
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 three proclamations provide a future 50% additional duty for listed alcohol, dairy, and motor-vehicle products beginning August 19.
- They are not a tariff on all Canadian goods and do not terminate USMCA.
- Do not calculate a current Section 338 amount before the effective-instant HTSUS and CBP implementation state is verified.
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.
