Canada vs Mexico: Import Tariff Comparison 2026
Both Canada and Mexico are USMCA member countries, giving importers access to duty-free treatment on qualifying goods from both origins. For USMCA-qualifying shipments with no Section 338 exposure, the total tariff rate drops to 0% — bypassing the Section 122 surcharge, MFN base rate, and all other tariff layers. Section 338 is the one authority the preference does not bypass: from August 19, 2026 a retaliatory duty under 19 U.S.C. 1338 reaches in-scope Canadian goods whether or not they qualify. Non-qualifying goods from Canada face a total effective rate of 28%. Non-qualifying goods from Mexico face 28%. USMCA qualification depends on meeting regional value content thresholds and tariff classification shift rules. Importers who have not audited their USMCA qualification status may be paying significantly more than necessary on North American supply chain sourcing. The comparison of Canada vs Mexico is therefore more about logistics, supplier capabilities, and USMCA compliance than tariff rates alone.

Trade Agreement Status
Canada is a USMCA member — qualifying goods enter the US duty-free at 0% on every layer except Section 338, the retaliatory duty that reaches annexed non-Section-232 goods from August 19, 2026 and survives a USMCA preference claim. Mexico is a USMCA member — qualifying goods enter the US duty-free at 0%, and the Section 338 duty that survives a USMCA preference claim applies to Canada only, so it does not reach Mexico. For products under Section 232 national security tariffs, S232 rates govern: a bilateral deal rate does not displace them, and Section 122 never applied to S232-covered goods while it was in force, before it lapsed to zero on July 24, 2026. China-origin goods additionally face Section 301 tariffs that stack on top of all other duties, making trade agreement status a defining factor in the total tariff burden.
When to Source from Each Country
Canada offers lower tariff rates across all focus product categories in this comparison, making it the more cost-effective sourcing origin from a tariff perspective. Source from Mexico when its supplier relationships, product specialization, or geographic advantages outweigh the tariff cost differential. Always model total landed cost — including freight, insurance, MPF, and HMF fees — before finalizing sourcing decisions.

Savings Analysis
On a $10,000 shipment of auto parts components, importing from Canada saves $0 in duties compared to Mexico — a 0% reduction in total import costs. Canada incurs $2,968 in duties on the $10,000 shipment, while Mexico incurs $2,968. This difference compounds across larger order volumes and is a key factor in supplier selection decisions for importers sourcing auto parts components.
Frequently Asked Questions
The total effective tariff rate on auto parts components is 28% from Canada and 28% from Mexico under current 2026 tariff policy. These rates include the MFN base rate, any persisting bilateral deal rate, Section 232 duties for covered products, Section 301 tariffs for Chinese goods, and the forced-labor Section 301 duty that backfills the lapsed Section 122 surcharge for roughly 60 covered economies (Section 122 itself lapsed to 0% on July 24, 2026 and no longer applies).

Yes, Canada is a member of USMCA (the United States-Mexico-Canada Agreement). Goods that qualify under USMCA rules of origin enter the US at 0% duty on every tariff surcharge except Section 338, the retaliatory duty that reaches annexed non-Section-232 goods from Canada from August 19, 2026 and is not defeated by a USMCA preference claim. A qualifying good inside that annex keeps its 0% preferential rate and still owes the 50% Section 338 duty on top of it. Non-qualifying goods from Canada face the applicable tariff rates.
Yes, Mexico is a USMCA member. Qualifying goods enter the US duty-free at 0%, making Mexico one of the most competitive sourcing origins for tariff purposes. The Section 338 retaliatory duty that survives a USMCA preference claim applies to Canada only and does not reach Mexico. Non-qualifying goods face standard tariff rates.
Canada is cheaper for steel iron products with a 53% total tariff rate, compared to 53% from Mexico. On a $10,000 shipment, this 0% rate difference saves $0 in duties when sourcing from Canada.
Section 122, enacted in February 2026 for up to 150 days, imposed a global surcharge on most US imports until it lapsed on July 24, 2026. Section 122 no longer applies to Canada — it lapsed on July 24, 2026 — but Canada is on the forced-labor Section 301 covered list at the 10% tier, which backfilled the lapsed surcharge. Section 122 no longer applies to Mexico — it lapsed on July 24, 2026 — but Mexico is on the forced-labor Section 301 covered list at the 10% tier, which backfilled the lapsed surcharge. Since the lapse, a forced-labor Section 301 duty (10%/12.5% on ~60 economies) has backfilled the surcharge for most importers — model the realized post-July-24 structure, forced-labor duty included, when planning shipments.
