Canada Tariffs 2026: USMCA Import Duty Guide

Updated March 25, 2026 · USMCA tariff data · USITC HTS Revision 4

Canada is the second-largest source of US imports, after Mexico. Under USMCA, most Canadian products enter duty-free or at reduced rates. However, softwood lumber remains a contentious category with additional duties, and a few other sectors face restrictions.

This guide explains USMCA treatment for Canadian goods, softwood lumber tariffs, and how to verify rates for your specific products.

Key point: Most Canadian goods (around 80% of imports) qualify for USMCA duty-free treatment. However, softwood lumber faces additional duties, and certain agricultural and energy products have restrictions. Always verify with a Certificate of Origin.

USMCA Duty-Free Treatment

Canada benefits from broad USMCA coverage. Most manufactured goods, minerals, and energy products enter at 0% tariff with a valid Certificate of Origin:

Product Category USMCA Rate MFN Rate (if applicable) Notes
Machinery & Electronics 0% 0-3% Broad coverage with USMCA
Automotive & Parts 0% 2.5-25% Rules of origin apply (75% North American content)
Chemicals & Plastics 0% 0-8% Most qualify duty-free
Oil & Natural Gas 0% 0-1% Primarily duty-free already
Minerals & Metals (excl. softwood lumber) 0% 0-5% Broadly duty-free
Softwood Lumber 0% + additional duties N/A See section below

Softwood Lumber Tariffs (Critical)

Softwood lumber is the single most contentious Canadian import. Despite USMCA, US policy imposes additional duties on Canadian lumber through:

Countervailing Duty (CVD)

The US Department of Commerce maintains a countervailing duty on Canadian softwood lumber, claiming unfair subsidies by Canadian provinces. Current rates (2026):

Anti-Dumping Duty (AD)

An anti-dumping duty is also assessed, claiming Canadian lumber is sold below fair value. Current rates:

Total Softwood Lumber Duty

When combined, Canadian softwood lumber faces:

Implications: Despite USMCA duty-free status on paper, Canadian lumber faces substantial duties. This is a major point of contention in US-Canada trade relations and is actively being negotiated.

Key Trade Categories

Automotive & Parts

Canada is the largest source of auto parts and finished vehicles. USMCA provides duty-free treatment with rules of origin:

Energy (Oil, Natural Gas, Electricity)

Minerals & Metals

Aluminum & Section 232

Like Mexico, Canadian aluminum faces Section 232 national security duties even with USMCA duty-free classification:

Agricultural Products

Certificate of Origin

To claim USMCA duty-free treatment on Canadian products, a valid Certificate of Origin must accompany the shipment. This form (CUSMA/USMCA CO) certifies:

Without a Certificate of Origin: Products are assessed standard MFN rates, which can be 3-15% higher than USMCA rates.

Note on softwood lumber: Even with a valid Certificate of Origin, CVD and anti-dumping duties apply on top of the 0% USMCA tariff. These duties are assessed automatically and are not waived by USMCA qualification.

FAQ: Canada Tariffs & USMCA 2026

Q: Do all Canadian products qualify for USMCA duty-free rates?

Almost all do, except softwood lumber (which faces CVD and anti-dumping duties regardless) and a few agricultural items with quota restrictions. Most manufactured goods, minerals, and energy products qualify duty-free with a Certificate of Origin.

Q: Why does Canadian softwood lumber still face duties under USMCA?

Softwood lumber duties (CVD and anti-dumping) are maintained under separate US trade remedy laws, not the tariff schedule. USMCA provides 0% tariff, but these additional duties are assessment separately. This is a major ongoing trade dispute.

Q: What's the total duty on Canadian softwood lumber in 2026?

Approximately 12-22% combined (CVD 9-16% + AD 2-5%) plus the February 2026 import surcharge (~2-4%). Total effective: 14-26% depending on producer.

Q: Does Section 232 aluminum duty apply to Canadian aluminum?

Yes. Even though aluminum is USMCA duty-free (0% tariff), Section 232 national security duties apply on top (typically 10% on primary aluminum). These duties are not waived by USMCA.

Q: How do I claim USMCA duty-free treatment on Canadian goods?

Your Canadian supplier must provide a CUSMA/USMCA Certificate of Origin. Present this to US Customs when the shipment arrives. Without it, standard MFN rates apply.

Q: Do dairy products from Canada qualify for USMCA duty-free rates?

Partially. USMCA provides lower rates on dairy, but tariff-rate quotas (TRQ) limit duty-free quantities. Excess quantities face tariffs of 20-35%. Check current TRQ status with Customs.
