A New 10% Tariff on Canadian Goods Just Took Effect — But It Only Hits What CUSMA Doesn't Already Cover

What This Means for You

Canada is now dealing with two separate U.S. tariff actions inside the same week, and confusing the two could lead a business to either over-react or under-prepare. On July 20, President Trump signed an order placing 50% tariffs on a named list of Canadian goods effective around August 19. On July 24, a different and legally distinct measure took effect: a new 10% tariff on Canadian goods tied to a forced-labour investigation, replacing a separate stopgap tariff that had just expired. Based on our review of how this new tariff is structured, the single most important fact for most Canadian businesses is this: goods that already qualify for duty-free treatment under CUSMA (the Canada-U.S.-Mexico free trade agreement, formerly known as NAFTA) are exempt from it. Here is how to figure out whether that exemption actually covers you.

If You Export Goods to the U.S. and Aren't Certain of Your CUSMA Status:

Immediate action:

• Confirm your CUSMA "rules of origin" status this week, not eventually. This single document determines whether your product is exempt from the new 10% tariff. A customs broker or the Canada Border Services Agency's trade tariff finder (cbsa-asfc.gc.ca) can confirm your product's status within days.
• Pay particular attention if your product uses imported components. If you assemble or manufacture in Canada using parts sourced from countries facing the new tariff's higher 12.5% tier, you need to verify your product still meets CUSMA's "substantial transformation" threshold to qualify as Canadian-origin. If it does not, your finished product could face the 10% tariff on export to the U.S., separate from whatever your component supplier is now paying to bring those parts into Canada.
• Do not assume this is the same tariff you already prepared for. If you modelled your exposure to the July 20 order — which named specific categories like dairy, wine, cement, furniture, and clothing — this is an additional and separate 10% measure that applies more broadly to non-CUSMA-compliant goods across categories, not just the named list.

What to prepare:

• Document your supply chain's labour practices, since the U.S. action is framed as a forced-labour enforcement measure under Section 301 of the Trade Act of 1974, not a straightforward economic tariff. Canadian exporters with fully traceable, Canadian- or CUSMA-sourced supply chains have the strongest position to demonstrate compliance if a shipment is challenged at the border.
• Ask your industry association whether Canada's own forced-labour import prohibitions, in place under Canada's Customs Tariff since 2020, are relevant to your file. Trade Minister Dominic LeBlanc has publicly argued Canada already has "one of the world's most robust frameworks to prevent and address forced labour," which is the basis for Ottawa's argument that the measure should not apply to genuinely Canadian-made goods.
• Build a version of your cash-flow model that assumes both tariff actions apply simultaneously to any non-CUSMA-compliant, non-exempt share of your U.S.-bound sales, since the 50% order and the 10% forced-labour tariff are legally separate and could both affect the same shipment if it fails to qualify for CUSMA treatment.

Example scenario: An Ontario furniture manufacturer sources hardware components from Vietnam — one of the countries facing the new tariff's higher 12.5% tier — and assembles finished furniture in Canada. If that finished furniture meets CUSMA's substantial transformation rules, it remains exempt from this week's 10% forced-labour tariff regardless of the Vietnamese input costs, though it may still be exposed to the July 20 order, since furniture appears on that separate list. If the assembly does not meet CUSMA's origin threshold, the manufacturer could face the 10% tariff on top of whatever the July 20 order applies — a gap worth closing with a customs broker before shipping, not after a shipment is held at the border.

If You Run a Small Business That Only Sells Domestically:

• Expect limited direct price impact. Since CUSMA-compliant goods are exempt, and the tariff applies to U.S. imports of foreign goods rather than to sales inside Canada, this measure does not directly raise shelf prices for Canadian consumers the way a Canadian retaliatory tariff on U.S. imports would.
• Watch the categories where CUSMA compliance is lower, such as electronics and goods with significant non-North American components, since those are more likely to see cost pass-through if a Canadian retailer's supplier is affected.

For All Canadians:

The more durable story here is not the 10% number — it's the legal tool. According to Bloomberg and CBS News, this tariff was imposed under Section 301 of the Trade Act, a trade-remedy statute, replacing a stopgap Section 122 tariff that had been used after the U.S. Supreme Court struck down an earlier round of tariffs imposed under a different legal authority (the International Emergency Economic Powers Act). Section 301 tariffs are generally harder to challenge in U.S. courts than the emergency-powers tariffs that were struck down earlier this year. If you're trying to judge whether U.S. tariff actions against Canada are likely to persist or get reversed through litigation, the legal basis behind each individual measure matters as much as the headline percentage.

The News: What Happened

According to Bloomberg, CBS News, and CBC News, the Trump administration's new tariffs took effect on Friday, July 24, 2026, applying to roughly 60 U.S. trading partners following a Section 301 investigation into whether those countries had failed to adequately restrict forced labour in their supply chains. According to BNN Bloomberg, Canada, Mexico, and the United Kingdom face a 10% tariff rate, reflecting their existing forced-labour restrictions, while a larger group of countries assessed as having weaker protections face tariffs as high as 12.5%.

Critically, according to BNN Bloomberg, "the new duties will not apply to goods compliant under the Canada-U.S.-Mexico Agreement on trade, known as CUSMA, so it is not expected to affect the tariff regime Canada has been under since February." This measure replaces an earlier stopgap tariff imposed under Section 122 of the Trade Act, which had itself been introduced after the U.S. Supreme Court struck down a broader set of tariffs the administration had imposed under emergency economic powers legislation.

According to BNN Bloomberg, Canada's Trade Minister Dominic LeBlanc called the move "not unexpected" but pushed back on its application to Canadian goods, stating that Canada has "one of the world's most robust frameworks to prevent and address forced labour, backed by strong legislative and enforcement measures" and arguing "there is no basis for the imposition of additional Section 301 duties on Canadian goods." The Canadian Chamber of Commerce's Matthew Holmes described the timing of the measure as "somewhat suspect," according to BNN Bloomberg, and recommended multilateral coordination on forced-labour enforcement rather than unilateral tariff action. In the United States, the small-business coalition We Pay The Tariffs criticized the measure as pretextual, pointing to what it described as inconsistent targeting of countries.

Analysis: Why This Matters

Based on our analysis of the timing and legal structure of this measure, its arrival just four days after the July 20 order targeting named Canadian goods is best understood as two parallel tracks of the broader Canada-U.S. trade dispute, rather than an escalation of the same measure. The July 20 order is a bilateral, product-specific action tied to disputes over dairy market access and provincial alcohol delisting. This July 24 measure is a multilateral, process-based action tied to a Section 301 investigation that covers dozens of countries at once, of which Canada is only one.

Historical Context:

The Trump administration has cycled through several legal tools for imposing tariffs over the past year, including tariffs under the International Emergency Economic Powers Act that the Supreme Court struck down earlier in 2026, a stopgap Section 122 global tariff that has now expired, and product-specific orders like the July 20 action. Section 301, the tool used for this latest measure, is a longer-standing trade statute more commonly associated with intellectual property and unfair-trade-practice disputes, and it carries a different legal foundation than the emergency-powers tariffs that courts have already rejected.

What Happens Next:

Watch for two things: whether Canada's argument that its existing forced-labour enforcement framework should exempt it from the measure gains any traction in future negotiations, and whether CUSMA's exemption holds in practice as U.S. Customs and Border Protection begins enforcing the new tariff at the border. Since the exemption depends on paperwork — proof of CUSMA-origin status — the practical risk for Canadian exporters over the next few months is less about the tariff rate itself and more about whether their own origin documentation is airtight.

Your Action Plan

Immediate (This Week):

• Confirm your product's CUSMA rules-of-origin status with a customs broker if you export to the U.S. and are not already certain of it.
• If your supply chain includes components from any of the roughly 60 countries named in the Section 301 investigation, document their sourcing.

Short-term (This Month):

• Separate your risk modelling for the July 20 order (50%, named goods list, effective ~August 19) from this July 24 measure (10%, non-CUSMA-compliant goods generally, effective now).
• Ask your industry association whether Global Affairs Canada is tracking any relief or remission process specific to this measure.

Long-term (This Year):

• Monitor whether CUSMA's exemption from this tariff remains stable as broader Canada-U.S. trade negotiations continue.
• If you rely on non-North American component suppliers, evaluate whether shifting sourcing to CUSMA-region suppliers reduces your long-term tariff exposure across multiple current and future U.S. trade actions.

Other Perspectives

Canadian Government:

Trade Minister Dominic LeBlanc has argued Canada's existing forced-labour enforcement framework already meets the standard the U.S. measure is meant to enforce, and that additional duties on Canadian goods are unwarranted.

Canadian Business Groups:

The Canadian Chamber of Commerce has questioned the timing of the measure and called for multilateral coordination on forced-labour enforcement rather than unilateral country-by-country tariffs.

American Business Groups:

The U.S. small-business coalition We Pay The Tariffs has criticized the measure as pretextual, arguing the countries targeted and the rates assigned do not consistently track actual forced-labour risk.

Independent Commentary:

Globe and Mail business commentary has described the U.S. action as, in part, a negotiating tactic, while acknowledging that supply-chain forced-labour risk is a genuine and underexamined issue for many countries' import streams — a reminder that a measure can be both strategically timed and substantively grounded at the same time.
