Washington swaps an expiring global levy for a Section 301 ‘forced labour’ tariff, hitting Canada at 10 percent while sparing CUSMA-compliant goods

OTTAWA, July 24, 2026. The United States moved on Thursday to impose a fresh set of tariffs on dozens of trading partners, including Canada, invoking concerns about forced labor in global supply chains just hours before an earlier tariff authority was set to lapse. Canada was assigned a 10 percent rate, at the lower end of a scale that reaches 12.5 percent for most other affected countries, and the new duties spare goods that comply with the Canada United States Mexico Agreement.
The measure, issued under Section 301 of the Trade Act of 1974, replaces a temporary global levy that had underpinned much of the administration’s tariff wall and was due to expire Friday. Canadian officials cast the announcement as unwelcome but expected, and emphasized that the CUSMA carve-out should sharply limit its practical reach for compliant exporters. Business groups, however, questioned both the timing and the rationale.
“President Trump recognizes that decades of moral suasion have not eradicated forced labour from global supply chains,” U.S. Trade Representative Jamieson Greer said in announcing the duties. “The United States has had a forced labour import ban for nearly a century, and rigorously enforces it. It’s well past time for our trading partners to do the same.”
How the new tariff is structured
Canada, Mexico and the United Kingdom are among the countries assigned the 10 percent rate, while a longer list of nations faces 12.5 percent. Crucially for Canadian exporters, the administration built in an exemption for goods compliant with CUSMA, known in the United States as USMCA, and preserved existing carve-outs for certain products. Because most Canada United States trade already moves under CUSMA rules of origin, officials say the practical footprint of the new duty on Canadian goods should be modest.
The Section 301 action does not stand alone. Canada continues to face separate American tariffs on steel, aluminum, automobiles and, more recently, cabinetry, and this week Trump also signed orders threatening a 50 percent tariff on a broad list of consumer goods under a different legal authority. The forced-labor duty is best understood as one layer in an increasingly stacked structure of overlapping U.S. trade measures.
The differential rates are themselves a diplomatic signal. By placing Canada, Mexico and the United Kingdom in the 10 percent tier while assigning 12.5 percent to most other affected nations, Washington drew a distinction between partners it regards as closer or more cooperative and the broader field. For Canada, the lower rate offered cold comfort, since officials had argued the country should face no new duty at all, given its existing legal prohibition on forced-labor imports. The inclusion of the United Kingdom, which sits outside North America’s trade bloc, in the same tier as the two CUSMA partners suggested the tiers reflect diplomatic standing as much as trade structure.
A century-old prohibition, newly invoked
The United States has maintained a statutory ban on imports made with forced labor for nearly a century, and in recent years has enforced it aggressively through detention orders that hold suspect shipments at the border. Greer leaned on that history in framing the new tariffs, arguing that decades of moral suasion had failed and that trading partners should now match American enforcement. Canada, for its part, enacted its own import prohibition and built a supply-chain reporting regime around it, which is why Ottawa reacted with particular irritation to a finding that it had failed to enforce its rules.
The dispute therefore turns less on whether forced labor should be kept out of supply chains, a goal both governments profess to share, than on whether tariffs are a legitimate tool to enforce that goal against a partner with its own robust regime. Ottawa’s position is that penalizing Canada does nothing to address forced labor in the higher-risk jurisdictions where the problem actually originates, and that a tariff aimed at a close ally is a blunt instrument poorly matched to the stated objective.
The legal backdrop
The timing is a product of Washington’s own legal calendar. Earlier this year the U.S. Supreme Court struck down the tariff tool the administration had used for its “Liberation Day” and fentanyl-related duties. To fill the gap, the administration turned to Section 122 of the Trade Act of 1974, which permits a temporary global duty of up to 15 percent but expires automatically unless Congress acts. That authority was set to lapse Friday, the same moment the new Section 301 duties take effect.
Trade specialists have described the Section 301 investigations, which examined forced labor across roughly 60 countries, as a more durable and legally resilient foundation for the administration’s tariffs than the emergency powers the courts have curtailed. In its justification, the U.S. trade office asserted that “Canada has failed to effectively enforce its forced labour import prohibition,” a finding Ottawa firmly rejects.
The sequence illustrates how the administration has repeatedly rebuilt its tariff architecture as courts and statutes have constrained it. The emergency economic powers used for the earliest rounds fell to a Supreme Court ruling. Section 122 provided a temporary bridge but came with a statutory clock. Section 301, which requires formal investigations and findings, is slower to deploy but harder to dislodge, and trade lawyers expect it to become a mainstay of American tariff policy precisely because it rests on firmer legal footing.
That durability matters for Canadian planners. A tariff grounded in a Section 301 finding is less likely to be struck down or to expire on its own than one built on emergency authority, which means the forced-labor duty could persist even as other, more legally fragile measures come and go. Businesses weighing whether to treat the 10 percent rate as temporary noise or a lasting feature of the landscape should lean toward the latter, at least until the underlying finding is contested through litigation or resolved through negotiation.
Ottawa’s response
Canada United States Trade Minister Dominic LeBlanc said the measure forms part of a broader pattern of unilateral American trade actions but “is not unexpected,” noting Washington had signaled its intention to replace the expiring baseline levy. He highlighted the elements that soften the blow for Canada. “Notably, the new Section 301 tariffs include an exemption for USMCA-compliant goods, maintain existing exemptions for certain products, and will be applied at a 10 percent tariff rate for Canada and a small number of countries, rather than the 12.5 percent applied to the remaining countries,” he said.
LeBlanc argued that Canada already shares the stated objective of keeping goods made with forced labor out of supply chains, and that its framework is among the world’s strongest. “That is why Canada has one of the world’s most robust frameworks to prevent and address forced labour, backed by strong legislative and enforcement measures,” he said, adding that Ottawa introduced new legislation last month to further strengthen enforcement. He pledged to “continue engaging constructively with the United States on this matter, as well as other outstanding issues, over the coming weeks.”
The government had lobbied Washington to spare Canada on precisely these grounds. In a written submission to Greer’s office earlier this month, Ottawa argued that “in light of Canada’s existing prohibition, complementary supply chain transparency measures, newly introduced stand-alone forced labour import legislation and continued commitment to Canada U.S. co-operation, Canada respectfully submits that there is no basis for the imposition of additional Section 301 duties on Canadian goods.”
LeBlanc’s measured tone reflected a broader strategy of keeping channels open. Rather than announce immediate countermeasures, Ottawa signaled it would continue to press its case through negotiation, emphasizing shared objectives on forced labor and pointing to its strengthened legislation as evidence of good faith. The approach mirrors the federal government’s handling of the larger tariff dispute, where it has favored engagement over confrontation while reserving the right to respond. With a separate and far larger 50 percent tariff threat looming in August, officials were plainly reluctant to open a second front over a measure whose practical bite on Canada is comparatively small.
New legislation at the center
At the heart of Canada’s case is a bill tabled last month, Bill C-35, designed to sharpen enforcement of the country’s existing ban on imports made with forced labor. The legislation would create a public list of products linked to forced labor in specific regions, drawing on intelligence from embassies and other authorities, and would require importers to prove that goods from listed regions were not produced through slavery. It builds on an earlier regime that already obliges companies to file annual reports to the federal government.
The reform matters well beyond the current tariff dispute. If enacted, Bill C-35 would shift a meaningful compliance burden onto importers, who would need documented, auditable supply-chain due diligence to bring in goods from flagged regions. Canadian businesses that source components or raw materials from higher-risk jurisdictions should begin preparing traceability systems now, regardless of how the tariff question is resolved.
The bill also carries a diplomatic purpose. By publishing a product-and-region list and requiring importers to rebut a presumption of forced labor, Canada would move its regime closer to the American model, blunting the argument that it fails to enforce its own prohibition. Ottawa has effectively offered the legislation as evidence that the two countries are converging on enforcement, and as grounds for why a punitive tariff is unwarranted between partners pursuing the same end.
One layer among many
The forced-labor duty does not replace the other tariffs Canada faces; it adds to them. Canadian exporters already contend with Section 232 duties on steel and aluminum, levies on automobiles, and more recent tariffs on cabinetry, alongside the separate 50 percent threat on consumer goods scheduled for August. Each measure operates under its own legal authority, with its own exemptions, rates and effective dates, and the cumulative complexity has become a compliance burden in its own right.
Customs brokers and trade-compliance teams now must determine, product by product, which authorities apply, whether CUSMA compliance offers shelter, and how duties interact when more than one attaches to the same good. For smaller firms without dedicated trade counsel, that complexity can be as costly as the duties themselves, consuming management time and raising the risk of expensive classification errors that surface only in a customs audit.
Business groups push back
The Canadian Chamber of Commerce questioned the timing of the announcement, which landed as the previous tariff authority sunset. “The timing is somewhat suspect,” said Matthew Holmes, the chamber’s executive vice-president and chief of public policy. “Canada is a leader on this, with a formal prohibition on the importation of goods produced with forced labour, more legislation coming to strengthen this regime, and businesses investing significantly in compliance, due diligence and supply chain transparency.” He argued that a genuine effort to combat forced labor “should be a co-ordinated approach through a multilateral mechanism.”
Criticism was not confined to Canada. We Pay the Tariffs, a coalition of about 1,200 American small businesses, called the stated rationale a pretext. “You can’t address potential forced labor concerns in Cote d’Ivoire by slapping tariffs on Australian wine and Swiss cheese,” said executive director Dan Anthony. “Yet that is what we are supposed to believe from this Section 301 action.” The administration countered that the investigations have already prompted some trading partners to tighten their own forced-labor import rules, with Greer saying he was “encouraged” by partners that moved quickly.
The divergence between the administration’s stated aim and the tools it chose is central to the criticism. Forced labor is concentrated in a handful of high-risk regions and industries, yet the tariffs sweep in goods and countries with little plausible connection to the problem. Critics argue that a targeted, intelligence-led approach coordinated with allies would do more to root out abuses than a broad tariff that functions, in practice, as a revenue and leverage measure dressed in the language of human rights. Supporters counter that only the threat of lost market access moves reluctant governments to act.
Economic impact
Judged in isolation, the forced-labor tariff is unlikely to reshape the Canadian economy. The CUSMA exemption shields the large majority of bilateral trade, the 10 percent rate is lower than that applied to most other targeted countries, and existing product carve-outs remain intact. For the many exporters whose goods already qualify under rules of origin, the measure may change little in day-to-day terms.
The concern is cumulative. The new duty stacks atop sectoral tariffs on metals, autos and cabinetry, and arrives alongside the separate 50 percent threat on consumer goods. Each layer adds administrative complexity, compliance cost and uncertainty, and the aggregate weight is what worries Canadian manufacturers. Uncertainty over the future of CUSMA itself, which failed to secure a formal renewal at a joint review earlier this month even as Canada and Mexico backed an extension, compounds the difficulty of long-term planning.
For the Canadian economy as a whole, the forced-labor tariff barely registers against the backdrop of the larger measures in play. Its narrow scope, once the CUSMA exemption is applied, means the affected trade is a fraction of what the 50 percent consumer-goods order would touch. The more important question is what the measure reveals about American intentions, namely a willingness to keep constructing new tariff authorities even as older ones are struck down or replaced, and to apply them to close allies as readily as to distant competitors.
There is also a pricing dimension for the goods that do fall outside CUSMA protection. Even a 10 percent duty can tip marginal transactions into unprofitability, and exporters operating on thin margins may find the tariff, small in aggregate, is decisive at the level of a specific contract. Those firms should not assume the measure is immaterial simply because its economy-wide footprint is modest, and should model its effect line by line on the products that do not qualify under rules of origin.
Implications for importers and exporters
For Canadian exporters, the first order of business is to verify CUSMA compliance for every product line bound for the United States. Goods that qualify under rules of origin should be documented rigorously, since the exemption is the single most important shield against the new duty. Exporters of goods that do not currently qualify should assess whether adjustments to sourcing or production could bring them within the agreement’s terms.
On forced-labor compliance specifically, both Canadian importers and their U.S. counterparts should treat the Section 301 action and Bill C-35 as a signal that supply-chain due diligence is becoming a hard requirement rather than a reputational nicety. Firms should map their suppliers to the country and, where possible, the facility level, retain documentation proving goods were not made with forced labor, and monitor the product and region lists that both governments are moving to publish. Companies importing American goods into Canada should also watch for any Canadian countermeasures that could raise the cost of U.S. inputs.
American enforcement of its own ban has shown that goods can be detained on suspicion alone, leaving importers to prove a negative under time pressure while shipments sit idle and carrying costs mount. Under Canada’s proposed regime, the burden of proof would similarly shift toward importers to demonstrate that goods from flagged regions were not made with forced labor, a standard that demands documented, auditable due diligence rather than supplier assurances. The practical response is to invest now in traceability, to identify exposure to higher-risk regions and commodities, and to build documentation that can satisfy customs authorities in either country.
Firms that treat forced-labor compliance as a core operational discipline rather than an afterthought will be better positioned as both governments tighten enforcement. That means designating clear ownership of supply-chain due diligence, auditing suppliers against recognized standards, and retaining the records needed to respond quickly to a border hold or a request for proof of origin. The cost of building those systems is real, but it is likely to be smaller than the cost of a detained shipment or a lost customer.
Outlook
For Canadian businesses, the near-term takeaway is reassuringly narrow but strategically significant. The immediate cost of the forced-labor duty is small, thanks to the CUSMA exemption and the lower rate. The lasting lesson is that compliance expectations are rising on both sides of the border, and that a measure introduced as a bargaining chip can harden into a permanent fixture once anchored in a durable legal authority. Firms that read the signal early and invest in supply-chain transparency will face fewer surprises than those that wait for enforcement to arrive at their door.
The forced-labor tariff is, for now, more a marker of direction than a decisive economic blow to Canada. Its lower rate and CUSMA exemption reflect Ottawa’s partial success in making its case, even as Washington pressed ahead. The more consequential contests lie just ahead: the separate 50 percent threat scheduled for August 19, the still-unresolved sectoral duties, and the larger question of whether the two countries can agree on a renewed continental trade framework. LeBlanc’s promise of continued “constructive” engagement suggests Ottawa will keep arguing that its record on forced labor leaves “no basis” for the new duty, even as it prepares for the tougher fights to come.
