According to the United States Trade Representative’s office, the Trump administration announced new 10 and 12.5 per cent tariffs on more than 60 nations on Thursday, citing forced labour in global supply chains. The duties, which target countries including Canada, Mexico, and the United Kingdom, were unveiled just hours before a previous temporary tariff tool was set to expire.
Section 301 Investigations Target Global Supply Chains
The new duties stem from trade investigations launched earlier this year through Section 301 of the Trade Act of 1974. According to the United States Trade Representative’s office, the action follows a U.S. Supreme Court decision that struck down the tariff tool previously used for “Liberation Day” and fentanyl-related duties.
To temporarily replace those measures, U.S. President Donald Trump utilized Section 122 of the Trade Act of 1974 to enact a 10 per cent global duty. That statute, however, faced a Friday expiration date unless extended by Congress. Experts have noted that the Section 301 forced labour investigations provide a more permanent mechanism to rebuild the U.S. tariff wall, according to published reports.
“President Trump recognizes that decades of moral suasion have not eradicated forced labour from global supply chains,” United States Trade Representative Jamieson Greer said in a news release. “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.”
Did You Know? The United States has maintained a forced labour import ban for nearly a century, yet trade officials argue that international enforcement remains inconsistent among key trading partners.
Exemptions Spark Relief for North American Trade
While dozens of nations face the new levies, the administration carved out specific exemptions. According to the federal register’s notice, which includes hundreds of pages of individual exemptions, products such as oil, gas, and fertilizer are spared from the duties.
Additionally, products that qualify for duty-free status under the United States-Mexico-Canada Agreement (USMCA)—the trade pact negotiated by Trump during his first term—remain untouched by the latest announcement. Canada, Mexico, and the U.K. are facing the 10 per cent tariff tier, while other nations are hit with a 12.5 per cent levy.
Canada Disputes Tariff Justification Over Forced Labour Compliance
The U.S. trade office report released Thursday stated “that Canada has failed to effectively enforce its forced labour import prohibition.” In response, the Canadian government previously argued that new domestic legislation combating forced labour should exempt the country from additional U.S. tariffs.

Canada already enforces supply chain transparency laws requiring annual federal reports, and tabled Bill C-35 last month to enhance enforcement capabilities. According to government details, the proposed bill establishes a public registry of products linked to forced labour in specific regions using intelligence from embassies and other authorities, placing the burden on importers to prove goods were not produced through slavery.
In a written submission to Greer’s office earlier this month, the Canadian government asserted 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.”
