The Trump Administration announced a fresh set of tariffs that target a range of Canadian products, sparking concern among firms that rely on cross‑border trade. The proposal, described as the first use of Section 338 of the Tariff Act of 1930, would affect items such as automobiles, dairy, alcohol, fishing rods and even wigs, with the rates slated to begin on Aug. 19.
Scope and immediate impact
According to the filing, the tariff list covers roughly $20 billion in annual Canadian exports. By comparison, total U.S. imports from Canada reached $382 billion in 2025, meaning the new duties would touch about five percent of that flow. Oil and natural gas are explicitly exempt, leaving most energy‑related shipments untouched.
Companies named as potentially affected include dairy producer Agropur, plant‑based brand Daiya and ice‑cream maker Halo Top. Some firms, however, claim they fall outside the scope. A spokesperson for Toronto‑based frozen pizza brand Porta says its finished products, which contain dairy, do not match the categories listed in the announcement.

Legal and political backdrop
Last year’s tariff rounds were deemed unconstitutional, prompting the administration to invoke Section 338 as a response to what it calls discriminatory Canadian trade practices. The law allows a president to levy duties of up to 50 percent on countries that treat U.S. goods unfairly. Officials point to recent Canadian boycotts of American products as the trigger for this action.
Experts note that Section 338 has never before been used to impose such tariffs. Jackson Wood, director of industry strategy for global trade intelligence at Descartes, explains that the USMCA agreement expired on July 1, creating a “rolling one‑year period” that leaves room for new measures. He adds that the 50 percent ceiling sounds more alarming than the reality, given the limited share of trade involved.
While the tariffs could theoretically reach the maximum rate, the actual effect may be muted. Wood observes that small and medium‑sized businesses, such as independent spirit makers or cheese producers, are likely to feel the brunt more than large multinational firms. “The dairy industry in Canada has long been a sore spot for the U.S., particularly its powerful dairy farming community,” he said.
In the middle of these negotiations, it seems reasonable to expect that both governments will seek a compromise that eases pressure on vulnerable sectors. If talks progress, the headline‑grabbing 50 percent figure could be scaled back, allowing affected companies to adjust without drastic supply‑chain overhauls. That outcome would align with the broader trade relationship, which has historically weathered periodic disputes.

Importers remain cautious.
Joseph Firrincieli, sales manager at OEC Group New York, told a retail outlet that many have become “kind of numb” after last year’s surprise tariffs. He notes that his Canadian clients have not yet altered shipment plans, emphasizing a “wait and see” stance until the rules are finalized.
Negotiations are expected to continue over the next few weeks, and the final rates could differ from the initial announcement. For now, the proposed duties remain provisional, with the administration signaling that they will be enforced only if they survive legal scrutiny. Companies awaiting clarification are advised to monitor official updates and prepare contingency plans, though many anticipate that the overall impact on bilateral trade will stay modest.
