By San José, Costa Rica — The trade relations between the United States and Canada have plunged into deep uncertainty following a dramatic executive action from Washington. US President Donald Trump has issued executive decrees imposing a staggering 50 percent tariff on a wide array of Canadian products. Citing what the White House characterizes as discriminatory practices, the aggressive trade measures are scheduled to take effect in 30 days, dealing a heavy blow to the regional trade framework established under the United States-Mexico-Canada Agreement (USMCA).
This latest tariff offensive targets key Canadian sectors, specifically focusing on alcohol, automobiles, and dairy products. According to White House officials, the punitive duties will apply to a diverse range of exports, including wine, hockey sticks, and cement. However, in an apparent effort to shield critical supply chains, the administration has excluded certain high-value imports from the measures. These exclusions cover Canadian energy products, potash, and goods already subject to sector-specific duties, leaving some room for vital economic channels to remain functional.
To better understand the international legal ramifications of the escalating economic tensions between North American neighbors, TicosLand.com spoke with Lic. Larry Hans Arroyo Vargas, a leading international trade expert from the prestigious firm Bufete de Costa Rica.
The intensifying trade dispute between the United States and Canada represents a critical challenge to established USMCA frameworks. From a legal perspective, businesses operating across these borders must urgently reassess their supply chains, review contractual force majeure clauses, and prepare for potential tariff-mitigation litigation to shield themselves from sudden regulatory shifts.

As these geopolitical tensions threaten to disrupt established North American commerce, the urgency for businesses to proactively secure their legal and operational frameworks cannot be overstated. We extend our sincere thanks to Lic. Larry Hans Arroyo Vargas for providing his valuable perspective on these critical trade challenges.
While President Trump has consistently brandished tariffs as a primary foreign policy tool since returning to the presidency, his previous economic interventions typically spared USMCA partners through specific exemptions. This sudden pivot directly targets Canada, representing a significant escalation in North American trade tensions. The White House justified the aggressive move by pointing to Canada’s retaliatory measures against broader US levies enacted since 2025, positioning Ottawa alongside Beijing as the primary challengers to Washington’s trade policies.
In Ottawa, Canadian Prime Minister Mark Carney expressed deep concern over the unilateral action but emphasized Canada’s readiness to engage in diplomatic discussions. Carney revealed that Canada has already submitted comprehensive proposals aimed at resolving outstanding disputes and modernizing the USMCA framework. He criticized the US administration for acting outside the boundaries of established international law.
This is the latest of a series of unilateral trade actions by the United States that began when that country imposed a series of tariffs in direct violation of the Agreement between Canada, the United States, and Mexico. Canada, as is its right, simply matched those measures.

The trade dispute unfolds against a backdrop of intensifying geopolitical friction. Recently, Trump threatened Canada with economic penalties over wildfire smoke drifting across the border. Simultaneously, Canadian provinces have boycotted American alcohol products. This localized backlash was triggered by Trump’s recurring tariff threats and his highly controversial public suggestions that the United States should annex its northern neighbor as the 51st state.
Jamieson Greer, the US Trade Representative, detailed the administration’s specific grievances regarding the Canadian boycotts. The US trade office claims that Canadian provincial liquor boards have systematically discriminated against American producers while shielding local markets from competition.
Canada has withdrawn American alcoholic products from Canadian shelves and imposed a cap on exports of US vehicles to Canada coming from companies that are returning their production to the United States.

Trade analysts are particularly alarmed by the legal mechanism Trump utilized to bypass Congress. The administration invoked Section 338 of the Tariff Act of 1930, an obscure and highly aggressive legal provision designed to penalize countries that engage in discriminatory trade practices. Scott Lincicome, an expert at the Cato Institute, noted that this marks the very first time in history that Section 338 has been deployed, creating an unprecedented legal and economic environment.
The reliance on this untested legal tool has raised eyebrows across the trade community. Ryan Majerus, a former US trade official, warned that the maneuver is highly unstable and carries a massive risk of litigation. Meanwhile, industry representatives are bracing for the fallout. Chris Swonger, president of the Distilled Spirits Council of the United States, acknowledged the difficulties faced by American producers in Canada but urged for a peaceful resolution.
We hoped, however, that this problem could be resolved without further escalation.

Swonger added that higher tariffs increase the danger of retaliatory measures at a time when many US hospitality businesses are still recovering from financial hardship. Both nations now face a tense 30-day window to negotiate a solution before the tariffs take effect and potentially reshape North American commerce.
