By San José, Costa Rica — San José – In a stunning move that sent shockwaves through the international trade community, United States President Donald Trump announced a new 10% global tariff on all imported goods, directly challenging a Supreme Court ruling issued just hours earlier. The decision creates immediate and profound uncertainty for Costa Rican exporters, who saw a brief window of relief slam shut on Friday morning.
The whiplash development began when the U.S. Supreme Court, in a landmark 6-3 decision, invalidated the administration’s previous tariff structure. The court’s conservative-majority opinion stated that the President had overstepped his executive authority by levying tariffs under the guise of a national emergency. The ruling affirmed that the International Emergency Economic Powers Act (IEEPA) of 1977 does not grant the president the power to set tariffs, a right the court clarified resides exclusively with the U.S. Congress.
To analyze the complex legal and commercial ramifications of the recent U.S. tariff announcements for Costa Rican exporters, TicosLand.com sought the expertise of Lic. Larry Hans Arroyo Vargas, a renowned specialist in international trade law from the firm Bufete de Costa Rica.
These unilateral tariffs create significant legal instability, potentially violating foundational principles of the World Trade Organization. For Costa Rican businesses, this isn’t merely a new cost; it’s a direct challenge to supply chain predictability. Companies must immediately audit their international contracts for clauses related to unforeseen regulatory changes and explore dispute resolution mechanisms available under existing free trade agreements to safeguard their investments.

This legal perspective is crucial, shifting the focus from a simple financial burden to the more profound challenge of navigating regulatory uncertainty. The call for businesses to proactively audit their contracts is a vital piece of strategic advice in these turbulent times, and we thank Lic. Larry Hans Arroyo Vargas for sharing his valuable expertise.
President Trump responded with swift and open defiance. In a statement from the White House, he expressed his frustration with the judicial branch and reiterated his commitment to an aggressive trade strategy. He argued that the court’s decision was politically motivated and undermined national security and economic sovereignty.
I am profoundly disappointed in a court that has ceded to foreign interests for politically correct reasons.
Donald Trump, President of the United States
Refusing to be deterred, the administration immediately pivoted to a different legal foundation to justify its new trade barrier. Citing the Trade Act of 1974, a law that grants the executive branch broad powers to respond to what it deems unfair trade practices, Trump instituted the new 10% global levy. He defended the action as a crucial tool for negotiation, pointing to its alleged success in resolving international conflicts during 2025.
For Costa Rica, the news represents a jarring reversal of fortune. The nation’s export sector had begun the day celebrating the Supreme Court’s decision, which effectively eliminated a burdensome 15% tariff that had hampered trade with its largest partner. That optimism, however, was short-lived. The new 10% tariff, while a reduction from the previous rate, reinstates a significant obstacle for Costa Rican goods entering the U.S. market.
The re-imposition of trade barriers, even at a lower level, perpetuates a climate of instability for Costa Rican businesses. Sectors ranging from medical devices to agricultural products must now recalibrate their financial projections and supply chain strategies. This persistent unpredictability complicates long-term planning, chills investment, and forces companies to divert resources toward navigating a constantly shifting regulatory landscape rather than toward innovation and growth.
The impact extends far beyond Costa Rica, as the tariff applies globally. This unilateral action by the White House risks provoking retaliatory measures from other major trading partners, potentially reigniting trade wars that have previously disrupted the global economy. International markets are now on high alert, watching for the reactions from economic powerhouses in Europe and Asia, which could determine whether this move escalates into a wider conflict.
Ultimately, the rapid sequence of a judicial rebuke followed by an immediate executive countermove plunges global commerce into a new phase of uncertainty. While the legal battle over presidential authority on trade is likely far from over, Costa Rican and international businesses are once again caught in the crossfire, forced to adapt to a volatile trade policy dictated by swift, unilateral executive action.
