The U.S. Supreme Court recently declared illegal the tariffs that former President Donald Trump imposed on Argentina during what was dubbed "Liberation Day" on April 2, which included a 10% additional tariff imposed under the International Emergency Economic Powers Act (IEEPA). This ruling calls into question the future of the U.S.-Argentina Reciprocal Trade and Investment Agreement (ARTI), which aimed to reduce tariffs significantly as part of its core commitment. The Court's decision hinges on the interpretation that the tariffs were improperly applied, as they did not constitute a national emergency as originally claimed by the Trump administration.

The invalidation of these tariffs presents a significant development in the trade relationship between the U.S. and Argentina. According to the ruling, the 10% tariff previously imposed on Argentina is not only illegal but also undermines the primary benefit previously granted to Argentina under the ARTI agreement—namely, the promise to reduce certain tariffs from 10% to 0% on numerous goods. This change stands to impact Argentine exports and the overall economic landscape, as tariffs are crucial in determining market access for exporters.

As discussions arise regarding the implications of the Supreme Court's decision, various stakeholders in Argentina are likely to seek clarity on how this ruling may reshape existing trade agreements and improve access to the U.S. market. The verdict could lead to negotiations aimed at reinstating a more favorable trade environment that may boost Argentina's economy by revitalizing its export sector and increasing mutual trade opportunities with the United States.
