The Supreme Court of the United States declared unlawful the tariffs imposed through emergency procedures, after which Trump immediately introduced new tariffs of 10 percent on nearly all goods imported into the country - instead of the announced 15 percent.

The US Customs and Border Protection (CBP) announced that, with the exception of exempt products, imports "will be subject to an additional ad valorem rate of 10 percent." This measure has caused confusion among trade partners, particularly due to the lack of clarity on why a lower rate than announced was applied.

Trump reacted sharply to the court ruling, stating that the Supreme Court decision was "unfortunate" but that he has alternative legal mechanisms with which he can act "much more powerfully and radically." He simultaneously threatened: "If anyone wants to play with this absurd court decision, especially those who have been robbing us for a long time - they will face even higher tariffs."

The European Bank for Reconstruction and Development meanwhile revised upward its growth forecast for 2026, assessing that the real impact of American tariffs is significantly less than expected.

Secretary of State Marco Rubio was expected to brief leading members of Congress on trade policy, and President Trump suggested he may also introduce new licensing fees for trade partners.

The situation has deepened uncertainty among American trade partners, and the new trade regime will have a direct impact on developing countries that direct a significant portion of their exports toward the American market.
