WASHINGTON (MNN); US President Donald Trump announced on Saturday that he is increasing worldwide tariffs on goods entering the United States from 10 per cent to 15 per cent, effective immediately, just a day after the Supreme Court curtailed his earlier tariff measures.
Following the court’s ruling on Friday, Trump had imposed a flat 10 per cent tariff across all imports. The decision by the Supreme Court of the United States found that the president had overstepped his authority by introducing a range of higher duties under an emergency economic law.
The newly announced tariffs are based on Section 122, a separate legal provision that permits duties of up to 15 per cent but requires congressional approval if they are to remain in place beyond 150 days.
In a post on his Truth Social platform, Trump criticized what he described as an “extraordinarily anti-American decision” by the court and said the administration would raise tariffs to the maximum legally permitted 15 per cent level.
He added that over the coming months, his administration would determine and implement new, legally sustainable tariffs as part of what he called a continued effort to strengthen the US economy under his “Make America Great Again” agenda.
On Friday, the Supreme Court, which has a conservative majority, ruled that the International Emergency Economic Powers Act does not grant the president authority to impose tariffs. The ruling marked Trump’s most significant judicial setback since returning to office last year.
Canada welcomed the decision, stating that the tariffs had always been unjustified. Meanwhile, other key US trading partners, including the United Kingdom, Germany and the European Union, responded cautiously, saying they were reviewing the court’s decision and maintaining contact with the Trump administration.
Tariffs have been a central element of Trump’s economic and foreign policy strategy, forming the backbone of a global trade dispute that intensified after he began his second term. The measures have strained relations with trading partners, unsettled financial markets and contributed to global economic uncertainty.
The administration had projected that the tariffs would generate trillions of dollars in revenue for the United States over the next decade. However, no official tariff collection data has been released since December 14, 2025.
