U.S. President Donald Trump's new global trade tariffs officially took effect at a 10% rate on Tuesday, following a Supreme Court decision invalidating his broader levies. The lower 10% level, communicated via U.S. Customs and Border Protection, replaces the 15% tariff Trump initially announced after the ruling. The 10% levy applies to all imports unless exempt and will last 150 days, until July 24, 2026.

Trump must seek Congressional approval thereafter to maintain the tariffs. This development follows the court's rejection of Trump's use of emergency powers under the International Emergency Economic Powers Act for tariffs. The ruling also leaves unresolved the question of the $160 billion in tariff revenue collected, prompting lawsuits like FedEx's seeking refunds.

Companies like FedEx are challenging the legality of the duties paid under Trump's now-invalid tariffs.
