President Trump said he would increase to 15% from 10% a global tariff that will replace many of the duties ruled illegal by the Supreme Court

This move, announced via Truth Social, invokes Section 122 of the Trade Act of 1974, allowing tariffs up to 15 percent for a maximum of 150 days to address balance-of-payment deficits. This is the first time a president has invoked this section, and by immediately increasing the rate from 10 percent to 15 percent, Trump has maximized the authority available under the statute.

The Supreme Court's 6-3 opinion rejected the administration's initial method of implementing tariffs under the International Emergency Economics Powers Act. While Trump claims the court approved his use of Section 122, the court's majority opinion stated it was not ruling on the legality of deploying such powers.

The administration has plans ready for further tariff actions if needed.
