Trump Boosts New Global Tariff to 15% After Court Setback
The rate, up from the 10% level the president announced a day earlier, is on temporary duties that will replace many of the levies ruled illegal by the Supreme Court
- President Trump increased a global tariff to 15% from 10%, effective immediately, following a Supreme Court ruling.
- The Supreme Court overturned most of President Trump’s second-term tariffs.
- The 15% tariff is authorized for 150 days Section 122 of the Trade Act of 1974, with plans for more permanent levies later.
WASHINGTON—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.
In a social-media post on Saturday, the president said the new 15% global tariff would take effect immediately. He said his decision to increase the tariff rate was the result of a “thorough, detailed, and complete review of the ridiculous, poorly written, and extraordinarily anti-American” Supreme Court ruling.
The announcement came a day after the Supreme Court overturned most of Trump’s second-term tariffs, rejecting the administration’s argument that a 1977 law, the International Emergency Economic Powers Act, implicitly authorized the tariffs. Trump denounced the ruling and immediately reinstated a 10% global tariff under a different authority—Section 122 of the Trade Act of 1974.
Section 122 allows for tariffs of up to 15% for 150 days. After that period, Trump has said that those levies will be replaced with a longer-lasting tariff authority—Section 301 of the Trade Act. That provision would allow for more permanent levies, but requires monthslong investigations before tariffs can be imposed, which Trump hinted at in his Saturday post.
“During the next short number of months, the Trump Administration will determine and issue the new and legally permissible Tariffs, which will continue our extraordinarily successful process of Making America Great Again,” Trump posted.
