President Trump is adding a new 10 percent tariff on nearly all imports to the United States, following a Supreme Court ruling that overturned most of the levies imposed by the US government last year.

In an executive order signed Friday evening, Trump outlined a few exceptions, including imports of critical minerals, beef and fruits, cars, pharmaceuticals, and products from Canada or Mexico. The new tariffs will take effect on February 24, 2026.

In a press conference Friday afternoon, Trump was fired up about the Supreme Court decision and resorted to personal attacks, calling the six justices who ruled against his trade policies “a disgrace to our nation.” Answering a reporter’s question about how two of the justices he nominated, Neil Gorsuch and Amy Coney Barrett, voted for the overturn, Trump called them “an embarrassment to their families.”

The new trade policy is based on Section 122 of the Trade Act of 1974, which allows the president to single-handedly and immediately charge tariffs of up to 15 percent if there are “large and serious” trade deficits. These tariffs only last 150 days unless Congress authorizes an extension. Like the International Emergency Economic Powers Act (IEEPA), the statute has never before been used by a US president in this way.

Once the 150-day deadline arrives, it’s possible for Trump to keep reissuing Section 122 tariffs. But the administration could also use this time to prepare other forms of tariffs, essentially switching legal justifications to get the same regulatory effects, says Gregory Husisian, a partner and litigation attorney at Foley & Lardner LLP, which has helped over a hundred companies file requests for tariff refunds. “[Section 122 tariff] is for a limited time period, so it's going to be a bridge authority,” Husisian says.
