Trump Implements 10% Global Tariff After Supreme Court Blocks Prior Authority

Administration pivots to 1974 Trade Act following high court ruling limiting tariff power under emergency statute.

The Trump administration on Tuesday began enforcing a global 10 percent tariff on imported goods after the Supreme Court ruled that President Donald Trump lacked authority to impose similar tariffs under the International Emergency Economic Powers Act.

The new tariff went into effect Tuesday, according to a notice issued by U.S. Customs and Border Protection. The measure applies broadly, with only limited exceptions identified in the implementation guidance.

The Supreme Court last week determined that the International Emergency Economic Powers Act (IEEPA) does not grant the president authority to impose tariffs. The justices did not rule on whether other statutory authorities could permit such action.

Following the decision, Trump said he would pursue alternative legal grounds to reestablish a global tariff framework. In remarks responding to the ruling, he announced plans to invoke Section 122 of the Trade Act of 1974 to implement the new 10 percent duty.

Trump has also cautioned foreign governments against using the court decision to gain leverage in trade negotiations with the United States.

“Any Country that wants to ‘play games’ with the ridiculous supreme court decision, especially those that have ‘Ripped Off’ the U.S.A. for years, and even decades, will be met with a much higher Tariff, and worse, than that which they just recently agreed to,” he wrote in a post on Truth Social. “BUYER BEWARE!!! Thank you for your attention to this matter.”

The administration has not released a detailed timeline for additional tariff adjustments but has indicated that trade negotiations remain ongoing. Officials have also suggested that further measures could follow if trading partners attempt to renegotiate terms in response to the court’s decision.

The 10 percent tariff now in force represents the administration’s latest move in a broader strategy aimed at reshaping trade relationships and addressing longstanding disputes over market access and trade imbalances.
