President Donald Trump announced a new 10% “global tariff” on imports on Friday. He spoke just hours after the Supreme Court of the United States struck down key parts of his previous tariff strategy.

Trump said he will sign an executive order to impose the tariff under Section 122 of the Trade Act of 1974. This law allows a temporary import duty for up to 150 days. He said the tariff will apply to all trading partners. Furthermore, it will be on top of existing duties already in place.

He slammed the court’s decision as “deeply disappointing” and criticised some justices by name. Trump said the ruling weakens U.S. trade power and harms the economy. He also promised to use other legal tools if needed.

Earlier on Friday, the Supreme Court ruled 6-3 that Trump had exceeded his authority by using emergency powers to impose sweeping tariffs under the 1977 International Emergency Economic Powers Act. The court said that law does not give the president power to impose broad tariffs without Congress.

Despite the setback, Trump said all current tariffs under other laws — including those targeting national security or unfair trade practices — will remain in effect. He then vowed to continue fighting for tougher trade policies.

The Section 122 tariff plan is intended to keep some duties in place while the administration explores other options. However, economists note that these tariffs are temporary and limited in scope compared with the previous measures.

Trump also said he plans to launch investigations under Section 301 of the Trade Act. These actions could lead to further tariffs if foreign trade practices are found to be unfair.

Many trading partners and markets are watching closely. Critics warn that higher tariffs could raise costs for U.S. consumers and businesses. Meanwhile, Trump maintains the tariffs will protect American industry and improve the economy.

The new global tariff marks a bold shift in U.S. trade policy after the Supreme Court defeat. And Trump insists his trade agenda will continue despite legal obstacles.
