Trump Imposes 10% Global Tariff After Supreme Court Strikes Down Previous Duties

U.S. President Donald Trump on Friday announced he would impose a 10% global tariff for 150 days, replacing some emergency duties that the Supreme Court recently struck down. The new tariffs, set to take effect in about three days, will be applied on top of existing duties.

Trump said the move is authorized under Section 122 of the Trade Act of 1974, which allows the president to impose duties of up to 15% for up to 150 days on countries experiencing “large and serious” balance of payments issues. Unlike other trade laws, the statute does not require prior investigations or impose procedural limits.

The announcement follows the Supreme Court ruling that declared Trump’s previous broad global tariffs under the International Emergency Economic Powers Act (IEEPA) illegal, stating that he had overstepped his authority.

“We have alternatives, great alternatives,” Trump said, adding that the tariffs could generate more revenue and strengthen the U.S. economy.

In addition to Section 122 tariffs, the administration is initiating several Section 301 investigations targeting unfair trade practices by foreign countries and companies.

While Section 122 tariffs take effect immediately for 150 days, Section 301 investigations typically take months to complete.
