U.S. President Donald Trump's new global tariffs have taken effect at ten percent, rather than the 15 percent he announced over the weekend, after the U.S. Supreme Court struck down the sweeping global tariffs he imposed last year using the 1977 International Emergency Economic Powers Act(IEEPA).

The temporary ten percent tariff took effect at 2:01 p.m. Tuesday, Korean Standard Time, on all imports to the U.S. with some exceptions as stipulated under an executive order signed by Trump on Friday in Washington.

Trump announced on social media the following day that he would increase the import duty to 15 percent, though he did not specify when he would do so.

The new tariffs do not apply to certain raw materials necessary for American industries, products subject to sector-specific tariffs, or others that could incite inflation in the U.S.

The tariffs are expected to remain in effect until July 24 in accordance with Section 122 of the 1974 Trade Act, which allows the president to impose the charge for 150 days without congressional approval.
