Trump says he will raise US global tariff rate from 10% to 15%

President Donald Trump said on Saturday he will raise from 10% to 15% a temporary tariff rate on U.S. imports from all countries, which he imposed after the U.S. Supreme Court ruled against his signature tariff program based on an economic emergency law.

Infuriated by the high court's ruling, Trump on Friday ordered an immediate 10% tariff on all imports, in addition to any existing tariffs. The law allows him to impose a levy of up to 15% for 150 days, although it could face legal challenges, reports Reuters.

During that period, his administration will work on issuing new and "legally permissible" tariffs, he said.

"I, as President of the United States of America, will be, effective immediately, raising the 10% Worldwide Tariff on Countries, many of which have been 'ripping' the U.S. off for decades, without retribution (until I came along!), to the fully allowed, and legally tested, 15% level," he wrote in a Truth Social post.
