The back-and-forth underscores the uncertainty of Trump's tariffs, which is once again causing confusion with markets, trading partners and businesses large and small.
Donald Trump's reworked global tariffs began Tuesday at a rate of 10%, even though he said over the weekend that they would start at 15%.
On Friday, after the Supreme Court struck down most of Trump's tariff agenda, he announced that he would quickly implement a 10% flat tariff for all trading partners using a different trade law.
One day later, Trump posted on Truth Social that "effective immediately" he would be "raising the 10% Worldwide Tariff ... to the fully allowed, and legally tested, 15% level."
Under the trade law the administration is now turning to, called Section 122, tariffs of up to 15% can be quickly applied, but only for up to 150 days.
