Tariffs will revert back to their April 2 rates on Aug. 1 for countries that fail to nail down new trade deals with the United States, Treasury Secretary Scott Bessent said Sunday, just three days before the Trump administration’s initial July 9 deadline for tariffs to return.

Donald Trump has said he will impose 25 per cent tariffs on imports of goods from Japan and South Korea, in an announcement that sent US stocks sliding. The president on Monday said the new levies on both countries would come into effect on August 1.
