The letters listed a range of tariffs. Goods entering the U.S. from Japan, South Korea, Malaysia, Kazakhstan, and Tunisia will be subject to a 25 percent levy. There will be a 30 percent levy on South African and Bosnian goods, while imports from Indonesia will be subject to a 32 percent rate.

A day ahead of the expiry of the 90-day tariff pause, Trump said, the USA could have been much harsher and could have gone much higher with tariffs.

President Donald Trump unveiled a wave of letters again threatening key trading partners with high tariff rates even as he delayed the increased duties until Aug. 1 and suggested that he was still open to negotiations.
