Just this morning Singapore time, U.S. President Donald Trump said that the 50% tariff on copper imports, which he announced earlier on Tuesday, will begin on Aug. 1.

On Wednesday, Trump posted a fresh slate of tariff letters on goods from at least seven more countries, including Mexico, the no. 1 importer of goods to the U.S., Philippines, Brunei and Sri Lanka.

The 50% tariff on Brazil marks the largest duties rate that the White House has imposed on its trading partners in the recent round of new levies, which are set to begin on Aug. 1.
