The wave of announcements came as the clock ticked down toward an August 1 deadline for higher tariff rates to kick in on goods imported from most of the world as Trump presses on with his bid to reshape global trade. The president also touted what he said was a deal with South Korea that would include a 15% U.S. tariff on imports from the country.

Details of the levy, though, fell short of the sweeping restrictions expected and left out copper input materials such as ores, concentrates and cathodes. The surprise move dragged down U.S. copper prices more than 17% on the Comex exchange and unwound a premium over the London global benchmark that had grown in recent weeks, with shipments diverted there in anticipation of higher domestic prices.

"Someone must have finally got through to (Trump) that the U.S. economy simply can't afford this new trade-hit." Trump first teased the copper tariff in early July, implying that it would apply to all types of the red metal, ranging from cathodes produced by mines and smelters to wiring and other finished products. Yet the proclamation released by the White House said the tariff will apply only to pipes, tubes and other semi-finished copper products, as well as products that copper is heavily used to manufacture, including cable and electrical components. The move aids manufacturers, but does little to boost the constrained U.S. copper mining industry, which for years has asked Washington for permitting reform or other steps that could fuel growth. The move is essentially a boost for Chile and Peru, two of the world's largest copper miners and major suppliers to the United States.

Trump on Wednesday slapped a 50% tariff on most Brazilian goods to fight what he has called a "witch hunt" against former President Jair Bolsonaro, but softened the blow by excluding sectors such as aircraft, energy and orange juice from the heavier levies. That came as a relief for many in Brasilia, who since Trump announced the tariffs had been urging protections for major exporters caught in the crossfire.

"We're not facing the worst-case scenario," Brazilian Treasury Secretary Rogerio Ceron told reporters. "It's a more benign outcome than it could have been." The new tariffs will go into effect on August 6, not August 1 as Trump announced originally. 'DE MINIMIS' The White House also said the United States is suspending a "de minimis" exemption that allowed low-value commercial shipments to be shipped to the United States without facing tariffs. Under Trump's order, packages valued at or under $800 sent to the U.S. outside of the international postal network will now face "all applicable duties" starting on August 29, the White House said. Trump earlier targeted packages from China and Hong Kong. The tax-and-spending bill recently signed by Trump repealed the legal basis for the de minimis exemption worldwide starting on July 1, 2027. "Trump is acting more quickly to suspend the de minimis exemption than the OBBBA requires, to deal with national emergencies and save American lives and businesses now," the White House said, referring to the bill known as the One Big Beautiful Bill Act. Goods shipped through the postal system will face one of two tariffs: either an "ad valorem duty" equal to the effective tariff rate of the package's country of origin or, for six months, a specific tariff of $80 to $200 depending on the country of origin's tariff rate. SOUTH KOREA Trump said late on Wednesday that he had settled on a 15% U.S. tariff on imports from South Korea as part of an agreement with the Asian trading partner that avoids even higher levies. As part of the arrangement, South Korea would invest $350 billion in the United States in projects selected by Trump and purchase $100 billion of liquefied natural gas and other energy products, the U.S. president said. The South Korean government could not immediately be reached for comment. Reuters has not verified the terms of a deal, and it was not immediately clear how the investment deals would be structured or over what timeframe.
