Customs

US President Donald Trump had said earlier he wanted to increase the expected customs duties on a wide range of American imports by much higher than 2.5%.

“I put on my mind what it will be, but I haven’t decided it yet, but it will be enough to protect our country,” Trump told reporters.
In response to a question about a report saying that the Secretary of the Treasury appointed Scott Besent prefers to start imposing general fees on American imports by 2.5%, Trump said he does not believe that Pesent supports this and he himself will not prefer him, adding that he wants a much higher fees than 2.5%.
