New US tariff starts at 10%, Trump administration working to hike it to 15%

The United States began collecting a temporary new 10% global import tariff on Tuesday, but the Trump administration was working to increase it to 15%, a White House official said, sowing confusion over President Donald Trump's tariff policies after last week's Supreme Court defeat.

Trump initially signed an order on Friday for a 10% tariff to last 150 days to replace broad duties under an emergency law that were struck down by the Supreme Court, but on Saturday, he said he would increase the rate to 15%.

On Monday night, before the midnight start of collections, the U.S. Customs and Border Protection agency notified shippers that the rate would be 10%.

The White House official told Reuters that Trump has had "no change of heart" in his desire for a 15% tariff under Section 122 of the Trade Act of 1974, but offered no details on the timing for that increase.
