US President Donald Trump will put in place 25% tariffs on imports from Canada and Mexico and 10% tariffs on goods from China effective on Saturday, the White House said.
But it provided no word on whether there would be any exemptions to the measures that could result in swift price increases to US consumers.
Mr Trump, a Republican, had been threatening the tariffs to ensure greater co-operation from the countries on stopping illegal immigration and the smuggling of chemicals used for fentanyl, but he has also pledged to use tariffs to boost domestic manufacturing.
“Starting tomorrow, those tariffs will be in place,” White House press secretary Karoline Leavitt told reporters.
“These are promises made and promises kept by the president.”
Mr Trump had said he was weighing issuing an exemption for Canadian and Mexican oil imports, but Ms Leavitt said she had no information to share on the president’s decision on any potential carveouts.
The United States imported almost 4.6 million barrels of oil daily from Canada in October and 563,000 barrels from Mexico, according to the Energy Information Administration.
US daily production during that month averaged nearly 13.5 million barrels a day.
Mr Trump has previously stated a 10% tariff on Chinese imports would be on top of other import taxes charged on products from the country.
