President Donald Trump plans to impose tariffs on Canada and Mexico starting Tuesday, March 4, in addition to doubling the 10% universal tariff charged on imports from China, reported the Associated Press.

In early February, Trump announced 25% levies on Canadian and Mexican merchandise and then delayed them by one month after discussions with the heads of those countries. However, in a Truth Social post Thursday, Trump announced that the tariffs were back on.

The new 10% tax on Chinese goods that he declared Thursday is in addition to a 10% levy that took effect in early February, wrote the Washington Post. The latest action will “bring the total import fee on some Chinese goods to 45%.”

According to the Post, while talks continue with Canadian and Mexican diplomats, a White House official reiterated that Trump is set on imposing the new import taxes.

“This is locked in,” said the official, speaking on the condition of anonymity.

In Canada, Prime Minister Justin Trudeau has “vowed to impose retaliatory tariffs on up to $107 billion worth of U.S. goods, including Florida orange juice, Kentucky bourbon and Pennsylvania motorcycles,” according to the Post. Other measures, including taxes or limitations on Canadian energy exports to the United States are also possible, the Canadian government has said.

Along with the tariffs Trump confirmed Thursday, new import taxes on steel and aluminum are scheduled to take effect March 12, wrote the Post.

NACS and others in the fuel supply chain have been working to mitigate the impact of tariffs on the U.S. fueling industry. In a January letter to the White House, NACS, along with other associations, wrote: “[We] write to express our deep concern with the potential imposition of tariffs on crude oil and other imported petroleum products, the international trade of which is critical to domestic affordability, security and growth.”
