Mexico faces a 25% tariff, according to the White House, which said it will remain in place until the country “cooperates with the U.S. in the fight against drugs.”

Canada is also getting hit with a 25% tariff, though imports of its energy products will carry a 10% duty, as the White House called for cooperation on drug trafficking and border security.

And Trump slapped a 10% tariff on China, conditioning it on full cooperation in the fight against fentanyl.

The tariffs will go into effect at 12:01 a.m. Eastern Time on Tuesday.

There will be no exceptions to the tariffs, and even a loophole that allows small shipments from Canada to enter duty free will be suspended, impacting e-commerce.

While Trump’s executive orders say tariffs could rise in the event of retaliation, Canadian Prime Minister Justin Trudeau will impose a 25% tariff on $20 billion of US goods on Tuesday, followed by another $85 billion of goods three weeks later. The targeted products include vegetables, appliances, and furniture.

Mexican President Claudia Sheinbaum also said her country would retaliate with tariffs, while China’s commerce ministry said it would file a complaint with the World Trade Organization and take “corresponding countermeasures.”

The lighter US tariff on Canadian energy, which presumably would include crude oil, refined products, and electricity, also suggests the White House seeks to avoid making Americans pay more for fuel and stoking inflation.

Canada accounts for about 60% of US oil imports. Some US refineries, especially in the Midwest, rely heavily on Canadian crude to produce gasoline and other fuels.

Meanwhile, some northern states import key fuels directly from Canadian refineries. On Friday, Sen. Susan Collins, R-Maine, said on X that 95% of the heating oil used by most Mainers comes from refineries in Canada, while the Air National Guard Base in Bangor “depends completely” on jet fuel and diesel from Canada.

“From fisheries to potato farmers to paper mills, these tariffs will have a significant impact on Maine’s economy and risk increasing costs for our residents,” she added.

The US, Mexican and Canadian auto sectors are also deeply integrated as giants like General Motors and Ford have factories on both sides of the border.

The White House’s announcement on Saturday dashed hopes that it would take a more gradual approach to minimize the immediate impact on consumers. Sources told Bloomberg last month, that some Trump officials considered increasing tariffs by about 2% to 5% a month.

If the tariffs ramp up price pressure, that could force the Federal Reserve to hold off on further rate cuts, and some on Wall Street see the central bank hiking rates later this year.

The three countries that were hit with tariffs Saturday are the largest US trading partners. In 2022, the US imported $536 billion in Chinese goods, $455 billion in Mexican goods, and $437 billion in Canadian products, according to data from the U.S. Trade Representative.

The US imports oil from Mexico as well as a variety of agricultural products, which would likely send some food costs higher. Many imported electronic goods, like Apple iPhones, would also get pricier with tariffs on China.
