Order includes mechanism to raise rates if the impacted countries retaliate against U.S. Trump’s order also includes a mechanism to escalate the rates if the countries retaliate against the U.S., as they are possibly prepared to do. The decision throws the global economy and Trump's own political mandate to combat inflation into possible turmoil, though the Republican president posted on social media that it was necessary “to protect Americans.”.

Trump declared an economic emergency in order to place duties of 10 percent on all imports from China and 25 percent on imports from Mexico and Canada. But energy imported from Canada, including oil, natural gas and electricity, would be taxed at a 10 percent rate. For the moment, Mexico plans to stay cool-headed as it weighs its options. Mexico President Claudia Sheinbaum, appearing Saturday at an event promoting a government housing program outside Mexico City said, “I’m calm, I’ve been saying since yesterday, because I know that Mexico’s economy is very powerful, very strong.”.

The order signed by Trump contained no mechanism for granting exceptions, the official said, a possible blow to homebuilders who rely on Canadian lumber as well as farmers, automakers and other industries. The Trump administration put the tariffs in place to force the three countries to stop the spread and manufacturing of fentanyl, in addition to pressuring Canada and Mexico to limit any illegal immigration into the United States.

The official did not provide specific benchmarks that could be met to lift the new tariffs, saying only that the best measure would be fewer Americans dying from fentanyl addition. The order would also allow for tariffs on Canadian imports of less than $800. Imports below that sum are currently able to cross into the United States without customs and duties. “It doesn’t make much economic sense,’’ said William Reinsch, senior adviser at the Center for Strategic and International Studies and a former U.S. trade official. “Historically, most of our tariffs on raw materials have been low because we want to get cheaper materials so our manufacturers will be competitive ... Now, what’s he talking about? He’s talking about tariffs on raw materials. I don’t get the economics of it.’’.

The Republican president is making a major political bet that his actions will not significantly worsen inflation, cause financial aftershocks that could destabilize the worldwide economy or provoke a voter backlash. AP VoteCast, an extensive survey of the electorate in last year's election, found that the U.S. was split on support for tariffs. With the tariffs, Trump is honoring promises that are at the core of his economic and national security philosophy. But the announcement showed his seriousness around the issue as some Trump allies had played down the threat of higher import taxes as mere negotiating tactics.

The president is preparing more import taxes in a sign that tariffs will be an ongoing part of his second term. On Friday, he mentioned imported computer chips, steel, oil and natural gas, as well as against copper, pharmaceutical drugs and imports from the European Union — moves that could essentially pit the U.S. against much of the global economy. It is unclear how the tariffs could affect the business investments that Trump said would happen because of his plans to cut corporate tax rates and remove regulations. Tariffs tend to raise prices for consumers and businesses by making it more expensive to bring in foreign goods.
