President Donald Trump is poised to unleash his first wave of tariffs Saturday, sending foreign governments and businesses rushing to skirt potential duties and prepare for retaliation.

President Donald Trump confirmed Thursday that he’s planning to levy a 25% tariff on imports from Mexico and Canada starting Saturday—with broader import taxes potentially soon following—reflecting his campaign promises to implement high tariffs, against the views of many economists who believe Trump’s plan would burden everyday consumers.

The 25% tax that President Donald Trump plans to slap as soon as Saturday on imports from Canada and Mexico could drive up the price of everything from gasoline to pickup trucks to the guacamole dip that features so prominently at American Super Bowl parties.
