The president is set to raise taxes on imports arriving from many countries, including Canada and Mexico. That’s on top of the tariffs that the White House has already announced on specific products,

President Donald Trump said on Monday most trading partners that do not negotiate separate trade deals would soon face tariffs of 15% to 20% on their exports to the United States, well above the broad 10% tariff he imposed in April.

Trump has sent letters to leaders of dozens of countries outlining the tariff levels set to begin on Aug. 1. In recent months, Trump has rolled back some of his steepest tariffs, meaning delays could be possible in the case of the Aug. 1 deadline. The Trump administration appears to have stood largely behind the deadline in recent days, however.
