President Donald Trump said his proposed tariffs on Mexico and Canada will go into effect March 4, and that China will be charged an additional 10% tariff.

Summary

Trump announced 25% tariffs on Mexico and Canada will begin March 4, claiming continued drug trafficking concerns despite earlier border enforcement pledges.

On the same date, China will face an additional 10% tariff, bringing total Chinese import tariffs to 20%.

This announcement contradicted earlier statements by White House Economic Director Kevin Hassett, who suggested all tariff decisions would come after an April 1 study.

Trump’s broader tariff agenda includes global 25% steel and aluminum tariffs starting March 12 and reciprocal tariffs on nations with duties on US imports.
