President-elect Donald Trump’s threatened tariffs might be more of a political negotiating tactic than a set-in-stone policy, but the outcome is sure to have huge impacts on American consumers.

Mexico and Canada are the United States’ top two trading partners, accounting for nearly 30% of trade volumes.

The president-elect said that he would impose the across-the-board tariffs on Day 1 and that they would stay in place until Canada, Mexico and China halted the flow of drugs and migrants.
