Canada and Mexico are the top buyers of U.S. exports in more than 72% of all export categories, according to my analysis of the latest U.S. Census Bureau data.

Canada planned to impose tariffs on the U.S. in response to Trump. Here’s how they would impact Washington state’s economy.

Some of the purported concessions that led to a 30-day pause on the tariffs were things Canada and Mexico had already done before Trump’s threat, but it’s complicated.

Trump has also threatened to introduce tariffs - a tax on imports - on goods from Canada and Mexico, but paused these for 30 days after both countries agreed to boost border security. The US president has said tariffs are needed to help the American economy and to "protect" the country from the "major threat of illegal aliens and deadly drugs".

Donald Trump is the first president to use the International Emergency Economic Powers Act to impose tariffs, teeing up likely legal battles that will test his executive authority.

Tariffs could affect a variety of companies. Though the tariffs are on uncertain terrain legally, courts have been reluctant to second-guess the president's powers to implement trade policy.
