President Donald Trump's new tariff orders against Canada, Mexico and China all contain clauses suspending a duty-free exemption for low-value shipments below $800 that is widely seen as a loophole that has allowed shipments of fentanyl and its precursor chemicals into the United States.

President Trump has threatened to impose tariffs on Canada over drug trafficking, equating it with Mexico. U.S. government reports do not support the claim.

The Trump administration is following through on its promise to impose 25% tariffs on goods imported from Mexico and Canada and raise tariffs on Chinese goods on Saturday.
