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.

The Trump administration said Saturday it had imposed a 25% tariff on goods from Canada and Mexico and a 10% tariff on China.
