China hits back with export controls, Canada and Mexico remain under threat. USPS closes then reopens "de minimis" small package loophole

President Donald Trump’s sweeping tariff threats have been touch and go. As it stands currently, the 25 percent tax on goods from Mexico and Canada is on ice for a month, but a 10 percent tariff on Chinese goods is set to take effect on Tuesday, via an executive order of questionable legality.

The Trump administration on Friday delayed the suspension of the so-called de minimis provision, which allows packages worth less than $800 to enter the country duty-free, a move that helps low-cost shopping sites from China that sell everything from fast fashion to furniture.
