President Donald Trump on Friday reversed his decision to eliminate the “de minimis” loophole that allowed packages from China valued at under $800 to be processed without customs duties or tariffs, a component of the 10% tariff on Chinese imports that took effect Tuesday—a move that threatened discount Chinese retailers Temu and Shein.

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.
