President Trump’s new executive order suspends the de minimis exemption for global low-value imports, a move that could raise prices for online shoppers and restrict package shipments from retailers like Shein and Temu.

Any goods shipped through the international postal network will be subject to tariff rates based on the value of the package and its country of origin.

The low-cost shipments were previously excluded from tariffs; President Trump said the loophole has allowed countries to avoid taxes and smuggle drugs into the U.S.
