The U.S. Postal Service has temporarily suspended the acceptance of incoming international parcels from China and Hong Kong

The U.S. Postal Service has temporarily suspended the acceptance of incoming international parcels from China and Hong Kong, threatening the e-commerce giants Shein and Temu. It said the flow of letters will not be affected.

The announcement comes just days after U.S. President Donald Trump signed an executive order that terminated the “de minimis” exemption, a long-standing rule that allowed anyone, including exporters, to ship packages worth less than $800 to the U.S. without duties or needing to undergo inspections.

It also follows the introduction of a 10% tariff on Chinese imports to the U.S.
