The move will likely have an impact on e-commerce platforms like Shein and Temu along with operators of drop shipping businesses.

The U.S. Postal Service’s decision may block or delay parcels from retailers including Shein and Temu from entering the United States.

The United States Postal Service announced Tuesday night that it is temporarily suspending accepting packages sent from China and Hong Kong until further notice. The suspension is effective immediately, the USPS said. Letters and flats are not included in the suspension, it said.
