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.

The US Postal Service is temporarily suspending inbound international packages from China and Hong Kong Posts, potentially delaying or blocking shipments from retailers like Shein and PDD Holdings Inc.

Only parcels arriving in the US from China and Hong Kong are affected for now, as the restriction doesn't apply to letters and flat mail.
