According to Wired, the e-commerce industry was immediately "thrown into chaos" by the USPS changes. One Canadian trucking company owner, identified only as Daniel, told Wired that many trucks were turned away at the US border yesterday, with his own trucks sometimes only passing through if drivers agreed to dump all packages from China.

The United States Postal Service said Wednesday it is resuming package mail from China and Hong Kong. Those mail shipments were suspended Tuesday night.

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