Effective March 18, 2023, Customs & Border Protection (CBP) will enact the Uyghur Forced Labor Prevention Act (UFLPA) Region Alert enhancement to the Automated Commercial Environment (ACE). This enhancement will provide early notification to importers of goods that may be produced prohibited from entry in the United States due to having been produced in the Xinjiang Uyghur Autonomous Region (Xinjiang or XUAR) .
Specific changes for trade users include three new validations to ACE:
Postal code will be a required field
An error message will be received if the postal code is not a valid Chinese postal code
A warning message will be received when a XUAR region postal code is provided
