In a Federal Register Notice (FRN) published on November 21, 2025, U.S. Customs and Border Protection (CBP) announced it was enhancing its Air Cargo Advance Screening (ACAS) program to require additional data elements.
The new requirements add five new mandatory data elements at the lowest air waybill level, 12 conditional data elements if the shipper is not a verified known consignor, and four data elements that are required under certain conditions.
These requirements went into effect the day of publication, but enforcement is being phased in over a 12-month period. ACAS filers are strongly encouraged to provide optional data elements during this period to expediate clearance.
CBP is also requesting public comments on this interim final rule to the Federal eRulemaking Portal at https://www.regulations.gov by January 20, 2026.
