Manifest
Also known as: Cargo Manifest
A manifest is the comprehensive list a carrier files describing all the cargo aboard a conveyance — each shipment's shipper, consignee, description, quantity, and weight — submitted to the customs authority before or upon arrival. It is the master inventory against which customs assesses risk, reconciles entries, and controls what physically comes off a vessel, aircraft, or truck. Advance manifest rules require much of this data to be transmitted before the cargo is even loaded at origin, giving authorities time to screen shipments for security and compliance long before they reach the border.
The carrier's declaration of what is aboard, and the record your entry is matched against. When they disagree the entry rejects. Mail is the awkward case: postal shipments do carry advance electronic data — ITMATT and PREDES under the UPU message set — but there is no ACE bill of lading for the entry to match to, so the filing goes against an assigned facility control number instead.
Where it matters for compliance
- Advance manifest data is the carrier's obligation, but a mismatch is the importer's delay.
- Non-manifested shipments are filed without a manifest match, using the assigned control number.
