The Air Cargo Manifest form, recognized officially by the Department of Homeland Security and overseen by U.S. Customs and Border Protection, plays a pivotal role in facilitating international air shipments into the United States. Holding an OMB Control Number 1651-0001 and subject to the regulations outlined in 19 CFR 122.35, 122.48, 122.52, 122.54, 122.73, 122.113, 122.118, this form serves multiple purposes, from detailing the cargo's nature to documenting both shipper and consignee information. Its structured format, which breaks down specifics such as flight number, ports of lading and unlading, and marks of nationality and registration, ensures that each air cargo shipment is accompanied by a standardized declaration. Notably, the form is flexible in its requirement for detail level, allowing for the attachment of air waybills as a substitute for completing certain sections. This procedural nuance underscores the form's designed efficiency in both manual and automated preparation systems, catering to the diverse operational modes of freight forwarders and carriers alike. The prerequisites for its use, including the possession of a valid OMB control number and adherence to the Paperwork Reduction Act, underline the legal and operational significance of the Air Cargo Manifest form in the broader context of international trade and national security.
