Cargo-IMP

Cargo-IMP is the legacy IATA EDI standard for exchanging air cargo information between airlines, freight forwarders, ground handlers, and customs authorities. It uses fixed-format text messages with type codes like FWB (Master AWB data), FHL (House AWB list), FFM (flight manifest), FSU (status update).

IATA is migrating the industry to Cargo-XML, a modern XML-based equivalent that supports richer data and aligns with WCO data models. Many air cargo systems still send/receive Cargo-IMP for backwards compatibility while adding Cargo-XML support.
