X12 104 — Air Shipment Information
Detailed air-shipment manifest: AWB (Air Waybill), pieces, weight, volume, IATA classification, pre-clearance customs data.
Purpose
The 104 lets the air carrier inform the consignee or forwarder of complete shipment detail: AWB number, master/house, dimensions, chargeable weight, IATA dangerous-goods declaration (DGD), pre-clearance customs data for the US (ACE/AES). Often emitted with 309 (Customs Manifest) for customs and 858 (Shipment Information) upstream.
Envelope structure
The 104 travels inside the three X12 envelope levels (ISA/IEA,
GS/GE with functional group AS, and ST/SE).

Common pitfalls
- DG without UN number: IATA rejection — any dangerous class must provide a UN ID (UN1170, etc.).
- Chargeable weight vs gross weight: do not confuse — chargeable is max(gross, volume×166.7) per IATA.
- Origin/destination as IATA vs ICAO code: 104 expects IATA 3-letter (JFK), not ICAO 4-letter (KJFK).
