Shippers & Packers
If you package or prepare dangerous goods for air transport in any way, you must have access to the most up-to-date manual.

Air Operators
If you accept dangerous goods for carriage by air, your staff must have the current IATA DGR available as a reference at all times.
The IATA DGR is the global industry standard for DG by air — covering international requirements plus State & Operator variations. It’s a mandatory resource for safe, compliant DG handling.
