IATA DGR
Definition
The IATA Dangerous Goods Regulations airlines follow for carrying dangerous goods by air, based on the ICAO Technical Instructions.
The IATA Dangerous Goods Regulations are published every year and add airline and country variations to the ICAO Technical Instructions. Many chemicals are allowed by air only in limited quantities per package, some only on cargo aircraft and some are forbidden.
Air shipments of dangerous goods need a shipper's declaration, correct packaging and labels, and trained staff. Samples of hazardous chemicals sent by courier follow the same rules.
