Here is everything you need to know about the industry’s "must-have" guide for air transport.

A single undeclared dangerous good can bring down an aircraft. That is not hyperbole; it has happened. The IATA DGR exists to prevent that.

The DGR is updated every single year (January 1st). If you are using a version from 2023 in 2025, your shipments are technically non-compliant.

The DGR tells you the standard rules. But specific airlines (Operators) and countries (States) have stricter rules. For example, some passenger airlines ban certain high-powered batteries entirely, even if the DGR says they are allowed. You must check the "Variations" section.
