What is the IATA DGR?

The International Air Transport Association’s Dangerous Goods Regulations (IATA DGR) is the manual used by dangerous goods/hazardous materials shippers, freight forwarders, brokers, and air carriers around the world to mitigate the risks posed by hazardous materials in air transportation.  

The IATA DGR combines international hazmat regulations from the United Nations, the ICAO Technical Instructions or "TI," with unique requirements and preferences of member airlines—including passenger airlines and major cargo carriers like UPS and FedEx.

The IATA DGR is updated annually and all revised requirements take effect on January 1 of each new year.

One Upcoming Change for Lithium Battery Air Shippers

In last year's Significant Changes document, one update to Packing Instructions 965 and 966 included a provision about recommendary additions become mandatory in 2026.

PI 965 and PI 966—Both packing instructions have several notes added to reiterate that batteries shipped at a reduced SoC are less prone to thermal runaway. The 30% SoC restriction on lithium batteries in PI 965, will be extended into PI 966, initially as a recommendation in 2025, and becoming mandatory in 2026 for batteries with a Wh rating > 2.7 Wh. Provision has been made for State Approvals where the shipper wishes to offer these batteries for transport at an SoC>30%. There will not be a provision to ship cells or batteries at an SoC>30% under Section II of PI 966. These will have to be offered in accordance with Section I.
