ICAO has issued an addendum to the 57th edition DGR for hazardous materials shipped by air that became effective January 1, 2016. The addendum includes significant changes to various areas of the DGR, including the packaging and transportation of lithium batteries.
Packages that contain two or more pieces of equipment that contain lithium batteries must be labeled. The addendum also includes Appendix H which shows some additional changes being made. They include changes to some UN numbers, proper shipping names, several changes to packaging instructions, revisions to some existing entries, and some new entries.
