The 66th Edition of the IATA Dangerous Goods Regulations (DGR), effective 1 January 2025, introduces critical updates that businesses transporting dangerous goods by air need to understand. These changes are designed to enhance safety, simplify compliance, and reflect evolving technologies and regulations. 

While many discussions around these updates focus solely on the technical details, this blog takes a practical approach, outlining not just what’s changing but why it matters to you. 

What’s New in the 66th Edition? 

1.Updates to Lithium and Sodium-Ion Batteries 

Packing Instructions: Stricter state-of-charge limits for lithium and sodium-ion batteries reduce risks of incidents during transport. For example, lithium ion batteries packed with equipment (PI 966) with a watt-hour rating in excess of 2.7Wh must be offer for transport at a state of charge not exceeding 30% of their rated capacity from 1 January 2026. 

New UN Numbers: Vehicles powered by lithium or sodium-ion batteries are now distinctly classified, improving safety protocols for these technologies. 

2.Simplified Marking and Labelling 

The new “Battery Mark” and combined hazard label for lithium and sodium-ion batteries make it easier to comply with labelling requirements while reducing errors. 

3.Streamlined Transport of Vaccines 

Broader exemptions now cover pharmaceutical products containing genetically modified organisms (GMOs), simplifying the transport of vaccines and related products. 

4.Clearer Accessibility for Test Summaries 

Shippers can now “make available” UN Test Summaries in a digital format, eliminating unnecessary paperwork while maintaining safety compliance. 

5.Improved Packing and Documentation 

Changes to packing instructions and documentation, such as when calculating the “Q” value, the maximum net quantities from the relevant packing instructions are to be consistent with the intended aircraft type, make it easier to manage complex shipments. 

Why These Changes Are Important 

1.Avoiding Costly Mistakes 
Incorrect documentation or packaging can lead to shipment rejections, delays, or fines. These updates provide clear instructions to reduce the risk of non-compliance. 

2.Making Your Job Easier 
Simplified labelling and packing rules mean less time spent on figuring out what goes where, making day-to-day operations smoother for shippers and warehouse teams. 

3.Keeping Everyone Safe 
Items like batteries are everywhere—from mobile phones to electric vehicles—but they carry significant fire risks. These changes are designed to keep your shipments safe, protecting both people and property. 

4.Supporting Innovation 
By addressing emerging technologies like sodium-ion batteries and easing vaccine transport, the regulations help businesses keep pace with innovation while staying compliant. 

5.Planning for the Future 
The updates are designed to help your business adapt to future changes, giving you confidence that your operations are ready for what’s next.
