Why the Annual DGR Edition Matters
The IATA Dangerous Goods Regulations are reissued every January. Each edition carries changes ranging from minor clarifications to substantive new requirements. The aviation industry is required to adopt the new edition on the effective date, but shippers have a three-month transition window during which the previous edition can still be used. After that window, shipments using the prior edition’s rules are rejected at acceptance.
If you ship hazmat by air through Miami or any other U.S. gateway, here is what the latest edition changes and what you need to adjust in your SOPs.
Lithium Battery State of Charge
The most operationally consequential change is the formalization of state of charge requirements for stand-alone lithium ion battery shipments by cargo aircraft only under UN3480. The 30 percent state of charge cap that has been industry practice for several editions is now codified in Special Provision A331 with clearer documentation requirements.
The change in practice: shippers must now retain written documentation that each shipment was verified at 30 percent SOC or below, signed by a trained shipper, and produce that documentation upon CBP or operator request. The verification can be by direct measurement, by manufacturer attestation for sealed cells, or by a documented controlled-discharge procedure. The documentation has to be retained for at least three months after the shipment date.
For shippers running consistent SKUs at consistent SOC, the answer is a written SOP that references the manufacturer’s depleted-state datasheet and ties each lot to a discharge record. For shippers running mixed lots, the answer is direct measurement and a per-shipment log entry.
PI 376 Damaged, Defective, and Recalled Lithium Batteries
Packing Instruction 376, which covers damaged, defective, and recalled lithium batteries, has been tightened. The performance test for the outer packaging now requires a specific thermal exposure profile in addition to the existing 1.2 meter drop test and stack test. The thermal profile requires the packaging to maintain integrity at 75 degrees Celsius for 12 hours, simulating cargo hold or staging area conditions during a thermal event in a neighboring package.
Existing UN-spec 4G fiberboard boxes used for PI 376 do not automatically meet the new thermal requirement. Shippers using these boxes need to either obtain manufacturer thermal certification documentation or switch to packaging that has been tested to the new profile. The major UN-spec packaging vendors have already begun issuing updated test reports, but you have to ask for them.
Overpack Labeling Clarification
A long-standing ambiguity in overpack labeling for lithium batteries has been resolved against shipper convenience. The previous text was read by some shippers to mean the lithium battery mark only needed to be on the outer overpack if the inner packages were already marked and visible. The current edition makes explicit that both layers need to be marked when the inner package marks are not visible through the overpack.
The practical result: shippers using shrink-wrap or opaque overpacks need to mark the overpack as well as the inner packages. Shippers using transparent overpacks where the inner marks are clearly visible can continue marking the inner only.
State and Operator Variation Updates
Every annual edition refreshes the state and operator variations table. Notable changes for 2026 include tightened U.S. variations on damaged, defective lithium battery transport, updated Canada CAG entries for lithium ion equipment over 100 Wh, and expanded operator-specific entries for the major integrators.
Worth checking annually: the OPS list for any operator you tender to and the state list for any origin or transit state on your shipments. The state list in particular changes more than shippers expect, and a variation that did not affect you last year may apply this year.
Documentation Form Changes
The Shipper’s Declaration for Dangerous Goods form has been refined. The current edition’s form includes additional fields for digital DGD adoption and clarifies the package count and net quantity fields. Shippers using paper DGDs should switch to the updated form within the transition window. Shippers using software-generated DGDs through systems like DGOffice or InfiniteTrack will receive the updated template through their vendor.
The other documentation change worth noting is the lithium battery test summary requirement under UN 38.3. The summary documentation must be available upon request and must be in a form that allows verification of cell- and battery-level testing for the specific product being shipped. Generic supplier statements that do not tie to a specific lot or SKU are not sufficient.
What to Update Now
For most shippers, the operational checklist is short. Update lithium battery state of charge SOPs to include written verification per shipment. Verify packaging vendor thermal test certifications for PI 376. Update overpack labeling SOP if you use opaque overpacks. Refresh the state and operator variation reference in your DGD software. Train staff on the updated DGD form.
A hazmat operation that does these five things in the transition window will be fully compliant when the prior edition is no longer accepted. A hazmat operation that does not will run into acceptance rejections and PHMSA citations within 90 days.
