IATA Lithium Battery Shipping in 2026: What Just Changed for South Florida Shippers

If you ship lithium batteries by air, the IATA Dangerous Goods Regulations (DGR) are not a document you read once and forget. The 67th Edition for 2026 brought another round of updates on lithium battery classification, packaging, and state and operator variations. South Florida shippers moving cargo through Miami International, Fort Lauderdale-Hollywood, and Palm Beach International need to be current, because a rejected shipment at MIA is not just a delay. It is a re-pack, a re-declaration, and often a missed flight.

The classification refresher you cannot skip

Lithium batteries fall under four primary UN numbers that every shipper should know cold. UN3480 covers lithium-ion batteries shipped on their own. UN3481 covers lithium-ion batteries packed with or contained in equipment. UN3090 covers lithium metal batteries on their own. UN3091 covers lithium metal batteries packed with or contained in equipment. Section II, IA, and IB designations sit underneath these, and they determine your packaging requirements, your labeling, and whether the package can move as cargo aircraft only.

Key 2026 changes worth flagging

Three changes have been catching shippers off guard this year. State of charge limits for standalone lithium-ion shipments continue to be 30 percent of rated capacity. Several operators, including major carriers serving MIA, now require pre-approval before tendering Section IA or IB shipments. And the requirement for a Lithium Battery Test Summary (per UN 38.3) has been more strictly enforced. If you cannot produce a manufacturer’s test summary on demand, expect the shipment to be held.

State and operator variations are the trap

The DGR includes state variations (rules added by a country) and operator variations (rules added by an airline) that can override the base regulation. Carriers operating into Latin America and the Caribbean out of Miami have a long list of these. An operator variation might prohibit Section II lithium metal cells altogether, or require segregation that the standard DGR does not. Ignoring an operator variation is the single most common cause of a same-day rejection at MIA cargo terminals.

Repacking and segregation realities

When a shipment arrives at the airport and fails inspection, repacking is not optional. It has to be done by a certified hazmat professional, with compliant inner packaging, cushioning, outer packaging that meets the relevant Packing Instruction (PI 965, 966, 967 for lithium ion; PI 968, 969, 970 for lithium metal), proper marks and labels, and a fresh Shipper’s Declaration. Doing that under time pressure at the airport is expensive. Doing it correctly the first time at your facility is not.

Why a mobile hazmat compliance partner matters

Most South Florida shippers do not have a full-time IFA-certified DGR specialist on staff. They do not need one. What they need is a mobile compliance partner who can come to the warehouse, classify the cargo, pack it correctly, prepare the Shipper’s Declaration, and stay with the freight through the carrier handover. Go Hazmat does exactly that across Miami-Dade and Broward, including pre-shipment audits for high-volume shippers who want to catch issues before the truck rolls.

Three things to do before your next lithium battery shipment

First, confirm your UN 38.3 test summary is on file for every battery model you ship. Second, check the most recent operator variations published by the airline you intend to use; they update more often than the DGR itself. Third, if you ship enough volume to matter, run an annual audit with a certified hazmat partner. The cost of one rejected MIA shipment will pay for the audit several times over.
