Lithium Battery Transport in 2026: 7 New Rules You Can't Afford to Miss

The lithium battery supply chain is moving quickly, but compliance expectations are moving just as fast.

On January 1, 2026, new air transport requirements took effect under the 67th Edition of the IATA Dangerous Goods Regulations. The most discussed change is the mandatory 30% state-of-charge requirement for additional categories of lithium-ion battery shipments.

For manufacturers, government agencies, armed services, insurers, tow yards, and logistics teams, this is more than a paperwork update. A shipment rejected at the dock can delay a vehicle recovery, interrupt a manufacturing schedule, complicate an insurance claim, or leave a damaged battery sitting in an unsafe location.

E.A.L.M., LLC approaches lithium battery logistics as a full-lifecycle responsibility. Safe transportation is connected to classification, packaging, storage, decommissioning, recycling, and documented chain of custody.

Here are seven rules and compliance priorities every organization should understand in 2026.

1. Standalone lithium-ion batteries must remain at or below 30% state of charge

Standalone lithium-ion batteries shipped as UN 3480 under Packing Instruction 965 must be offered for air transport at a state of charge, or SoC, not exceeding 30% of rated capacity.

This requirement applies when batteries are shipped by themselves rather than installed in equipment or packaged with the equipment they power. Standalone batteries are also generally forbidden as cargo on passenger aircraft and must move under the applicable cargo aircraft requirements.

The purpose is straightforward. A battery with less stored energy presents a lower potential for thermal runaway during transport.

For a shipper, however, the practical challenge is proving that the battery was prepared correctly. A reliable process should identify:

• The battery chemistry and UN classification
• The rated capacity and watt-hour rating
• The measured state of charge
• The applicable packing instruction
• The required marks, labels, and documents
• The personnel responsible for final verification

A verbal assurance from a warehouse or production team is not a substitute for a repeatable process.

2. Batteries packed with equipment now face expanded SoC requirements

The 2026 regulations make the 30% SoC limit mandatory for more lithium-ion batteries packed with equipment under PI 966.

For Section I shipments, lithium-ion cells and batteries must generally be offered at no more than 30% SoC. For Section II shipments, the requirement applies when a cell or battery exceeds 2.7 watt-hours.

This affects many commercial shipments, including spare batteries packed with power tools, electronics, medical devices, industrial equipment, and other products.

The distinction between “contained in equipment” and “packed with equipment” matters. A battery installed inside the device it powers may fall under PI 967. A spare battery placed in the same package as the device is generally treated differently under PI 966.

That difference can change the documentation, packaging, marking, and handling requirements. Manufacturers and distributors should not rely on a general statement such as “the battery is with the product.” The exact configuration must be reviewed.

3. Battery-powered vehicles over 100 Wh must meet a reduced-charge requirement

Electric vehicles, mobility devices, industrial vehicles, and other battery-powered vehicles are receiving increased regulatory attention.

Under PI 952, vehicles powered by lithium-ion batteries with a watt-hour rating exceeding 100 Wh must be offered for air transport with either:

• A state of charge not exceeding 30% of rated capacity, or
• An indicated battery capacity not exceeding 25%

This applies to vehicles classified under entries such as UN 3556, Vehicle, lithium-ion battery powered.

The 25% indicated capacity option recognizes that some vehicles display remaining battery capacity rather than a conventional SoC reading. It is a practical method, but it still requires a documented pre-shipment check.

This requirement is especially important for EV manufacturers, fleet operators, tow yards, insurers, and government agencies. A vehicle involved in a collision may not be in a condition where its battery can be treated like an ordinary shipment. Its condition, accessibility, damage status, and transport mode must be evaluated before movement begins.

4. Shipments above 30% SoC require approvals that should not be treated as routine

A lithium-ion battery shipment above the applicable 30% SoC limit may be possible under Special Provision A331, but only with written approval from the State of Origin and the State of the Operator under conditions established by those authorities.

This is not a convenient alternative for routine logistics.

Approvals take time, and an airline or operator is not required to accept a shipment simply because a shipper has obtained one approval. The IATA 2026 Battery Guidance Document advises shippers to coordinate with an operator before seeking approval.

The better operational strategy is to build SoC reduction into the shipping process before the battery reaches the loading area. When that is not possible, the shipper should identify the regulatory path early and coordinate with a qualified dangerous goods specialist.

Last-minute decisions create pressure. Pressure creates mistakes.

5. Batteries contained in equipment still require careful review

For lithium-ion batteries contained in equipment under PI 967, the 2026 IATA requirements continue to recommend, rather than universally mandate, a reduced state of charge.

The recommendation is to offer the equipment with the battery at no more than 30% SoC or with an indicated battery capacity not exceeding 25%.

That distinction is important, but it should not be interpreted as permission to ignore charge levels. Operators, states, customers, and contract requirements may impose stricter conditions. A cautious shipper should also consider the consequences of an incident, inspection, rejected load, or insurance review.

The safest approach is to treat the reduced-charge recommendation as a normal preparation standard wherever operationally feasible.

6. UN 38.3 test summaries must be available

Lithium-ion cells and batteries must meet the applicable testing requirements in Part III, subsection 38.3 of the UN Manual of Tests and Criteria.

Manufacturers and subsequent distributors must make a lithium battery test summary available. The document should identify information such as:

• The manufacturer
• The testing laboratory
• The test report identification number
• The date of the report
• The battery description
• The watt-hour rating or lithium content
• The models covered
• The tests performed and results

A test summary does not necessarily have to accompany every shipment. However, manufacturers, distributors, shippers, transport providers, regulators, and customers must be able to access it when needed.

For battery manufacturers and EV companies, this is a document-control issue as much as a transportation issue. Battery models change. Suppliers change. Repairs, refurbishments, and design modifications can affect whether a test summary still applies.

A controlled, searchable record system can prevent a small documentation gap from becoming a shipment-wide problem.

7. Packaging, marking, training, and handoff procedures remain decisive

A compliant battery can still become a noncompliant shipment if it is packaged, marked, or documented incorrectly.

Battery terminals must be protected from contact with other batteries, metal objects, or conductive surfaces. Batteries must be cushioned and secured to prevent movement. The correct marks and labels must be visible, and overpacks must be handled according to the applicable requirements.

Some shipments require a Shipper’s Declaration for Dangerous Goods. Others require specific statements on the air waybill. Section IB shipments remain subject to dangerous goods training requirements, while personnel preparing Section II shipments must receive adequate instruction.

Compliance should continue after transportation

Lithium battery logistics does not end when a shipment reaches its destination.

Some batteries will be returned, damaged, recalled, retired, or removed from larger systems. Others will come from electric vehicles, energy storage systems, military equipment, or emergency response operations. Those assets may require isolation, evaluation, decommissioning, recycling, or disposal.

That is where a full-lifecycle partner becomes valuable.

E.A.L.M., LLC supports organizations that need more than a carrier. Its focus includes compliant lithium ion battery transportation, battery recycling, BESS decommissioning, and facilities management. For a tow yard, that may mean helping manage a damaged EV after recovery. For an insurer, it may mean supporting a documented chain of custody. For a manufacturer, it may mean coordinating the movement and final disposition of batteries across multiple locations.

The practical takeaway for 2026

The 30% SoC requirement is the headline, but effective compliance depends on the entire workflow.

Organizations should ask:

1. Can the battery be correctly classified before transport?
2. Is the state of charge measured and documented?
3. Does the shipment involve equipment, a vehicle, or a standalone battery?
4. Is a current UN 38.3 test summary available?
5. Are packaging, marking, labeling, and documentation requirements clear?
6. Have employees and contractors received appropriate instruction?
7. Is there a plan for damaged, recalled, retired, or end-of-life batteries?

The organizations that answer these questions early will be better prepared for inspections, delays, claims, and changing regulations.

E.A.L.M. believes safer lithium battery transportation begins with practical planning and continues through the asset’s full lifecycle. Readers working through a difficult battery shipment, decommissioning project, or recycling decision are invited to share the compliance challenge their organization is facing. It may help another team avoid the same roadblock.
