| Battery classification |
LiFePO4 batteries are lithium-ion batteries for transport purposes. Standalone batteries are generally identified as UN 3480; batteries packed with equipment or contained in equipment are generally UN 3481. |
Identify whether the shipment is standalone, packed with equipment, or installed in equipment before selecting the applicable transport instructions. |
| UN 38.3 testing |
Lithium batteries offered for transport generally must meet the applicable UN Manual of Tests and Criteria, subsection 38.3 requirements. |
Obtain the battery’s UN 38.3 test summary from the manufacturer or supplier and make it available as required. Do not offer an untested battery for transport unless an applicable exception or approval permits it. |
| Packaging selection |
Packaging requirements depend on the battery configuration, capacity, transport mode, applicable regulations, and any available exception. |
Use packaging permitted by the applicable packing instruction. Choose packaging that is suitable for the battery’s weight and can withstand normal transport handling; do not assume one box specification fits every shipment. |
| Terminal protection |
Exposed terminals can create a short-circuit risk if they contact metal or another conductive surface. |
Insulate or otherwise protect terminals, separate batteries to prevent contact, and secure the contents so they cannot shift or be damaged in transit. |
| Outer packaging and contents |
The package must prevent movement and protect the batteries against damage under the applicable packing requirements. |
Use suitable cushioning and a strong outer package where required. Keep batteries away from loose conductive items, and make sure internal packaging does not cause pressure or damage to the battery. |
| Air transport |
Air shipments have specific requirements under the applicable ICAO Technical Instructions and IATA Dangerous Goods Regulations. Standalone lithium-ion batteries are subject to additional restrictions, including limits on passenger-aircraft carriage. |
Confirm the current packing instruction, state-of-charge limits, labels, documents, and carrier acceptance rules before booking. Requirements differ by battery configuration and may change. |
| Sea and other transport modes |
Sea, road, and rail shipments are subject to their respective dangerous-goods regulations and local implementation requirements. |
Check the current rules for the full route, including transit countries, ports, and the carrier. Confirm that the selected package, marks, labels, and shipping documents match the shipment classification. |
| Marks, labels, and documents |
Required marks, labels, and documentation depend on the applicable regulations, package configuration, shipment size, and any permitted exception. |
Use only the marks and labels required for the shipment. Ensure the shipping description and accompanying documents are accurate, complete, and consistent with the package. |
| Damaged or defective batteries |
Batteries that are damaged, defective, recalled, or suspected of overheating may face strict transport restrictions; air transport is particularly restrictive. |
Do not pack or ship such batteries as routine cargo. Seek guidance from a qualified dangerous-goods professional and the carrier before arranging any movement. |
| Final compliance check |
International requirements vary by mode, route, battery details, and the regulations in force on the shipping date. |
Before dispatch, verify the current rules with the relevant regulator or a qualified dangerous-goods specialist, and obtain acceptance from the chosen carrier. |
