Lithium batteries are a regulated dangerous good. A home battery cannot simply be boxed and handed to a carrier — it needs a test summary, a safety data sheet, correct classification and packaging that meets the modal rules for the route it travels. This page sets out what has to be in place, and what RUIDASIMAI provides with every shipment.
Why lithium batteries are shipped as dangerous goods
Lithium cells store energy chemically and can enter thermal runaway if damaged, short-circuited or overheated in transit. Regulators therefore classify them as dangerous goods and require documentation and packaging that reduce those risks. The requirements differ by transport mode, so the same battery may travel under different rules by sea, air and road.
Documents that must accompany a shipment
UN 38.3 test summary
Every lithium cell, module and battery design must pass the UN 38.3 test series, which covers altitude simulation, thermal cycling, vibration, shock, external short circuit, impact and overcharge. The resulting test summary is the document carriers require before they will accept lithium batteries for transport. It must be made available for each battery type shipped.
Material safety data sheet (MSDS / SDS)
The safety data sheet lists the battery’s chemical composition, hazards, and the handling and emergency procedures for transport. It accompanies the UN 38.3 summary.
Dangerous goods declaration
For consignments shipped under full dangerous goods rules, a shipper’s declaration is completed, stating the UN number, proper shipping name, class, packing group and quantity. The carrier uses it to plan handling and to notify the receiving authority.
How the battery is classified
Classification depends on whether the battery travels alone or installed in equipment:
- UN 3480 — lithium-ion batteries shipped on their own. This covers bare battery units travelling as standalone cargo, which is the typical case for a home battery shipped to an installer or distributor.
- UN 3481 — lithium-ion batteries contained in or packed with equipment. This applies where the battery is built into a unit, or shipped in the same package as the equipment it powers.
Lithium iron phosphate batteries fall under the same lithium-ion entries. Their greater thermal stability affects the testing and handling assessment, but it does not exempt them from the requirement to carry the documentation.
Rules by transport mode
Air freight
Air transport is the most tightly regulated mode, governed by the IATA Dangerous Goods Regulations. Lithium-ion batteries shipped alone are subject to a state-of-charge limit, which reduces the energy available to fuel a thermal event if a cell is damaged. Air freight is normally used for samples and urgent small consignments rather than full home battery systems, which are heavy relative to their value and better suited to sea or road.
Sea freight
Sea transport follows the IMDG Code. It is the standard mode for full home battery systems: container capacity, no state-of-charge restriction equivalent to air, and predictable scheduling. Batteries travel in UN-specified packaging within a properly declared container.
Road and rail
Inland movement after discharge from port follows the applicable regional road and rail dangerous goods rules. Where a shipment moves by road within a region, the battery travels under the same documentation set used for the sea leg.
Packaging
Packaging for a home battery must prevent movement, protect the terminals against short circuit, and withstand the handling it will receive. In practice this means:
- The battery is secured inside its carton so it cannot shift or contact other units.
- Terminals are protected against accidental short circuit during handling.
- The outer packaging meets the specification required for the classification and mode.
- Marking and labelling identify the consignment as lithium batteries, so handlers and emergency services can act correctly.
- Cartons are palletised and unitised for container loading to limit movement in transit.
Each unit is packed for its specific model — the stackable, wall-mounted and floor-mounted enclosures have different weights and centres of gravity, so the packing design is not interchangeable between them.
What RUIDASIMAI provides
- UN 38.3 test summaries for the battery types shipped
- Material safety data sheets
- Dangerous goods documentation prepared for the chosen mode and route
- Export packing designed for the specific model, unitised for container loading
- Certification documentation covering UN 38.3, MSDS, IEC 62619, CE, UL 1973 and UL 9540 depending on model — see home battery certifications
Commercial terms
Delivery terms — Incoterms, port of departure, transit time and freight arrangement — depend on destination, consignment size and the route chosen for that shipment, and are agreed per order. Because each destination carries its own import requirements, these are confirmed in writing before dispatch rather than quoted generically.
For a specific destination and quantity, send your requirements through the contact form and the terms for that lane will be confirmed. For documentation questions on a battery model you are already specifying, see certifications or the frequently asked questions.
