Large lithium batteries are no longer a niche shipment. The International Energy Agency’s Global EV Outlook 2024 reports that electric-vehicle battery demand exceeded 750 GWh in 2023, rising about 40% from the previous year. Behind that growth are real cargoes: heavy battery packs, industrial storage units, and equipment that may need careful handling at every transfer point.
Shipping large lithium batteries from China takes more than booking space on a vessel or aircraft. Battery specifications, shipment configuration, packaging, documents, and the chosen transport route can all affect what a carrier will accept. Requirements also depend on the battery type and current transport rules, so exporters should verify details with qualified logistics providers before dispatch. Small oversights matter. A missing test summary or unclear battery label can trigger delays, extra handling, or a rejected booking.
This guide explains the practical decisions behind shipping large lithium batteries, from gathering product information to coordinating pickup and delivery. It draws on established industry guidance and emphasizes checking current carrier and regulatory requirements rather than relying on old templates. Even a careful checklist has limits. I’ve seen how easy it is to treat every battery shipment as routine, when a slight change in configuration can alter the plan. That is a useful reminder: confirm the shipment details before the cargo leaves the warehouse.
Before booking a large battery shipment from China, identify its chemistry and configuration. UN 3480 covers lithium-ion batteries shipped alone. UN 3481 applies when they are packed with equipment or installed inside it. These codes are not interchangeable. The IATA Dangerous Goods Regulations, 66th edition, set 100 Wh as a key threshold for lithium-ion batteries. Calculate watt-hours by multiplying nominal volts by amp-hours. A label reading 25.6 V and 5 Ah equals 128 Wh. Check the label. If the rating is missing or unclear, request the manufacturer’s test summary and confirm the figures before preparing shipping documents.
Lithium-metal batteries use different UN numbers: UN 3090 when shipped alone, and UN 3091 when packed with or contained in equipment. Under the same IATA rules, the relevant battery-level limit is 2 g of lithium content; the cell-level limit is 1 g. Do not confuse lithium content with battery weight. Batteries above the applicable limits generally require stricter dangerous-goods handling, packaging, marks, and documentation. The UN Manual of Tests and Criteria, subsection 38.3, also establishes testing requirements for lithium battery types offered for transport. A common paperwork weakness is copying a product’s gross weight instead of recording its chemistry, Wh rating, and lithium content. That detail is easy to overlook, and it can delay a shipment. Recheck the classification against the current carrier and route requirements.
