Sea freight — FCL & LCL
IMDG-aligned ocean moves for lithium battery cargo when volume and transit time favour sea over air.
FCL or LCL?
Container choice affects more than price.
Volume, cargo control, consolidation acceptance and destination handling all influence the workable sea option.
Container choice
Dedicated container or consolidated cargo
- FCL · one shipper's cargo in the container
- More control over loading and segregation
- Useful when volume or cargo profile supports a dedicated unit
- Container declaration, placarding and stowage still require review
- Pickup, stuffing and port cut-offs must be coordinated
- LCL · shared with other shippers' cargo
- Practical for smaller lots when a consolidator accepts the cargo
- DG compatibility and consolidation restrictions can narrow options
- Package marks and documentation must stand on their own
- Additional handling increases the value of robust outer packaging



IMDG in plain English
Sea shipments of lithium batteries are treated as dangerous goods under the IMDG Code. That means correct classification, packing, marks and labels, and documentation for the booking and the vessel operator.
When sea is often preferred
- Larger volumes where air cost or restrictions are impractical
- Cargo that is eligible for sea but faces tight air state-of-charge or cargo-aircraft-only limits
- Routes where the schedule meets your delivery window

Cargo screening
What we need to know about the battery
Battery type or UN entry if known, packing method, weight and volume, origin and destination, UN 38.3 test summary and SDS, and the cargo-ready date.
Cargo screening
How is the battery presented, and in what condition?
- Cells or batteries alonePacks, cells or spares shipped without equipment.UN 3480 (lithium-ion) · UN 3090 (lithium metal)Cargo guide
- Packed with equipmentBattery and the device it powers in the same outer package, not installed.UN 3481 · UN 3091 (packed with equipment)Cargo guide
- Contained in equipmentBattery installed in the device, e.g. tools, instruments, e-mobility parts.UN 3481 · UN 3091 (contained in equipment)Cargo guide
Condition screening
- New, testedStandard review of test summary, SDS and packing.
- Returned or usedScreened for damage, defects and missing test data before anything is offered.
- Damaged, defective or recalledSeparate special provisions; many carriers decline. Reviewed case by case.
