How to Ship Lithium Batteries from China by Air

Air is the fastest way to move lithium batteries out of China — but it is also the most regulated. This guide walks through the five things that decide whether your battery cargo flies: classification, documents, packaging, routing and airline acceptance.

Battery cargo is not ordinary freight. Lithium batteries are Class 9 dangerous goods, and airlines scrutinise them far more closely than general cargo. Most problems we see — rejected bookings, delayed shipments, returned cartons — trace back to one of five things being wrong or missing before the cargo reaches airline acceptance.

Here is the sequence we follow for every battery air shipment from China.

Step 1

Confirm the UN classification

Everything else — documents, packaging, cost — flows from the classification.

Battery configuration	UN number	Class
Lithium-ion batteries shipped separately	UN3480	9
Lithium-ion batteries packed with or contained in equipment	UN3481	9
Lithium metal batteries shipped separately	UN3090	9
Lithium metal batteries packed with or contained in equipment	UN3091	9

The distinction matters: loose cells (UN3480) face stricter packing instructions and state-of-charge limits than batteries contained in equipment (UN3481). If you are unsure which applies, send the product specification — we determine the classification from the actual configuration, not the product name.

Step 2

Prepare the documents

For most lithium battery air shipments you will need:

UN38.3 Test Summary — proof the battery model passed the UN transport tests
MSDS / SDS — chemistry, hazards and handling information
Battery specification — model, voltage, capacity, watt-hours, cell count
Dangerous Goods Declaration (DGD) — for shipments that require one
Commercial invoice & packing list — export documentation

Have these reviewed before booking. A mismatch between the MSDS, the spec sheet and the actual labels is one of the most common reasons battery cargo stalls at acceptance.

Step 3

Packaging, marking & labelling

Air transport of batteries is unforgiving on packaging. Depending on the configuration, requirements can include:

IATA-compliant inner packaging with short-circuit protection
Rigid outer packaging with sufficient strength
Class 9 hazard label and lithium battery mark on each outer carton
State-of-charge limits for certain loose-cell shipments
Quantity limits per package according to the packing instruction

We check packaging and labels against the applicable packing instruction before the cargo is presented for acceptance.

Quick self-check before you book

Do I know the UN number?
Do I have the UN38.3 summary for this exact model?
Does the MSDS match the battery spec?
Are the Wh ratings marked on the cartons?
Do I know the destination's import requirements?

If any answer is no, resolve it before booking — not at the airline counter.

Step 4

Choose the right route

South China offers three practical gateways: Hong Kong (HKG), Shenzhen (SZX) and Guangzhou (CAN). The right choice depends on the battery configuration, the airline's acceptance policy, the destination and cost.

Small, eligible shipments → international express (DHL / UPS / FedEx), door-to-door
Larger commercial quantities → consolidated DG air freight
Complex configurations → direct DG air freight with dedicated handling

Transit time is confirmed per shipment — it is not a fixed promise, because DG and battery cargo can require additional handling or acceptance procedures.

Common reasons battery cargo is rejected at acceptance

UN38.3 summary missing or for a different model
MSDS contradicts the packaging or labels
Wrong UN number declared for the actual configuration
State of charge or quantity limits exceeded
Labels or lithium marks missing or incorrect

Takeaways

Key takeaways

Classify first

The UN number drives everything else. Confirm it from the actual configuration.

Documents before booking

UN38.3, MSDS/SDS and the spec sheet must match each other and the cargo.

Route to the cargo

Express for small eligible shipments; DG air freight for commercial quantities.
