UN-Certified Battery Packaging Service

May 09, 2026

We do more than provide boxes. Our DG team reviews the battery type, UN number, watt-hour rating, state of charge, documents, packaging method, labels, and destination requirements before cargo is booked, so the shipment is less likely to be rejected by the warehouse, airline, ocean carrier, customs broker, or final-mile network.

What Battery Shipments We Can Pack and Handle

We support compliant packaging and forwarding for common lithium battery cargo, including standalone cells, battery packs, batteries packed with equipment, batteries contained in equipment, power banks, e-bike batteries, energy storage modules, industrial electronics, consumer electronics, and battery-powered devices.

Typical classifications include:

Cargo typeCommon UN numberExamples
Lithium-ion batteries shipped aloneUN3480Battery packs, power bank cells, replacement rechargeable batteries
Lithium-ion batteries packed with equipmentUN3481Devices shipped with spare batteries in the same carton
Lithium-ion batteries contained in equipmentUN3481Electronics, tools, meters, medical devices, smart products
Lithium metal batteries shipped aloneUN3090Primary lithium cells and non-rechargeable batteries
Lithium metal batteries packed with or contained in equipmentUN3091Devices using lithium metal cells
Battery-powered vehicles or equipmentUN3171E-bikes, scooters, battery-powered machines where applicable
Large battery installations or cargo transport unitsUN3536Special large-format battery shipments when classification applies

Normal commercial batteries, damaged batteries, defective batteries, recalled batteries, prototype batteries, and used batteries are not handled the same way. If the cargo is swollen, leaking, overheating, returned from market, involved in an incident, or being recalled, it must be reviewed separately before acceptance.

What Is Included in the Packaging and Labeling Service

Our service covers the practical work required before a lithium battery shipment can move safely through a DG freight channel:

  • Battery classification review by chemistry, configuration, Wh rating, and UN number
  • UN-spec outer packaging selection where required
  • Inner protection to prevent short circuit, movement, crushing, or terminal contact
  • Cushioning, separators, insulation, and void filling based on cargo risk
  • Correct Class 9 dangerous goods label and lithium battery mark
  • Cargo Aircraft Only label where air transport rules require it
  • Carton marking with UN number, consignee/shipper details, and handling marks
  • Packaging photo review before freight booking
  • DG document check before export customs and carrier submission
  • Door-to-door freight coordination under DDP, DDU, FOB, or CIF terms

This makes the service useful for China suppliers that can manufacture batteries but cannot prepare them to airline, ocean, warehouse, or destination customs expectations.

Why Correct Battery Packaging Prevents Rejections

Lithium battery shipments are frequently delayed or refused because the cargo is not presented correctly. A factory carton may look strong enough for ordinary export, but DG shipping requires more than normal packaging.

Common rejection reasons include:

Rejection riskWhat can go wrongHow proper packing helps
Wrong UN numberCarrier books the shipment under the wrong DG entryClassification is checked before booking
Weak inner protectionBatteries move, terminals contact, or packs are crushedSeparators, insulation, cushioning, and anti-movement packing are added
Missing Class 9 labelWarehouse or carrier refuses acceptanceCorrect DG labels are applied before handover
Missing lithium battery markShipment may be treated as undeclared or incompleteRequired marks are placed visibly on the outer package
High state of chargeAir cargo may fail acceptance rulesSoC is checked against the transport mode
Poor documentsCustoms or carrier requests correctionMSDS, UN38.3, invoice, packing list, and DG declaration are aligned

For broader transport planning beyond packaging, our lithium battery shipping service covers freight options from China to major destination markets.

UN Classification, Marks, and Compliance Checks

Lithium battery packaging starts with classification. The same product can fall under different transport entries depending on whether the battery is shipped alone, packed with equipment, or installed inside equipment.

For air freight, IATA DGR and ICAO rules are central. For sea freight, shipments follow IMDG Code requirements. The shipment may also require a Shipper’s Declaration for Dangerous Goods, UN38.3 test summary, MSDS/SDS, and correct packing instruction review.

Key compliance checks include:

  • Lithium-ion vs lithium metal chemistry
  • Cell or battery configuration
  • Watt-hour rating for lithium-ion batteries
  • Lithium content for lithium metal batteries where relevant
  • Net battery weight per package
  • Whether batteries are standalone, packed with equipment, or contained in equipment
  • State of charge, especially for air transport
  • Passenger aircraft restriction and Cargo Aircraft Only marking
  • Whether the shipment is normal, damaged, defective, recalled, or waste cargo

Standalone lithium-ion batteries shipped by air are commonly subject to a 30% state-of-charge limit. Other battery configurations may also have specific acceptance limits depending on packing instruction, carrier policy, and approval route. We confirm the practical requirement during shipment review rather than assuming every battery can move under the same mode.

Packaging Checklist Before Pickup or Warehouse Receiving

Before cargo reaches our China warehouse, send the shipment details for review. This helps avoid repacking delays and quote revisions.

Required detailWhy it matters
Battery chemistryConfirms lithium-ion, lithium metal, or other battery type
Product photosShows terminals, casing, equipment, and packing condition
Existing packaging photosHelps decide whether repacking is needed
UN38.3 test summary or reportSupports transport acceptance

Destination country and address typeConfirms USA, UK, Germany, EU, Canada, or Australia delivery planning
IncotermsConfirms DDP, DDU, FOB, or CIF service scope
Cargo conditionIdentifies normal, returned, damaged, defective, or recalled cargo

If batteries are damaged, leaking, swollen, burned, overheating, or suspected unsafe, use our dedicated damaged & defective lithium battery shipping route instead of treating them as normal cargo.

Shipping Modes, Lanes, and Lead-Time Guidance

The best mode depends on battery type, size, urgency, documents, destination, and carrier acceptance.

ModeBest forCompliance levelLead-time note
Air freightUrgent approved battery cargo, smaller shipments, commercial restockingStrictest acceptance, SoC and airline approval importantConfirmed by lane, airline, and DG approval

Our 5-Step Process: Pickup to Door Delivery

  1. Cargo and document review
    We check battery type, UN number, MSDS, UN38.3, photos, packing condition, quantity, weight, destination, and requested Incoterms.
  2. Pickup or warehouse receiving in China
    Cargo can be collected from the supplier or received at our China DG handling point for inspection, repacking, labeling, and document matching.
  3. DG packing and labeling
    The team applies suitable inner protection, outer packaging, lithium battery marks, Class 9 labels, UN markings, and other required handling labels.
  4. Export customs and freight booking
    Commercial invoice, packing list, DG declaration, and supporting documents are checked before the shipment is submitted to the approved air, sea, or door-to-door channel.
  5. Destination customs and final delivery
    Depending on the service term, we coordinate DDP or DDU clearance support and delivery to warehouse, business address, FBA-related destination, or final consignee.

Documents We Prepare and Check

Lithium battery shipments are document-sensitive. A shipment with good packaging can still be delayed if documents do not match the cargo.

Common document requirements include:

  • UN38.3 test summary or test report
  • MSDS / SDS
  • Dangerous Goods Declaration or Shipper’s Declaration where required
  • Commercial invoice
  • Packing list
  • HS code and product description
  • Battery specification sheet
  • Packaging photos
  • Carton marks and label photos
  • Air transport identification report where required for China air export review
  • Importer details, tax/VAT/EORI details, or consignee information where destination customs require them

For recalled products, do not book as normal stock. Use the dedicated recalled battery shipping service so the return reason, safety condition, packaging route, and carrier acceptance can be reviewed correctly.

FAQ

What is included in a UN-certified battery packaging service?

It usually includes classification review, UN-spec outer packaging where required, inner insulation, terminal protection, cushioning, lithium battery marks, Class 9 labels, DG document checks, packaging photos, and freight booking support.

Which UN number applies to my lithium battery shipment?

Standalone lithium-ion batteries are commonly UN3480. Lithium-ion batteries packed with or contained in equipment are UN3481. Lithium metal batteries may be UN3090 or UN3091. Battery-powered vehicles may fall under UN3171. Final classification depends on the actual product and configuration.

Can you repack batteries already packed by my China supplier?

Yes, if the cargo is acceptable for handling and the documents support the shipment. We can review supplier packaging photos, inspect cartons, improve inner protection, add compliant marks and labels, and prepare the cargo for the selected freight mode.

What labels are required for lithium battery shipping?

Depending on the shipment, labels may include the Class 9 lithium battery label, lithium battery mark, UN number marking, orientation marks, handling marks, and Cargo Aircraft Only label for restricted air cargo. The exact label set depends on UN number, mode, and packing instruction.

Do I need UN38.3 and MSDS for battery freight?

In most commercial lithium battery shipments, UN38.3 and MSDS/SDS are expected for carrier, forwarder, and customs review. Some routes may also require a DG declaration, battery test summary, product datasheet, and packaging evidence.

Can damaged, defective, or recalled batteries use the same packing route?

Not always. Damaged, defective, leaking, swollen, returned, waste, or recalled batteries need separate DG risk review and may face stricter mode restrictions. They should not be mixed with normal commercial battery cargo without approval.
