UN 38.3, Test Summaries and Battery Shipping Documents

UN 38.3 test summary vs SDS/MSDS: which document do you need?

These records support different checks; they are not five universally mandatory shipping attachments. The transport file needs several records with different owners and purposes. A document is useful only when its battery model, electrical rating and physical pack match the goods being offered to the carrier.

IATA FAQ G.01 states that its DGR does not require an SDS for batteries offered for transport. A supply-chain request is a separate matter; clarify who needs it and why.

The eight transport tests

Applicability differs for cells and batteries. Use the current UN Manual of Tests and Criteria.

Air-cargo planning: batteries, equipment or vehicles?

For lithium-ion air cargo, assess the shipment below.

A complete e-bike is not ordinary equipment by default. A dangerous-goods specialist must confirm classification, packing and carrier acceptance. Check other transport modes separately.

Match documents to the physical pack

1. Record model, voltage, capacity, Wh and chemistry.
2. Record cell maker/model and series-parallel layout.
3. Match the pack to the test summary.
4. Review cell, BMS, enclosure and interconnection changes.
5. Check mass, package quantity and gross weight.
6. Verify isolation, cushioning and activation protection.
7. Get carrier acceptance before dispatch.

Returns need a separate plan

• Current SDS and battery specification.
• Package and shipment documents.
• Marks, labels and emergency contact.
• Local isolation, diagnosis and disposal process.

Damaged, defective or recalled batteries often cannot use ordinary return channels.

Control packaging and handover evidence

Photograph terminal protection, cushioning, orientation, inner packaging, outer carton, marks and labels before the pilot shipment closes. Compare the photographs with the packing instruction and tested package. Record who packed, checked and released the consignment. At handover, the forwarder should confirm classification, mode, routing restrictions and required originals rather than discovering a mismatch at the airport.

Audit all ten elements of the UN 38.3 test summary

Subsection 38.3.5 of the UN Manual requires the test summary to be made available. A buyer should check the content rather than accepting a file named “UN38.3.pdf.” The summary should contain:

1. the cell, battery or product manufacturer name;
2. manufacturer contact information, including address, phone, email and website;
3. the test laboratory name and contact information;
4. a unique test-report identification number;
5. the date of the test report;
6. a battery description including lithium-ion or lithium-metal type, mass, Wh rating or lithium content, physical description and model numbers;
7. the list of tests conducted and pass/fail results;
8. the assembled-battery references where applicable;
9. the edition and amendment of the UN Manual used; and
10. the signatory name, title and signature confirming validity.

The eight test families commonly referenced are altitude simulation, thermal, vibration, shock, external short circuit, impact or crush, overcharge and forced discharge. Which tests apply differs between cells and batteries. The summary is a structured index; the report is the technical evidence behind it.

Reference the current UN Manual of Tests and Criteria, Revision 8 and amendments when defining the evidence requested from the battery supplier.

Decide whether a change creates a new battery type

Transport evidence is configuration-specific. A cell change, electrode or electrolyte change above the Manual’s thresholds, pack topology change, protective-device change or another modification that could materially affect test results may require a new-type assessment and retesting. Procurement teams should not allow an “equivalent cell” substitution without a documented engineering and transport review.

Classify the actual consignment before requesting a freight quote

A vehicle with spare batteries needs separate assessment; one package does not make it UN 3481. See the 2026 IATA guidance, vehicle section and FAQ F.13. This guide is not shipment approval.

For 2026 air planning, use the current IATA lithium-battery resources and have a trained dangerous-goods specialist confirm the packing instruction and carrier variation. Do not copy a previous shipment simply because the nominal voltage and capacity look similar.

Plan damaged, returned and prototype batteries separately

Standard production transport documents should not be reused automatically for damaged, defective, recalled, waste or prototype batteries. These cases may be prohibited on a planned mode or require special approval, packaging and competent-authority involvement. Define the after-sales decision tree before launch: remote diagnosis, safe isolation instructions, local repair, part replacement, collection route and escalation contact.

Jimsen can prepare project-specific battery specifications, coordinate requested testing and shipping evidence, and provide video diagnosis, replacement parts and technical guidance under the agreed warranty plan. Final dangerous-goods acceptance remains route- and carrier-specific and should be confirmed for each shipment.
