For a Bluetooth speaker containing a lithium battery, buyers should obtain a UN 38.3 test summary that identifies the cell or battery used in the ordered configuration and keep it available with the shipment documentation process. The summary is not interchangeable with a generic safety certificate or an unrelated battery report.
What should the summary identify?
IATA guidance illustrates the information expected in a test summary under subsection 38.3.5, including manufacturer, test laboratory, report reference, test date, battery description, model numbers, performed tests, applicable standard and signature. The project file should also link the battery identity to the finished speaker bill of materials.
Buyer matching checklist
| Field | Match against | Reject or clarify when |
|---|---|---|
| Battery model | Specification, BOM, label and physical sample | Model is absent or different |
| Manufacturer | Cell/battery supplier record | Only a trader name is shown without traceability |
| Report reference and date | Test summary and underlying report reference | Reference is missing or unreadable |
| Physical description and rating | Ordered pack construction and Wh rating | Series/parallel layout or rating differs |
| Test list and result | Applicable UN Manual revision and battery type | Tests or applicability are unclear |
Shipment review is separate
Passing the UN 38.3 test sequence does not by itself define every packaging, marking, documentation, state-of-charge or carrier requirement for a shipment. The shipper should classify the battery and equipment configuration, apply the current modal rules and confirm carrier or state variations.
Change control
A battery supplier, cell, chemistry, protection board, pack layout or rating change can break the link between the approved sample and existing records. Require written change notification and repeat the transport-document review before production release.
