When purchasing UN38.3-certified 18650 cells, ensure you obtain and verify the following compliance documents:
- UN38.3 Test Summary: Must include the cell model, manufacturer contact info, and pass status for all T.1–T.8 tests (e.g., altitude simulation, thermal cycling). Verify the lab credentials and test dates.
- IEC 62133-2 Report and CB Certificate: Required for end-device certification in many markets. Confirm the cell model matches your purchase.
- UL 1642 or UL 62133 Recognition: Necessary depending on your product’s target market and distribution channels.
- Safety Data Sheet (SDS): Provides handling and safety information.
- RoHS/REACH Statements: If applicable to your market’s environmental regulations.
- Quality Documents: Certificate of Conformance (CoC) per lot, plus factory process summaries covering OCV/IR aging and grading criteria.
These documents are not just formalities—they signal manufacturing discipline and reduce regulatory risks in your supply chain.
