When sourcing LiFePO4 and lithium-ion batteries for industrial, commercial or residential projects, certifications are the difference between a safe, insurable, import-compliant product and a liability. This page explains the key marks B2B buyers should verify.

Core lithium-battery certifications

  • UN38.3 — mandatory transport-safety testing for all lithium batteries (air, sea, road). No UN38.3, no legal shipment.
  • IEC 62619 — industrial and stationary battery safety (the global benchmark for ESS).
  • IEC 62133 — safety for portable cells and batteries.
  • CE — EU declaration of conformity for the European market.
  • UL 1642 / UL 9540 — North American cell and energy-storage-system safety standards.
  • RoHS — restriction of hazardous substances.
  • IP rating — ingress protection for marine, outdoor and industrial duty (e.g. IP67 for Coremax marine batteries).

Why certification matters for buyers

  • Safety & liability — certified cells reduce thermal and electrical risk.
  • Import & compliance — many markets block uncertified lithium shipments.
  • Bankability — ESS and solar incentives often require recognised standards (IEC/UL).

What to request from a supplier

Ask for the actual test reports and certificate copies (not just a logo on the case), the applicable standard per market, and the battery management system (BMS) specifications. Coremax manufactures to international transport and safety standards and can provide its certification package and first-party test data on request.
