China export standards for Battery energy storage (BESS)

Battery energy storage systems store electrical energy in electrochemical cells and discharge it on demand, enabling grid stabilisation, behind-the-meter optimisation, and renewable integration. Exporting BESS from China involves layered compliance obligations: the cell chemistry must satisfy transport safety rules (UN 38.3), the module and rack must pass electrochemical safety standards (IEC 62619 or UL 9540), and in most markets an additional system-level certification—covering fire suppression, thermal runaway containment, and grid-interconnection behaviour—is mandatory before commissioning. Some markets also require local authority inspections or utility pre-qualification. The pages below map the complete approval chain, from cell-level test reports through to site commissioning requirements, for each market covered.
