China export standards for Sodium-ion battery storage (Na-ion)

Sodium-ion battery storage is an emerging electrochemical technology that substitutes sodium for lithium as the charge-carrying ion, offering potential advantages in raw material availability and low-temperature performance. Because the technology reached commercial scale only recently, dedicated international standards are still being developed; regulators in most markets currently apply lithium-ion frameworks—such as IEC 62619 and UL 9540—by analogy, sometimes requiring additional data packages to demonstrate equivalent safety under sodium-specific failure modes. Transport classification under UN 38.3 must also be established for each cell format. Exporters from China face uncertainty about which test protocols will be accepted and which bodies have relevant accreditation. The pages below document the current regulatory position and accepted testing routes for each market covered.
