Residential energy storage batteries, primarily lithium-ion types, are classified as hazardous goods during transportation due to risks of short circuits, leaks, thermal runaway, and even fires or explosions. Global transportation safety standards are governed by a unified framework of international regulations, including the UN Recommendations on the Transport of Dangerous Goods (TDG), UN Manual of Tests and Criteria (UN38.3), IATA Dangerous Goods Regulations (DGR) for air transport, IMDG Code for maritime transport, and RID for rail transport. These standards mandate strict testing, packaging, labeling, and documentation requirements to ensure end-to-end transportation safety.

UN38.3 is the foundational global test standard for lithium batteries, applicable to all residential energy storage batteries regardless of transport mode. It requires eight rigorous tests to simulate extreme transport conditions: altitude simulation (11.6kPa, 6 hours), temperature cycling (-40°C to 72°C, 10 cycles), vibration testing (10-55Hz, 3 hours), shock testing (100g, 6ms), external short circuit, impact/crush, overcharge, and forced discharge. Compliance with UN38.3 is mandatory for cross-border transport, with test reports issued by accredited laboratories (CMA/CNAS recognized). Additionally, regional standards like China’s GB/T 45915-2025 and EU’s REACH/RoHS directives impose supplementary restrictions on hazardous substances and packaging materials.

Packaging and labeling are critical for mitigating transport risks. Residential batteries must use UN-certified packaging (Class II/III) with shock-absorbent, fire-resistant, and leak-proof materials. Wooden packaging requires ISPM15 fumigation/heat treatment with IPPC marks. Outer packages must display clear labels: UN number (UN3480/UN3481 for lithium batteries), hazard class 9, "LITHIUM BATTERY" warning, and handling instructions. During transport, units must be secured to prevent movement. For air transport, IATA DGR restricts battery capacity and quantity, prohibiting damaged or defective units. Adherence to these standards ensures compliance, minimizes accident risks, and enables safe, efficient global logistics for residential energy storage batteries.
