Lithium battery solar container cabinet transportation requirements and standards

What are the classification and shipping requirements for lithium-ion batteries?

The classification and shipping requirements for lithium-ion batteries depend on their size and energy capacity (Watt-hours). For standalone batteries. Strict UN-certified packaging. IUMI strongly supports the SoC limit of 30% for air freight and advocates similar principles for maritime transport.

When should lithium-ion batteries be offered for transport?

Effective from 1 January 2025, it is recommended that lithium-ion cells and batteries are offered for transport at a state of charge not exceeding 30% of their rated capacity, or with an indicated battery capacity not exceeding 25%.

What are the packaging requirements for lithium batteries?

Packaging Requirements: Use UN-certified containers designed for lithium batteries, often made of non-combustible materials and equipped with safety features like smoke detectors and pressure vents. Ensure proper cushioning to prevent physical damage during transit.

Are lithium batteries safe to transport in 2025?

Transporting lithium batteries safely has become a global priority. You must understand the regulations governing this process in 2025 to prevent risks and ensure compliance. Over 40 air transport incidents involving lithium batteries have occurred since 1991, with 21 on passenger aircraft.

Are battery energy storage systems a threat to maritime safety?

12. March 2025 In recent years, demand for the maritime transportation of containerised Battery Energy Storage Systems (BESS) has grown significantly. However, due to the high safety risks associated with energy storage containers, their transportation poses new challenges to maritime safety.

What is the UN number for lithium battery energy storage?

Since storage equipment has lithium-ion battery inside, so most people assume the PSN shall be Lithium-ion batteries contained in equipment and the UN number shall be UN3481. However, with the development of lithium battery energy storage, more and more energy storage devices are being developed and applied.
