Solar container battery level classification

What is a shipper's declaration for lithium ion batteries – 2025 OSS/cargo?

By signing the Shipper’s Declaration, the shipper is making a legal statement that all the applicable provisions of the DGR have been complied with, which includes that the lithium ion batteries are at no more than 30% SoC. This declaration is part of the IATA Guidance Document for Lithium Batteries and Sodium ion Batteries – 2025 OSS/Cargo.

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.

What are the different types of lithium batteries?

Lithium batteries fall into two broad classifications: lithium metal batteries and lithium-ion batteries. This is according to the IATA Guidance Document for Lithium Batteries and Sodium ion Batteries – 2025.

What is a state of charge (SOC) for lithium ion batteries?

For lithium ion batteries (UN 3480), the state of charge (SoC) must not exceed 30% of their rated capacity when shipped.

What is the ICAO guidance document for lithium ion batteries?

The ICAO Technical Instructions for the Safe Transport of Dangerous Goods by Air (Technical Instructions) provides guidance on the transport of lithium ion batteries. The 2025-2026 Edition of these instructions is the most recent version.

What are the key standards for lithium ion cells?

Here’s a breakdown of key standards at each level: IEC 62619 and IEC 63056 ensure safety and performance for industrial lithium-ion cells. UL 1642 and UN 38.3 verify safety and transport compliance of lithium cells. RoHS and REACH (NPS) ensure environmental and chemical safety.
