Customs classification of lithium battery energy storage cabinets

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.

Common energy storage products include lithium-ion batteries, lead-acid batteries, and flow batteries, each having distinct HS codes. The HS code for lithium-ion batteries typically falls under 8507.60, whereas lead-acid batteries may also share similar classifications.

Revised Packing Instructions: More stringent requirements for UN-certified packaging, capable of withstanding specific drop tests. State of Charge (SoC) Emphasis: Increased scrutiny on the SoC for standalone lithium-ion battery shipments, with a general requirement not to exceed 30% of rated capacity.

The primary risk associated with the carriage of lithium-ion batteries is thermal runaway. This is a chemical reaction in which an increase in temperature within a battery cell causes a further, uncontrolled increase in temperature. This process can be initiated by manufacturing defects, physical damage, or overcharging. The consequences include:

UN 3536 - LITHIUM BATTERIES INSTALLED IN CARGO TRANSPORT UNIT. Robust Protection: BESS units must be housed in substantial, protective enclosures, often specially designed containers, to prevent physical damage and contain potential fires. IUMI highlights the risk of container damage impacting internal batteries.

SPECIFIC CUSTOMS CODE FOR ENERGY STORAGE The HS code that typically pertains to energy storage systems, particularly lithium-ion or lead-acid batteries, is 8507.60. This designation covers various types of batteries utilized in energy storage applications, playing a vital role in commercial and residential energy systems.
