HS Code 8507.80 – Electric accumulators; other than lead-acid, nickel-cadmium, nickel-metal hydride and lithium-ion, including separators, whether or not rectangular (including square)

HS code 8507.80 is the 6-digit subheading for electric accumulators, other than lead-acid, nickel-cadmium, nickel-metal hydride and lithium-ion, including separators, whether or not rectangular (including square). It is used for sodium-ion batteries, solid-state batteries (prototypes), flow batteries, zinc-bromine batteries and silver-zinc accumulators.

What HS 8507.80 covers

This HS code is a residual category for electric accumulators (rechargeable batteries) that are not specifically classified as lead-acid, nickel-cadmium, nickel-metal hydride, or lithium-ion. This includes emerging battery chemistries and specialized types such as sodium-ion batteries, solid-state batteries (in development), flow batteries (e.g., zinc-bromine, vanadium redox), and other advanced or niche rechargeable systems. The international trade in these 'other' accumulators is often characterized by innovation, research and development, and specialized industrial applications where specific performance characteristics are required. Importers and exporters are typically companies involved in cutting-edge energy storage solutions, R&D institutions, or industries requiring highly customized power sources, reflecting a dynamic and evolving segment of the battery market.

Codes often confused with 8507.80

Common mistake. This code is for 'other' rechargeable batteries, so it's critical to ensure the battery does not fall under the more common lead-acid (850710/850720), NiCd (850730), NiMH (850750), or Li-ion (850760) categories.

How these figures are built

109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries that did not report are estimated from what other countries recorded trading with them. Those estimates miss trade with other non-reporting countries, so they can be low, and a non-reporting country can rank higher than shown or be missing from the list. World totals add both and leave out trade between two non-reporting countries. Figures are in current US dollars; reported imports are mostly valued CIF and exports FOB, and exports include re-exports. The UN Comtrade links show the underlying records; they can also list a few reporters left out here (regional groups and older HS editions).
