HS code for Nickel-metal hydride battery: 8507.50
Electric accumulators, nickel-metal hydride, including separators, whether or not rectangular (including square).
Classification of nickel-metal hydride battery under HS 8507.50
Nickel-metal hydride (NiMH) batteries are classified under HS code 8507.50. This classification is part of Heading 8507, which covers electric accumulators. NiMH batteries are secondary (rechargeable) cells that utilize a nickel oxide hydroxide positive electrode and a hydrogen-absorbing alloy for the negative electrode. The classification is driven by GRI 1, as the subheading 8507.50 explicitly describes "nickel-metal hydride" accumulators. These batteries are widely recognized for their higher energy density compared to NiCd batteries and their lack of toxic cadmium, making them common in consumer electronics and hybrid electric vehicles. The HS code applies regardless of the battery's physical form—whether it is a button cell, a cylindrical cell, or a large-scale prismatic module used in automotive applications. As long as the battery is designed to be recharged and uses NiMH chemistry, it remains within this subheading. This also includes battery packs where multiple NiMH cells are connected together in a single housing.

Codes often confused with 8507.50
Common mistake. The most common misclassification for NiMH batteries is HS code 8507.30, which is reserved for nickel-cadmium batteries. While both are nickel-based rechargeable batteries, the metal-hydride component necessitates the use of 8507.50. Another common error is using 8507.80, which is the "other accumulators" category; however, since NiMH has its own specific subheading, 8507.80 should only be used for chemistries that do not have a dedicated code (like Silver-Zinc). Additionally, NiMH batteries should not be classified under 8506, as that heading is strictly for non-rechargeable primary cells.
Top exporters and importers of HS 850750 (the code used for nickel-metal hydride battery), 2025
In 2025, the largest exporter of HS 850750 (the code used for nickel-metal hydride battery) in UN Comtrade data was Japan, with 60% of world exports; the largest importer in UN Comtrade data was the United States, with 34% of world imports. Countries that did not report 2025 data are estimated from partner records, which can understate them.
Figures cover everything classified under HS 850750, not only nickel-metal hydride battery.

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).

Questions about nickel-metal hydride battery
What is the HS code for Nickel-metal hydride battery?
The HS code for Nickel-metal hydride battery is 850750 (Electric accumulators; nickel-metal hydride, including separators, whether or not rectangular (including square)). The specific HS code for nickel-metal hydride (NiMH) batteries is 8507.50.
How do I classify Nickel-metal hydride battery for customs?
Nickel-metal hydride battery is classified under HS code 850750 — Electric accumulators; nickel-metal hydride, including separators, whether or not rectangular (including square). This is a 6-digit subheading level code.
Can NiMH batteries be classified as parts of a machine?
Generally, no. Under Section XVI, Note 2, and Heading 8507, accumulators are classified in their own heading even if they are intended for use with a specific machine or vehicle.
Which countries are the top exporters of nickel-metal hydride battery (HS 850750)?
In 2025, the top exporters of HS 850750 (the code used for nickel-metal hydride battery) in UN Comtrade data were Japan ($1.2B, 60% of world exports), China ($309M) and Germany ($97M). World exports came to about $2.0B, adding countries' reported figures and partner-based estimates for those that did not report (UN Comtrade data). Countries that did not report 2025 data are estimated from partner records, which can understate them.
Which countries are the top importers of nickel-metal hydride battery (HS 850750)?
In 2025, the top importers of HS 850750 (the code used for nickel-metal hydride battery) in UN Comtrade data were the United States ($646M, 34% of world imports), Germany ($138M) and Mexico ($135M).
