Product classification
HS code for Nickel-cadmium battery: 8507.30
Electric accumulators, nickel-cadmium, including separators, whether or not rectangular (including square).
Classification of nickel-cadmium battery under HS 8507.30
Nickel-cadmium (NiCd) batteries are classified under HS code 8507.30. This classification falls under Heading 8507, which encompasses electric accumulators, including separators, whether or not rectangular or square. According to the Harmonized System's Explanatory Notes, an accumulator is a device used for the storage of electrical energy which can be recharged by passing an electric current through it. The classification is determined by the chemical composition of the electrodes and the electrolyte. For NiCd batteries, the active materials are nickel hydroxide for the positive electrode and cadmium for the negative electrode. Because 8507.30 specifically names "nickel-cadmium" accumulators, it takes precedence over more general categories. This code applies to all formats of NiCd batteries, including sealed cells used in portable electronics and vented cells used in heavy industrial, rail, or aviation sectors. The inclusion of separators or the fact that the battery is part of a battery pack does not alter this classification, provided the chemistry remains nickel-cadmium.

Codes often confused with 8507.30
Common mistake. NiCd batteries are often confused with HS code 8506.10 or 8506.80, which cover primary (non-rechargeable) cells. Since NiCd batteries are secondary (rechargeable) cells, they must be under 8507. They are also frequently misclassified under 8507.50 (Nickel-metal hydride) or 8507.60 (Lithium-ion) due to similar physical appearances. It is critical to identify the specific chemistry marked on the battery casing to distinguish between these subheadings. Furthermore, spent or waste NiCd batteries should be classified under 8548.00 or 8549 depending on the specific regional adoption of the 2022 HS changes.
Top exporters and importers of HS 850730 (the code used for nickel-cadmium battery), 2025
In 2025, the largest exporter of HS 850730 (the code used for nickel-cadmium battery) in UN Comtrade data was Germany, with 18% of world exports; the largest importer in UN Comtrade data was the United States, with 9.6% 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 850730, not only nickel-cadmium 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-cadmium battery
What is the HS code for Nickel-cadmium battery?
The HS code for Nickel-cadmium battery is 850730 (Electric accumulators; nickel-cadmium, including separators, whether or not rectangular (including square)). The HS code for nickel-cadmium (NiCd) batteries is 8507.30.
How do I classify Nickel-cadmium battery for customs?
Nickel-cadmium battery is classified under HS code 850730 — Electric accumulators; nickel-cadmium, including separators, whether or not rectangular (including square). This is a 6-digit subheading level code.
Are NiCd battery separators classified separately?
No, if the separators are imported with the batteries or are part of the battery assembly, they are included under 8507.30. If imported alone, they are still generally classified under 8507 as parts of accumulators.
Which countries are the top exporters of nickel-cadmium battery (HS 850730)?
In 2025, the top exporters of HS 850730 (the code used for nickel-cadmium battery) in UN Comtrade data were Germany ($167M, 18% of world exports), France ($147M) and the United States ($143M). World exports came to about $922M, 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.
