Product classification
HS code for Nickel sulphate: 2833.24
Sulphates, of nickel.
Classification of nickel sulphate under HS 2833.24
Nickel sulphate is classified under HS code 2833.24. This code falls within Chapter 28, which covers inorganic chemicals, precious metals, and rare-earth metals. Specifically, heading 28.33 is dedicated to sulphates, alums, and peroxosulphates. Nickel sulphate is a chemical compound with the formula NiSO4, commonly found in anhydrous form or as various hydrates, such as the hexahydrate or heptahydrate. Its classification is straightforward under the specific subheading 2833.24, which is reserved for sulphates of nickel. This classification applies to the chemical in its pure form or as a commercially pure grade. The Harmonized System requires that chemicals in Chapter 28 be separate chemically defined compounds, whether or not containing impurities. If the nickel sulphate is part of a prepared mixture, such as a ready-to-use electroplating bath containing additives like brighteners, buffers, or wetting agents, it may be classified elsewhere in Chapter 38. However, the bulk chemical used as a precursor in various industrial processes, including battery manufacturing and electroplating, remains strictly under 2833.24.

Codes often confused with 2833.24
Common mistake. Nickel sulphate is often misclassified under HS code 3824.99, which covers miscellaneous chemical products and preparations. This usually occurs when the product is a specialized plating solution rather than the pure chemical. Another error involves HS code 2833.29, which is the "other" category for sulphates; however, since nickel has its own specific subheading (2833.24), the use of the general category is incorrect. It should also not be confused with nickel oxides (2825.40) or nickel chlorides (2827.35).
Top exporters and importers of HS 283324 (the code used for nickel sulphate), 2025
In 2025, the largest exporter of HS 283324 (the code used for nickel sulphate) in UN Comtrade data was Indonesia, with 47% of world exports; the largest importer in UN Comtrade data was China, with 58% of world imports. Countries that did not report 2025 data are estimated from partner records, which can understate them.

How these figures are built
109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries marked * did not, so their figures add up what other countries recorded trading with them, and their exports are valued at buyers' CIF prices. 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. UN Comtrade records Taiwan as "Other Asia, not elsewhere specified". Saudi Arabia's exports under that code are left out: they are far too large to be trade with Taiwan, so mostly undisclosed partners. 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).
