HS Code 2833.24 – Sulphates; of nickel
HS code 2833.24 is the 6-digit subheading for sulphates, of nickel. It is used for nickel sulphate hexahydrate, anhydrous nickel sulphate, electroplating-grade nickel sulphate, battery-grade nickel sulphate and nickel ammonium sulphate.
What HS 2833.24 covers
Nickel sulphate is a significant inorganic chemical traded globally, primarily for its use in electroplating and as a precursor for other nickel compounds. It is a key component in nickel plating baths, providing a source of nickel ions for depositing a corrosion-resistant and decorative finish on various metal surfaces. Beyond electroplating, it's used in the production of catalysts, pigments, and in some battery technologies. Key players in its international trade include chemical manufacturers, electroplating companies, and battery producers. The global market is heavily influenced by the automotive, electronics, and construction industries, which rely on nickel-plated components. Trade often involves high-purity grades, with specifications critical for achieving desired plating quality. Environmental regulations regarding nickel discharge also play a role in its handling and trade.

Codes often confused with 2833.24
Common mistake. This code is specific to nickel sulphate. It can be confused with other nickel salts like nickel chloride (282735) or other sulphates if the specific cation (nickel) is not correctly identified.
Top exporters and importers of HS code 283324, 2025
In 2025, the largest exporter of HS code 283324 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).
