HS Code for Nickel sulphate

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.

Products Included

• Anhydrous nickel sulphate
• Nickel sulphate hexahydrate
• Nickel sulphate heptahydrate
• Commercially pure nickel sulphate crystals
• Aqueous solutions of nickel sulphate (not mixed with other plating chemicals)

Common Misclassification

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).
