HS Code for Zinc sulphate

Zinc sulphate is classified under HS code 2833.29. This code is located within Chapter 28, which encompasses inorganic chemicals, precious metal compounds, and radioactive elements. Heading 2833 is dedicated to sulphates, alums, and peroxosulphates. Because zinc sulphate is not specifically named in the preceding subheadings (such as those for sodium, magnesium, or aluminum sulphates), it falls into the residual category of 2833.29. The classification requires the product to be a chemically defined compound, regardless of its hydration state. Whether it is presented as a monohydrate, heptahydrate, or in its anhydrous form, it remains within this heading. This follows General Rules of Interpretation (GRI) 1 and 6, ensuring that the chemical identity takes precedence over the intended use unless the use is specifically defined by another heading in the nomenclature. In industrial contexts, zinc sulphate is often used in water treatment, as a mordant in dyeing, and in the production of rayon. For customs purposes, the purity and chemical structure are the primary factors in confirming 2833.29 as the correct code.

Products Included

Common Misclassification

Zinc sulphate is often misclassified under 3105.90 if it is packaged and sold specifically as a fertilizer. However, if it is a pure chemical, 2833.29 is correct. It may also be confused with 3004.90 if it is prepared as a medicament in measured doses for therapeutic use. Another common error is using 2833.19, which is reserved for sodium sulphates.

FAQ

What is the HS code for zinc sulphate?

The HS code for zinc sulphate is 2833.29, which covers other sulphates not specifically mentioned elsewhere in heading 2833.

Does the hydration state change the HS code?

No, whether the zinc sulphate is monohydrate or heptahydrate, it is still classified under 2833.29 as long as it remains a chemically defined inorganic compound.
