Chemicals
View full HS code details

Blue vitriol, chemically known as copper(II) sulfate pentahydrate, is classified under HS code 283325. This classification is situated within Chapter 28, which covers inorganic chemicals and precious metal compounds. Heading 2833 specifically addresses sulphates, alums, and peroxosulphates. Within this heading, subheading 283325 is reserved for sulphates of copper. To qualify for this code, the substance must be a separate chemically defined compound, whether or not it contains impurities. Blue vitriol is widely used in industrial applications, including electroplating, pigment production, and as a laboratory reagent. The classification is strictly based on the chemical identity of the substance as a copper salt of sulfuric acid. If the product is presented as a mixture or a formulated preparation for specific uses, such as a fungicide, the classification may shift to other chapters, but the pure chemical form remains firmly under 283325. This code is essential for tracking chemical trade and ensuring compliance with safety data sheet (SDS) requirements for hazardous inorganic salts.

Common Misclassification

Blue vitriol is often misclassified under HS code 380892, which covers fungicides. While copper sulfate is a primary ingredient in many fungicides (like Bordeaux mixture), code 283325 only applies to the pure chemical. Once it is mixed with lime or other stabilizers for agricultural use, it moves to Chapter 38. It may also be confused with HS code 253090 for natural mineral substances if it is unrefined mineral ore, though blue vitriol is typically a manufactured chemical. Another potential error is HS code 283329, which is a \"basket\" category for other sulphates; however, copper sulphate has its own specific subheading at 283325.
