Heading 2833 — Sulphates; alums; peroxosulphates (persulphates)
Chapter 28: Inorganic chemicals
Plain-language overview
Use HS-6 283325 when importing or exporting copper sulphates, such as those used in agriculture as fungicides or in chemical processes. For example, a shipment of blue vitriol (copper(II) sulfate pentahydrate) fits this classification.
This code specifically covers sulphates derived from copper, distinguishing it from other sulphates like those of aluminum or iron, which fall under different HS codes. If you're dealing with copper sulphate for water treatment or as a feed additive, this is the correct classification.
When comparing to HS-6 283326, which covers copper sulphate in different forms or purity levels, ensure your product matches the specifications of HS-6 283325 to avoid classification errors. The distinction often lies in the chemical composition and intended use.
Understanding this classification is crucial for compliance with customs regulations, as misclassification can lead to delays or fines. Always check the purity and intended application of your copper sulphate to ensure proper HS code usage.
