HS Code for Copper hydroxide
Copper hydroxide is classified under HS code 2825.50. Chapter 28 of the Harmonized System covers inorganic chemicals, precious metals, and rare-earth metals. Heading 2825 is designated for hydrazine and hydroxylamine and their inorganic salts, as well as other inorganic bases and metal oxides, hydroxides, and peroxides. Subheading 2825.50 specifically identifies copper oxides and hydroxides. This classification is based on the chemical identity of the substance. Copper hydroxide (Cu(OH)2) is an inorganic base and a metal hydroxide. It is distinct from copper salts of inorganic acids (which would fall under 2833 for sulfates or 2834 for nitrates) because it is a basic oxide/hydroxide. The classification remains consistent regardless of the grade (technical or pharmaceutical), provided the substance is a separate chemically defined compound and not mixed with other ingredients for a specific functional use like a retail-ready pesticide.

Common Misclassification
A common misclassification for copper hydroxide is HS code 3808.92, which covers fungicides. While copper hydroxide is frequently used as an active ingredient in fungicides, it only moves to Chapter 38 if it is prepared as a finished product (e.g., mixed with surfactants, carriers, or put up in retail packaging). If it is the pure chemical compound, it must stay in 2825.50. Another error is confusing it with copper sulfate (2833.25), which is a salt rather than a hydroxide.
FAQ
What is the HS code for copper hydroxide?
The HS code for copper hydroxide and copper oxides is 2825.50.
Does the purity level change the HS code?
Generally, no. As long as it is a separate chemically defined compound, it remains in 2825.50. However, if it is mixed with other substances for use as a pesticide, it moves to 3808.
