Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If primarily copper oxide rather than hydroxide
Copper oxides fall under the separate subheading 2825.50.10 within the same copper oxides and hydroxides heading, based on chemical composition.
If prepared as copper sulfate instead
Copper sulfate, a metal salt, is classified under heading 2833 for copper salts, not hydroxides, per Chapter notes limiting 2825 to oxides and hydroxides.
If formulated as a ready-to-use fungicide
Pesticides containing copper hydroxide as active ingredient are classified in Chapter 38 for disinfectants, not pure chemical compounds.

Import Tips & Compliance
• Verify purity and chemical definition per Chapter 28 Note 1 to ensure classification as copper hydroxide, not oxide
• Provide lab analysis certificates for customs to distinguish from organic complexes
• Watch for contamination that could shift to heading 2842 for complex salts
