Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If incorporated into finished lithium-ion battery cells
Assembled batteries classified by function in Chapter 85, not raw oxides.
If prepared as inorganic pigment for paints
Luminophore or finished pigments under 3206 per Chapter 28 note exclusions.
If doped for semiconductors or in wafer form
Doped chemical elements in disc/wafer forms shift to 3818 per Chapter 28 notes.

Import Tips & Compliance
• Provide assay reports showing >99% Co3O4 to distinguish from commercial oxides
• Battery-grade requires REACH compliance docs if from EU; watch for anti-dumping on Chinese origins
• Label as 'not for alloy use' to prevent shift to Chapter 81
