Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If pre-incorporated into lithium-ion battery components
Battery parts containing cobalt compounds classify as electric accumulators in Chapter 85.
If inorganic pigments containing cobalt sulfate
Coloring matter prepared as pigments falls under 3206, not base chemicals.
If as battery chemical preparation
Mixtures for battery production are chemical preparations in 3824, excluding pure salts.

Import Tips & Compliance
• Submit spectrographic analysis showing >90% CoSO4 equivalence to meet 'chemically defined' criteria
• Declare battery-grade specs if applicable, but avoid pre-mixed electrolyte classification
• Check for anti-dumping duties on cobalt chemicals from specific origins
