Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If used as inorganic pigment for paints
Chapter 28 note excludes luminophores and pigments classified ready for use in 3206.
If for supported catalysts on inert carriers
Catalyst preparations with nickel sulfate supported on substrates fall in 3815, not pure compounds.
If containing cobalt impurities >3%
Salts of cobalt/nickel mixtures classified as 'other' sulfates under 2833.29.

Import Tips & Compliance
• Provide lab assays confirming anhydrous state to distinguish from hexahydrate and prevent duty disputes
• Declare for pigment or catalyst end-use to expedite customs; hazardous material shipping labels required
• Avoid pitfall of classifying dry blends as 2833.24; impurities >5% may trigger 3824 reclassification
