Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If as complex salts like niobates
Double or complex salts of niobium go to 2842 per Chapter notes, not pure oxides.
If as niobium ore or concentrates
Unrefined niobium-bearing materials are in Chapter 26, not refined oxides.
If for bulk industrial chemical preparations
If blended with additives exceeding simple oxide purity, it may fall under chemical mixtures.

Import Tips & Compliance
• Provide chemical analysis confirming NbO2 composition to distinguish from mixed oxides excluded by Chapter notes
• Label with CAS number (12035-37-3) and hazard info for DOT compliance during import
• Avoid pitfall of classifying as artificial graphite mixtures if carbon-doped (heading 3801)
