This product may fall under a more specific subheading:
Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If converted to niobium oxide chemical
Purified Nb2O5 classifies as metal oxides in Chapter 28 rather than raw ore.
If ferroniobium master alloy
Niobium combined with iron for steelmaking becomes Chapter 72 ferroalloys.
If associated with coarse iron ore particles
Statistical note defines coarse iron ores; niobium-bearing magnetites may dual-classify.

The Tariff Assistant works through the GRI rules on your specific product to reach the right HTS code — and can price the duty on it in the same conversation.
Import Tips & Compliance
• Verify minimum 60% Nb2O5 equivalent for proper ore classification vs. lower-grade materials
• Register under TSCA for chemical substances and prepare exposure assessments
• Monitor Brazilian export quotas, as they impact global niobium supply availability
