Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If in the form of niobates or tantalates
Salts or complexes of niobium with acids fall under other niobium compounds, not pure oxides.
If doped for electronics and cut into wafers/discs
Per Chapter note, doped chemical elements in worked forms like discs shift to heading 3818.
If used as glass frit or powder for pigments
Chapter exclusions send inorganic powders for glass/coloring to Chapter 32.
