Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If niobium as unwrought metal or powder
Elemental niobium excludes iron alloys, classifying under Chapter 81 other base metals.
If containing specific rare earth elements
Ferroalloys with rare-earths like cerium have separate subheading 7202.99.10.
If rolled into bars for circular cross-section
When further worked into alloy steel bars, moves from raw ferroalloy to Chapter 72 finished shapes.
