7202.99.10.00 - Ferrozirconium

This classification covers ferrozirconium, an alloy of iron and zirconium. Ferrozirconium is primarily used as a deoxidizer and scavenger in the production of steel and other ferrous metals, helping to remove impurities and improve the properties of the final metal product. Its specific composition and intended metallurgical applications define its placement within the broader category of ferroalloys.

Within the "Other" subcategory of ferroalloys not elsewhere specified, ferrozirconium is distinguished from its siblings, such as calcium silicon (7202.99.20.00) and other unspecified "Other" ferroalloys (7202.99.80). The key differentiating factor is the presence and primary alloying element of zirconium in combination with iron, which dictates its unique metallurgical functions compared to other specialized ferroalloys or general miscellaneous ferroalloys.

As this is a leaf node, there are no further subcategories. The classification of ferrozirconium is therefore complete at this level, based on its identification as an alloy of iron and zirconium with specific industrial uses in metallurgy.
