Ferrozirconium 70% Zirconium Grade
Ferrozirconium alloy containing approximately 70% zirconium and 25-30% iron, used primarily as a deoxidizer and grain refiner in steel production. Classified under HTS 7202.99.1000 as ferrozirconium, a ferroalloy not elsewhere specified in Chapter 72. It meets the definition of ferroalloys with zirconium as the principal alloying element.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If containing over 4% silicon by weight
Ferroalloys with silicon >4% fall under ferrosilicon heading regardless of other elements.
If chemically processed into a master alloy for specific steel grades
Further worked or chemically modified ferroalloys may classify as prepared binders or chemical products outside Chapter 72 ferroalloys.
If zirconium content exceeds 90% and marketed as pure zirconium
High-purity zirconium products shift from ferroalloys to Chapter 81 base metals of zirconium.

Import Tips & Compliance
• Obtain mill test certificates verifying zirconium content (>65%) to confirm classification as ferrozirconium
• Ensure proper hazardous material declarations if packaged in bags exceeding certain weights
• Common pitfall: misclassification as zirconium metal under Chapter 81 if iron content is too low
