7202.91.00.00 - Ferrotitanium and ferrosilicon titanium 🖩

This HTS category, 7202.91.00.00, specifically covers ferrotitanium and ferrosilicon titanium. These are master alloys primarily composed of iron and titanium, or iron, silicon, and titanium. They are produced by smelting titanium-containing ores with iron and/or silicon. Ferrotitanium is essential in steelmaking as a deoxidizer, denitridizer, and grain refiner, improving the mechanical properties of steel. Ferrosilicon titanium serves similar purposes, often offering enhanced deoxidizing capabilities due to the presence of silicon.

Within the broader category of "Other ferroalloys" (7202.9), this classification is distinguished by its specific focus on titanium-containing ferroalloys. Siblings like ferrovanadium (7202.92.00.00) are primarily alloys of iron and vanadium, used in the production of high-speed steels and other specialized alloys. Similarly, ferroniobium (7202.93) and other "other" ferroalloys (7202.99) represent distinct metallic compositions with different applications and metallurgical properties.

As this HTS code represents a leaf node, there are no further subcategories within 7202.91.00.00. Therefore, classification under this heading hinges entirely on the accurate identification of the product as ferrotitanium or ferrosilicon titanium, containing significant proportions of titanium, and intended for use as an additive in the production of iron and steel. The precise percentage composition, while not explicitly defined within the subheadings themselves, is a critical factor in distinguishing these alloys from other ferroalloys and must be supported by technical documentation.
