2850.00.07.00 - Of titanium

This HTS category, 2850.00.07.00, specifically covers hydrides, nitrides, azides, silicides, and borides that are chemically defined and composed of titanium. These compounds, whether in their pure form or as alloys with other elements (excluding carbides of heading 2849), fall under this classification when titanium is the primary constituent or key component defining the compound. Examples include titanium nitride (TiN), titanium boride (TiB2), and various titanium silicides.

Distinguishing this category from its siblings is crucial. Unlike 2850.00.05.00 (of calcium), 2850.00.10.00 (of tungsten), and 2850.00.20.00 (of vanadium), this heading focuses exclusively on compounds where titanium is the defining metallic element. The "Other" category (2850.00.50.00) serves as a residual classification for compounds of this nature not specifically enumerated, such as those based on zirconium, hafnium, or other metals not listed in the preceding subheadings.

As a leaf node, this category has no further subdivisions. Classification within 2850.00.07.00 is determined by the presence of titanium as the principal element in the hydride, nitride, azide, silicide, or boride compound, adhering to the scope of heading 2850 which encompasses these specific inorganic chemical substances.
