Overview
This HTS category, 2850.00.05.00, specifically covers hydrides, nitrides, azides, silicides, and borides that are chemically defined and are composed of calcium. These compounds, while belonging to the broader group of inorganic chemicals, are distinct due to their specific elemental composition (calcium) and their chemical structure as binary compounds with hydrogen, nitrogen, azides, silicon, or boron. Their applications can range from high-temperature ceramics and metallurgical additives to specialized chemical synthesis.
Unlike its sibling categories, which classify similar binary compounds based on titanium (2850.00.07.00), tungsten (2850.00.10.00), or vanadium (2850.00.20.00), this subheading is exclusively concerned with those containing calcium. The "Other" category (2850.00.50.00) serves as a residual classification for such compounds not specifically listed with other metals.
As this is a leaf node in the HTS structure, there are no further subcategories. Therefore, classification within 2850.00.05.00 hinges on confirming the presence of calcium as the primary defining element in the hydride, nitride, azide, silicide, or boride compound, ensuring it is chemically defined and not a carbide under heading 2849.
