2805.12.00.00 - Calcium 🖩

This HTS classification, 2805.12.00.00, specifically covers elemental calcium. Calcium is an alkaline-earth metal, characterized by its silvery-white appearance and its chemical properties as a reactive metal. It is typically found in its pure form or as a constituent in alloys. This classification applies to calcium regardless of its physical state, whether it is in powder, lump, or other forms, as long as it is not combined with other elements to form compounds that would be classified elsewhere.

This category is distinguished from its sibling, 2805.11.00.00, which exclusively covers elemental sodium. While both sodium and calcium are alkali and alkaline-earth metals, they are distinct chemical elements with differing properties and industrial applications. The sibling category 2805.19.00.00, "Other," would encompass any alkaline-earth metals not otherwise specified in the preceding subheadings, such as magnesium or strontium, further delineating the scope of this specific classification for calcium.

As this is a leaf node, there are no further subcategories under 2805.12.00.00. Therefore, the focus for classification purposes within this HTS code is solely on identifying and verifying that the imported or exported product is indeed elemental calcium. Classification relies on the purity of the substance and the absence of chemical combinations that would place it in a different chapter, such as compounds of calcium.
