Overview

This HTS category, 2835.26.00.00, encompasses "Other phosphates of calcium" not specifically enumerated elsewhere. These are inorganic chemical compounds where calcium is bonded with the phosphate anion (PO4³⁻), excluding those with precise descriptions under preceding subheadings. This classification includes various forms of calcium phosphates that do not fit the more specific descriptions of dicalcium phosphate (2835.25.00.00), which is commonly known as calcium hydrogenorthophosphate, or those directly identified as sodium or potassium phosphates.

The key differentiator for this subheading lies in its residual nature. It captures calcium phosphates that are not chemically defined as dicalcium phosphate. Classification relies on the chemical composition and the absence of a more specific HTS code. Examples might include tricalcium phosphate (Ca₃(PO₄)₂) or other complex calcium phosphate structures when not specifically listed.

As this is a leaf node within the HTS structure, there are no further subcategories to introduce. Therefore, classification within 2835.26.00.00 is definitive for any qualifying calcium phosphate that does not find its place in the more narrowly defined sibling categories. The focus for importers and exporters will be on accurately identifying the specific calcium phosphate compound and confirming it does not meet the criteria for 2835.25.00.00 or other related phosphate classifications.
