2835.24.00.00 - Of potassium

This HTS category, 2835.24.00.00, specifically covers phosphates that are compounds of potassium. Phosphates, in general, are salts or esters of phosphoric acid. The designation "of potassium" clearly indicates that the potassium cation is the primary metallic component forming the phosphate salt within this classification. These potassium phosphates can encompass various forms, including orthophosphates, polyphosphates, and metaphosphates, provided they are chemically defined and contain potassium.

This classification is distinguished from its sibling categories by the specific metal cation present. For instance, 2835.22.00.00 covers phosphates of mono- or disodium, while 2835.25.00.00 and 2835.26.00.00 pertain to various calcium phosphates. Therefore, the key differentiator for 2835.24.00.00 is the exclusive presence of potassium as the cationic element in the phosphate compound.

As a leaf node, this category does not have further subdivisions. The classification hinges on the precise chemical identity as a potassium phosphate. Examples within this classification might include dipotassium phosphate (K₂HPO₄), tripotassium phosphate (K₃PO₄), or tetrapotassium pyrophosphate (K₄P₂O₇), all of which serve various industrial applications such as food additives, fertilizers, or buffering agents. The classification would rely on documentary evidence confirming the chemical composition.
