2827.60.20.00 - Of potassium

This category encompasses iodide and iodide oxide compounds specifically of potassium. These are inorganic chemical substances where potassium is the primary cation, combined with iodide anions or in an oxide form containing iodide. Examples include potassium iodide (KI) and potassium iodate (KIO3). These substances find applications in various industries, including pharmaceuticals, photography, and as food additives.

When classifying within the "Iodides and iodide oxides" heading (2827.60), it is crucial to differentiate this subcategory based on the metallic cation. This node, 2827.60.20.00, is exclusively for potassium-based compounds. It is distinct from the sibling category 2827.60.10.00, which covers iodides and iodide oxides of calcium or copper. Furthermore, it differs from the "Other" category (2827.60.51.00), which would include all remaining metallic iodides and iodide oxides not specifically enumerated.

As this is a leaf node within the HTS, there are no further subdivisions under 2827.60.20.00. Classification at this level is determined by the specific chemical identity of the iodide or iodide oxide compound, provided it contains potassium as the principal metallic component. The physical form, purity, and intended use are generally secondary to the chemical composition for classification purposes within this specific subcategory.
