2812.14.00.00 - Phosphorous pentachloride

This HTS category, specifically HTS 2812.14.00.00, encompasses phosphorous pentachloride. Phosphorous pentachloride is an inorganic chemical compound with the formula PCl₅. It is a strong chlorinating agent and is primarily used in organic synthesis as a reagent for various chemical reactions, including the conversion of carboxylic acids to acyl chlorides and the chlorination of alcohols. Its solid form, typically white to yellowish crystalline powder, and its strong reactivity are key identifying characteristics.

This classification is distinct from its sibling categories by the specific chemical compound it represents. For instance, HTS 2812.13.00.00 covers phosphorous trichloride (PCl₃), which has a different chemical structure and reactivity profile. Similarly, HTS 2812.12.00.00 is for phosphorous oxychloride (POCl₃), another related but distinct phosphorous halide. The "pentachloride" designation specifically identifies the compound with five chlorine atoms bonded to a central phosphorus atom, differentiating it from compounds with fewer chlorine atoms.

As HTS 2812.14.00.00 is a leaf node within the tariff schedule, there are no further subcategories. Classification decisions at this level rely on the precise chemical identity and purity of the substance being imported or exported, ensuring accurate tariff application for this specific inorganic chemical.
