Overview

This HTS category, 2815.20.00.90, encompasses potassium hydroxide (caustic potash) in forms other than solid. Potassium hydroxide is a strong base, widely used in various industrial applications including the manufacture of soaps and detergents, fertilizers, batteries, and in petroleum refining. Its chemical properties make it an essential reagent in numerous chemical processes.

This classification is specifically designated for potassium hydroxide that is not presented in a solid form, distinguishing it from its sibling category, 2815.20.00.50, which covers potassium hydroxide in solid form (e.g., flakes, pellets, or blocks). Therefore, this category would include liquid solutions of potassium hydroxide, such as aqueous solutions of varying concentrations, or potentially potassium hydroxide incorporated into other non-solid matrices where its primary identity remains as caustic potash.

As this is a leaf node within the HTS, there are no further subcategories. Classification into this specific code is determined by the physical state of the potassium hydroxide, requiring customs professionals to verify that the product is not in a solid form to ensure accurate tariff assignment.
