Products classified under HTS 2815.20.00.50
Industrial Grade Potassium Hydroxide Flakes
Potassium hydroxide in solid flake form, commonly known as caustic potash, used in industrial applications such as soap manufacturing and biodiesel production. This product falls under HTS 2815.20.00.50 because it is potassium hydroxide in solid form, meeting the chapter's criteria for inorganic bases in subchapter II. It is chemically defined and not excluded by chapter notes.
Caustic Potash 90% Pellets
High-purity potassium hydroxide pellets at 90% concentration in solid form, utilized in chemical synthesis and pH adjustment processes. Classified under HTS 2815.20.00.50 as it is explicitly potassium hydroxide in solid form, adhering to Chapter 28 definitions for inorganic compounds. Excludes any solution or mixed forms per tariff structure.
Technical Grade Caustic Potash Prills
Technical grade solid prills of potassium hydroxide used in water treatment and petroleum refining. Falls under HTS 2815.20.00.50 due to its solid form and classification as potassium hydroxide, aligning with Chapter 28's scope for chemically defined inorganic bases.
Pharmaceutical Grade Potassium Hydroxide Powder
Fine powder form of high-purity potassium hydroxide meeting USP standards for pharmaceutical applications like API synthesis. Classified in HTS 2815.20.00.50 as solid potassium hydroxide, excluded from Chapter 30 as it's an inorganic base per Section VI notes.
Battery Grade Potassium Hydroxide Briquettes
Ultra-pure solid potassium hydroxide briquettes designed for alkaline battery electrolyte production. This qualifies for HTS 2815.20.00.50 as potassium hydroxide in solid form, chemically defined per subchapter notes, and not covered by exclusions for electronics doping or mixtures.
Caustic Potash Microprills for Soap Making
Specialty microprills of potassium hydroxide optimized for small-scale soap and detergent production. This solid form product is under HTS 2815.20.00.50 as it matches the precise description of potassium hydroxide solids in Chapter 28.
