Products classified under HTS 2815.20.00
Caustic Potash Flakes 90%
Potassium hydroxide in flake form with 90% purity, commonly used in industrial soap and detergent manufacturing. This chemically defined inorganic compound falls under HTS 2815.20.00 as it is a pure potassium hydroxide product meeting Chapter 28 definitions for alkali hydroxides. It is supplied in moisture-resistant packaging to prevent deliquescence.
Industrial Caustic Potash Solution 50%
A 50% aqueous solution of potassium hydroxide used in chemical synthesis and pH adjustment in water treatment. Classified under HTS 2815.20.00 as chemically defined potassium hydroxide, distinct from sodium hydroxide or peroxides in the heading. Supplied in HDPE drums for safe handling of this corrosive liquid.
Caustic Potash Pearls 98% Purity
High-purity (98%) potassium hydroxide pearls for pharmaceutical and biodiesel production applications. This form meets 'chemically defined' criteria of Chapter 28 Note 1, specifically classified under 2815.20.00 for potassium hydroxide excluding peroxides. Pearls offer better handling than flakes with reduced dust.
Technical Grade Caustic Potash 92% Flakes
Technical grade 92% potassium hydroxide flakes for pulp and paper bleaching processes. Falls squarely under HTS 2815.20.00 as a basic inorganic compound of potassium without organic modification. Packaged in 25kg bags with anti-caking agents.
Pharmaceutical Potassium Hydroxide Pellets
USP-grade potassium hydroxide pellets for medicinal tablet manufacturing and extraction processes. Chemically defined per Chapter 28 standards, specifically HTS 2815.20.00 for pure KOH. Low impurity levels (<10ppm heavy metals) ensure compliance with pharmacopeia.
Caustic Potash Liquid 45% for Biodiesel
45% potassium hydroxide solution optimized for transesterification in biodiesel production. Classified as chemically defined potassium hydroxide under HTS 2815.20.00, not as organic derivative. Supplied in isotanks for bulk industrial delivery.
Battery Grade Caustic Potash Solution
High-purity potassium hydroxide solution for alkaline battery electrolyte formulation. Meets HTS 2815.20.00 as chemically defined inorganic base, essential component before mixing. Low carbonate content (<0.5%) prevents battery gassing.
Caustic Potash Microprills 95%
Microprill form of 95% potassium hydroxide for easy dissolution in detergent formulations. This physical form of chemically pure KOH is classified under HTS 2815.20.00 per Chapter 28 definitions. Reduced particle size improves mixing efficiency.
Food Processing Caustic Potash 99%
FCC-grade 99% potassium hydroxide for food processing equipment cleaning and cocoa processing. Meets strict purity standards for food contact, classified under HTS 2815.20.00 as chemically defined compound. Low mercury/arsenic levels per FDA specs.
Caustic Potash Briquettes for Metallurgy
Briquetted potassium hydroxide for molten salt baths in metal heat treatment and aluminum processing. Formed for high-temperature stability, still chemically defined KOH under HTS 2815.20.00. Density optimized for furnace applications.
