HS Code for Caustic potash
Caustic potash, chemically known as potassium hydroxide (KOH), is classified under HS code 2815.20. This code is part of the inorganic chemicals chapter and specifically identifies potassium hydroxide. Unlike sodium hydroxide, the HS code for potassium hydroxide does not distinguish between solid and liquid (aqueous solution) forms at the six-digit level. It is a strong alkaline substance produced through the electrolysis of potassium chloride. Its classification is straightforward as it is a chemically defined inorganic base. The Harmonized System groups it with other sodium and potassium hydroxides because of their similar chemical nature as strong alkalis used in industrial processes like soap making, biodiesel production, and as an electrolyte in alkaline batteries.

Common Misclassification
Sometimes confused with 2815.11 or 2815.12 (caustic soda) due to similar industrial uses and names. It may also be misclassified under 3824 if it is part of a complex chemical mixture, but pure KOH or KOH dissolved in water must remain in 2815.20 regardless of concentration.
