HS Code for Potassium chromate
Potassium chromate is classified under HS code 2841.50, which pertains to salts of oxometallic or peroxometallic acids, specifically chromates, dichromates, and peroxochromates. As an inorganic chemical, it falls under Chapter 28, which covers inorganic chemicals and precious metal compounds. This heading is structured to include various metal salts where the anion contains a metal and oxygen. Potassium chromate (K2CrO4) is a yellow crystalline solid used primarily as an indicator in analytical chemistry and in the manufacture of pigments, dyes, and textile mordants. The classification is determined by the chemical composition of the salt. Because it is a chromate of potassium and does not fall under the more specific subheadings for sodium or lead chromates, it is categorized under the "other" chromates section of 2841.50. The Harmonized System uses this classification to monitor the trade of chromium-based chemicals, which are often subject to environmental and safety regulations due to their toxicity. Proper classification ensures that customs authorities can apply the correct tariffs and safety protocols for hazardous materials.

Common Misclassification
It is often confused with HS code 2841.30, which is reserved for sodium dichromate, or HS code 2841.61, which covers potassium permanganate. Another common error is using 2841.20, which is specifically for chromates of zinc or lead. Accurate classification requires identifying both the cation (potassium) and the specific oxometallic anion (chromate). Misidentifying the metal cation is the most frequent cause of incorrect coding in this category.
