HS code for Potassium chromate: 2841.50
Salts, chromates, dichromates, peroxochromates, n.e.c. in heading no. 2841.
Classification of potassium chromate under HS 2841.50
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.

Codes often confused with 2841.50
Common mistake. 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.
Top exporters and importers of HS 284150 (the code used for potassium chromate), 2025
In 2025, the largest exporter of HS 284150 (the code used for potassium chromate) in UN Comtrade data was China, with 15% of world exports; the largest importer in UN Comtrade data was the United States, with 25% of world imports. Türkiye reports $969M of its chapter 28 exports without product detail (confidential), so its figure here may be too low and it may rank higher.
Figures cover everything classified under HS 284150, not only potassium chromate.

How these figures are built
109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries that did not report are estimated from what other countries recorded trading with them. Those estimates miss trade with other non-reporting countries, so they can be low, and a non-reporting country can rank higher than shown or be missing from the list. World totals add both and leave out trade between two non-reporting countries. Figures are in current US dollars; reported imports are mostly valued CIF and exports FOB, and exports include re-exports. The UN Comtrade links show the underlying records; they can also list a few reporters left out here (regional groups and older HS editions).
