HS Code for Potassium iodate

Potassium iodate is classified under HS code 2829.90, which specifically covers perchlorates, bromates, iodates, and periodates. This classification is determined by the chemical composition of the substance as an inorganic salt of iodic acid. According to the General Rules for the Interpretation (GIR) of the Harmonized System, specifically GIR 1, classification is determined by the terms of the headings and any relative section or chapter notes. Chapter 28 covers inorganic chemicals, and heading 2829 specifically addresses salts of oxometallic or peroxometallic acids of halogens. Potassium iodate (KIO3) fits this description perfectly as an iodate salt. The product is typically presented as a white crystalline powder and is widely used in the food industry for the iodization of table salt to prevent iodine deficiency disorders. It is also utilized in analytical chemistry as an oxidizing agent and in the manufacture of certain pharmaceuticals. The classification remains consistent regardless of the grade, whether it is food-grade, pharmaceutical-grade, or technical-grade, provided it is a separate chemically defined compound. If the product is mixed with other substances, such as anti-caking agents in high concentrations, it might be classified elsewhere, but pure potassium iodate is strictly 2829.90. The Explanatory Notes to the Harmonized System for heading 2829 confirm that this heading includes iodates of the formula MIO3. Potassium iodate is the most common commercial example of these salts. It is more stable than potassium iodide, which is why it is preferred for salt fortification in tropical climates. Proper documentation must specify the chemical purity to ensure the 2829.90 code is applied correctly by customs authorities globally.

Common Misclassification

Potassium iodate is frequently confused with potassium iodide, which falls under HS code 2827.60. While both are used for iodine supplementation, they are chemically distinct salts. It may also be misclassified under 2834.21 (potassium nitrate) due to similar crystalline appearances, though their chemical properties and acid radicals are entirely different.
