Product classification

HS code for Potassium chlorate: 2829.19

Chlorates, other than sodium.

Classification of potassium chlorate under HS 2829.19

Potassium chlorate is classified under HS code 2829.19. This code is part of Chapter 28, which covers inorganic chemicals. Heading 2829 is dedicated to chlorates and perchlorates, bromates and perbromates, and iodates and periodates. Within this heading, the subheadings are divided between sodium chlorate (2829.11) and "other" chlorates (2829.19). Since potassium chlorate is not sodium chlorate, it falls into the "other" category. Potassium chlorate is a strong oxidizing agent used in the manufacture of matches, explosives, and pyrotechnics. Its classification is based on its chemical identity as a salt of chloric acid. Because of its hazardous nature as an oxidizer, it is strictly regulated, and the HS code 2829.19 is used by customs authorities to monitor shipments for safety and security compliance, particularly regarding the precursors for explosives.

Codes often confused with 2829.19

Common mistake. The most common misclassification is 2829.11, which is specifically for sodium chlorate. While they share similar properties and uses, the HS system distinguishes them at the 6-digit level. Another misclassification occurs under 3604.90, which covers pyrotechnic articles. If potassium chlorate is imported as a component of a finished firework or signal flare, it belongs in Chapter 36. However, as a raw chemical substance, it must be classified in 2829.19. It is also sometimes confused with potassium chloride (2827.39), though the two chemicals have very different properties and oxygen content.

How these figures are built

109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries marked * did not, so their figures add up what other countries recorded trading with them, and their exports are valued at buyers' CIF prices. 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).
