HS code for Potassium perchlorate: 2829.90

Perchlorates, bromates and perbromates, iodates and periodates.

Classification of potassium perchlorate under HS 2829.90

Potassium perchlorate is classified under HS code 2829.90. This classification falls under heading 2829, which encompasses chlorates and perchlorates; bromates and perbromates; iodates and periodates. Within this heading, the subheadings 2829.11 and 2829.19 are reserved for chlorates of sodium and other chlorates, respectively. Consequently, perchlorates, including the potassium salt, are categorized under the "Other" subheading, 2829.90. The classification is based on the chemical's nature as an inorganic salt of perchloric acid (HClO4). Potassium perchlorate is a powerful oxidizing agent used extensively in the pyrotechnics industry, ammunition, and rocket propellants. As a separate chemically defined compound, it is correctly placed in Chapter 28. The high oxygen content and specific chemical structure distinguish it from other halides or simpler oxides, necessitating its placement within the perchlorate group.

Codes often confused with 2829.90

Common mistake. Potassium perchlorate is often misclassified under HS code 2829.19, which is for "other chlorates." While chlorates and perchlorates are related, they are chemically distinct (ClO3 vs ClO4), and the HS structure separates them at the subheading level. Another common misclassification is under HS code 3604.90, which covers pyrotechnic articles. While potassium perchlorate is a component of fireworks, the raw chemical itself must be classified in Chapter 28, not as a finished pyrotechnic product.

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).
