HS code for Sodium bromate: 2829.90
Perchlorates, bromates and perbromates, iodates and periodates.
Classification of sodium bromate under HS 2829.90
Sodium bromate is classified under HS code 2829.90. This heading covers chlorates and perchlorates, bromates and perbromates, and iodates and periodates. While sodium chlorate has its own specific subheading (2829.11), bromates are grouped into the "Other" category under 2829.90. Sodium bromate (NaBrO3) is a powerful oxidizing agent used primarily in the continuous dyeing process involving sulfur dyes and as a laboratory reagent. The classification follows the inorganic chemical guidelines of Chapter 28, which prioritizes the anionic component of the salt. Since it is an inorganic salt of bromic acid, it is excluded from the halides (2827) and is instead placed with other oxometallic salts of halogen acids in 2829.

Codes often confused with 2829.90
Common mistake. Sodium bromate is often misclassified under HS code 2827.51, which is for sodium bromide. The distinction is critical: 2827 covers bromides (salts of HBr), while 2829 covers bromates (salts of HBrO3). Bromates contain oxygen and act as oxidizers, whereas bromides do not. Another error is using 2829.11, which is specifically for sodium chlorate; although they are both oxidizers in the same heading, the halogen element (bromine vs. chlorine) necessitates the use of the 2829.90 "Other" category.
Top exporters and importers of HS 282990 (the code used for sodium bromate), 2025
In 2025, the largest exporter of HS 282990 (the code used for sodium bromate) in UN Comtrade data was India, with 22% of world exports; the largest importer in UN Comtrade data was Belgium, with 9.7% of world imports. Countries that did not report 2025 data are estimated from partner records, which can understate them.

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).
