HS Code 2829.90 – Perchlorates; bromates and perbromates; iodates and periodates
HS code 2829.90 is the 6-digit subheading for perchlorates, bromates and perbromates, iodates and periodates. It is used for ammonium perchlorate, potassium perchlorate, sodium perchlorate, sodium bromate and potassium bromate.
What HS 2829.90 covers
This comprehensive HS code groups together perchlorates, bromates, perbromates, iodates, and periodates – a range of powerful oxidizing agents with highly specialized industrial applications. These chemicals are vital in areas such as rocket propellants (perchlorates), analytical chemistry, and certain pharmaceutical syntheses. Major importers include countries with advanced aerospace industries, sophisticated chemical research facilities, and specialized manufacturing sectors, such as the USA, Russia, and various European nations. Exporters are typically nations with sophisticated chemical production capabilities and stringent quality control, including the USA, China, and Germany. Key trade considerations involve extremely stringent safety regulations for handling and transporting these highly reactive and potentially explosive materials, ensuring ultra-high purity for sensitive applications, and compliance with international non-proliferation treaties for certain compounds. The market is driven by high-tech industrial and defense sector demands.

Codes often confused with 2829.90
Common mistake. This code is often confused with chlorates (282911, 282919) due to similar names, but perchlorates have an additional oxygen atom and distinct chemical properties.
Top exporters and importers of HS code 282990, 2025
In 2025, the largest exporter of HS code 282990 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).
