HS code for Hydroxylamine: 2825.10
Hydrazine and hydroxylamine and their inorganic salts.
Classification of hydroxylamine under HS 2825.10
Hydroxylamine and its inorganic salts are classified under HS code 2825.10. This classification is situated within Chapter 28, which covers inorganic chemicals, precious metals, and rare-earth metals. Specifically, heading 2825 is designated for hydrazine and hydroxylamine and their inorganic salts, as well as other inorganic bases and metal oxides, hydroxides, and peroxides. The classification is straightforward under GRI 1, as the heading text explicitly names the substance. Hydroxylamine (NH2OH) is a reactive compound often used as a reducing agent or in the synthesis of oximes. It is important to distinguish between the pure inorganic form and its salts, such as hydroxylammonium sulfate or chloride, which are also included here. The classification is based on the chemical composition of the substance as an inorganic base. In the Harmonized System, the distinction between inorganic and organic chemicals is vital; since hydroxylamine is an inorganic derivative of ammonia where one hydrogen atom is replaced by a hydroxyl group, it remains in Chapter 28. This code is essential for customs to monitor the trade of chemicals that may have industrial, pharmaceutical, or laboratory applications, ensuring that safety and regulatory standards are met during international transit.

Codes often confused with 2825.10
Common mistake. Hydroxylamine is often confused with its organic derivatives, which are classified under heading 2928. While 2825.10 covers the inorganic salts, any organic substitution on the nitrogen or oxygen atom moves the product to Chapter 29. Additionally, some importers mistakenly use 2833.29 for hydroxylammonium sulfate, but 2825.10 is more specific and takes precedence according to GRI 3(a).
Top exporters and importers of HS 282510 (the code used for hydroxylamine), 2025
In 2025, the largest exporter of HS 282510 (the code used for hydroxylamine) in UN Comtrade data was Germany, with 45% of world exports; the largest importer in UN Comtrade data was India, with 22% of world imports. Countries that did not report 2025 data are estimated from partner records, which can understate them.
Figures cover everything classified under HS 282510, not only hydroxylamine.

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).
