HS Code 2825.10 – Hydrazine and hydroxylamine and their inorganic salts
HS code 2825.10 is the 6-digit subheading for hydrazine and hydroxylamine and their inorganic salts. It is used for hydrazine hydrate, hydrazine sulfate, hydrazine dihydrochloride, hydroxylamine hydrochloride and hydroxylamine sulfate.
What HS 2825.10 covers
This HS code covers hydrazine, hydroxylamine, and their various inorganic salts, which are highly reactive and versatile nitrogen-containing compounds. These materials are critical intermediates and reagents in a wide range of industrial processes. In international trade, they are primarily exchanged between chemical manufacturers, pharmaceutical companies, agricultural chemical producers, and specialized polymer industries. Importers include countries with advanced chemical synthesis capabilities, particularly those involved in producing pharmaceuticals, agrochemicals, and specialty polymers. Exporters are typically nations with sophisticated chemical production facilities capable of safely manufacturing and handling these reactive substances. Key things to know involve their powerful reducing properties, making them valuable in organic synthesis, as oxygen scavengers in boilers, and as blowing agents for plastics. Due to their reactivity and potential hazards, strict safety protocols and specialized packaging are paramount in their international transport and storage, significantly influencing trade logistics and costs. Purity and specific salt form are crucial trade specifications.

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).
