HS Code for Hydroxylamine

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.

Products Included

• Pure hydroxylamine in aqueous solution
• Hydroxylammonium chloride (Hydroxylamine hydrochloride)
• Hydroxylammonium sulfate
• Hydroxylammonium nitrate
• Hydroxylammonium phosphate

Common Misclassification

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).
