Product classification
HS code for Hydrazine: 2825.10
Hydrazine and hydroxylamine and their inorganic salts.
Classification of hydrazine under HS 2825.10
Hydrazine is classified under HS code 282510, which specifically covers hydrazine and hydroxylamine along with their inorganic salts. This classification is determined by the General Rules for the Interpretation of the Harmonized System (GRI), specifically GRI 1, which dictates that classification is determined by the terms of the headings and any relative section or chapter notes. As an inorganic base, hydrazine falls within Chapter 28, which encompasses inorganic chemicals, precious metals, and rare-earth metals. The specific subheading 282510 is designated for hydrazine and its derivatives because they are chemically defined inorganic compounds. The classification remains consistent regardless of whether the hydrazine is in anhydrous form or as an aqueous solution (hydrazine hydrate), provided no other substances have been added that would change its essential character as a basic chemical building block.

Codes often confused with 2825.10
Common mistake. Hydrazine is frequently misclassified under HS code 282590, which is a residual category for other inorganic bases and metal oxides. However, because 282510 provides a specific named entry for hydrazine, it must take precedence. Another common error involves organic derivatives of hydrazine, such as methylhydrazine, which should be classified under HS code 292800 (Organic derivatives of hydrazine or of hydroxylamine) rather than the inorganic heading. Importers must distinguish between the pure inorganic base and its organic substituted counterparts to avoid customs delays.
Top exporters and importers of HS 282510 (the code used for hydrazine), 2025
In 2025, the largest exporter of HS 282510 (the code used for hydrazine) 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 hydrazine.

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).

Questions about hydrazine
What is the HS code for Hydrazine?
The HS code for Hydrazine is 282510 (Hydrazine and hydroxylamine and their inorganic salts). The primary HS code for hydrazine, including its hydrate and inorganic salts, is 282510.
How do I classify Hydrazine for customs?
Hydrazine is classified under HS code 282510 — Hydrazine and hydroxylamine and their inorganic salts. This is a 6-digit subheading level code.
Is hydrazine hydrate classified differently than anhydrous hydrazine?
No, both anhydrous hydrazine and hydrazine hydrate are classified under HS code 282510, as the hydrate is considered an aqueous solution of the inorganic base.
Which countries are the top exporters of hydrazine (HS 282510)?
In 2025, the top exporters of HS 282510 (the code used for hydrazine) in UN Comtrade data were Germany ($117M, 45% of world exports), France ($31M) and China ($30M). World exports came to about $258M, adding countries' reported figures and partner-based estimates for those that did not report (UN Comtrade data). Countries that did not report 2025 data are estimated from partner records, which can understate them.
Which countries are the top importers of hydrazine (HS 282510)?
In 2025, the top importers of HS 282510 (the code used for hydrazine) in UN Comtrade data were India ($61M, 22% of world imports), the United States ($32M) and China ($28M). World imports came to about $283M, adding countries' reported figures and partner-based estimates for those that did not report (UN Comtrade data). Countries that did not report 2025 data are estimated from partner records, which can understate them.
Is the HS code for Hydrazine the same in all countries?
The base HS code 282510 for Hydrazine is internationally standardized for the first 6 digits across 200+ countries. Individual countries may add additional digits for national tariff lines and specific classifications.
What is the NCM code for hydrazine in Brazil?
Brazil splits HS 282510 into 2 NCM codes, so the right one for hydrazine depends on the product's details: 2825.10.10 (Hydrazine and its inorganic salts), 2825.10.20 (Hydroxylamine and its inorganic salts).
