HS Code 2928.00 – Organic derivatives of hydrazine or of hydroxylamine
HS code 2928.00 is the 6-digit subheading for organic derivatives of hydrazine or of hydroxylamine. It is used for phenylhydrazine, acetone hydrazone, semicarbazide, hydroxylamine hydrochloride and N,N-Dimethylhydrazine.
What HS 2928.00 covers
This category covers organic compounds derived from hydrazine (N2H4) or hydroxylamine (NH2OH), characterized by the presence of nitrogen-nitrogen or nitrogen-oxygen bonds within their organic structure. These derivatives are vital intermediates in the synthesis of a wide range of specialty chemicals, including pharmaceuticals, agrochemicals, polymers, and rubber processing chemicals. They are also used as reducing agents, antioxidants, and in various analytical applications. Major importers are typically countries with advanced chemical and pharmaceutical manufacturing capabilities, such as the United States, Germany, China, and Japan, where these derivatives are transformed into higher-value end products. Exporters often include large chemical companies in China, Germany, and the US. Key considerations in trading these compounds include their specific chemical structure, purity, and stability, as these factors are critical for their performance in complex synthesis reactions. Safety and handling protocols are also paramount due to the reactive nature of some derivatives.

Common mistake. This code might be confused with other nitrogen-function compounds in Chapter 29, particularly 292990, if the specific hydrazine or hydroxylamine derivative structure is not clearly identified.
Top exporters and importers of HS code 292800, 2025
In 2025, the largest exporter of HS code 292800 in UN Comtrade data was Switzerland, with 38% of world exports; the largest importer in UN Comtrade data was Brazil, with 20% 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).
