HS code · 6-digit subheading

HS Code 2922.39 – Amino-aldehydes, amino-ketones and amino-quinones; other than those containing more than one kind of oxygen function; salts thereof, excluding amfepramone (INN), methadone (INN), and normethadone (INN) and salts thereof

HS code 2922.39 is the 6-digit subheading for amino-aldehydes, amino-ketones and amino-quinones, other than those containing more than one kind of oxygen function, salts thereof, excluding amfepramone (INN), methadone (INN), and normethadone (INN) and salts thereof. It is used for 4-Aminobenzophenone, 2-Aminoacetophenone, 3-Aminopropiophenone, 4-Amino-2-methylbenzaldehyde and 2-Amino-1-indanone.

What HS 2922.39 covers

This HS code encompasses a broad category of organic compounds characterized by both an amino group and an aldehyde, ketone, or quinone group, provided they contain only one type of oxygen function. The critical distinction for this code is the explicit exclusion of specific controlled substances like amfepramone (INN), methadone (INN), and normethadone (INN), which fall under stricter regulatory regimes due to their pharmaceutical applications as controlled drugs. In international trade, these chemicals serve as versatile intermediates in the synthesis of a wide array of products, including pharmaceuticals, dyes, and agrochemicals. Importers are typically chemical manufacturers, research laboratories, and companies involved in custom synthesis, seeking these building blocks for their production processes. Exporters are often countries with robust chemical industries, particularly those specializing in fine chemicals and intermediates. Key considerations for trade include purity specifications, handling precautions due to potential reactivity, and ensuring compliance with international chemical regulations, especially regarding the excluded substances.

Codes often confused with 2922.39

Common mistake. This code is often confused with 292231, which covers the general class of amino-aldehydes/ketones/quinones without the specific exclusions. Misclassification can occur if the excluded substances are not properly identified or if a compound's specific oxygen function is ambiguous.

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).
