HS Code 2921.19 – Amine-function compounds; acyclic monoamines and their derivatives, and salts thereof, n.e.c. in item no. 2921.1

HS code 2921.19 is the 6-digit subheading for amine-function compounds, acyclic monoamines and their derivatives, and salts thereof, n.e.c. in item no. 2921.1. It is used for butylamine, hexylamine, octylamine, cyclohexylamine and isopropylamine.

What HS 2921.19 covers

This 'other' HS code covers acyclic monoamines and their derivatives, and salts thereof, not specifically enumerated in subheadings 292111 through 292114. This broad category includes a wide range of less common or more specialized acyclic monoamines, each with unique properties and applications. Importers and exporters typically include specialty chemical manufacturers, research institutions, and niche pharmaceutical companies that require specific amine structures for their unique synthetic pathways. These compounds are often used in custom synthesis, as intermediates for advanced materials, or in specialized research applications. Trade in these 'other' monoamines is characterized by diverse demand, often involving smaller quantities of high-value chemicals, where precise chemical identification and regulatory compliance are paramount.

Codes often confused with 2921.19

Common mistake. This code is a residual category, so misclassification often occurs when a specific acyclic monoamine should have been classified under 292111-292114, or if it is mistakenly identified as a polyamine (29212x series).

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).
