Product classification

HS code for Methylamine: 2921.11

Amine-function compounds, acyclic monoamines and their derivatives, methylamine, di- or trimethylamine and their salts.

Classification of methylamine under HS 2921.11

Methylamine, along with its derivatives dimethylamine and trimethylamine, is classified under HS code 2921.11. This classification is found in Chapter 29, which covers organic chemicals, and heading 2921, which is dedicated to amine-function compounds. Subheading 2921.11 specifically covers acyclic monoamines including methylamine, di- or trimethylamine, and their salts. These chemicals are basic organic compounds where one or more hydrogen atoms in ammonia are replaced by methyl groups. The classification includes these substances in their anhydrous form or in aqueous solutions, as well as their various salts, such as methylamine hydrochloride. These compounds are essential building blocks in the synthesis of pharmaceuticals, pesticides, and surfactants.

Codes often confused with 2921.11

Common mistake. Methylamine is sometimes misclassified under HS code 2921.19, which is the residual category for other acyclic monoamines. However, because methylamine and its methyl-derivatives are explicitly named in 2921.11, that code must be used. It can also be confused with amino-alcohols like ethanolamine, which are classified under heading 2922.

Top exporters and importers of HS 292111 (the code used for methylamine), 2025

In 2025, the largest exporter of HS 292111 (the code used for methylamine) in UN Comtrade data was Belgium, with 26% of world exports; the largest importer in UN Comtrade data was India, with 16% 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).

Questions about methylamine

What is the HS code for Methylamine?

The HS code for Methylamine is 292111 (Amine-function compounds; acyclic monoamines and their derivatives, methylamine, di- or trimethylamine and their salts). The HS code for methylamine, dimethylamine, and trimethylamine, including their salts, is 2921.11.

How do I classify Methylamine for customs?

Methylamine is classified under HS code 292111 — Amine-function compounds; acyclic monoamines and their derivatives, methylamine, di- or trimethylamine and their salts. This is a 6-digit subheading level code.

Are aqueous solutions of methylamine classified differently?

No, aqueous solutions of these amines are classified under the same HS code (2921.11) as the anhydrous forms, provided they are not mixed with other substances that change their character.

Which countries are the top exporters of methylamine (HS 292111)?

In 2025, the top exporters of HS 292111 (the code used for methylamine) in UN Comtrade data were Belgium ($66M, 26% of world exports), India ($62M) and South Korea ($24M). World exports came to about $249M, adding countries' reported figures and partner-based estimates for those that did not report (UN Comtrade data).
