HS Code 2921.11 – Amine-function compounds; acyclic monoamines and their derivatives, methylamine, di- or trimethylamine and their salts

HS code 2921.11 is the 6-digit subheading for amine-function compounds, acyclic monoamines and their derivatives, methylamine, di- or trimethylamine and their salts. It is used for methylamine, dimethylamine, trimethylamine, methylamine hydrochloride and dimethylamine hydrochloride.

What HS 2921.11 covers

This HS code covers acyclic monoamines and their derivatives, specifically focusing on methylamine, di- or trimethylamine, and their salts. These are fundamental organic building blocks, characterized by a single amine functional group in an open-chain structure. They are extensively traded by chemical manufacturers, pharmaceutical companies, agrochemical producers, and dye industries. These amines serve as crucial intermediates in the synthesis of a vast array of products, including pharmaceuticals, pesticides, solvents, and surfactants. Due to their volatility, often pungent odor, and sometimes corrosive or flammable properties, their international trade requires stringent handling, storage, and transportation protocols, along with strict adherence to chemical safety and environmental regulations.

Covers
  • Methylamine
  • Dimethylamine
  • Trimethylamine
  • Methylamine hydrochloride
  • Dimethylamine hydrochloride
  • Trimethylamine hydrochloride
Examples
  • BASF (methylamines)

Codes often confused with 2921.11

Common mistake. This code can be confused with other acyclic monoamines under 292119 if the specific amine is not methyl-, di-, or trimethylamine, or with 292121 (polyamines) if the compound has more than one amine group.

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).
