HS Code 2921.12 – Amine-function compounds; acyclic monoamines and their derivatives, and salts thereof, 2-(N,N-Dimethylamino)ethylchloride hydrochloride
HS code 2921.12 is the 6-digit subheading for amine-function compounds, acyclic monoamines and their derivatives, and salts thereof, 2-(N,N-Dimethylamino)ethylchloride hydrochloride. It is used for 2-(N,N-Dimethylamino)ethylchloride hydrochloride and DMAC-HCl.
What HS 2921.12 covers
This specific HS code identifies 2-(N,N-Dimethylamino)ethylchloride hydrochloride, an acyclic monoamine derivative and its salt. This compound is a specialized chemical intermediate, crucial for the synthesis of more complex organic molecules. Its primary importers and exporters are fine chemical manufacturers, pharmaceutical companies, and research institutions that require precise building blocks for their synthetic processes. It is frequently used as a precursor in the production of active pharmaceutical ingredients (APIs), dyes, and other specialty chemicals. The trade in such highly specific compounds demands meticulous quality control, high purity standards, and strict compliance with chemical regulations, given its role in sensitive applications like drug manufacturing.

Codes often confused with 2921.12
Common mistake. This code is very specific; misclassification might occur with 292119 (other acyclic monoamines) if the exact chemical name is not recognized, or with 292113 or 292114 if the diethyl or diisopropyl analogues are mistakenly identified.
Top exporters and importers of HS code 292112, 2025
In 2025, the largest exporter of HS code 292112 in UN Comtrade data was India, with 41% of world exports; the largest importer in UN Comtrade data was Sweden, with 17% 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).
