Product classification
HS code for Dimethylaminoethyl chloride hydrochloride: 2921.12
Amine-function compounds, acyclic monoamines and their derivatives, and salts thereof, 2-(N,N-Dimethylamino)ethylchloride hydrochloride.
Classification of dimethylaminoethyl chloride hydrochloride under HS 2921.12
Dimethylaminoethyl chloride hydrochloride is classified under HS code 2921.12. This classification falls under heading 2921, which covers amine-function compounds. Specifically, it is categorized under the subheading for acyclic monoamines and their derivatives. The compound 2-(N,N-Dimethylamino)ethylchloride hydrochloride is a salt of a derivative of an acyclic monoamine. According to the legal notes of Chapter 29, specifically Note 5, salts of organic compounds are classified in the same subheading as the base from which they are derived. Since the base (dimethylaminoethyl chloride) is an acyclic monoamine derivative and the subheading 2921.12 specifically identifies this compound by name, it is the only correct classification under GRI 1 and 6.

Codes often confused with 2921.12
Common mistake. This product is often confused with HS code 2921.14, which is the diisopropylaminoethyl chloride hydrochloride variant. The difference lies in the alkyl groups (dimethyl vs. diisopropyl). It is also frequently misclassified under 2921.19 (other acyclic monoamines). Because 2921.12 is a specific 6-digit code created for international monitoring (often related to the Chemical Weapons Convention), it must be used instead of the general "other" category. Importers must ensure the chemical name matches the dimethyl structure to avoid using the codes for methylamine (2921.11) or ethylamine (2921.19).

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).
