HS code for Diisopropylaminoethyl chloride hydrochloride: 2921.14
Amine-function compounds, acyclic monoamines and their derivatives, and salts thereof, 2-(N,N-Diisopropylamino)ethylchloride hydrochloride.
Classification of diisopropylaminoethyl chloride hydrochloride under HS 2921.14
Diisopropylaminoethyl chloride hydrochloride is classified under HS code 2921.14. This classification is determined by the General Rules of Interpretation (GRI) 1 and 6, which prioritize the specific nomenclature of the Harmonized System. According to Chapter 29 of the Harmonized Tariff Schedule, which covers organic chemicals, heading 2921 is reserved for amine-function compounds. Within this heading, acyclic monoamines and their derivatives are categorized. Diisopropylaminoethyl chloride hydrochloride is a specific derivative of an acyclic monoamine, specifically 2-(N,N-Diisopropylamino)ethylchloride in its hydrochloride salt form. Note 5 to Chapter 29 specifies that salts of organic compounds are generally classified in the same subheading as the corresponding acid or base, provided they are not more specifically covered elsewhere. Since 2921.14 explicitly names this compound, it takes precedence over more general subheadings.

Codes often confused with 2921.14
Common mistake. This substance is frequently misclassified under HS code 2921.19, which serves as a residual category for "other" acyclic monoamines. However, because 2921.14 is a specific 6-digit subheading created to monitor chemicals related to the Chemical Weapons Convention, it must be used instead of the general category. It is also sometimes confused with 2921.11 (methylamine and its salts) or 2921.12 (2-(N,N-Dimethylamino)ethylchloride hydrochloride) due to structural similarities in the alkyl chains. Accurate identification of the diisopropyl group is essential to distinguish it from the dimethyl variant.
Top exporters and importers of HS 292114 (the code used for diisopropylaminoethyl chloride hydrochloride), 2025
In 2025, the largest exporter of HS 292114 (the code used for diisopropylaminoethyl chloride hydrochloride) in UN Comtrade data was Belgium, with 73% of world exports; the largest importer in UN Comtrade data was Belgium, with 51% of world imports.

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).
