HS Code for Diisopropylaminoethyl chloride hydrochloride

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.

Products Included

• 2-(Diisopropylamino)ethyl chloride hydrochloride
• N,N-Diisopropyl-2-chloroethylamine hydrochloride
• Diisopropylaminoethyl chloride HCl salt
• C8H19Cl2N (Chemical formula variant)

Common Misclassification

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.
