HS Code for Diethanolamine

Diethanolamine (DEA) is classified under HS code 2922.12. This substance is an organic chemical compound that serves as both a secondary amine and a dialcohol (a diol). According to the Harmonized System, Chapter 29 covers organic chemicals. Heading 2922 is designated for oxygen-function amino-compounds. Specifically, subheading 2922.12 is a specific entry for diethanolamine and its salts. The classification is determined by the chemical structure: the presence of an amino group and two hydroxyl groups on an acyclic chain. Because it contains only one type of oxygen function (alcohol), it is categorized within the 2922.1 series. If the molecule contained additional oxygen functions like carboxylic acids or aldehydes, it would be moved to a different subheading within 2922. The salts of diethanolamine, such as diethanolamine hydrochloride, are also included in this code per the heading description. This chemical is widely used in industrial processes, including gas scrubbing and the production of surfactants, but its classification remains strictly tied to its chemical identity under GRI 1. The compound must be a separate chemically defined compound to stay within Chapter 29; if it were part of a prepared mixture for a specific use, it might move to Chapter 34 or 38. However, technical grade diethanolamine, which may contain small amounts of other ethanolamines, is still typically classified here. The precision of the 2922.12 code reflects the importance of this chemical in global trade and regulatory monitoring.

Common Misclassification

Diethanolamine is frequently confused with Monoethanolamine (HS code 2922.11) and Triethanolamine (HS code 2922.13). These are closely related amino-alcohols but differ in the number of ethanol groups attached to the nitrogen atom. Misclassification can also occur with 2922.19, which is a residual category for other amino-alcohols not specifically named in the preceding subheadings.

FAQ

What is the HS code for Diethanolamine?
