HS code for Diethanolamine: 2922.12
Amino-alcohols, other than those containing more than one kind of oxygen function, their ethers and esters, salts thereof, diethanolamine and its salts.
Classification of diethanolamine under HS 2922.12
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.

Codes often confused with 2922.12
Common mistake. 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.
Top exporters and importers of HS 292212 (the code used for diethanolamine), 2025
In 2025, the largest exporter of HS 292212 (the code used for diethanolamine) in UN Comtrade data was Saudi Arabia, with 41% of world exports; the largest importer in UN Comtrade data was the United States, with 45% 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).

How do I classify Diethanolamine for customs?
Diethanolamine is classified under HS code 292212 — Amino-alcohols, other than those containing more than one kind of oxygen function; their ethers and esters; salts thereof, diethanolamine and its salts. This is a 6-digit subheading level code.
Is diethanolamine regulated under international conventions?
Yes, diethanolamine is often monitored under the Chemical Weapons Convention (CWC) as a Schedule 3 substance, which may require additional import/export declarations.
Which countries are the top exporters of diethanolamine (HS 292212)?
In 2025, the top exporters of HS 292212 (the code used for diethanolamine) in UN Comtrade data were Saudi Arabia ($92M, 41% of world exports), Belgium ($70M) and Sweden ($13M). World exports came to about $224M, adding countries' reported figures and partner-based estimates for those that did not report (UN Comtrade data). Countries that did not report 2025 data are estimated from partner records, which can understate them.
