HS code for Methyldiethanolamine: 2922.17
Amino-alcohols, other than those containing more than one kind of oxygen function, their ethers and esters, salts thereof, Methyldiethanolamine and ethyldiethanolamine.
Classification of methyldiethanolamine under HS 2922.17
Methyldiethanolamine (MDEA) is classified under HS code 2922.17. This classification falls under Chapter 29 (Organic Chemicals) and heading 2922, which covers oxygen-function amino-compounds. Specifically, subheading 2922.17 is designated for methyldiethanolamine and ethyldiethanolamine. MDEA is an amino-alcohol, meaning it contains both an amine group and alcohol groups (hydroxyls) within its molecular structure. It is widely used in the oil and gas industry for "gas sweetening," a process that removes acidic gases like hydrogen sulfide (H2S) and carbon dioxide (CO2) from gas streams. The classification covers the pure chemical and its salts. Because MDEA is also a precursor chemical listed under the Chemical Weapons Convention (Schedule 3), its classification is vital for international regulatory compliance.

Codes often confused with 2922.17
Common mistake. MDEA is often misclassified under HS code 2922.11 (monoethanolamine), 2922.12 (diethanolamine), or 2922.15 (triethanolamine). While these are all ethanolamines, MDEA is a tertiary amine with a methyl group, requiring the specific code 2922.17. It may also be incorrectly placed in 3824.99 if it is part of a proprietary formulated gas-treating solvent.
Top exporters and importers of HS 292217 (the code used for methyldiethanolamine), 2025
In 2025, the largest exporter of HS 292217 (the code used for methyldiethanolamine) in UN Comtrade data was the United States, with 33% of world exports; the largest importer in UN Comtrade data was Saudi Arabia, with 17% 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 marked * did not, so their figures add up what other countries recorded trading with them, and their exports are valued at buyers' CIF prices. 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).

Questions about methyldiethanolamine
What is the HS code for Methyldiethanolamine?
The HS code for Methyldiethanolamine is 292217 (Amino-alcohols, other than those containing more than one kind of oxygen function; their ethers and esters; salts thereof, Methyldiethanolamine and ethyldiethanolamine). The HS code for methyldiethanolamine (MDEA) is 2922.17.
How do I classify Methyldiethanolamine for customs?
Methyldiethanolamine is classified under HS code 292217 — Amino-alcohols, other than those containing more than one kind of oxygen function; their ethers and esters; salts thereof, Methyldiethanolamine and ethyldiethanolamine. This is a 6-digit subheading level code.
Why is MDEA subject to additional trade controls?
MDEA is a precursor chemical that can be used in the production of chemical warfare agents (such as nitrogen mustards), and therefore its trade is monitored under the Chemical Weapons Convention.
Which countries are the top exporters of methyldiethanolamine (HS 292217)?
In 2025, the top exporters of HS 292217 (the code used for methyldiethanolamine) in UN Comtrade data were the United States ($34M, 33% of world exports), India ($29M) and Belgium ($21M). World exports came to about $104M, 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.
Which countries are the top importers of methyldiethanolamine (HS 292217)?
In 2025, the top importers of HS 292217 (the code used for methyldiethanolamine) in UN Comtrade data were Saudi Arabia ($22M, 17% of world imports), the United Arab Emirates (about $8.1M) and Indonesia ($8.1M). World imports came to about $131M, 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.
Is the HS code for Methyldiethanolamine the same in all countries?
