HS Code 2922.17 – Amino-alcohols, other than those containing more than one kind of oxygen function; their ethers and esters; salts thereof, Methyldiethanolamine and ethyldiethanolamine
HS code 2922.17 is the 6-digit subheading for amino-alcohols, other than those containing more than one kind of oxygen function, their ethers and esters, salts thereof, Methyldiethanolamine and ethyldiethanolamine. It is used for methyldiethanolamine, MDEA, N-Methyldiethanolamine, ethyldiethanolamine and EDEA.
What HS 2922.17 covers
Methyldiethanolamine (MDEA) and Ethyldiethanolamine (EDEA) are crucial amino-alcohols primarily utilized in gas treatment processes, particularly for the selective removal of hydrogen sulfide (H2S) and carbon dioxide (CO2) from natural gas, refinery gases, and synthesis gas streams. MDEA is especially valued for its high selectivity towards H2S over CO2, making it a preferred solvent in many gas sweetening units within the oil and gas industry. EDEA shares similar applications but is less common. These compounds are essential for ensuring the purity of natural gas and preventing corrosion in pipelines and equipment. Importers and exporters are typically chemical manufacturers, distributors, and companies serving the petrochemical, oil and gas, and chemical processing industries. Key things to know include their role in enhancing energy efficiency, the importance of purity for optimal performance in gas sweetening, and the need for careful handling due to their corrosive nature.

Codes often confused with 2922.17
Common mistake. This code could be confused with other amino-alcohols used in gas sweetening, such as monoethanolamine (292211) or diethanolamine (292212), but 292217 specifically covers the N-methyl and N-ethyl substituted diethanolamines.
Top exporters and importers of HS code 292217, 2025
In 2025, the largest exporter of HS code 292217 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).

What are common misclassifications for HS code 292217?
This code could be confused with other amino-alcohols used in gas sweetening, such as monoethanolamine (292211) or diethanolamine (292212), but 292217 specifically covers the N-methyl and N-ethyl substituted diethanolamines.
Which countries are the top exporters of goods under HS code 292217?
In 2025, the top exporters of HS code 292217 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.
