HS Code for Methyldiethanolamine
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.
Products Included

Common Misclassification
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.
FAQ
What is the HS code for methyldiethanolamine?
The HS code for methyldiethanolamine (MDEA) is 2922.17.
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.
