Importers of Methyldiethanolamine (MDEA) and Ethyldiethanolamine (EDEA) paid $19K in duties in August 2026, an average duty rate of 10.00% — duty actually collected as a share of the imports that cleared customs, not the published tariff schedule. Methyldiethanolamine (MDEA) and Ethyldiethanolamine (EDEA) imports of $188K in August 2026 ran 64% below the year-to-date monthly average of $527K.
Last updated: August 2026 dataMethyldiethanolamine (MDEA) is a selectively absorbing solvent widely used in natural gas and refinery acid-gas treating systems to remove hydrogen sulfide and carbon dioxide, making it a critical process chemical for the energy sector. Belgium and Germany are the primary US suppliers, with India and Canada also contributing. Both MDEA and its ethyl analog are covered under the single line 2922170000; importers should specify the exact compound on the commercial invoice, as MDEA and EDEA have distinct CAS numbers and may have different downstream regulatory profiles.

MDEA's selectivity for H₂S over CO₂ and its lower regeneration energy requirements make it the preferred solvent in many modern gas-treating units. From a classification standpoint, however, MDEA and MEA/DEA are each classified under their own distinct HS6 headings (292217 vs. 292211/292212), so the technical preference does not affect the tariff line — the chemical identity of the compound governs classification.
Goods originating in Canada that meet USMCA rules of origin are eligible for preferential tariff treatment under the agreement. For MDEA imported from Canada, importers should obtain a USMCA certificate or certification of origin from the Canadian supplier and retain it for five years to support any preference claim at entry.
