Products classified under HTS 2921.21.00.00
Ethylenediamine
Ethylenediamine (EDA) is a colorless liquid organic compound with the formula H2NCH2CH2NH2, classified under HTS 2921.21.00.00 as a basic acyclic polyamine. It is a key industrial intermediate used in chelating agents, pharmaceuticals, and polymer production, meeting Chapter 29 requirements for separate chemically defined organic compounds.
Ethylenediamine Dihydrochloride
Ethylenediamine dihydrochloride (C2H8N2·2HCl) is the salt form of ethylenediamine, a white crystalline powder used in pharmaceutical synthesis and polymer curing. It falls under HTS 2921.21.00.00 per Chapter 29 note on salts of organic amine compounds classified with the parent base.
N-Ethylethylenediamine
N-Ethylethylenediamine is a derivative of ethylenediamine with one amine group mono-substituted by ethyl (H2NCH2CH2NHCH2CH3), remaining an acyclic polyamine. Classified under HTS 2921.21.00.00 as it retains the essential ethylenediamine structure with minimal derivatization.
Ethylenediamine Monohydrate
Ethylenediamine monohydrate contains EDA dissolved in water at standard transport concentration (30-70% EDA), classified under HTS 2921.21.00.00 per Chapter 29 note (d) for aqueous solutions of defined organic compounds.
Ethylenediamine Tetraacetic Acid (EDTA) Precursor Grade
High-purity ethylenediamine specifically graded for EDTA chelant synthesis, remains classified as the base compound under HTS 2921.21.00.00. Meets Chapter 29 criteria for chemically defined acyclic polyamines used as chemical intermediates.
