Products classified under HTS 2921.29.00.20
Triethylenetetramine (TETA)
Triethylenetetramine is an acyclic polyamine classified under HTS 2921.29.0020 as a chemically defined organic compound with multiple amine groups. It is primarily used as a curing agent in epoxy resin formulations for coatings, adhesives, and composites.
Technical Grade Triethylenetetramine 98% Pure
Technical grade TETA at 98% minimum purity, specifically classified under HTS 2921.29.0020 as the designated acyclic polyamine. Used in industrial applications including polyurethane production and metal chelation.
Diethylenetriamine (DETA) Impurity-Free TETA
High-purity triethylenetetramine specifically manufactured to minimize DETA impurities, classified under HTS 2921.29.0020. Critical for high-performance epoxy systems in aerospace composites.
Stabilized Triethylenetetramine for Export
TETA with added stabilizer per Chapter Note 2(f), maintaining classification under HTS 2921.29.0020. Stabilizer prevents oxidation during long-distance marine transport.
TETA Dihydrochloride Salt
Triethylenetetramine dihydrochloride salt, classified under HTS 2921.29.0020 per Chapter Note 5(C)(1) with the parent polyamine. Used in pharmaceutical chelation therapy and water treatment.
