2921.29.00.30 - Diethylenetriamine

This classification, 2921.29.00.30, specifically covers Diethylenetriamine (DETA). DETA is an organic chemical compound belonging to the acyclic polyamine group, characterized by its structure containing two ethyl groups and three amine functionalities. It is a linear molecule with the chemical formula C4H13N3. As a versatile chemical intermediate, DETA finds applications in various industrial processes, including the production of epoxy curing agents, chelating agents, and as a raw material in the synthesis of other complex organic compounds.

This particular subheading is distinct from its siblings due to the specific chemical structure and identity of the polyamine. While 2921.29.00.10 covers Tetraethylene pentamine and 2921.29.00.20 covers Triethylenetetramine, both of which are longer chain polyamines with more amine groups, this subheading focuses exclusively on DETA, which has a shorter chain and fewer amine groups. The "Other" subheading, 2921.29.00.55, is reserved for any other acyclic polyamines and their derivatives or salts not specifically enumerated within the preceding subheadings.

As a leaf node, this classification does not have further subcategories. Therefore, the primary classification criteria for goods falling under 2921.29.00.30 will rely on the precise chemical identification and purity of Diethylenetriamine. Importers and exporters must ensure that the goods accurately match the chemical properties and name associated with Diethylenetriamine to be correctly classified under this subheading.
