2921.30.05.00 - 1,3-Bis(aminoethyl)cyclohexane

This classification covers specific cyclic diamines derived from cyclohexane and containing aminoethyl groups. The defining characteristic is the presence of two aminoethyl substituents attached to a cyclohexane ring, resulting in the chemical compound 1,3-Bis(aminoethyl)cyclohexane. These compounds are used in various industrial applications, including as monomers for polymers, curing agents for epoxy resins, and as intermediates in the synthesis of other specialty chemicals.

This category is distinct from other amine classifications by its specific cyclic structure and the presence of both the cyclohexane ring and the two aminoethyl functional groups. While other sections may cover aliphatic amines or aromatic amines, this node precisely identifies diamines based on a saturated cyclic hydrocarbon backbone. The "Derived in whole or in part from any aromatic compound" parent context highlights that while the final product is cyclanic, its synthetic pathway might involve aromatic precursors.

As this is a leaf node within the HTS, there are no further subcategories. Classification under HTS code 2921.30.05.00 is determined by the precise chemical identity of 1,3-Bis(aminoethyl)cyclohexane. Importers and exporters must ensure their goods strictly conform to this specific chemical structure to fall under this tariff code. Any variations in the number or type of functional groups, or significant structural differences in the cyclic component, would necessitate classification under a different HTS code.
