2921.19.61.20 - Bis(2-chloroethyl)ethylamine)

This HTS subheading, 2921.19.61.20, specifically classifies Bis(2-chloroethyl)ethylamine. This compound is a type of acyclic secondary amine characterized by the presence of two chloroethyl groups attached to the nitrogen atom. Its classification within Chapter 29, "Organic Chemicals," and specifically under headings related to amines, reflects its chemical structure and function.

The distinction between this subheading and its siblings lies in the specific chemical structure and the nature of the substituents on the amine nitrogen. While other subheadings in the 2921.19.61 series cover different alkylated or substituted chloroethylamines, such as N,N-dialkyl variants, chlormethine, or trichlormethine, this particular code is reserved for the compound where the nitrogen atom is substituted with precisely two 2-chloroethyl groups and no other alkyl or amino substituents. This precise structural definition is crucial for accurate customs classification.

As this is a leaf node within the HTS, there are no further subcategories for Bis(2-chloroethyl)ethylamine. Therefore, classification at this level is definitive based on the chemical identity of the imported or exported substance. The focus for classification professionals will be on confirming the chemical composition to ensure it precisely matches the definition of Bis(2-chloroethyl)ethylamine.
