HS Code for Ethylenediamine

2921.21 Amine-function compounds; acyclic polyamines and their derivatives, ethylenediamine and its salts
Chemicals
View full HS code details

Ethylenediamine is classified under HS code 2921.21 because it is an acyclic polyamine. Chapter 29 of the Harmonized System covers organic chemicals, and heading 2921 is dedicated to amine-function compounds. Within this heading, the sub-classification 2921.21 specifically identifies ethylenediamine and its salts. This classification is determined by the chemical's molecular structure, which consists of two amine groups attached to an ethane backbone (C2H8N2). As a primary aliphatic diamine, it serves as a critical intermediate in the production of chelating agents like EDTA, surfactants, and synthetic resins. The Harmonized System requires that pure organic compounds be classified based on their specific chemical identity, and 2921.21 provides a dedicated entry for this substance, ensuring uniform international trade documentation and duty application.

Products Included

Common Misclassification

Ethylenediamine is frequently confused with other polyamines. A common error is classifying it under HS code 2921.22, which is reserved for hexamethylenediamine and its salts. While both are acyclic polyamines, the carbon chain length differs significantly. Another common misclassification occurs with HS code 2921.29, which is a residual category for other acyclic polyamines and their derivatives. If the product is a derivative rather than a simple salt, such as diethylenetriamine, it must be moved to 2921.29. Additionally, if ethylenediamine is prepared as a stabilizer for other chemicals, it might be misclassified under Chapter 38.
