About HS Code 292122

This HS code specifically covers hexamethylenediamine (HMDA) and its salts, an acyclic polyamine with six carbon atoms between its two amine groups. HMDA is a critical monomer, predominantly traded by polymer manufacturers, especially those involved in nylon production, and specialty chemical producers. Its most significant application is as a key building block for Nylon 6,6, a widely used synthetic polymer known for its strength and durability in textiles, plastics, and engineering applications. HMDA is also utilized in the production of coatings, adhesives, and cross-linking agents. International trade in HMDA is characterized by large-volume transactions, driven by the global demand for nylon and other HMDA-derived products, with a strong focus on consistent quality and supply chain reliability.

Products Under This Code

Hexamethylenediamine, Hexamethylenediamine dihydrochloride, N,N'-Diacetylhexamethylenediamine

Real World Examples

Invista (HMDA for Nylon 6,6), Ascend Performance Materials (HMDA for Nylon 6,6), BASF (HMDA production)

Common Misclassification

This code is very specific; misclassification might occur with other polyamines under 292129 if the chemical is not hexamethylenediamine, or with 292121 (ethylenediamine) if the carbon chain length is not correctly identified.

Products Classified Under 2921.22

Industry

This code belongs to the Chemicals industry.

Trade Overview

Top importing and exporting countries include those with large nylon manufacturing industries, such as the USA, China, Germany, and Japan.
