About HS Code 292129
This 'other' HS code covers acyclic polyamines and their derivatives, and salts thereof, not specifically listed in subheadings 292121 or 292122. This category encompasses a diverse range of polyamines with multiple amine functional groups in an open-chain structure, excluding ethylenediamine and hexamethylenediamine. Importers and exporters typically include specialty chemical companies, polymer research and development firms, and manufacturers of advanced materials. These polyamines are utilized in specialized polymer synthesis, as epoxy curing agents, cross-linking agents, and in the production of various high-performance materials. Trade in these 'other' polyamines often involves custom orders and smaller volumes of high-value chemicals, where precise chemical identification, purity, and adherence to specific technical requirements are crucial.
Products Under This Code
Diethylenetriamine, Triethylenetetramine, Tetraethylenepentamine, Spermidine, Spermine, Propylenediamine, Butylenediamine
Real World Examples
Dow Chemical (various polyamines), Huntsman Corporation (epoxy curing agents), Taminco (now Eastman Chemical, specialty polyamines)
Common Misclassification
As a residual category, misclassification often occurs when a specific polyamine should have been classified under 292121 or 292122, or if it is mistakenly identified as a monoamine (29211x series).
Industry
This code belongs to the Chemicals industry.
Trade Overview
Global trade is active in countries with advanced chemical industries and specialized manufacturing, including China, the USA, Germany, and Japan.
