About HS Code 292151

This HS code covers specific aromatic polyamines: o-, m-, p-phenylenediamine, diaminotoluenes, and their derivatives, including their salts. These compounds are critical building blocks for a wide range of industrial products. Phenylenediamines are essential for hair colorants, aramid fibers (like Kevlar), and rubber chemicals, while diaminotoluenes are key precursors for toluene diisocyanate (TDI), a major component in polyurethane foams. Their distinct isomeric forms offer different properties and applications. Trade is significant, with major chemical producers supplying to industries like automotive, textiles, and cosmetics. Importers are typically manufacturers of polymers, dyes, and personal care products, seeking high-purity intermediates.

Products Under This Code

p-Phenylenediamine, m-Phenylenediamine, o-Phenylenediamine, Toluene-2,4-diamine, Toluene-2,6-diamine, N,N'-diphenyl-p-phenylenediamine, 4-chloro-o-phenylenediamine

Real World Examples

DuPont (Kevlar uses p-phenylenediamine), Covestro (TDI uses diaminotoluenes), L'Oréal (hair dyes use phenylenediamines), Lanxess (rubber chemicals), BASF (intermediates)

Common Misclassification

Can be confused with other aromatic polyamines (292159) if the specific phenylenediamine or diaminotoluene structure is not identified, or even with aromatic monoamines (292149) if the 'polyamine' aspect is missed.
