About HS Code 292144

This HS code covers diphenylamine (DPA) and its derivatives, including their salts. Diphenylamine is a crucial aromatic monoamine primarily valued for its antioxidant properties, making it indispensable in the rubber and plastics industries, particularly for tires and other elastomeric products. It also serves as an intermediate for the synthesis of dyes, pharmaceuticals, and explosives. Trade involves chemical companies supplying DPA and its derivatives to tire manufacturers, polymer producers, and specialty chemical sectors globally. Importers seek DPA for its ability to inhibit oxidation and polymerization, extending product lifespan. Exporters are typically large chemical producers. Key trade considerations include purity, specific derivative, and compliance with environmental and safety regulations.

Products Under This Code

Diphenylamine, N-nitrosodiphenylamine, 4-hydroxydiphenylamine, Diphenylamine hydrochloride, Alkylated diphenylamines, Octylated diphenylamine

Real World Examples

Lanxess (DPA-based antioxidants), Eastman (DPA derivatives), Kumho Petrochemical (rubber chemicals), Sinopec (DPA production), Sumitomo Chemical (specialty chemicals)

Common Misclassification

Could be confused with other aromatic monoamines (292149) or even aromatic polyamines (292159) if the specific diphenylamine structure, with two phenyl groups attached to a nitrogen, is not clearly identified.
