About HS Code 381231

This specific category covers anti-oxidising preparations and compound stabilisers for rubber or plastics, specifically those based on mixtures of oligomers of 2,2,4-trimethyl-1,2-dihydroquinoline (TMQ). TMQ is a highly effective antioxidant widely used in the rubber industry, particularly for tires, conveyor belts, and other products requiring excellent heat aging and fatigue resistance. These preparations prevent degradation caused by oxygen, heat, and ozone, thereby extending the lifespan and maintaining the performance of rubber and plastic articles. Manufacturers of tires, automotive components, and industrial rubber goods are primary consumers. Importers and exporters are typically specialized chemical companies and distributors. The trade focuses on high-performance applications where durability under harsh conditions is paramount. Understanding the specific oligomeric composition and its impact on processing and end-product properties is key. Regulatory aspects, especially regarding food contact or specific environmental standards, can also influence market demand and trade flows for these specialized stabilizers.

Products Under This Code

TMQ antioxidant powder, Liquid TMQ blends, Rubber anti-aging agents, Polymer heat stabilizers, Ozone resistance additives, Fatigue resistance compounds, Vulcanization retarders (secondary effect), UV light stabilizers (secondary effect)

Real World Examples

Naugard Q, Vulkanox HS, Antioxidant TMQ, Wingstay 29, Lowinox TMMQ

Common Misclassification

This code is distinct from 381239 because it specifically covers TMQ oligomers; confusion might arise if other types of anti-oxidants are mistakenly classified here, or if the product is a raw chemical (e.g., 2,2,4-trimethyl-1,2-dihydroquinoline monomer) rather than a prepared mixture.

Products Classified Under 3812.31

Industry

This code belongs to the Chemicals industry.

Trade Overview

China, USA, Germany, Japan, and Thailand are key players in the import and export of these specialized TMQ-based stabilizers due to their large rubber and tire industries.
