HS Code for Antioxidants for plastics

HS code 381239 is designated for anti-oxidising preparations and other compound stabilisers specifically formulated for use with rubber or plastics. This classification is critical for distinguishing these chemical compounds from other additives or raw materials. The "other" in the description signifies that this code encompasses a broad range of antioxidant types, excluding only those that are mixtures of oligomers of 2,2,4-trimethyl-1,2-dihydroquinoline (TMQ), which are classified separately under HS 381231. These preparations are essential in the plastics industry to prevent degradation caused by oxidation, extending the lifespan and maintaining the performance characteristics of plastic products by inhibiting reactions with oxygen, heat, and UV radiation.

Products Included

• Hindered phenol antioxidants (e.g., Irganox 1010, Irganox 1076)
• Phosphite antioxidants (e.g., Irgafos 168)
• Thioester antioxidants (e.g., DSTDP, DLTP)
• Synergistic blends of primary and secondary antioxidants for plastics
• UV stabilisers that also provide antioxidant properties for plastic applications

Common Misclassification

A common point of confusion arises with HS code 381231, which specifically covers anti-oxidising preparations and compound stabilisers for rubber or plastics that are mixtures of oligomers of 2,2,4-trimethyl-1,2-dihydroquinoline (TMQ). The key differentiator is the specific chemical composition: 381231 is reserved for TMQ-based products, while 381239 covers all other types of antioxidants for rubber or plastics. Another potential misclassification could be with HS code 381210, which is for accelerators for rubber. While both are chemical additives for rubber, their functions are distinct: accelerators speed up vulcanization, whereas antioxidants prevent material degradation.

FAQ

What is the HS code for Antioxidants for plastics?

The HS code for antioxidants specifically designed for plastics, excluding TMQ-based mixtures, is 381239.

How do I distinguish between 381239 and 381231?

The distinction between HS 381239 and 381231 is based on the chemical nature of the antioxidant. HS 381231 is exclusively for anti-oxidising preparations that are mixtures of oligomers of 2,2,4-trimethyl-1,2-dihydroquinoline (TMQ). Conversely, HS 381239 covers all other anti-oxidising preparations and compound stabilisers for rubber or plastics that do not contain TMQ oligomers.
