About heading 3812
Prepared rubber accelerators; compound plasticizers for rubber or plastics, not elsewhere specified or included; antioxidizing preparations and other compound stabilizers for rubber or plastics
Heading 3812 covers three families of rubber and plastics additives: prepared rubber accelerators, compound plasticizers, and anti-oxidizing preparations and other compound stabilizers. The heading splits first by product family (3812.10, 3812.20, 3812.31 and 3812.39), then by whether the preparation contains an aromatic or modified aromatic ingredient, and finally by named chemical identity for stabilizers.

Frequently asked questions
What is the HTS code for prepared rubber accelerators?
Prepared rubber accelerators containing any aromatic or modified aromatic rubber accelerator are classified in 3812.10.10.00 at a general (MFN) rate of 6.5%. Other prepared rubber accelerators go in 3812.10.50.00 at a general (MFN) rate of 5%.
What is the duty on anti-oxidizing preparations for rubber?
The rate depends on the chemical identity and aromatic content. For example, 3812.39.90.00 carries a general (MFN) rate of 5%, while 3812.31.00.00 (TMQ oligomer mixtures) carries a general (MFN) rate of 6.5%.
How do I classify compound plasticizers for plastics?
Compound plasticizers containing any aromatic or modified aromatic plasticizer go in 3812.20.10.00 at a general (MFN) rate of 6.5%. All other compound plasticizers for rubber or plastics go in 3812.20.50.00 at a general (MFN) rate of 5%.
