More Specific Codes
This product may fall under a more specific subheading:
Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If the product is primarily a rubber accelerator rather than an anti-oxidant
Rubber accelerators are classified separately in heading 3812, and the product's function determines the subheading.
If the product acts as a compound plasticizer for rubber or plastics
Compound plasticizers are a distinct category within heading 3812, separate from anti-oxidizing preparations.
If the product is a chemical preparation not specifically covered by heading 3812
Other chemical products not elsewhere specified may fall under heading 3824.

Import Tips & Compliance
• Ensure the product is declared as an anti-oxidizing preparation for rubber, not as a separate chemically defined compound, to avoid misclassification
• Provide a safety data sheet (SDS) to the CBSA if requested, as rubber chemicals may be subject to health and safety review
• Verify whether the polymer-bound phenol content affects any excise or environmental levies
