Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If the DPG is imported as a separate chemically defined compound rather than a prepared accelerator
Pure diphenyl guanidine is classifiable as a separate chemically defined organic chemical in Chapter 29, not as a prepared rubber accelerator.
If the product is formulated as a compound plasticizer for rubber
Compound plasticizers for rubber or plastics are classified separately under heading 3812.

The Tariff Assistant works through the GRI rules on your specific product to reach the right tariff item — and can price the duty on it in the same conversation.
Import Tips & Compliance
• Ensure the product is clearly labeled as a prepared rubber accelerator and not a separate chemically defined compound, as that could change classification
• Keep technical data sheets and certificates of analysis to support the tariff classification if questioned by CBSA
• Verify whether the DPG is in pure form or mixed with other substances, as this affects the applicable duty rate
