Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If the resin contains less than 95% allyl monomer units by weight
Other polyesters, not unsaturated, would apply if the allyl content does not meet the threshold.

Import Tips & Compliance
• Ensure the resin is in primary form (e.g
• liquid, powder, granules) and uncompounded to qualify for this tariff item
• Declare the exact polymer composition, as the 95% allyl monomer content is critical for classification
• Keep technical datasheets and certificates of analysis available for CBSA verification
