Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If degree of polymerization too low
Low MW versions treated as heterocyclic compounds rather than polymers.
If for saturated polyester variants
Saturated allyl polyesters fall under different unsaturated/saturated split.
If when imported as synthetic rubber modifier
End-use as rubber chemical may trigger Chapter 38 classification.

Import Tips & Compliance
• Provide GC-MS analysis confirming allyl monomer dominance for audit-proof entries
• Declare molecular weight to distinguish from monomers
• Avoid reclassification by ensuring no co-monomers exceed trace levels
