Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If contains reinforcing agents or colorants
Any compounding with non-polymer additives classifies as 'other' allyl resins.
If for petroleum resin blends
Hydrocarbon polymer blends follow different series classification rules.
If used primarily as varnish base with pigments
Pigment-dispersed polymer solutions may classify as paints/varnishes.

Import Tips & Compliance
• Ensure SDS and CoA specify 'uncompounded allyl resin' with no fillers to stay in this subheading
• Label containers clearly as primary form polymers
• Pitfall: resins pre-mixed with catalysts may go to 3907.91.40
