Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If styrene monomer units predominate over petroleum
Styrene-acrylonitrile where styrene > other units shifts to 3903.20 per predominance rule.
If sold as self-adhesive plates in retail packs
Processed into adhesive sheets/plates moves to 3919 self-adhesives.

Import Tips & Compliance
• Document copolymer ratio proving aromatic predominance per note (a)(2)
• Declare as primary granules, not adhesive compounds
• Common issue: undervaluation in adhesive trade names
