Impact-Modified SAN Copolymer Granules
Impact-modified SAN copolymer granules with rubber modification for improved toughness in appliance components. The chemical modification does not change the classification under 3903.20.00, as the core styrene-acrylonitrile units remain predominant.

More Specific Codes
This product may fall under a more specific subheading:
Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If the rubber modification results in acrylonitrile-butadiene-styrene (ABS) copolymers
ABS copolymers are classified under a different subheading when the comonomer composition changes.
