Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If the pellets are actually acrylonitrile-butadiene-styrene (ABS) copolymers, not pure SAN.
ABS copolymers are classified under a different subheading, even if they are transparent.

Import Tips & Compliance
• Verify the pellets are in primary forms as defined in Chapter 39 note 6
• Keep records of the monomer composition to support classification
• If the pellets are mixed with other polymers, check if they qualify as a blend under the same subheading
