Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If the acrylonitrile content exceeds 5% by weight
SAN scrap with significant acrylonitrile content falls under other plastic waste.
If the scrap is converted into primary forms
Reground SAN pellets are classified under primary forms of styrene polymers.

Import Tips & Compliance
• Obtain a polymer composition certificate from the supplier to confirm styrene content is at least 95% by weight
• If acrylonitrile content exceeds 5%, the scrap may be classified elsewhere
• Ensure the scrap is free from moisture or contaminants that could affect customs classification
