Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If acrylonitrile content <95% with other monomers
Copolymers not specifically named fall under 'Other polymers of styrene' based on predominant monomer weight.
If supplied as powder rather than pellets
Petroleum resins and similar polymer powders have different primary form classifications.
If for PVC/SAN blends
Blends classified by predominant vinyl chloride monomer under PVC copolymer headings.

Import Tips & Compliance
• Request supplier FTIR spectroscopy reports confirming SAN copolymer structure to prevent reclassification during customs exam
• Check for REACH compliance documentation if originating from EU suppliers
• Label containers clearly as 'SAN Copolymer - Primary Form' to avoid confusion with finished articles in Chapter 39 headings 3920+
