Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If flame retardants alter monomer predominance
High additive content may shift classification to unspecified styrene polymers.
If fluoro-containing FR system
Fluoropolymer additives trigger classification under fluoropolymer subheadings.
If pre-compounded into sheets
Non-cellular sheets/plates of polymers classified by end form, not primary resin.

Import Tips & Compliance
• Include UL yellow cards and flame test reports with commercial invoice
• Confirm brominated vs non-brominated flame retardant systems for EPA compliance
• Package separately from standard SAN to prevent confusion with higher-duty compounds
