Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If the flame-retardant additives exceed 5% by weight or the SAN content falls below 95%
Other styrene polymers may apply when the copolymer does not meet the 95% threshold for SAN.

Import Tips & Compliance
• Ensure the pellets are in primary forms (e.g
• granules) and that SAN content is ≥95% by weight to qualify under 3903.20.00
• Provide a material safety data sheet (MSDS) and technical datasheet to CBSA if requested
• Verify any fire-retardant additives do not alter the polymer classification
