Import Tips
• Include end-use statement specifying SBR copolymerization to distinguish from general styrene imports
• Monitor acetaldehyde content (<10 ppm) per ASTM D5135; excess impurities may affect classification purity
• Coordinate with TSCA importer of record requirements for new chemical notifications if modified grades
