Import Tips
• Request detailed technical data sheets confirming homopolymer status to meet 95% styrene monomer requirement
• Label shipments clearly as 'primary forms' to prevent confusion with finished articles in 3923
• Avoid bulk packaging without ventilation specs, as styrene can off-gas and trigger hazmat declarations
