Polypropylene Impact Copolymer (ICP) from China
An impact-modified copolymer of propylene and ethylene where propylene units exceed 95% by weight, enhancing low-temperature toughness for applications like battery cases. Falls under HTS 3902.10.00.00 per subheading note (a)(1) as 'polypropylene' due to dominant monomer content. Primarily used in consumer electronics housings.

Import Tips
• Request supplier's FTIR or NMR analysis proving propylene dominance; declare exact comonomer ratios
• Pitfall: ethylene content >5% may trigger 3902.90 audit
• Ensure MSDS for hazmat compliance if granulated
