Polypropylene Impact Copolymer (ICP) from Japan

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
