Chlorinated Polyethylene Elastomer (CPE) from China
CPE is produced by chlorination of polyethylene, creating an elastomeric polymer of halogenated olefins in primary forms like powder or pellets under HTS 3904.90.1000. Chlorine modification imparts rubber-like properties with the base olefin structure preserved. Commonly used for wire insulation and roofing membranes.

Import Tips
• Specify chlorination level (typically 25-40% chlorine) in technical data sheets for classification
• Ensure imports marked as 'elastomeric grade' vs thermoplastic grades under different subheadings
