Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If polyisobutylene predominates
Specific olefin polymers have dedicated subheadings based on monomer per note (a).
If extruded into rigid tubes pre-import
Finished tubes/pipes of plastics classify under heading 3917, not primary polymers.
If heavily filled with additives
Preparations where polymer is matrix but not sole characteristic fall to Chapter 38.

Import Tips & Compliance
• Certify density and crystallinity specs; use ISPM-15 compliant packaging for pellets
• Pitfall: moisture absorption in transit affects quality claims
• Declare as 'primary form' explicitly

Isotactic Polypropylene Homopolymer
A high-molecular-weight isotactic polypropylene homopolymer where propylene monomer units constitute over 95% by weight, produced via Ziegler-Natta catalysis for superior crystallinity. Classified under HTS 3902.10.00.00 as it meets the subheading note (a)(1) for polymers prefixed 'poly' with predominant monomer content. Used in injection molding for rigid containers and automotive parts.
Polypropylene Impact Copolymer (ICP)
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.
Metallocene Polypropylene Homopolymer
A narrow molecular weight distribution polypropylene homopolymer (>95% propylene units) produced using metallocene catalysts for films and fibers with uniform properties. HTS 3902.10.00.00 applies via subheading note (a)(1) for pure propylene polymers in primary forms like pellets. Ideal for BOPP film production.
Clarified Polypropylene Homopolymer
