Polymethylpentene PMP Resin from China
Polymethylpentene (PMP), or poly(4-methyl-1-pentene), is a high-clarity olefin polymer imported as granules. Since the 4-methyl-1-pentene monomer exceeds 95% by weight, it is classified as 'other' olefin polymers under tariff item 3902.90.00, as it is not specifically named in other subheadings of heading 39.02.

Import Tips
• Ensure the PMP is in primary forms (granules) and that the 4-methyl-1-pentene monomer content is above 95% by weight
• Keep technical data sheets showing the polymer composition for CBSA review
• Consider whether the product could be classified under a more specific subheading if it contains copolymers with other monomers
