Metallocene LLDPE (mLLDPE) Pellets from Mexico
Metallocene-catalyzed LLDPE pellets are narrow molecular weight distribution ethylene copolymers with 1-octene, featuring specific gravity under 0.94 for superior stretch film properties. Used primarily in primary form before extrusion. Falls under 3901.40.00.00 as the alpha-olefin comonomer meets the 95% weight threshold.

Import Tips
• Include catalyst type and comonomer ratio in documentation to distinguish from conventional LLDPE if audited
• Ensure pellets are free of contamination; CBP may inspect for recycled content affecting purity classification
• Label with exact specific gravity to prevent reclassification during entry processing
