Metallocene LLDPE (mLLDPE) Pellets
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.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If ethylene-vinyl acetate copolymer dominant
Specific named copolymers like EVA have dedicated subheadings if vinyl acetate exceeds alpha-olefin predominance.
If blended with >5% other polymers
Polymer blends not meeting 95% purity rule classify under 'other' based on predominant monomer per subheading note (a)(4).
If for industrial-grade polypropylene blends
If propylene monomer predominates in blend, shifts to polypropylene polymers.

Import Tips & Compliance
• 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

Linear Low-Density Polyethylene (LLDPE) Resin
LLDPE resin is an ethylene-alpha-olefin copolymer produced via copolymerization of ethylene with alpha-olefins like 1-butene or 1-hexene, resulting in a specific gravity below 0.94 and enhanced flexibility compared to LDPE. It is supplied in primary pellet form for conversion into films and packaging materials. Classified under HTS 3901.40.00.00 due to its specific gravity and copolymer composition meeting the 95% monomer contribution rule.
Octene-Based LLDPE Granules
Granules of LLDPE copolymerized with 1-octene offer low specific gravity (<0.94) and high tensile strength, ideal for agricultural films in primary form. The ethylene and octene units comprise over 95% by weight. Precisely matches HTS 3901.40.00.00 criteria for alpha-olefin copolymers.
