Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If used for molded products
Specific end-use polyethylenes for molding have statistical suffixes differentiating from copolymer resins.
If in silicone rubber form
Silicones are distinct polymers outside ethylene chapter.
If imported as non-cellular film sheets
Finished plates/sheets/films of polymers classify in 3920 regardless of base resin.

Import Tips & Compliance
• Comply with FDA indirect food contact regs; provide GRAS status or equivalent for resin
• Document alpha-olefin as butene specifically to avoid generic copolymer disputes
• Prevent dust formation in shipping to maintain 'primary form' status

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.
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.
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.
Hexene-Comonomer LLDPE Pellets
High-performance LLDPE pellets using 1-hexene as alpha-olefin comonomer, specific gravity <0.94, for heavy-duty sacks and liners. Supplied in virgin primary form. Meets exact definition under 3901.40.00.00 for low-density copolymers.
VLDPE (Very Low Density Polyethylene) Resin
VLDPE resin, an ultra-low density ethylene-alpha-olefin copolymer (SG <0.94, often 0.88-0.91), used for elastic films and sealants in primary pellet form. Alpha-olefin like 1-octene provides elastomeric properties. Directly covered by HTS 3901.40.00.00 specificity.
Food-Grade LLDPE Copolymer Pellets
Pellets of LLDPE ethylene-alpha-olefin copolymer with specific gravity <0.94, certified food-safe for primary packaging conversion. Meets strict purity for direct food contact. HTS 3901.40.00.00 applies to this primary polymer form.
