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.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If specific gravity 0.94 or higher
Higher density copolymers shift to linear polyethylene heading based on physical properties overriding copolymer specifics.
If chemically modified with additives exceeding note thresholds
Modifications place it in 'other' polyethylene subheadings if not predominantly ethylene-alpha-olefin per subheading note (a)(3).
If processed into paraffin wax-like form
Waxy forms derived from polyethylene are classified as petroleum waxes, not primary polymers.

Import Tips & Compliance
• Verify specific gravity certification from manufacturer, as it must be below 0.94 for this classification; test reports may be required by CBP
• Provide detailed copolymer composition data (e.g
• % alpha-olefin) to confirm 95% ethylene-alpha-olefin content per subheading notes
• Avoid misclassification as polyethylene wax by ensuring melt index aligns with resin specs, not wax forms
