Linear Low-Density Polyethylene (LLDPE) Resin
LLDPE is an ethylene copolymer produced by copolymerizing ethylene with butene, hexene, or octene, where ethylene monomer units exceed 95% by weight. It is supplied in primary pellet form for extrusion into films and packaging. Classified under 3901.90.55.01 as it meets the specific ethylene copolymer criteria per subheading note (a)(2).

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If homopolymer without significant comonomers
Pure polyethylene homopolymers (no copolymers) without butene/hexene fall under 3901.10 for polyethylene in primary forms.
If ethylene content <95% or chemically modified
Polymers not meeting the 95% threshold for named copolymers go to the broader 'Other' ethylene polymers subheading.
If predominant monomer is propylene instead
If propylene units predominate by weight over ethylene, classification shifts to polymers of propylene under heading 3902.

Import Tips & Compliance
• Verify monomer composition via certificate of analysis to confirm ethylene units >95% by weight for this subheading
• Provide detailed technical data sheets showing copolymer type to avoid misclassification as generic polyethylene
• Watch for blends; if no single monomer predominates, it may shift to 'Other' under subheading rules
