Ethylene-Butene Copolymer Granules
Granules of ethylene-butene copolymer (plastomer grade) with 97% ethylene for stretch films. HTS 3901.90.90.00 applies as 'other' since butene <5%, not specific LDPE/LLDPE. Classification by predominant ethylene monomer weight.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If butene-specific LLDPE grades
Certain butene LLDPE fits 3901.10.50 narrow molecular weight specs.
If non-cellular sheet/film from this resin
Extruded into finished polymer sheets/films moves to 3920 plates/films.
If pure butene monomer import
If butene content separated, classifies as acyclic hydrocarbons not polymer.

Import Tips & Compliance
• Provide GPC (gel permeation chromatography) data showing molecular weight distribution
• Ensure granules <6mm to confirm primary form, avoiding parts classification

Medium-Density Polyethylene (MDPE) Pellets
Medium-density polyethylene pellets have a density range of 0.926-0.941 g/cm³, used for pipe and film production. Classified in 3901.90.90.00 as 'other' ethylene polymers not qualifying for specific density-based subheadings like LDPE or HDPE. Subheading notes dictate classification by predominant monomer when not fitting named polymers.
Ethylene-Propylene Copolymer Resin
Random ethylene-propylene copolymer resin with 98% ethylene for injection molding. Falls in 3901.90.90.00 'other' as propylene comonomer minor (<5%); note (a)(1) prefix 'poly' requires 95%+ named monomer.
UV-Stabilized Ethylene Polymer Pellets
Ethylene homopolymer pellets with <1% UV stabilizers for outdoor applications. Chemically modified per note (a)(3) thus 3901.90.90.00 'Other'; base ethylene >95% retains polymer identity.
Metallocene Polyethylene Resin
Metallocene-catalyzed polyethylene resin with uniform molecular weight for high-clarity films. 3901.90.90.00 as 'other' ethylene polymer; catalyst process doesn't create separate subheading.
Antistatic Ethylene Copolymer Pellets
Ethylene copolymer with antistatic agents (<2%) for electronics packaging resin. Note (a)(3) chemically modified to 3901.90.90.00 'Other'; retains ethylene polymer status.
Flame-Retardant Polyethylene Resin
PE resin compounded with halogen-free flame retardants (<3%) for wire insulation. 3901.90.90.00 per modification note (a)(3); primary form classification.
