Products classified under HTS 3901.90.90.00
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.
Blow Molding Grade PE Pellets
Specialty polyethylene pellets optimized for blow molding bottles, ethylene >97%. General 'other' classification 3901.90.90.00 as not density-specific.
Slip Agent Modified PE Resin
Ethylene polymer with slip agents for low COF films, modified per note (a)(3). 3901.90.90.00 'Other' primary form.
High-Clarity Ethylene Copolymer Pellets
Copolymer pellets engineered for optical clarity in food trays, ethylene base >95%. 3901.90.90.00 general ethylene polymer.
High-Density Polyethylene (HDPE) Resin
High-density polyethylene resin is a polymer of ethylene with a density greater than 0.941 g/cm³, supplied in primary pellet form for extrusion and molding. It falls under HTS 3901.90.90.00 as an 'other' polymer of ethylene not specifically named in prior subheadings like 3901.10 (linear low density) or 3901.20 (low density). This classification follows subheading note (a) for polymers not meeting specific purity or density criteria.
Cross-Linked Polyethylene (PEX) Resin
Cross-linked polyethylene resin undergoes chemical modification for enhanced heat resistance, used in plumbing pipes. It falls under 3901.90.90.00 per subheading note (a)(3) as chemically modified polymers classified in 'Other' unless more specific. Primary form pellets distinguish it from finished PEX tubing.
Ethylene-Octene Copolymer Pellets
Ethylene-octene copolymer with ethylene >95% by weight provides elastomer properties for flexible packaging. Classified 3901.90.90.00 as 'other' ethylene polymer since octene comonomer <5%, not meeting specific copolymer subheadings. Predominant ethylene monomer controls per note (a)(4).
Chemically Modified HDPE Masterbatch
HDPE masterbatch with chemical modifiers (antioxidants, UV stabilizers) at low levels for color concentration. Per subheading note (a)(3), chemically modified polymers go to 'Other' (3901.90.90.00) unless more specific. Remains ethylene polymer as base >95%.
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.
Recycled Polyethylene Resin Pellets
Post-consumer recycled polyethylene pellets from mixed HDPE/LDPE sources, ethylene predominant. Classified 3901.90.90.00 as 'other' ethylene polymers in primary form; recycling doesn't change polymer classification per notes.
