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.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If linear low-density with specific density and comonomer limits
Linear low density polyethylene (LLDPE) with narrow molecular weight distribution and specific branching meets 3901.10 criteria over the general 'other'.
If low-density polyethylene (LDPE)
LDPE with density 0.917-0.941 g/cm³ and high-pressure polymerization process is specifically provided for in 3901.20.
If ethylene-vinyl acetate copolymer predominates
Copolymers where vinyl acetate units exceed ethylene by weight fall under polymers of vinyl acetate in 3902.90.

Import Tips & Compliance
• Verify monomer content exceeds 95% ethylene by weight per subheading note (a)(1) to avoid reclassification into 3901.10 or 3901.20
• Provide detailed technical data sheets confirming it's in primary form (pellets/resin) not further processed into articles (Chapter 39 headings 3901-3926)

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.
