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%.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If predominantly chemical preparations/additives
Masterbatches with >50% non-polymer additives classify as chemical preparations, not polymers.
If unmodified base LLDPE resin
Without chemical modification documentation, defaults to base polymer density classification.
If primary function is synthetic organic coloring pigment
Pigment concentrates shift to Chapter 32 if colorants predominate over polymer carrier.

Import Tips & Compliance
• List all additives <5% total with CAS numbers; excess may trigger predominant comonomer analysis
• Certify as 'primary form for further processing' not ready-for-use color concentrate

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.
