High Molecular Weight Polyethylene Resin HMWPE-1440 from Mexico
This is a high molecular weight polyethylene (HMWPE) resin with a relative viscosity of 1.50, specific gravity below 0.94, supplied in primary pellet form for extrusion and molding applications. It falls under HTS 3901.10.1000 because it is a polyethylene polymer in primary form meeting the relative viscosity criterion of 1.44 or more, as per subheading notes requiring 95% or more ethylene monomer content.

Import Tips
• Verify relative viscosity certification from manufacturer as Customs may test samples; provide detailed monomer composition data showing ≥95% ethylene units; avoid misclassification by distinguishing from lower viscosity LDPE in 3901.10.50
