3901.40.00.00 - Ethylene-alpha-olefin copolymers, having a specific gravity of less than 0.94

HTS Code 3901.40.00.00 encompasses ethylene-alpha-olefin copolymers specifically characterized by a specific gravity of less than 0.94. These copolymers are distinct from other polyethylene forms within heading 3901 due to their unique composition, which includes alpha-olefins in addition to ethylene. This combination imparts specific physical properties, such as enhanced flexibility, tear resistance, and low-temperature performance, making them suitable for a range of specialized applications.

This category differentiates itself from its siblings by its defined copolymer structure and low specific gravity. Unlike pure polyethylene classified under 3901.10 (specific gravity less than 0.94) or 3901.20 (specific gravity 0.94 or more), these materials are not solely composed of ethylene monomers. Furthermore, they are distinct from ethylene-vinyl acetate copolymers (3901.30) which have vinyl acetate as the comonomer. The "Other" category (3901.90) would typically include any remaining ethylene polymers not specifically described elsewhere within the heading.

As a leaf node, HTS 3901.40.00.00 has no further subdivisions. Therefore, classification within this code relies solely on meeting the defined criteria: being an ethylene-alpha-olefin copolymer with a specific gravity below 0.94. Examples of products falling under this classification include certain types of linear low-density polyethylene (LLDPE) and very low-density polyethylene (VLDPE), often used in the production of films, flexible packaging, wire and cable insulation, and molded articles where enhanced flexibility and toughness are required.
