Ethylene polymers; in primary forms, ethylene-alpha-olefin copolymers, having a specific gravity of less than 0.94

HS code 390140 covers a crucial category of ethylene polymers known as ethylene-alpha-olefin copolymers. These materials are widely used in a variety of industries, from packaging and construction to automotive and consumer goods. Their unique properties, such as low specific gravity and excellent mechanical and chemical resistance, make them indispensable in many modern applications. This industry plays a significant role in the global economy, supporting diverse manufacturing and processing sectors.

Ethylene-alpha-olefin copolymers are typically produced through a process called copolymerization. This involves the reaction of ethylene with another alpha-olefin, such as butene, hexene, or octene, in the presence of a catalyst. The specific catalyst and reaction conditions are carefully controlled to achieve the desired molecular structure and properties. The resulting copolymer is then processed into various primary forms, such as pellets, granules, or powders, ready for further transformation into end-use products.

The main inputs for the production of ethylene-alpha-olefin copolymers under HS code 390140 include ethylene, the alpha-olefin co-monomer, and specialized catalysts. Ethylene is typically sourced from the petrochemical industry, while the alpha-olefin co-monomers may be derived from various sources, including 290123 Propene and 290124 Butenes. The catalysts used in the copolymerization process are often complex organometallic compounds that require specialized manufacturing and handling. Additionally, energy, water, and other utilities are necessary for the production and processing of these materials.

The primary output of HS code 390140 is ethylene-alpha-olefin copolymers in various primary forms, such as pellets, granules, or powders. These materials are then consumed by a wide range of industries, including 392010 Plastic packing goods, e.g. bags, sacks, containers, boxes, cases, cartons, 392020 Plastic articles for the conveyance or packing of goods, 392030 Carboys, bottles, flasks and similar articles, 392041 Other plates, sheets, film, foil and strip, of polymers of ethylene, and 392042 Other plates, sheets, film, foil and strip, of polymers of propylene. The versatility of these copolymers allows them to be further processed and transformed into a diverse array of end-use products.
