Ethylene polymers; in primary forms, n.e.c. in heading no. 3901

HS code 390190 covers a diverse range of ethylene polymers in their primary forms, excluding those more specifically classified under other headings in Chapter 39. These polymers are essential materials in the plastics industry, with applications spanning packaging, construction, automotive, and numerous other sectors. As a key component of the broader petrochemicals industry, the production and trade of these ethylene polymers play a vital role in the global economy.

Ethylene polymers classified under HS 390190 are typically produced through polymerization of ethylene gas. This process involves the use of catalysts to facilitate the linking of ethylene monomers into long-chain polymer molecules. The specific production techniques may vary depending on the desired properties of the final product, such as density, molecular weight, and degree of branching. Common methods include high-pressure, low-pressure, and solution polymerization.

The primary raw material for the production of HS 390190 ethylene polymers is ethylene gas, which is typically derived from the cracking of natural gas or petroleum. Other key inputs include catalysts, such as Ziegler-Natta or metallocene catalysts, as well as various additives and processing aids to impart specific characteristics to the final polymer. Specialized production equipment, such as polymerization reactors, extruders, and pelletizers, are also essential for the manufacturing process.

The ethylene polymers classified under HS 390190 are used in a wide range of applications, including 390110 Polyethylene; linear low density, in primary forms, 390120 Polyethylene; high density, in primary forms, and 390130 Ethylene-vinyl acetate copolymers, in primary forms. These polymers are further processed and converted into a variety of end-products, such as packaging materials, construction materials, automotive components, and various consumer goods.
