Propylene, other olefin polymers; polyisobutylene in primary forms

HS code 390220 covers the production and trade of propylene, other olefin polymers, and polyisobutylene in their primary forms. These materials are essential building blocks for a wide range of industries, from plastics and packaging to automotive and construction. As a key component of the petrochemical industry, the 390220 product group plays a vital role in the global economy, supporting the manufacture of countless consumer and industrial goods.

The production of propylene, olefin polymers, and polyisobutylene typically involves complex chemical processes. Propylene is commonly derived as a by-product of oil refining or natural gas processing, while olefin polymers and polyisobutylene are synthesized through polymerization reactions. These processes often require specialized equipment, catalysts, and carefully controlled conditions to achieve the desired molecular structures and properties.

The main inputs for the 390220 industry include raw materials such as propylene, other olefin monomers, and various catalysts and additives. Sophisticated production machinery, including reactors, extruders, and purification systems, are also essential. Additionally, the industry relies on a reliable supply of energy, water, and other utilities to power the manufacturing processes.

The outputs of the 390220 industry are used as feedstock for a diverse range of downstream industries. Propylene, olefin polymers, and polyisobutylene are commonly used in the production of 390210 Styrene polymers in primary forms, 390230 (Acrylonitrile-butadiene-styrene (ABS) copolymers in primary forms), and 390290 Polymers of propylene or other olefins, in primary forms, n.e.c., among other plastic and rubber products. These materials are found in a wide array of consumer and industrial applications, from packaging and construction to automotive and electronics.
