Propylene, other olefin polymers; polyisobutylene in primary forms

HS code 390220 covers the production and trade of propylene and other olefin polymers, as well as 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 sector, this industry plays a vital role in the global economy, supporting the manufacture of countless consumer and industrial products.

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 are synthesized through the polymerization of ethylene, propylene, and other olefin monomers. Polyisobutylene is produced through the cationic polymerization of isobutylene. These processes often require specialized equipment, catalysts, and carefully controlled conditions to ensure the desired molecular structure and properties of the final products.

The main inputs for this industry include raw materials such as crude oil, natural gas, and various petrochemical feedstocks. Specialized machinery, including reactors, distillation columns, and polymerization equipment, are also essential. Additionally, the industry relies on a skilled workforce, energy sources, and a robust transportation and logistics network to support the production and distribution of these materials.

The outputs of this industry are primarily used as intermediate goods in the manufacture of a wide range of products. Propylene, olefin polymers, and polyisobutylene are commonly used in the production of 390110 Polyethylene in primary forms, 390210 Polypropylene in primary forms, and 390750 Alkyd resins, in primary forms, among other 3902 Polymers of propylene or other olefins, in primary forms and 3907 Polyacetals, other polyethers and epoxide resins, in primary forms; polycarbonates, alkyd resins, polyallyl esters and other polyesters, in primary forms.
