Acyclic hydrocarbons; unsaturated, propene (propylene)

HS v2017 Code: 290122

About acyclic hydrocarbons; unsaturated, propene (propylene)

HS code 290122 covers the classification of propene (also known as propylene), a key unsaturated acyclic hydrocarbon. Propene is a colorless, flammable gas with a wide range of industrial applications, making it an important commodity chemical within the global petrochemicals industry. As a fundamental building block for numerous downstream products, the production and trade of propene plays a significant role in supporting economic activity across various sectors.

Production process

Propene is primarily produced as a by-product during the steam cracking of naphtha or natural gas liquids (NGLs) in petrochemical refineries. The steam cracking process involves heating these hydrocarbon feedstocks to high temperatures, causing them to break down into smaller molecules, including propene. Propene is then separated from the other cracked products through a series of distillation and purification steps.

Production inputs

The main inputs required for the production of propene under HS code 290122 include naphtha or NGLs as the primary hydrocarbon feedstock, as well as steam, electricity, and specialized equipment such as steam crackers, distillation columns, and storage tanks. Refineries and petrochemical plants that have the necessary infrastructure and technical capabilities are the key producers of propene.

Production outputs

Propene produced under HS code 290122 is a versatile chemical that serves as a feedstock for the manufacture of a wide range of downstream products, including 390210 Polypropylene, 290230 (Propene (propylene)), 291512 Acetic anhydride, and 290531 Propyl alcohol and isopropyl alcohol. These products find applications in the plastics, textiles, pharmaceuticals, and other industries, highlighting the importance of propene in supporting economic activity across multiple sectors.
