Cyclic hydrocarbons; benzene

HS v2022 Code: 290220

About cyclic hydrocarbons; benzene

HS code 290220 covers the classification of benzene, a widely used cyclic hydrocarbon compound. Benzene is a key raw material in the petrochemical industry, serving as a precursor for the production of a diverse range of chemicals and materials. Its importance extends across various sectors, including the manufacturing of plastics, resins, dyes, and pharmaceuticals, making it a vital component in the global economy.

Production process

Benzene is primarily produced through the catalytic reforming of petroleum fractions, a process that involves the rearrangement of hydrocarbon molecules to increase the aromatic content. This is typically done in refineries, where the benzene-rich stream is then separated and purified through distillation and other separation techniques to obtain the desired level of purity.

Production inputs

The production of benzene requires several key inputs, including crude oil or natural gas liquids as the primary feedstock, as well as specialized catalysts, energy sources, and processing equipment. Refineries and petrochemical plants are the main facilities responsible for the large-scale production of benzene, leveraging their integrated operations and infrastructure to efficiently convert hydrocarbon feedstocks into this valuable chemical building block.

Production outputs

Benzene is a versatile compound that serves as a precursor for a wide range of downstream products. It is used in the manufacture of 290511 styrene, 290243 cumene, and 290420 cyclohexane, which are further processed into various plastics, resins, and other materials. Benzene is also a key ingredient in the production of 290711 phenol and 290243 aniline, which are essential for the synthesis of numerous pharmaceuticals and other specialty chemicals.
