Cyclic hydrocarbons

HS v2022 Code: 2902

About cyclic hydrocarbons

HS code 2902 covers a diverse range of cyclic hydrocarbons, which are organic compounds consisting entirely of carbon and hydrogen atoms arranged in a closed ring structure. These compounds play a crucial role in the chemical industry, serving as building blocks for a wide array of products, from fuels and solvents to plastics and pharmaceuticals. Their importance extends across various sectors, making them a vital component of the global economy.

Production process

Cyclic hydrocarbons are primarily produced through a process known as catalytic reforming, which involves the conversion of straight-chain hydrocarbons into more complex aromatic compounds. This process typically involves the use of a catalyst, high temperatures, and pressure to rearrange the molecular structure of the feedstock. Additionally, some cyclic hydrocarbons may be extracted from crude oil or natural gas through distillation and other separation techniques.

Production inputs

The production of cyclic hydrocarbons requires a range of raw materials, including 2709 Petroleum oils and oils obtained from bituminous minerals, crude, natural gas, and various other hydrocarbon feedstocks. Additionally, the process relies on specialized equipment, such as catalytic reformers, distillation columns, and other processing units. The availability and quality of these inputs are crucial for the efficient and cost-effective production of cyclic hydrocarbons.

Production outputs

The cyclic hydrocarbons produced under HS code 2902 have a wide range of applications and are consumed by various other industries. These compounds are used as solvents, fuel additives, and as feedstocks for the production of 2902 Cyclic hydrocarbons, 2903 Halogenated derivatives of hydrocarbons, and 2907 Phenols; phenol-alcohols, among other products. The versatility of cyclic hydrocarbons makes them an essential component of the global chemical supply chain.
