Cyclic hydrocarbons; toluene

HS v2022 Code: 290230

About cyclic hydrocarbons; toluene

HS code 290230 covers cyclic hydrocarbons, specifically toluene. Toluene is a widely used chemical compound that plays a crucial role in various industries, including the production of fuels, solvents, and chemical intermediates. As a key component in the petrochemical industry, toluene's importance extends across the global economy, making it a vital commodity in international trade.

Production process

Toluene is primarily produced through the catalytic reforming of petroleum fractions, a process that involves the rearrangement of hydrocarbon molecules to increase the proportion of aromatic compounds. This is typically done in specialized refineries, where the raw materials undergo a series of distillation, hydrogenation, and isomerization steps to extract the desired toluene fraction.

Production inputs

The main inputs required for the production of toluene under HS code 290230 include crude oil or natural gas liquids, which serve as the primary feedstock. Additionally, the process requires specialized refining equipment, such as catalytic reformers, distillation columns, and hydrogenation units. Energy sources, such as electricity and natural gas, are also essential for powering the various stages of the production process.

Production outputs

The primary output of HS code 290230 is toluene, a clear, colorless liquid hydrocarbon. Toluene finds widespread use as a solvent, fuel additive, and chemical intermediate in the production of various 290240 xylenes, 290260 ethylbenzene, and 290270 cumene, which are all classified under different HS codes. Toluene is also a key component in the manufacture of 292090 other organic compounds used in the pharmaceutical, agrochemical, and plastics industries.
