Cyclic hydrocarbons; toluene

HS v2017 Code: 290230

About cyclic hydrocarbons; toluene

HS code 290230 covers the classification of cyclic hydrocarbons, specifically toluene. Toluene is a widely used aromatic hydrocarbon compound that plays a crucial role in various industries, including chemical manufacturing, fuel production, and the production of other organic compounds. As a key industrial solvent and feedstock, toluene's importance extends across the global economy, making it a significant component of international trade and import/export activities.

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 using catalytic reforming units, where the feedstock, usually a naphtha fraction, is heated and exposed to a catalyst under controlled conditions to enhance the formation of toluene and other aromatic hydrocarbons.

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 feedstock, as well as specialized catalysts, process equipment such as distillation columns and reactors, and energy sources to power the refining operations. Additionally, the production of toluene may require other auxiliary materials, such as hydrogen, for the catalytic reforming process.

Production outputs

The primary output of HS code 290230 is toluene, a versatile aromatic hydrocarbon with a wide range of applications. Toluene is used as a solvent, a fuel additive, and a feedstock for the production of other organic compounds, such as 290243 benzene, toluene, and xylenes, 290244 mixed xylene isomers, and 292090 other organic compounds. The toluene produced under this code may be further processed or blended with other materials to meet the specific requirements of various industries and end-users.
