Oils and products of the distillation of high temperature coal tar; toluol (toluene)

HS v2017 Code: 270720

About oils and products of the distillation of high temperature coal tar; toluol (toluene)

HS code 270720 covers the oils and products derived from the distillation of high-temperature coal tar. This industry plays a crucial role in the broader chemical and energy sectors, providing essential raw materials and intermediates for a wide range of downstream applications. The production and trade of these coal tar-derived products are of significant economic importance, as they serve as building blocks for various industries, including pharmaceuticals, plastics, dyes, and fuel additives.

Production process

The main production technique for HS code 270720 involves the distillation of high-temperature coal tar. This process separates the tar into its various components, including toluene, benzene, and other aromatic hydrocarbons. The specific steps involved in this distillation process include heating the coal tar, condensing the resulting vapors, and then fractionating the condensed liquids to isolate the desired products.

Production inputs

The primary inputs required for the production of goods under HS code 270720 are high-temperature coal tar, which serves as the raw material. Additionally, the industry relies on specialized distillation equipment, such as fractionating columns and condensers, to effectively separate the tar into its constituent components. Energy sources, such as electricity or natural gas, are also necessary to power the distillation process.

Production outputs

The main outputs of the industry covered by HS code 270720 are the various oils and products derived from the distillation of high-temperature coal tar, including toluene (also known as toluol). These outputs are then consumed by a range of other industries, such as the 290230 Benzene, toluene, and xylenes industry, which uses toluene as a feedstock for the production of other chemicals and fuels.
