Oils and products of the distillation of high temperature coal tar; xylol (xylenes)

HS v2017 Code: 270730

About oils and products of the distillation of high temperature coal tar; xylol (xylenes)

HS code 270730 covers a range of products derived from the distillation of high-temperature coal tar. These oils and related compounds are essential inputs for various industries, including chemicals, pharmaceuticals, and construction materials. As a key component of the broader coal tar processing sector, this industry plays a vital role in the global economy, providing critical raw materials for a diverse array of downstream applications.

Production process

The production of the goods covered by HS code 270730 primarily involves the distillation of high-temperature coal tar. This process separates the tar into its constituent fractions, including aromatic hydrocarbons such as xylenes. Advanced refining and purification techniques are then employed to isolate the desired products, ensuring they meet the necessary quality and purity standards for their intended uses.

Production inputs

The main inputs required for the production of HS code 270730 goods are high-temperature coal tar, which serves as the primary feedstock. Additionally, the industry relies on specialized distillation and refining equipment, as well as a range of chemical reagents and catalysts to facilitate the separation and purification of the target compounds.

Production outputs

The primary outputs of this industry are the various oils and aromatic hydrocarbons derived from the distillation of high-temperature coal tar. These include xylenes, which are widely used as solvents and in the production of 290243 phthalic anhydride, as well as other aromatic compounds that find applications in the 290290 organic chemical industry.
