Oils and other products of the distillation of high temperature coal tar; creosote oils

HS v2022 Code: 270791

About oils and other products of the distillation of high temperature coal tar; creosote oils

HS code 270791 covers a range of products derived from the distillation of high-temperature coal tar. These oils and related substances play a crucial role in various industries, including construction, wood preservation, and chemical manufacturing. As a key component of the broader coal tar processing sector, this classification code represents an important segment of the global import/export economy.

Production process

The production of the goods covered by HS code 270791 typically involves the distillation of high-temperature coal tar. This process separates the tar into its constituent fractions, allowing for the extraction of specific oils and other valuable products. The precise techniques may vary depending on the desired output, but generally involve fractional distillation, solvent extraction, and other purification methods.

Production inputs

The primary input for this industry is high-temperature coal tar, which is a byproduct of the coking process in steel production or the gasification of coal. In addition to the coal tar feedstock, the industry may require specialized equipment such as distillation columns, storage tanks, and processing infrastructure. Skilled labor and energy resources are also important inputs for the efficient operation of these facilities.

Production outputs

The main outputs of the HS code 270791 industry include creosote oils, naphthalene, anthracene, and other aromatic hydrocarbon fractions. These products find applications in a variety of downstream industries, such as 440310 Wood in the rough for wood preservation, 290290 Other cyclic hydrocarbons for chemical synthesis, and 270799 Other oils and products of the distillation of high temperature coal tar; similar products for further processing and refining.
