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

HS v2017 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, from wood preservation to chemical manufacturing. As a key component of the broader coal tar processing sector, this classification code represents an important segment of the global chemicals and materials trade.

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, including various oils and other chemical compounds. The specific techniques used may vary depending on the desired output, but generally involve fractional distillation, solvent extraction, and other purification methods to isolate the target products.

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. Other key inputs may include energy sources, such as electricity or natural gas, to power the distillation and refining equipment. Specialized machinery and equipment designed for the handling and processing of coal tar and its derivatives are also essential for this industry.

Production outputs

The main outputs covered by HS code 270791 include creosote oils, naphthalene, anthracene, and other aromatic hydrocarbon compounds. These products find applications in a variety of industries, such as 440310 Wood in the rough for wood preservation, 290290 Other cyclic hydrocarbons for chemical manufacturing, and 380810 Insecticides, rodenticides, fungicides, herbicides, anti-sprouting products and plant-growth regulators, disinfectants and similar products.

Revisions to 270791

Classification codes are adjusted frequently. The code may have been revised or replaced between system versions. The table below shows the history (newest to oldest) of the code 270791. The most recent 1 version of this code (270791) is in the HS v2022 system:
