Oils and products of the distillation of high temperature coal tar; naphthalene

HS v2017 Code: 270740

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

HS code 270740 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 integral to the global supply chain, supporting industries such as pharmaceuticals, plastics, dyes, and more.

Production process

The main production technique for HS code 270740 involves the distillation of high-temperature coal tar. This process separates the tar into various fractions, each containing a unique blend of aromatic hydrocarbons and other chemical compounds. The naphthalene fraction, in particular, is a key output of this industry and is further refined and processed for use in various end-products.

Production inputs

The primary inputs required for the production of HS code 270740 items are high-temperature coal tar, which is a by-product of the coking process in steel production. Additionally, the industry relies on specialized distillation equipment, as well as energy sources and utilities to power the production facilities. Skilled labor, including chemical engineers and technicians, is also a critical input for this industry.

Production outputs

The main outputs of the HS code 270740 industry are the oils and products derived from the distillation of high-temperature coal tar, including naphthalene. These outputs are then consumed by a variety of downstream industries, such as 290270 Naphthalene for the production of dyes, plastics, and other chemicals, as well as 271500 (Bituminous mixtures based on natural asphalt, on natural bitumen, on petroleum bitumen, on mineral tar or on mineral tar pitch (e.g., bituminous mastics, cut-backs)) for use in road construction and other applications.
