Creosote (coal tar oil) is used as Carbon Black Feed Stock (CBFS) – raw material in Carbon Black manufacturing.
The main purpose of use of  coal-tar creosote is wood preservation (vacuum pressure impregnation) for industrial purposes: electricity poles, railway ties, and sleepers, etc. No other wood treatment chemical can substitute creosote’s durable and strong quality effect; however creosoted wood has acknowledged harmful human health effects and environmental impact.
The process of vacuum pressure impregnation of wood with coal-tar creosote oil is called creosoting.
Coal tar creosote is famous in its stringent odor; rather say a powerful specific smell featuring traditional coal-tar creosote. Its smell is due to coal-tar creosote’ specific chemical composition. Coal-tar creosote is a mixture of diverse chemicals that are combined in four major classes of creosote compounds, see the table below Composition.

Composition and use of coal tar creosote is regulated in each country on its own. And these regulations are mainly applied to the content of benzo-a-pyrene (BaP) and phenols.
In Europe, all chemicals imported, to EU, produced and/or used in EU must be registered with ECHA and obtain a REACH registration number. In 2003 EEC with the aim of protecting human health and the environment in the European Member States decided restricting use of dangerous substances and coal tar creosote oil in particular. Restrictions on use of Creosote and creosoted wood imposed under the REACH regulations are described in detail in Annex XVII of the REACH Regulation  https://echa.europa.eu/substances-restricted-under-reach  (search for “creosote”)
