Creosote Oils (Coal Tar Origin)

Creosote oils distilled from high-temperature coal tar, classified under 2707910000, are the dominant wood preservative used in railroad ties, utility poles, and marine pilings in the United States. EPA regulates creosote as a restricted-use pesticide, and importers must ensure that foreign-origin creosote meets applicable EPA registration and labeling requirements before distribution. Belgium and Canada are the leading suppliers, with Denmark and India also among source countries. The relatively small number of active coal tar distillation facilities worldwide keeps the supplier base concentrated.
