Last updated: April 2026 dataCoal tar creosote oils, classified under a single tariff line (2707910000), are complex mixtures of polycyclic aromatic hydrocarbons used primarily as wood preservatives for railroad ties, utility poles, and marine pilings. Belgium leads US imports under this heading, with Canada, Denmark, and India also among the top suppliers. EPA regulates creosote as a restricted-use pesticide when applied as a wood preservative, and importers should confirm that product end-use and labeling comply with FIFRA requirements before distribution.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
Yes. Creosote used as a wood preservative is regulated under the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) as a restricted-use pesticide. Importers and distributors must ensure the product is registered with EPA, properly labeled, and sold only to certified applicators. Unregistered creosote cannot legally be sold or distributed for pesticidal use in the US.
Creosote oils under HTS 2707910000 must originate from coal tar distillation. Wood creosote (derived from beechwood or other wood tars) is a chemically distinct product classified elsewhere. Additionally, if a coal tar fraction is blended or processed to the point where it no longer resembles a distillation cut, CBP may question whether it remains classifiable under 2707 or should move to another chapter. Supplier documentation confirming coal tar origin and minimal processing is advisable.
