U.S. exports of Coal Tar Distillate Oils & Aromatic-Predominant Products (NES) (SITC 33525) totaled $77.2M in August 2026.
Importers of Coal Tar Distillate Oils & Aromatic-Predominant Products (NES) paid $99K in duties in August 2026, an average duty rate of 0.22% — duty actually collected as a share of the imports that cleared customs, not the published tariff schedule. Coal Tar Distillate Oils & Aromatic-Predominant Products (NES) imports of $43.3M in August 2026 ran 13% above the year-to-date monthly average of $38.2M.
Last updated: August 2026 dataHigh-temperature coal tar distillation yields a range of aromatic-rich oil fractions — including creosote oil, naphthalene oil, anthracene oil, and carbolic oil — that do not fall under the named aromatic chemicals (benzene, toluene, xylene) or pitch headings. These products serve as wood preservatives (creosote), carbon black feedstocks, and specialty chemical intermediates, but their PAH content subjects them to EPA and OSHA hazard communication requirements. The "NES" (not elsewhere specified) scope means importers must confirm the product is not more precisely classifiable as a named aromatic or pitch before applying this heading.

Yes. Creosote is a registered pesticide under EPA's Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) when used as a wood preservative, and its use is restricted to certified applicators. Importers bringing in creosote for wood treatment applications should confirm EPA registration status and end-use compliance. Additionally, creosote's PAH content triggers OSHA hazard communication and potentially EPA TRI reporting obligations.
If the imported product is a substantially pure, isolated aromatic compound (benzene, toluene, or a xylene isomer), it belongs under the specific named heading (33522, 33523, or 33524). This heading (33525) applies to complex coal tar distillate fractions where aromatic constituents predominate by weight but the product is not a named single compound. A detailed GC composition analysis is the standard tool for resolving borderline cases.
