Coal Tar Creosote for Wood Preservation
Creosote is a dark, oily liquid distilled from coal tar, consisting wholly of polycyclic aromatic hydrocarbons (PAHs) naturally found in coal tar. It is used primarily as a wood preservative for railroad ties, utility poles, and marine pilings to protect against rot and insects. Classified under HTS 3824.99.21.00 because it contains 5% or more aromatic substances entirely derived from natural coal tar components.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If unrefined or crude coal tar pitch
Crude tar oils and pitch fall under Chapter 27 as mineral fuels/products before chemical processing.
If bitumen-emulsion mixtures for road surfacing
Petroleum bitumen preparations shift to Chapter 27 when not purely coal tar substances.
If containing less than 5% aromatic substances
Drops out of the aromatic subheading into general chemical mixtures NESOI.
