Products classified under HTS 3824.99.21.00
Pyrene Concentrate for Research
Pyrene, a polycyclic aromatic hydrocarbon isolated from coal tar, supplied as concentrate for organic electronics and research. Wholly coal tar natural substance per HTS 3824.99.21.00.
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.
Coal Tar Pitch for Electrode Manufacturing
Coal tar pitch is a residue from coal tar distillation, rich in aromatic compounds like naphthalene and anthracene naturally occurring in coal tar. It serves as a binder in producing carbon electrodes for aluminum smelting and graphite electrodes for steelmaking. Falls under HTS 3824.99.21.00 due to its exclusive composition of coal tar-derived aromatics exceeding 5% by weight.
Naphthalene Crystals from Coal Tar
Purified naphthalene crystals extracted from coal tar, a crystalline aromatic hydrocarbon used in mothballs, dyes, and plasticizers. Composed solely of this naturally occurring coal tar substance. HTS 3824.99.21.00 applies as it meets the >5% aromatic and wholly coal tar natural substance criteria.
Anthracene Oil for Dye Production
Anthracene oil is a coal tar fraction containing anthracene and phenanthrene, used to produce alizarin dyes and pharmaceuticals. Entirely composed of natural coal tar aromatics. Classified in HTS 3824.99.21.00 for its high aromatic content from coal tar sources.
Phenanthrene Flakes from Coal Tar
Phenanthrene flakes purified from coal tar middle oil fraction, used in synthesis of dyes, explosives, and resins. Consists wholly of this tricyclic aromatic hydrocarbon natural to coal tar. HTS 3824.99.21.00 due to aromatic composition and coal tar origin.
Coal Tar Naphtha Solvent
Light oil fraction from coal tar distillation containing benzene, toluene, and xylene, used as industrial solvents and thinners. Purely natural coal tar aromatics qualifying for HTS 3824.99.21.00.
