Mineral tars are viscous, carbon-rich liquids derived from the destructive distillation of coal, lignite, or peat, and reconstituted tars are blended or reprocessed versions of these primary distillates. These materials serve as feedstocks for carbon black, electrode binders, roofing compounds, and specialty chemical synthesis, giving them a significant role in both the metallurgical and chemical industries. Canada is the leading supplier to the US, followed by Colombia, India, Mexico, and South Korea — a supplier mix spanning both neighboring trade partners and major coal-chemistry producers in Asia. Importers should be aware that coal tar products may be subject to EPA hazardous substance regulations and OSHA occupational exposure standards, which can affect handling, labeling, and storage requirements independent of customs classification.
