2708 - Pitch and pitch coke, obtained from coal tar or from other mineral tars:

HTS category 2708 encompasses pitch and pitch coke derived from coal tar or other mineral tars. Pitch, in this context, refers to the viscous, black residue remaining after the distillation of coal tar or similar mineral oils. Pitch coke is the solid carbonaceous material produced by the carbonization of pitch. These products are typically characterized by their high carbon content and are often black or dark brown in appearance.

This category is distinct from other mineral products found in Section V. Unlike mineral fuels or oils (Chapter 27), pitch and pitch coke are processed residues rather than primary fuels. They also differ from waxes or other bituminous substances by their specific origin from tars and their resultant physical and chemical properties. For instance, while other bituminous substances might be used for paving or roofing, the primary applications for pitch and pitch coke are often as binders in electrodes, coatings, or as a carbon source in metallurgical processes.

Within category 2708, two primary subcategories exist to differentiate between the physical forms of the product. Subcategory 2708.10.00.00 covers "Pitch," referring to the semi-liquid or viscous form. Subcategory 2708.20.00.00, "Pitch coke," denotes the solid, coke-like material resulting from the further processing of pitch. This distinction is crucial for accurate classification based on the state and form of the material presented for import or export.
