27.08 Pitch and pitch coke, obtained from coal tar or from other mineral tars.
The pitch covered by this heading is a residue of the distillation of either high temperature coal tars or other mineral tars. It contains a small proportion of heavy tar oils. It is black or brown in colour and may be soft or brittle. It is used in the manufacture of electrodes, road tars, waterproofing mixtures, for agglomerating coal dust, etc.
Pitch which has been slightly modified by air blowing is similar to unblown pitch and remains in this heading.
Pitch coke is the final residual product left from the distillation of either high temperature or low temperature coal tars or of other mineral tars or of their pitches. It is used for making electrodes or as a fuel.
