2.    For the purpose of manufacturing cast iron powder, borings and turnings (7204.10) or cast iron granules (72.05) are received as inputs. Impurities are removed from the inputs by passing it through an electrically operated magnetic separator. Since some particles, oxides etc. are fused with the metals, these are subjected to the process of pulverisation and finally passed through sieves of various sizes to separate powder as per their sizes. The resultant product is cast iron powder and is reportedly used for chemical reaction in order to generate hydrogen gas and required for reduction purposes.

3.    The matter has been examined by the Board. attention is drawn to Section Note 6(a) and (b) of Section XV which contain the definition of wastes and scrap and powders. Further, Chapter Note i(h) of chapter 72 defines granules. Although granules and powders of pig  iron, spiegeleise, iron or steel are classifiable under heading 72.05 yet granules, powders and waste and scrap have their own specific definitions and are known distinctly in end use and character. The Board is, therefore, of the view that conversion of cast iron granules/ cast iron turnings and borings into cast iron powder amounts to manufacture for the purpose of Section 2(f) of Central Excises & Salt Act, 1944 and that cast iron powder so manufactured is dutiable again.
