Rule 57CC inapplicable to exempt product derived from waste mother liquor; no reversal of common input credit required.

Where mother liquor arose as waste in the manufacture of dutiable gelatin, no excise duty was payable on its clearance and full Modvat credit on hydrochloric acid used as a common input remained available. Rule 57CC could not be invoked merely because that waste was later processed into exempt Di-Calcium Phosphate, since the waste mother liquor was not treated as a final product attracting reversal of credit or a presumptive payment. The Tribunal followed the binding High Court view and held that no duty or credit reversal was required on the exempt product derived from the waste mother liquor.

Issues: Whether the assessee was liable to pay the presumptive amount under Rule 57CC on exempt Di-Calcium Phosphate obtained by further processing mother liquor generated in the manufacture of dutiable gelatin using a common input.

Analysis: The applicable principle was that where mother liquor arises as waste in the manufacture of dutiable gelatin, no excise duty is payable on its clearance and the assessee is entitled to avail full credit on hydrochloric acid used as common input under the Modvat scheme. Once Rule 57CC was held inapplicable at the stage of clearance of the waste mother liquor, it could not be applied merely because the waste was later processed into another exempt product. The Tribunal followed the binding High Court view that the waste mother liquor was not a final product and therefore did not attract any obligation to reverse credit or pay the presumptive amount.

Conclusion: The assessee was not liable to pay duty or reverse credit under Rule 57CC on the exempt product derived from the waste mother liquor.

Ratio Decidendi: Rule 57CC does not apply where the exempt product is derived from waste mother liquor generated during manufacture of a dutiable product, and no reversal of common input credit is required in such a situation.
