By-product clearances in integrated manufacturing: proportionate reversal of attributable credit is sufficient, not a separate 8% demand.

Where exempt clearances arise as a by-product in an integrated manufacturing process, reversal of credit attributable to common inputs is legally sufficient and a demand to pay 8% of the exempted value is not sustainable. The Tribunal treated Ammonium Sulphate as a by-product of steel manufacture rather than an independent final product for separate input-accounting purposes. Because the assessee had reversed the credit relatable to common inputs and electricity used for the by-product clearances, the higher demand and penalty could not be confirmed. The operative requirement was satisfied by proportionate reversal of attributable credit.

Issues: Whether, on the facts of the case, the assessee was required to pay an amount equal to 8% of the value of Ammonium Sulphate cleared at nil rate of duty, or whether reversal of proportionate credit attributable to common inputs was sufficient.

Analysis: The clearance of Ammonium Sulphate was treated as a by-product arising in an integrated steel plant and not as an independent final product in respect of which the input-accounting scheme under the relevant excise credit provisions was to be applied in the manner adopted by the adjudicating authority. The assessee had used common inputs and had reversed the credit relatable to the inputs and electricity attributable to the by-product clearances. The Board circular and the Tribunal decisions relied upon supported the view that, in such a situation, reversal of attributable credit is legally sufficient and a demand of 8% of the exempted value is not sustainable.

Conclusion: The demand based on 8% of the value of the exempted clearances was not sustainable; reversal of proportionate credit was sufficient, and the issue was answered in favour of the assessee.

Final Conclusion: The impugned demand and penalty were set aside because the assessee's reversal of attributable credit met the legal requirement for the exempt by-product clearances.

Ratio Decidendi: Where exempt clearances arise as a by-product in an integrated manufacturing process and the assessee reverses the credit attributable to common inputs, the statutory requirement to maintain separate accounts or pay 8% of the exempted value does not justify confirmation of the demand.
