Modvat credit and scrap exemptions: strict notification conditions defeat relief, extended limitation applies, and valuation is cum-duty.

Where Modvat credit had been taken on inputs, waste and scrap generated in processing was dutiable unless the relevant exemption notification was strictly satisfied. Aluminium waste and scrap qualified for exemption only up to 1-11-1987, and duty applied from 2-11-1987 after the notification was amended to require that no credit be taken on the inputs. For iron and steel waste and scrap, the exemption failed because credit had been availed on the inputs, so duty was payable. Non-filing of a classification list and clearance without duty supported the extended limitation period, and valuation was ordered on a cum-duty basis with penalty sustained.

Issues: (i) Whether aluminium waste and scrap was entitled to exemption under the relevant notification and, if so, for what period; (ii) Whether waste and scrap of iron and steel was eligible for exemption under the relevant notifications despite the availment of Modvat credit on inputs; (iii) Whether the extended period of limitation was invokable and whether the assessable value required recomputation on a cum-duty basis.

Issue (i): Whether aluminium waste and scrap was entitled to exemption under the relevant notification and, if so, for what period.

Analysis: Waste and scrap arising from the processing of inputs on which Modvat credit had been taken was duty-liable under the governing rule, subject only to exemption under a notification. The original exemption for aluminium waste and scrap was amended so as to make the benefit conditional upon no credit having been taken on the inputs from which the scrap arose. The processing of aluminium castings in the factory brought the scrap within the amended notification once that condition applied.

Conclusion: The exemption was available only up to 1-11-1987, and duty became payable on aluminium waste and scrap from 2-11-1987 onwards.

Issue (ii): Whether waste and scrap of iron and steel was eligible for exemption under the relevant notifications despite the availment of Modvat credit on inputs.

Analysis: The notifications governing iron and steel waste and scrap granted exemption only when the scrap arose from specified goods and the credit of duty on such goods had not been taken. The castings and forgings in question were treated as falling within the specified tariff description for the purpose of the notification. Since Modvat credit had been availed of on the inputs, the condition attached to the exemption was not satisfied.

Conclusion: The exemption under the notifications was not available for the iron and steel waste and scrap, and duty was payable.

Issue (iii): Whether the extended period of limitation was invokable and whether the assessable value required recomputation on a cum-duty basis.

Analysis: The assessee had not filed a classification list for the waste and scrap and had cleared it without duty and without reflecting the clearance in the statutory records, which supported the invocation of the extended period. As to valuation, the sale price of the scrap had to be treated as inclusive of duty for recomputation of assessable value. Penalty was upheld.

Conclusion: The extended period was rightly invoked, and the assessable value was directed to be recomputed on a cum-duty basis.

Final Conclusion: The demand and penalty were substantially sustained, with limited relief confined to recomputation of duty and allowance of the aluminium scrap exemption for the period prior to 2-11-1987.

Ratio Decidendi: Where Modvat credit has been taken on inputs, waste and scrap arising from their processing is dutiable unless a specific exemption notification is available and its conditions are strictly satisfied; failure to disclose such clearances can justify invocation of the extended limitation period.
