Waste and scrap are not dutiable without proof of manufacture, tariff coverage, and traceable excisable inputs.

Waste and scrap arising from civil construction, cables, refractory bricks and furnace oil sludge were held not liable to central excise duty unless the department proved that the items were excisable goods covered by the tariff and generated from dutiable inputs. The commentary applies the principle that mere clearance as waste does not attract duty; manufacture under section 2(f) and specific tariff coverage must be established. On the facts noted, the source of the scrap was not proved, no specific entry covered the refractory brick waste or sludge, and the disputed duty, interest and penalty were therefore unsustainable.

Issues: (i) whether waste and scrap of iron and steel generated during civil construction were liable to central excise duty where credit had not been taken on the bulk of the steel material used; (ii) whether copper and aluminium waste arising from cables on which credit was taken under the relevant credit rule was dutiable under Chapters 74 and 76 of the tariff; (iii) whether used refractory bricks cleared as scrap were chargeable to duty under Heading 6309.90 or any other tariff entry; and (iv) whether furnace oil sludge cleared by the appellant was classifiable and dutiable under Heading 2710.90.

Issue (i): whether waste and scrap of iron and steel generated during civil construction were liable to central excise duty where credit had not been taken on the bulk of the steel material used.

Analysis: The governing principle applied was that scrap arising in the course of civil construction is not dutiable where it is shown to have arisen from steel on which no Modvat credit was taken, and the department must establish the source of the scrap by evidence rather than assumption. The quantity of scrap cleared was far higher than the quantity of credit-availed material, and there was no evidence that the entire scrap was generated from inputs on which credit had been taken.

Conclusion: The issue was decided in favour of the assessee and the iron and steel scrap was held not liable to duty.

Issue (ii): whether copper and aluminium waste arising from cables on which credit was taken under the relevant credit rule was dutiable under Chapters 74 and 76 of the tariff.

Analysis: The relevant inputs were copper and aluminium cables falling under Chapter 85, and the waste arising from those cables could not be treated as scrap under Chapters 74 and 76 merely because it was waste. The decision also followed the principle that waste and scrap of wires and cables are not excisable when no specific tariff entry covers them as dutiable goods in the manner asserted by the department.

Conclusion: The issue was decided in favour of the assessee and no duty was held payable on the copper and aluminium scrap.

Issue (iii): whether used refractory bricks cleared as scrap were chargeable to duty under Heading 6309.90 or any other tariff entry.

Analysis: The decisive consideration was that the tariff contained no specific entry covering waste of refractory bricks as dutiable goods, and in the absence of such coverage the scrap could not be treated as excisable merely because it was cleared as waste.

Conclusion: The issue was decided in favour of the assessee and the refractory brick waste was held not dutiable.

Issue (iv): whether furnace oil sludge cleared by the appellant was classifiable and dutiable under Heading 2710.90.

Analysis: The conclusion turned on the requirement that a product must answer the statutory concept of manufacture under Section 2(f) of the Central Excise Act, 1944 and be specifically covered by the tariff before duty can be levied. Sludge was treated as industrial waste and not as a manufactured excisable product merely because it was sold.

Conclusion: The issue was decided in favour of the assessee and no duty was held payable on the sludge.

Final Conclusion: The demands of duty, interest, and penalty were unsustainable because the disputed materials were not shown to be excisable goods chargeable under the tariff provisions invoked.

Ratio Decidendi: Waste and scrap are not liable to central excise duty unless the department proves, with evidence, that they are excisable goods generated from dutiable inputs or otherwise specifically covered by the tariff, and the statutory concept of manufacture must also be satisfied.
