Waste oil not dutiable under residuary tariff entry where no specific excise classification covered it.

Waste oil cleared after use of lubricating oil, cutting oil and coolants was held not chargeable to central excise duty under Heading 2710.90 because duty under Section 3 of the Central Excise Act must be supported by a specific tariff entry. The Tribunal found no chapter note or heading in the tariff that expressly covered waste oil, and held that a residuary petroleum entry could not be stretched to include it merely because it was a residue. Relying on the larger bench view, the Tribunal treated the absence of a clear tariff provision as decisive and rejected the Revenue's challenge.

Issues: Whether waste oil cleared after use of lubricating oil, cutting oil and coolants was chargeable to central excise duty under Heading 2710.90, and whether the Revenue was entitled to succeed on the basis of Rule 57S(2)(c) of the Central Excise Rules, 1944.

Analysis: The Tribunal held that levy of duty must rest on a specific tariff entry under Section 3 of the Central Excise Act, 1944, and that the tariff did not contain any specific chapter note or heading defining or separately covering waste oil. Heading 2710.90, being a residuary entry under petroleum oils, could not be extended to cover waste oil merely because the item was described as residue. The Tribunal agreed with the view that the cited larger bench ruling supported the conclusion that waste oil was not exigible to duty in the absence of a clear tariff provision.

Conclusion: Waste oil was not liable to central excise duty under the tariff entry invoked, and the Revenue's challenge to the appellate order failed.
