The decisive principle applied was that a waste or rejected product can still be excisable if it is identifiable in commercial parlance by a marketable name and has an established market. On that basis, the residue could not be excluded from excisability merely because it arose as a by-product of the manufacturing process. en-us Fri, 21 May 1993 00:00:00 +0530 Wed, 06 Jul 2011 12:53:12 +0530 TaxTMI RSS Generator https://www.taxtmi.com/caselaws?id=82616 Caustic lye generated during oxygen manufacture was treated as excisable under Tariff Item 68 because it was not merely worthless waste but a spent caustic solution with utility in the assessee's own tube-manufacturing unit and some market presence.
