https://www.taxtmi.com/caselaws?id=167187 A tariff levy on semi-finished steel billets was treated as including both the fixed component and the excise duty leviable on steel ingots, even where the billets were made directly from scrap without an intermediate ingot stage, because the duty referred to a notional ingot within the tariff structure. An amending exemption notification inserting an Explanation for products made in electric furnaces from specified scrap materials was treated as substantive and prospective only, since retrospective exemption could not be implied without clear statutory authority. On that basis, the levy was sustained and retrospective exemption was refused. en-us Mon, 27 Aug 1984 00:00:00 +0530 Wed, 10 Dec 2014 16:48:23 +0530 TaxTMI RSS Generator https://www.taxtmi.com/caselaws?id=167187 A tariff levy on semi-finished steel billets was treated as including both the fixed component and the excise duty leviable on steel ingots, even where the billets were made directly from scrap without an intermediate ingot stage, because the duty referred to a notional ingot within the tariff structure.
