https://www.taxtmi.com/caselaws?id=76058 In manufacture of sewing thread from cotton yarn, duty was held payable at the single ply yarn stage, because doubling and waxing were treated as part of the sewing thread manufacturing process and did not defer excise liability to the later stage. Non-accountal of captively consumed yarn in statutory records and returns supported a finding of wilful suppression, so the extended period of limitation was invocable. Penalty under Section 11AC was sustained, subject to re-quantification after recomputing duty and interest on the correct duty stage, but the separate penalty under Rule 25 was set aside. en-us Thu, 03 Sep 2009 00:00:00 +0530 Sat, 05 Jun 2010 00:00:00 +0530 TaxTMI RSS Generator https://www.taxtmi.com/caselaws?id=76058 In manufacture of sewing thread from cotton yarn, duty was held payable at the single ply yarn stage, because doubling and waxing were treated as part of the sewing thread manufacturing process and did not defer excise liability to the later stage.
