Cenvat credit on molasses allowed when used as input in dutiable manufacture, subject to unit structure and usage. Cenvat credit on duty paid on molasses is permitted or denied based on use and organisational structure: in a composite unit, credit is unavailable where molasses is consumed to produce exempted or non-excisable ethyl alcohol, while credit on externally procured molasses used to make dutiable ethyl alcohol is available for duty on any finished product of the same factory; where sugar and distillery are separate entities, duty paid on molasses cleared by the sugar unit yields no credit for that unit but the receiving distillery may avail the credit.
