Sir, as per Rule 4 (5) of CCR 2004 - if the inputs or capital goods, as the case may be, are not received back within the time specified under sub-clause (i) or (ii), as the case may be, by the manufacturer or the provider of output service, the manufacturer or the provider of output service shall pay an amount equivalent to the CENVAT credit attributable to the inputs or capital goods, as the case may be, by debiting the CENVAT credit or otherwise, but the manufacturer or the provider of output service may take the CENVAT credit again when the inputs or capital goods, as the case may be, are received back in the factory or in the premises of the provider of output service. Thus you need to reverse the Cenvat credit. But since it is two decade now the condition of reversal of cenvat credit by 2.5% per quarter would not apply here. Thus in my view you have to pay Excise Duty on transaction value. This is my view. I also welcome views of my collegue experts. Thanks.
