Renewal of 57 f4

You have reverse the credit if capital goods are not returned within 180 days. But you can take the credit again when the goods are received. Else, you can show that the goods the returned within 180 days and again sent  out  by issuing fresh chalan.

Now the present rule for job work is Rule 4(5)(a) of CENVAT CREDIT RULES, and not 57F(4).

Goods cleared from the factory for job work, on which CENVAT  Credit has been availed, then it should come back to factory, within 180 days.  If not returned, then reversal of CENVAT credit is mandetory.  After receipt back of total qty. of goods, reversed CENVAT credit can be taken.

Other option is to send total qty. imported, directly to the job workers premises. After confirmation for receipt of goods by job worker, factory should send job work challan.  CENVAT credit should not be avail till total qty. returned back to factory.  This will avoid reversal & recredit of CENVAT credit.
