Hi All , I am Rohan
I have query on Central Excise -
Our company has recently got registration under Central Excise [ECC] on 20/11/20009
Now we have many purchases before registration from 01/04 - 20/11/2009
Most of them are charged with excise duty, can i avail Modvat of the Duty
paid for such purchases, is there any provision in Excise to take set off of the same. Do revert back ASAP

Thanks in advance
