Hi,
The requirement you have mentioned above seems very strange, since in depot we don't perform any manufacturing activity. Hence we cannot charge any extra duty.
Normally we use a depot for storage purpose only (a warehouse) and we have to pass on the same excise duty amounts to the customer whatever is applicable in the manufacturing plant. However the sales price can be different.
Also in Depot, there wont be G/L or accounting impacts for excise transactions as we cannot avail any excise credit.
Hope it is clear.
Thanks n Regards,
