No Bond is nothing but Rebate which means, as and when, dutiable goods are moved out of excisable plant, the exporter has to pay the duty amount immediately. This is Excise rule and I am not sure, whether you are aware of this. This being the case, why you want immediate refund ?
that is the sum of the 3 excise duties, and not affect the net price
Your above statement is not clear. You should be knowing the excise values are statutory amount and should be posted to FI who in turn, will submit periodical excise returns. Having said this, obviously, this will have impact on your net price value.
Better if you explain clearly what is the business requirement, may be some alternate suggestions can be given. But my request would be have a brainstorming with clients' finance / excise team before posting further queries here
