Due to one customer stopping business with us we have some qty of Finish Goods stuck up in our in-house Bonded FG Store. This non-moving material can't be dispatched to any other customer in the same condition. However more than 90% of the components of the said product are common with some other customer doing business with us now. If we rework the goods by changing about 10% components to make it suitable to current customer we can use the non-moving inventory. Is there a provision to remove Finished Goods from in-house Bonded store for such modification? If yes what procedure do we have to follow to avoid violating any excise laws?
