ITC on damaged product

We had sold our finished goods @ 18% to customer. In transit, the goods was damaged and return to plant and we issue credit note and reverse our Output Tax Liability. After survey by insurance company it was decided to sale these goods as it is on scrap @ 5%. Now we pay GST @ 5% on scrap value. and the Rest amount received us without GST from insurance company after deduction as per insurance policy.

Now, My Question is: -
Whether we have reverse to credit taken on Raw Material ? If yes How much i.e. on Scrap Qty. or balance Qty. or proportionate Amount received from Insurance Co. ?
