For the shortfall in realisation of export proceeds, you have to approach your bank, seeking a write-off. In that case, the provisions of sub-para (iv) of Para C.23 of RBI FED Master Direction no. 16/2015-16 dated January 1, 2016 (as amended), dealing with export of goods and services will come into play. It permits banks to allow a write-off provided the exporter has surrendered proportionate export incentives, if any, availed of in respect of the relative shipments. The AD Category-I bank should obtain documents evidencing surrender of export incentives availed of before permitting the relevant bills to be written off.
