Normally, proceeds of export of goods, other than those for which exporters have been permitted to offer commercial credit, (cf. paragraph 6A.16) have to be realised on the due date for payment or within six months from the date of shipment whichever is earlier (or 15 months from the date of shipment in respect of exports to Indian-owned warehouses established abroad with the permission of the Reserve Bank). In some cases, however, the overseas buyers may be seeking longer period for payment of proceeds of commodities which are normally exported from India on "cash" terms generally on the ground that remittances of proceeds are not permitted within 6 months or earlier by the buyers country, in view of its difficult balance of payments position. Exporters intending to export goods on such terms may submit their proposals in form ECT through their banks to the concerned regional office of Reserve Bank for consideration.
