Export line of credit enables major contract funding via irrevocable letters of credit with specified documentation and reimbursement procedures. A line of credit to a foreign bank finances a substantial portion of Exim Bank approved export contracts denominated in U.S. dollars, subject to a minimum contract size, buyer advance payment and an irrevocable letter of credit for the balance. Letters of credit must comply with the Uniform Customs and Practice for Documentary Credits and be advised through designated negotiating bank offices. Negotiating banks pay beneficiaries in Indian Rupees against compliant shipment documents and are reimbursed by Exim Bank in U.S. dollars under prescribed conditions. The circular allocates bank charges, disclaims Exim Bank liability for negotiating banks, prescribes GR/SDF documentation, limits agency commission subject to conditions, lists eligible goods, and invokes powers under the foreign exchange statute.
