Line of Credit terms tie export eligibility to the Foreign Trade Policy and require predominant Indian supply. A Government of India-supported Line of Credit from Exim Bank to Guyana for aircraft procurement ties eligible exports to the Foreign Trade Policy and requires that a substantial percentage of contract value be supplied from India while allowing a residual portion to be sourced abroad; shipments must be declared on prescribed export documentation, disbursements follow the LoC timeline, and no agency commission is payable from the LoC though exporters may remit commission from their own foreign exchange subject to post realisation rules.
