Lines of credit for export financing permit limited commission for after sales service with prior approval and specific reimbursement terms. Exim Bank provided Lines of Credit of USD ten million each to Zambia and BGK Poland to finance eligible exports, with specified last dates for opening letters of credit and disbursements. Shipments under these LOCs must be declared on GR/SDF forms. No agency commission is normally payable, but the Reserve Bank may allow up to five per cent commission for exports requiring after sales service, payable locally by deduction and reimbursed by Exim Bank at ninety per cent of invoice value minus commission; prior approval is required.
