Letter of Credit (LC) for Exporters: Complete Guide

Last updated 6 October 2026
Quick answer

A letter of credit (LC) is a bank's undertaking to pay the exporter once the exporter presents documents that comply with the LC's terms. Most LCs follow the ICC's UCP 600 rules. The bank checks documents, not goods, so payment depends on the invoice, transport document, insurance and other papers matching the LC exactly.

Types of LC

  • Sight LC: payment when compliant documents are presented
  • Usance LC: payment at a future date, for example 60 or 90 days after the bill of lading
  • Confirmed LC: a second bank, often in India, also guarantees payment, useful when the issuing bank or country is a risk

Documents usually required

  • Commercial invoice and packing list
  • Bill of lading or air waybill
  • Insurance certificate, if the terms are CIF or CIP
  • Certificate of origin, inspection or quality certificates
  • Bill of exchange, where called for

How to avoid discrepancies

  • Check the draft LC before it is issued and ask for changes to terms you cannot meet
  • Copy names, addresses and goods description exactly as written in the LC
  • Ship within the latest shipment date and present within 21 days of shipment, unless the LC says otherwise, and before expiry
  • Make sure all documents agree with each other
