Letter of Credit (LC) – A Beginner’s Guide for Indian Exporters


📍 Introduction

If you’re an Indian exporter dealing with international buyers, you’ve probably come across the term Letter of Credit (LC). It’s one of the most trusted and widely used payment methods in global trade.

But how does it really work? Who guarantees the payment? And what documents do you need?

This guide breaks down everything you need to know about LCs — in simple, practical language for exporters like you.


💼 What is a Letter of Credit?

A Letter of Credit (LC) is a guarantee issued by a bank on behalf of a buyer (importer), promising to pay the seller (exporter) a specified amount as long as agreed documents are submitted.

✅ It protects both buyer and seller
✅ The bank acts as a trusted middleman
✅ Used when buyer and seller don’t know each other well


🔁 How Does an LC Work?

Here’s a simple flow of how an LC transaction works:

  1. Buyer & seller agree on LC payment terms
  2. Buyer asks their bank (Issuing Bank) to issue an LC
  3. LC is sent to seller’s bank (Advising Bank)
  4. Exporter ships goods and submits shipping documents
  5. Bank verifies the documents
  6. Payment is released to exporter
  7. Buyer receives goods and reimburses the bank

🏷️ Key Parties Involved

  • Applicant – The Buyer (Importer)
  • Beneficiary – The Seller (Exporter)
  • Issuing Bank – Buyer’s bank that issues the LC
  • Advising Bank – Exporter’s bank that receives & verifies LC
  • Negotiating Bank – Bank that checks documents and pays
