📦 What is LC (Letter of Credit)? Complete Guide for Exporters & Importers
Introduction
In international trade, one of the biggest concerns for both buyers and sellers is payment security. This is where a Letter of Credit (LC) plays a crucial role.
If you are an exporter or importer, understanding LC can help you reduce risk, secure payments, and build trust in global trade.

📌 What is a Letter of Credit (LC)?
A Letter of Credit (LC) is a financial guarantee issued by a bank on behalf of the buyer (importer), ensuring that the seller (exporter) will receive payment on time and in full.
👉 In simple words:
LC = Bank guarantee for payment in international trade

🎯 How Does LC Work? (Step-by-Step Process)
Here’s how a typical LC transaction works:
- Buyer and seller agree on trade terms
- Buyer requests their bank to issue an LC
- Issuing bank sends LC to seller’s bank
- Seller ships the goods
- Seller submits required documents
- Bank verifies documents
- Payment is released to seller
📌 Important:
Payment is made based on documents, not physical goods

👥 Key Parties in a Letter of Credit
- Applicant: Buyer (Importer)
- Beneficiary: Seller (Exporter)
- Issuing Bank: Buyer’s bank
- Advising Bank: Seller’s bank

Understanding different types of LC is important:
1. Sight LC

2. Usance LC
- Payment is made after a specific period (30, 60, 90 days)
