Understanding Letters of Credit: Functions, Types and Pros/Cons

What is a Letter of Credit in International Trade?

A letter of credit (L/C) is a bank's payment guarantee to sellers upon document compliance in global logistics.

Letters of credit secure transactions between unfamiliar parties in cross-border shipments.

Under ICC UCP 600 rules, banks honor payments if documents match L/C terms precisely.

In 2025, L/Cs adapt to new tariff codes for smoother logistics flows.

Key Functions of Letters of Credit in Logistics

Letters of credit ensure payment security and risk reduction in international logistics.

• Guarantee exporter payment upon verified shipment documents.
• Reduce non-payment risks from distant buyers.
• Enable financing options like deferred payments.
• Standardize processes across global supply chains.
• Support compliance with 2025 HS code requirements.

These functions make L/Cs vital for high-value freight shipments.
