Understanding Letters of Credit in International Commodity Trade

The Letter of Credit (L/C) is the gold standard payment method in international commodity trade. It provides security for both buyer and seller by involving banks as trusted intermediaries.

What is an Irrevocable L/C?

An irrevocable Letter of Credit is a financial instrument issued by the buyer's bank, guaranteeing payment to the seller upon presentation of compliant shipping documents. Unlike revocable L/Cs, an irrevocable L/C cannot be modified or cancelled without the consent of all parties.

How It Works in Commodity Trade:

1. Buyer and seller agree on trade terms (price, quantity, quality specs, Incoterms)
2. Buyer's bank issues the L/C in favor of the seller
3. Seller's bank (advising bank) verifies and forwards the L/C
4. Seller ships the goods and presents documents to their bank
5. Banks verify documents against L/C terms
6. Payment is released upon compliance

Key L/C Terms for Commodity Buyers:

• At Sight: Payment is made immediately upon document presentation
• Usance (Deferred): Payment after a specified period (30, 60, 90 days)
• Confirmed: An additional bank guarantee, useful for transactions with banks in developing countries

Common Pitfalls to Avoid:

• Document discrepancies (wrong product description, HS code mismatch, date errors)
• Late presentation of documents (typically must be within 21 days of B/L date)
• Missing or expired certificates
• Inconsistent information across documents
