Frequently Asked Questions
1. What is a Letter of Credit in international trade?
A Letter of Credit (L/C) is a bank-issued document that guarantees payment to the seller upon presentation of specified documents. It provides security for both the buyer and seller in international transactions.
2. What is the difference between L/C at sight and usance L/C?
L/C at sight pays immediately upon presentation of documents. Usance L/C (deferred payment) pays at a specified later date (e.g., 30, 60, 90 days after shipment).
3. Is L/C the best payment term for pellet machines?
L/C is preferred for high-value equipment like pellet machines, especially for new business relationships. It provides security for both parties. For trusted relationships, T/T with deposit may be more cost-effective.
4. Who pays the L/C costs?
L/C costs are typically shared: the buyer pays opening fees; the seller pays advising and discrepancy fees. The specific allocation should be negotiated.
5. What documents are typically required for L/C?
Commercial invoice, packing list, bill of lading, certificate of origin, insurance certificate, and inspection certificate. Additional documents may be required depending on product and destination.
6. What happens if documents have discrepancies?
Discrepancies result in payment delays and discrepancy fees. The bank may reject the documents, or the buyer may accept them with amendment fees.
7. How long does an L/C transaction take?
From L/C application to payment: approximately 4-8 weeks, including L/C issuance (1-2 weeks), production (4-12 weeks), shipment, document presentation, and payment processing.
8. Is L/C more expensive than T/T?
Yes, L/C is more expensive. Costs include bank fees, confirmation fees, and discrepancy fees. However, the additional security may justify the cost for high-value transactions or new relationships.
