Letter of Credit
Also known as: L/C, LC, Documentary Credit
A letter of credit is a written undertaking by a bank, issued at the request of a buyer, to pay a seller a defined amount provided the seller presents documents that strictly comply with the terms stated in the credit. By substituting the creditworthiness of a bank for that of the buyer, a letter of credit gives the exporter strong assurance of payment while assuring the importer that payment will be released only against evidence that the goods were shipped as agreed. It is the workhorse of higher-risk international trade, governed by internationally accepted banking rules, and it makes payment contingent on documents rather than on the goods themselves.
Banks deal in documents, not goods. A credit pays against a compliant presentation: if the documents match, the bank pays even when the cargo is wrong; if they do not, the bank refuses even when the cargo is perfect. Most first-time discrepancies are trivial and self-inflicted — a date, a spelling, a missing copy.
Where it matters for compliance
- Payment terms do not change customs value, but the documents a credit generates often evidence it.
