A letter of credit replaces trust with documents, and on a first order with a new supplier that trade is often worth making. The bank pays against paper rather than against the goods, which protects both sides until the relationship has a track record. The cost is a fee, a pile of conditions, and a real risk of payment delay if a single document does not match.
The mechanics are consistent across banks. The buyer’s bank issues the credit, the seller ships and presents documents – invoice, bill of lading, packing list, certificate of origin, inspection certificate where required – and the issuing bank pays if the documents comply strictly with the credit terms. Strictly is the operative word: banks examine documents, not cartons, and a discrepancy is a discrepancy whether or not the goods themselves are fine.
Types matter for cost and risk. A sight credit pays on presentation; a usance credit pays at a stated future date, which is financing for the buyer and a cost for the seller. A confirmed credit adds a second bank’s undertaking, useful where the issuing bank’s country risk is a concern. Transferable credits let an intermediary pass the credit to a supplier, which comes up in trading company structures.
The discrepancies that delay payment repeat across the trade. Shipment after the latest shipment date. A bill of lading showing a port different from the credit. An invoice description that paraphrases the credit instead of copying it. A packing list that omits a detail the credit requires. Missing signatures, wrong number of copies, an insurance certificate dated after shipment. None of these are commercial problems, and all of them cost days.
Soft clauses are the clauses that quietly turn a credit into something weaker. A credit requiring a certificate of inspection signed by a named person who has not been appointed, or a document only the buyer can issue, gives the buyer a switch to stop payment. Reading the credit for clauses that depend on the buyer’s action is more useful than reading the price.
For packaging orders, the documents that cause friction are often the inspection certificate and the bill of lading. The first depends on a third-party inspector’s availability and wording; the second depends on the carrier’s timing. Where an inspection is part of the credit, the inspector should be booked against the production schedule rather than after the goods are packed.
Amendments cost money and time, and they can restart the clock. A credit amended after shipment is a classic trap: the goods are on the water, the amendment is in process, and the documents no longer match either version. Getting the credit right before production starts is cheaper than fixing it afterwards, which means the sales contract terms and the credit terms have to be written together.
Against a deposit and balance arrangement, the LC costs more and protects more. For a first order of meaningful value with a new counterparty, the protection is usually worth it. For repeat orders with a supplier that has shipped cleanly several times, the fee and administration often exceed the risk being managed. The payment structure that suits a packaging order is covered in the payment terms FAQ for deposits and balance.
Where an LC is used, the export documents have to be produced to the credit rather than to habit. That means a checklist derived from the credit itself, a review before the documents leave the exporter, and a named person responsible for the presentation. Nearly all discrepancies are catchable in a ten-minute review against the credit text, and the document sequence on an export order is set out in the export order management guide.
Banks charge for discrepancies as well as for the credit, and repeated discrepancies can affect the relationship. A supplier that presents clean documents repeatedly gets faster processing and occasionally better terms. The incentive is administrative rather than commercial, and it is real.
This is general information rather than banking advice. Credit terms, fees and discrepancy practices vary by bank and jurisdiction, and the Uniform Customs and Practice for Documentary Credits governs how banks interpret the documents. Confirm the specifics with your bank before structuring a transaction.
