Every payment structure in international trade is an answer to one question: who is exposed while the goods and the money are travelling in opposite directions. The seller does not want to release control of cargo before being paid. The buyer does not want to release money before having control of cargo. The instruments below are the standard ways of splitting that gap. None of them is generous; each one allocates risk somewhere specific, and it is worth knowing where.
The documentary credit
An irrevocable documentary credit — a letter of credit — is an undertaking by the buyer's bank to pay the seller against presentation of a stated set of compliant documents. Its rulebook is the ICC Uniform Customs and Practice for Documentary Credits, UCP 600, supplemented in practice by the ISBP examination standards. Two properties matter to a buyer. First, the bank pays against documents, not against cargo: if the documents comply, the bank pays even where the buyer has a complaint about the goods, and if they do not comply, the bank may refuse even where the cargo is perfect. Second, the credit is independent of the sales contract, so anything the buyer wants protected must appear as a required document — an inspection certificate, a specific COA, a certificate of origin — or it is simply not protected.
Credits fail on details, not on substance. A description of goods that does not match the credit, a late presentation, an expired credit, a bill of lading with the wrong consignee, a certificate signed by a party the credit did not name. Under UCP 600 the examining bank has a maximum of five banking days following the day of presentation to decide, and if it refuses it must say so with the discrepancies listed. Most of these are correctable if there is time left in the credit, which is exactly why presentation should not be left to the last day.
Confirmed or unconfirmed
An unconfirmed credit leaves the seller relying on the issuing bank and its jurisdiction. A confirmed credit adds a second bank's independent undertaking, which the seller usually pays for. If a seller asks for confirmation, that is a comment on bank and country risk, not on the buyer.
Documents against payment
Under a documentary collection governed by ICC URC 522, the seller ships and sends the documents through the banking channel with instructions to release them only against payment. It is cheaper than a credit and simpler to arrange. It also carries no bank undertaking at all: if the buyer declines to pay, the seller is left with a cargo sitting at a foreign port. It suits parties with a trading history, not a first transaction.
Part advance against inspection certificate
The common middle ground on container-sized lots is a deposit on contract signature with the balance paid against the independent inspection certificate and the shipping document set. The deposit is real commitment — enough to justify committing production, drums and marking to a specific buyer — while the majority of the money stays tied to independently verified quality, quantity and packing condition. The structure only works if the inspection is genuinely independent: appointed with a scope both sides agreed, with samples sealed and retained, and with the certificate flowing to both parties at the same time.
Why paying in full in advance removes every protection
A buyer who transfers the entire contract value before production has given up, in one step, everything the rest of this page describes. There is no bank obligation, because no bank has undertaken anything. There is no document leverage, because no document has to be produced to release funds. There is no inspection leverage, because the inspection no longer gates a payment; at that point it produces a report and nothing more. There is no lien and no control over the cargo, because the buyer never controlled it. What remains is a claim against a foreign company, enforceable only in a foreign forum, at a cost that on a single container will usually exceed the value in dispute.
That is the honest position, and it does not depend on who the seller is. It is a structural statement about the instrument, not a comment on any counterparty. Full advance is a normal arrangement between parties with a long verified trading history, where commercial relationship substitutes for legal protection. It is not a reasonable arrangement on a first transaction, and no seller who intends to perform should be troubled by a buyer saying so.
Controls that cost nothing
- Verify the counterparty as a legal entity before signing, not after paying.
- Treat any change of bank details arriving by message or email as fraud until proven otherwise, and confirm by voice on a number you already held. Payment diversion is the most common fraud in commodity trade and it targets exactly this moment in the process.
- Keep the document list identical across contract and payment instrument.
- Never let the payment instrument be the first place a new requirement appears.
