Letter of Credit for China Imports: How L/C Protects Both Buyer and Supplier

For a large first order with an unfamiliar Chinese supplier, a Letter of Credit is the payment instrument that lets both sides sleep. The buyer keeps control of the cash until the supplier proves the goods have shipped, and the supplier can borrow against the L/C to fund production. This guide explains how an L/C actually works, the documents that drive it, the main types buyers choose and the situations where L/C is preferable to a telegraphic transfer deposit.

How a Letter of Credit works

An L/C is a written promise by the buyer's bank to pay the supplier a fixed amount, provided the supplier presents a defined set of documents within a fixed deadline. The bank substitutes its own credit for the buyer's, so the supplier is no longer relying on the buyer's promise alone. Once the L/C is issued, the buyer's bank becomes the obligor. The supplier ships the goods, collects the documents listed in the L/C — typically a bill of lading, commercial invoice, packing list and certificate of origin — and presents them to its own bank, which checks them against the L/C terms and forwards them for payment. If every document matches, the bank releases the funds; if there is a discrepancy, the buyer is asked to waive it or the payment is held.

Document requirements and why they matter

The strength of an L/C lives in its documents, because banks deal in documents, not in goods. A typical building-material L/C calls for a full set of clean on-board ocean bills of lading consigned to the issuing bank, a signed commercial invoice, a detailed packing list, a certificate of origin (often Form A or a free-trade-agreement certificate), a pre-shipment inspection certificate if third-party QC was agreed, and sometimes a beneficiary's certificate confirming that shipment advice was sent to the buyer. Each document must match the L/C word for word in dates, quantities, weights and consignee details. A single missing initial or a port name spelt differently can trigger a discrepancy, which is why the supplier should always review the draft L/C before the bank issues it.

The main L/C types buyers actually use

Almost every building-material L/C is irrevocable, meaning it cannot be changed or cancelled without the agreement of all parties. The other common variations stack on top. An L/C at sight pays the supplier the moment compliant documents are presented, which suppliers prefer because cash flow is fast. A usance, or deferred, L/C pays at a fixed period after presentation — for example 60 days — giving the buyer time to sell the goods before paying. A confirmed L/C adds a second bank, usually in the supplier's country, that takes on the payment obligation, removing the risk that the issuing bank or its country defaults; confirmation is worth the extra fee when the buyer's bank is in a higher-risk jurisdiction. For first-time relationships, the safest combination is an irrevocable, confirmed L/C at sight.

L/C versus T/T deposit, and a sample clause

Most Chinese suppliers accept a 30 percent T/T deposit with 70 percent against the bill of lading copy, and for repeat orders this is faster and cheaper than an L/C. L/C becomes worthwhile when the order is large (typically above 50,000 US dollars), when the buyer wants to conserve cash until shipment, or when the supplier needs the L/C to raise production finance from its own bank. Bank fees for an L/C are usually 0.1 to 0.25 percent of the value per quarter plus fixed advising and amendment charges, so very small orders lose money to fees. A workable clause for a building-material order reads: "Payment by irrevocable Letter of Credit at sight, confirmed by a first-class international bank, for 100 percent of the invoice value, available against presentation of full set clean on board marine bills of lading, commercial invoice, packing list and certificate of origin, all documents issued within the validity of the credit."

Used correctly, a Letter of Credit aligns the interests of buyer, supplier and bank: the supplier gets a bank-backed promise that unlocks production finance, and the buyer gets a guarantee that money only leaves the account when the right paperwork proves the right goods have shipped. The cost is real — in fees, in document discipline and in lead time — but for a large first order with a new partner, that cost is cheap insurance against the alternative of paying in full and hoping for the best.
