# Letter of credit China importer guide: the complete 2026 walkthrough
Of all the ways to pay a Chinese supplier, the letter of credit is the most formal, the most paper-heavy, and the most misunderstood. Many importers have heard that a letter of credit China importer guide would recommend it for large orders, but few know what actually happens between the application and the payment. This guide walks through the whole instrument: what it is, the types you will encounter, how the process runs step by step, what it costs, and where deals go wrong. Treat this letter of credit China importer guide as the orientation you read before your first application, not as a substitute for your bank's advice.
The letter of credit exists for one reason. In international trade, the buyer and seller do not trust each other yet. The buyer will not pay before shipment, the seller will not ship before payment. The letter of credit breaks the deadlock by putting a bank's promise in the middle: pay the seller when the shipping documents prove the goods went out as agreed. Everything else in this letter of credit China importer guide is detail around that one promise.
Letter of credit China importer guide: what it actually is
A letter of credit is a written undertaking from a bank, issued at your request, to pay the supplier a set amount provided the supplier presents documents that match the credit's terms exactly. The key word is documents. The bank does not inspect your goods. It inspects paperwork: the bill of lading, the commercial invoice, the packing list, the certificate of origin, and whatever else the credit requires.
This surprises first-time users. You can receive goods that are wrong in every way, and if the documents are perfect, the bank still pays. The letter of credit protects against shipment failure and document fraud, not against quality problems. Quality is handled by inspections, which run alongside the credit, not inside it.
The main parties are you (the applicant), your bank (the issuing bank), the supplier (the beneficiary), and usually a bank in China (the advising or confirming bank) that handles the documents on the supplier's side. Each party has defined duties, and the rules most credits follow are a published set of international banking practices. Your bank will know them; you mainly need to know they exist and that they are strict.
The types you will actually encounter
Letters of credit come in several flavors, and the type changes who bears which risk.
An irrevocable letter of credit cannot be changed or cancelled without everyone's agreement. This is the standard in modern trade. If anyone offers you a revocable credit, decline it; it can be cancelled while your goods are on the water. That single warning justifies reading a letter of credit China importer guide before you sign anything.
A sight letter of credit pays the supplier when compliant documents are presented, usually within days. A usance (or deferred) letter of credit pays after a set period, such as 90 days after the bill of lading date. Usance credits give you time to receive and sell the goods before the money leaves, which is why suppliers charge for the privilege, either in the price or through a discounting arrangement.
An unconfirmed letter of credit carries only your bank's promise. The Chinese bank advises it to the supplier but adds no commitment of its own. A confirmed letter of credit adds the Chinese bank's own payment promise on top, and this letter of credit China importer guide treats confirmation as worth the money whenever the supplier doubts your country's banks.
Transferable credits let a trading company pass the credit to the actual factory. Back-to-back credits achieve something similar with two separate instruments. You will meet these when your supplier is a middleman rather than the manufacturer. Most importers only ever use irrevocable sight or usance credits, but a complete letter of credit China importer guide should name the rest so you recognize them when a supplier proposes one.
The process, step by step
Here is how a letter of credit China importer guide should describe the actual sequence, because the order of operations is where beginners get lost.
First, you and the supplier agree the sale contract, including the term "payment by irrevocable letter of credit" and the details that will go into the credit: amount, shipment date, required documents, and ports.
Second, you apply to your bank. The bank checks your credit line, since it is taking on a payment obligation, and issues the credit. This means sending a structured message to the advising bank in China with all the terms.
Third, the advising bank notifies the supplier. The supplier reads the credit carefully. This is a critical moment: if any term is impossible, wrong product description, shipment date too tight, a document they cannot obtain, the supplier must ask for an amendment now, before shipping.
Fourth, the supplier ships the goods and gathers the documents. The bill of lading is the most important; it is the title to the goods. The supplier presents the full document set to their bank within the presentation period stated in the credit.
Fifth, the banks examine the documents. They check each document against the credit terms, letter by letter. If everything complies, the issuing bank pays (or accepts the deferred obligation for a usance credit), and the documents come to you. You need the bill of lading to claim the goods from the shipping line, which is why the document flow matters as much as the money flow. Follow this sequence and the letter of credit China importer guide process stays boring, which is exactly what you want.
What it costs
Letters of credit are not cheap, and the costs fall on both sides by custom. As the importer you typically pay your bank's issuance fee, which is usually a percentage of the credit amount with a minimum charge, plus messaging and amendment fees. Amendments are where costs creep: every change to the credit after issuance triggers a fee, so getting the terms right the first time saves real money.
The supplier pays their bank's advising and negotiation fees, and pays for confirmation if they want it. On a usance credit, someone pays for the time value of the deferred payment, either through a higher price or a separate discounting charge.
For small orders these fixed costs are punishing. A credit with minimum fees can add several percentage points to a modest order. The instrument makes economic sense from roughly the mid five figures upward in order value, though the exact threshold depends on your bank's fee schedule. Get the schedule in writing before you promise a supplier payment by letter of credit. These minimums are why every letter of credit China importer guide warns against using credits for small orders.
Discrepancies: where most credits stumble
Here is the statistic-free truth about letters of credit: a large share of first presentations contain discrepancies, meaning differences between the documents and the credit terms. Banks reject or flag these, payment gets delayed, and everyone pays extra fees while it gets sorted.
The classic discrepancies are mundane. The invoice shows a slightly different goods description than the credit. The bill of lading is dated after the latest shipment date. A required certificate is missing a stamp. The packing list totals do not match the invoice. None of these mean the goods are wrong. All of them mean the documents do not match, and the bank's job is to match documents, not to be reasonable about goods.
Prevention beats cure. Before the supplier ships, have them send you draft documents for review against the credit terms. Many freight forwarders will do this check as part of their service. Catching a wrong date on a draft bill of lading costs nothing. Catching it after presentation costs fees, delay, and sometimes a stranded container. Draft review is the single highest-value habit in this letter of credit China importer guide.
When discrepancies happen anyway, you have choices: accept them and authorize payment despite the mismatch, ask the supplier to correct and re-present, or negotiate. Most discrepancies on genuine shipments get waived by the buyer, because the commercial relationship matters more than documentary perfection. Waiving is routine, but this letter of credit China importer guide notes the right to refuse is genuine negotiating power in real disputes. But you should know you have the right to refuse, which gives you negotiating power if the goods themselves are also in doubt.
When a letter of credit is the right choice
Use a letter of credit when the order is large enough to justify the cost, the supplier is new or the relationship is thin, and the supplier's country or banking situation makes open-account payment uncomfortable. It is also the right tool when your own cash flow needs the discipline of documents: the money moves only when shipment is proven.
Do not use one for small repeat orders with a trusted supplier. The fees and paperwork will annoy both sides and add nothing. Do not use one as a quality control tool; it is not one. Pair it with a pre-shipment inspection, which checks the goods while the credit checks the paper.
Also consider the supplier's perspective. Many Chinese factories dislike letters of credit because of the discrepancy risk and the slower payment. If you insist on a credit with a supplier who preferred a wire transfer, expect the price to reflect their hassle. Sometimes the right commercial answer is a simpler instrument plus an inspection, not the heaviest instrument available. Knowing when not to use one is as important as anything else in this letter of credit China importer guide.
Practical tips from experienced users
Keep the credit terms as simple as the deal allows. Every extra required document is another chance for a discrepancy. If you do not need a certificate of origin for your customs process, do not put it in the credit.
Set the shipment date and expiry with slack. Production runs late; that is the nature of manufacturing. A credit that expires the day after the planned shipment date will need an amendment, with fees, the moment anything slips.
Choose the advising bank with the supplier, not unilaterally. The supplier's bank relationship affects how smoothly documents get handled on their side. Ask the supplier which bank they prefer and use it if your bank can.
And read the credit yourself when the draft comes from your bank. Banks copy the sales contract into credit language, and errors creep in. The applicant, you, is responsible for the terms being right. An hour of careful reading at issuance saves weeks of amendments later. That hour of reading is the cheapest insurance this letter of credit China importer guide can recommend.
Conclusion
A letter of credit China importer guide can only take you so far on paper; the instrument rewards users who respect what it is and do not ask it to be what it is not. It is a payment guarantee tied to documents, excellent at ensuring shipment happens and payment follows, useless at ensuring quality. Choose the right type for the deal, keep terms simple, review drafts before shipment, and pair the credit with an independent inspection. Do that, and the most formal payment method in China trade becomes a routine one.
FAQ
**How much does a letter of credit cost?** Your bank typically charges an issuance fee as a percentage of the credit amount plus a minimum charge, with extra fees for amendments and messaging. The supplier pays advising and negotiation fees on their side. Get your bank's full fee schedule in writing before committing, since minimum fees make credits expensive for small orders.
**How long does it take to open a letter of credit?** With an established credit line, issuance usually takes a few working days after you submit the application. The first credit with a new bank takes longer because the bank must approve your credit facility first, which can take weeks.
**Does a letter of credit guarantee the quality of my goods?** No. The bank pays against documents, not against goods. A letter of credit protects you against non-shipment and document problems. Quality protection comes from inspections, which you should arrange separately. That limitation is worth repeating because this letter of credit China importer guide finds it is the most common misunderstanding among first-time users.
**What happens if the documents have discrepancies?** The bank will flag them and may refuse to pay until they are fixed or you waive the discrepancies. Most commonly the buyer waives minor mismatches on genuine shipments, but you have the right to refuse, and corrections mean extra fees and delays.
**Sight or usance: which letter of credit should I choose?** Sight credits pay the supplier on compliant presentation, which suppliers prefer. Usance credits defer payment, often 60 to 120 days, which helps your cash flow but costs more. Choose based on who needs the cash-flow benefit and what the supplier will accept. Your bank can model both; this letter of credit China importer guide suggests asking for the all-in cost comparison in writing.
**Can a letter of credit be cancelled after it is issued?** An irrevocable letter of credit, the standard type, cannot be cancelled or amended without the agreement of all parties. This is what gives the supplier confidence to manufacture and ship. That irrevocability is the feature this letter of credit China importer guide keeps returning to.
