Letters of Credit for Electronics Importers: A Practical Guide

A letter of credit (LC) is the most bank-intensive payment method in international trade. It’s also the one that genuinely protects both sides of a large transaction. If you’re placing orders in the $30,000 to $500,000 range with a Chinese supplier you don’t fully trust yet, an LC is worth understanding.

Most importers never use one. Wire transfer (T/T) is faster and simpler for small orders. Trade Assurance works well on Alibaba. But once your order size climbs and the stakes get real, the LC stops being overkill and starts being smart.

What a Letter of Credit Actually Is

An LC is a payment guarantee issued by your bank. It tells your Chinese supplier: “If you ship the goods and present the right documents, my bank will pay you.” Your supplier doesn’t have to trust you anymore. They trust your bank.

Here’s the basic sequence:

You apply to your bank (called the issuing bank) for an LC. Your bank opens the LC and sends it to your supplier’s bank in China (called the advising bank or confirming bank). Your supplier sees the LC, confirms the terms, and ships the goods. After shipping, your supplier presents a specific set of documents to their bank. If those documents match the LC terms exactly, the bank pays. Your bank then debits your account or draws on your credit line.

The key word is “exactly.” We’ll come back to that.

Types of Letters of Credit

Sight LC

Payment happens when the documents are presented and verified. Your supplier presents the bill of lading, invoice, and other required documents, the banks check everything, and the funds transfer. This is the most common LC type for electronics.

Time LC (also called a Usance LC)

Payment happens a set number of days after document presentation. Common terms are 30, 60, or 90 days after sight. This is effectively supplier financing. Your supplier ships the goods and gets paid 60 days later. It gives you time to receive and sell inventory before the payment hits. Chinese suppliers often charge a higher price for usance terms, since they’re extending credit to you.

Revolving LC

Built for repeat orders on a regular schedule. Instead of opening a new LC for every shipment, you open one LC that “revolves” back to its original amount after each drawing. If you’re importing $50,000 worth of LED drivers every month from the same factory, a revolving LC cuts down on paperwork and bank fees.

Standby LC

This one works more like a backup guarantee than a primary payment method. Your supplier expects to be paid by T/T. The standby LC is only drawn if you fail to pay. Think of it as a performance bond. Some long-term supplier relationships use standby LCs to give the supplier security without the full document burden of a commercial LC.

How LCs Protect You Compared to Wire Transfer

With a standard T/T wire, you’re trusting the supplier. If you pay 30% upfront and 70% before shipping, you’ve sent money into a foreign bank account with limited recourse if things go wrong.

An LC flips this. The bank only releases funds when the supplier presents documents proving they shipped what you ordered. Typically those documents include:

A commercial invoice matching the LC amount and description. A full set of original ocean bills of lading showing the goods were shipped. A packing list matching the invoice. A certificate of origin (usually Form E for ASEAN tariff benefits or a standard commercial certificate). An inspection certificate if your LC requires pre-shipment inspection.

If the supplier ships the wrong product, the wrong quantity, or ships late (past the LC expiry date), the documents won’t match the LC terms. The bank won’t pay. That’s your protection.

Your supplier gets protection too. Once an LC is issued, you can’t just cancel payment like you might dispute a credit card charge. The bank is contractually obligated to pay if the documents are clean. Your supplier can ship with confidence.

When LCs Make Sense vs. Simpler Options

LCs are not the right tool for every order. Here’s where the lines are:

Under $10,000: Don’t bother. Trade Assurance on Alibaba handles this well. T/T with a 30% deposit is fine for verified suppliers. The LC setup time and fees aren’t worth it.

$10,000 to $30,000: It depends on how well you know the supplier. First order with a new factory? An LC makes sense even at this level. Tenth order with a factory you’ve visited? T/T is fine.

$30,000 to $500,000: This is the natural home for LCs. The bank fees become a small percentage of the order value. The protection is real. Your supplier will expect you to know what an LC is at this order size.

Over $500,000: LCs are standard. Many large Chinese factories won’t accept other payment terms at this scale. Your freight forwarder and customs broker will expect LC documentation.

The Cost of Opening a Letter of Credit

Banks don’t issue LCs for free. Budget 1% to 2% of the LC value as a rough total cost estimate. Here’s where that money goes:

Issuance fee: Charged by your bank to open the LC. Typically 0.25% to 1.5% of the LC value, with a minimum fee (often $150 to $300). A $100,000 LC might cost $400 to $800 to issue.

Confirmation fee: If you ask the Chinese bank to “confirm” the LC (meaning they also guarantee payment), the Chinese bank charges a confirmation fee. This adds supplier-side confidence and typically adds 0.1% to 0.5% of the LC value.

Cable/SWIFT fees: The banks charge for the international messaging. Usually $50 to $150. A minor cost but it adds up.

Amendment fees: If you need to change any LC term after issuance (new shipment date, different quantity, address correction), both banks charge amendment fees. Typically $50 to $200 per amendment, per bank. Avoid amendments. Write the LC right the first time.

Discrepancy fees: If your supplier presents documents that don’t exactly match the LC terms, the banks charge a discrepancy fee (typically $75 to $200) to process the waiver request. More on this below.

Opening an LC: What Your Bank Needs

You don’t walk into a bank and open an LC the same day. Here’s what the process looks like:

First, you need an established relationship with a bank that handles international trade finance. Many small regional banks don’t offer LCs at all. Major US banks (Citibank, JPMorgan Chase, Bank of America, Wells Fargo), trade finance specialists, and some credit unions with international departments do.

Your bank will ask for your business financial statements, tax returns, and an assessment of your creditworthiness. An LC is a bank commitment to pay, so the bank is taking on your risk. If your company is young or thinly capitalized, some banks will require you to deposit the full LC amount as cash collateral. Others will extend it as a credit line.

You’ll fill out an LC application that includes: the beneficiary name and address (your Chinese supplier), the LC amount and currency, the expiry date and place, required documents, the latest shipment date, port of loading and discharge, Incoterms, and a description of the goods.

Allow 5 to 10 business days for your first LC. Repeat LCs with the same supplier on the same bank are faster, sometimes 2 to 3 days.

What the LC Documents Must Say

The documents your supplier presents to get paid must match the LC terms character by character. This sounds extreme, but that’s how it works. International LC law (governed by ICC’s UCP 600 rules) requires strict compliance.

Your commercial invoice must show the exact beneficiary name, LC number, and goods description as written in the LC. The bill of lading must show the exact port of loading and discharge. The packing list must match the invoice quantities. The certificate of origin must be from the correct issuing body named in the LC.

One wrong digit in an LC number on the invoice. One field filled in differently than expected. The country of origin listed as “China” on the invoice but “P.R. China” on the certificate of origin. Any of these create a discrepancy.

Discrepancies: The Thing That Kills LC Payments

Discrepancies are the biggest practical frustration with LCs. Studies by the International Chamber of Commerce have found that over 50% of first document presentations contain at least one discrepancy.

When the presenting bank finds a discrepancy, it notifies your supplier. Your supplier has three options. They can correct and re-present documents (if time allows before the LC expires). They can ask you to waive the discrepancy. Or they can ask the banks to accept discrepant documents under reserve, meaning they get paid but refund the money if you refuse to waive.

If you waive a discrepancy, both banks charge a discrepancy fee. More importantly, if you waive the discrepancy, you’ve accepted the documents. Your bank pays. Even if you later find the goods are wrong, you’ve lost your LC protection for that shipment.

The solution is to write clean LC terms upfront and share the draft LC with your supplier before you submit it to the bank. Ask them to flag anything they can’t comply with. Fix it in the draft, not after issuance.

Writing LC Terms That Don’t Trap You

Bad LC terms create two problems. They’re impossible for your supplier to comply with exactly. Or they’re so loose they don’t protect you.

Here are practical rules for electronics importers:

Write the goods description in plain, verifiable language. “2,000 units of 65W USB-C GaN chargers, model XY-65W, as per purchase order #2024-071” is better than a long technical specification that might not match the supplier’s invoice format exactly.

Don’t require documents that are hard to get. If you require an inspection certificate from a specific inspection company, confirm your inspection company will issue exactly that document before you put it in the LC.

Set the expiry date with enough margin. Your supplier needs time to ship, collect documents, and present them to the bank. Allow at least 21 days after the latest shipment date for document presentation, and at least 15 days between signing the LC and the latest shipment date.

Allow partial shipments if your order might arrive in multiple containers. If you don’t, and the supplier ships 95% of your order in one container and the remaining 5% separately, you have a discrepancy.

Use standard Incoterms (CIF, FOB, CFR) and write them exactly as ICC defines them. “FOB Shanghai” not “FOB at port.”

The Electronics Importer’s Practical Recommendation

For first orders over $30,000 with a new supplier, open a sight LC. Yes, it takes more time than a wire transfer. Yes, it costs 1% to 2% of the order value. But it forces both sides to be precise, protects your payment, and gives your supplier payment certainty.

For ongoing supplier relationships where you’ve done 3 to 5 orders without problems, T/T becomes reasonable again. You’ve built the track record. The LC overhead stops being worth it.

The one situation where an LC is always worth it regardless of order size: a first-time order with a supplier you found outside of Alibaba or a major platform, where you have no third-party verification of who they are. A supplier who refuses to accept LC terms on a large first order is a supplier worth being suspicious of.

Frequently Asked Questions

What is a letter of credit in electronics importing? A letter of credit (LC) is a payment guarantee issued by your bank. It tells your Chinese supplier that your bank will pay them if they ship the goods and present the correct shipping documents. It protects you from paying for goods that were never shipped, and protects your supplier from a buyer who refuses to pay.

How much does a letter of credit cost? Budget 1% to 2% of the LC value for total bank fees. The main costs are the issuance fee (0.25% to 1.5%), confirmation fees if you ask the Chinese bank to confirm the LC, SWIFT cable fees, and amendment fees if you need to change any terms after issuance.

When should I use a letter of credit instead of Trade Assurance? Trade Assurance on Alibaba works well for orders under $30,000 with verified Alibaba suppliers. Use an LC for orders over $30,000, for first orders with suppliers you found outside major platforms, or when your supplier requires LC terms for large orders.

What happens if there’s a discrepancy in the LC documents? A discrepancy means the documents your supplier presented don’t exactly match the LC terms. The bank won’t pay until the discrepancy is resolved. Your supplier can correct documents, ask you to waive the discrepancy, or request payment under reserve. Both banks charge a discrepancy fee, typically $75 to $200. If you waive the discrepancy, you lose your document-level protection for that shipment.

How long does it take to open a letter of credit? Allow 5 to 10 business days for your first LC with a bank. Repeat LCs with the same bank can be processed in 2 to 3 business days. You need an established relationship with a bank that offers trade finance services. Many small regional banks don’t offer LCs at all.

Can I get a letter of credit from any bank? No. You need a bank with a trade finance department. Major US banks like Citibank, JPMorgan Chase, Bank of America, and Wells Fargo offer LCs. Some regional banks with international business clients do too. Start asking your bank early, before you need one, because they’ll assess your creditworthiness before approving LC applications.

Can my Chinese supplier refuse to accept LC terms? Yes. Some small factories, especially those selling through Alibaba’s standard storefronts, don’t have the banking infrastructure to handle LCs. They prefer T/T because it’s simpler. If a supplier can’t or won’t work with an LC on a large order, that tells you something about their size and sophistication. Either find a supplier who can, or do more due diligence before agreeing to T/T terms.

Is a letter of credit the same as a bank guarantee? They’re related but different. An LC is a payment mechanism tied to specific shipping documents. A bank guarantee is a broader promise that the bank will cover losses if a party fails to perform. In electronics importing, LCs are the relevant tool. Bank guarantees show up more in construction contracts and long-term supply agreements.

What’s UCP 600 and why does it matter? UCP 600 is the Uniform Customs and Practice for Documentary Credits, published by the International Chamber of Commerce. It’s the rulebook that governs how LCs work worldwide. When your LC states “subject to UCP 600” in its terms, both banks and both parties agree to follow these rules for document compliance, discrepancy handling, and payment timelines. Your LC should always reference UCP 600.

Do I need a freight forwarder before I can open an LC? You don’t need a freight forwarder to open an LC, but you’ll need one before your goods ship. The bill of lading that your freight forwarder or carrier issues is usually the most important document in the LC. Talk to your freight forwarder before you finalize the LC terms, especially around port names, Incoterms, and whether you need an original negotiable bill of lading or a telex release.
