LC vs T/T: Which Payment Method Is Safer for Importers?
When buying from an overseas supplier, the payment method can change the risk of the transaction just as much as the product price. Two of the most common options are LC, Letter of Credit, and T/T, Telegraphic Transfer, which in practice usually means a bank wire transfer.
Neither method is automatically safe or unsafe. The real question is when the buyer must release money, what conditions must be met, and what protection exists if the supplier does not perform as expected.

What Is T/T Payment?
T/T is a direct bank transfer from the buyer to the supplier. It is simple, fast and widely used in international trade. The important part is not the transfer technology itself. It is the agreed payment schedule.
A supplier might request 100% before production, 30% as a deposit and 70% before shipment, 30% deposit and 70% after seeing shipping documents, or payment after delivery. These are all T/T transactions, but the buyer's risk is very different in each case.
If an importer sends 100% before production, the supplier holds almost all of the commercial leverage. If the buyer pays a smaller deposit and keeps a meaningful balance unpaid until agreed milestones are completed, the buyer retains more control.
What Is a Letter of Credit?
A Letter of Credit is a bank undertaking to pay the seller when the seller presents documents that comply with the terms of the LC. The buyer and seller agree the documentary conditions, and the issuing bank handles payment according to those conditions.
An LC can require documents such as a commercial invoice, packing list, bill of lading, certificate of origin, inspection certificate or other shipment documents. This means the supplier normally cannot obtain payment merely by asking for it. The required documents must be presented in the form specified by the credit.
This documentary structure can reduce some payment risk, but it is important to understand the limitation: banks examine documents, not the actual goods. A compliant document set does not guarantee that the product quality, dimensions, materials or workmanship are correct.
That is why documentary requirements should be aligned carefully with the commercial contract. Exporters preparing LC shipments also benefit from a disciplined document process such as the one described in Export Documentation Checklist: Invoices, Packing Lists and Shipping Documents.
Which Is Safer for the Importer?
For a new supplier, a properly structured LC can give an importer more control than paying a large amount by T/T before shipment. The supplier must satisfy agreed documentary conditions before the bank releases payment under the credit.
However, an LC is not automatically safer in every transaction. If the LC conditions are weak, vague or easy to satisfy without proving the important commercial requirements, the buyer may still face substantial risk. An LC also does not replace supplier verification, product inspection, clear specifications or a strong purchase contract.
T/T can also be perfectly reasonable when the buyer already trusts the supplier, the order value is manageable, the payment schedule is balanced, and the buyer has other controls such as samples, inspections, production updates and shipping-document checks.
The Biggest Risk With T/T Is Payment Timing
The phrase "T/T payment" does not tell you enough to judge whether a deal is safe. The key detail is the timing.
100% T/T in advance gives the supplier maximum protection and gives the buyer very little leverage after payment. This may be acceptable for small sample orders, low-value purchases or highly trusted suppliers, but it can be risky for a first large order.
Deposit plus balance before shipment is common because the deposit helps the supplier finance production while the buyer keeps part of the payment outstanding. The risk depends on the deposit size and what evidence the buyer receives before paying the balance.
Balance against shipping documents can improve the buyer's position, but the buyer should still understand exactly which documents are required and whether those documents prove the things that matter commercially.
Payment after shipment or after delivery usually favors the buyer more strongly, but new suppliers may be unwilling to offer those terms without an established relationship, credit insurance or another form of security.
Where an LC Gives the Buyer More Control
An LC is most useful when the buyer wants payment linked to specific documentary evidence. For example, the credit can require shipment by a certain date, transport documents showing the agreed destination, an inspection certificate, a certificate of origin, or other documents relevant to the transaction.
This can be especially useful for higher-value orders, new supplier relationships, transactions where both parties want bank involvement, or purchases where the seller is unwilling to ship on open-account terms.
It also creates a formal structure around deadlines and documents. That discipline can help both sides understand exactly what must happen before payment.
Where an LC Can Create Problems
Letters of credit are more complex than simple bank transfers. Banks charge fees, documentation must be prepared carefully, and discrepancies can delay payment or require amendments.
If the purchase order says one thing, the LC says another, and the shipping documents use slightly different wording, the transaction can become unnecessarily difficult. The buyer should therefore avoid filling an LC with conditions that are hard to document objectively.
An LC can also create a false sense of security. For example, an invoice and clean bill of lading may prove that documents were presented correctly, but they do not prove that every unit inside the shipment meets the buyer's technical specification.
LC vs T/T for a First Order
For a first substantial order from an unfamiliar supplier, the buyer should avoid choosing a payment method based only on what is normal in the supplier's country or industry. The risk should be considered together with order value, supplier history, product complexity, lead time, inspection options and the buyer's ability to recover funds if something goes wrong.
If the supplier requests a large T/T deposit, the buyer can negotiate a smaller deposit, staged payments, inspection before the final balance, or another milestone that keeps some leverage until production is completed.
If the order value justifies the additional banking cost and documentary work, an LC may provide a stronger framework. But the LC conditions must be drafted carefully enough to protect the buyer without making compliance impractical.
Do Not Ignore Supplier Verification
No payment method should replace basic supplier due diligence. Before sending a deposit or opening an LC, verify the supplier's legal identity, bank account details, business address, production capability and commercial track record where possible.
Bank-account fraud is also a real operational risk in international trade. If a supplier suddenly asks you to send money to a new bank account, confirm the change through a trusted communication channel before transferring funds.
The same principle applies when comparing supplier quotations. Price, Incoterm, payment schedule, lead time, MOQ and documentation requirements should be evaluated together rather than separately.

Which Payment Method Should You Choose?
Choose T/T when the supplier relationship is established, the commercial risk is acceptable, the payment schedule leaves the buyer reasonable leverage, and the simplicity and lower transaction cost are important.
Consider an LC when the order value is substantial, the supplier relationship is new, both parties want bank-backed documentary payment conditions, or the buyer needs stronger control over the documents required before payment.
For many importers, the safest answer is not simply "LC is better" or "T/T is better." A well-negotiated T/T structure can be safer than a poorly drafted LC, while a carefully structured LC can provide much better protection than sending most of the order value in advance.
The payment method should match the size of the transaction, the level of trust between buyer and supplier, and the buyer's ability to verify production and shipment before releasing funds.
