What is documentary letter of credit? Types, usage, benefits, and example
Documentary letter of credit is issued by the bank acting on behalf of the importer, guaranteeing payment to an exporter. Learn more about its working in the blog.
Cross-border trade involves numerous risks, particularly when it comes to securing payments between parties who may have never conducted business together before. Documentary letter of credit (DLC) is a crucial financial instrument that helps mitigate such risks while facilitating smooth international transactions. This payment method has become increasingly important in today's interconnected global marketplace, where businesses need reliable ways to conduct international trade with confidence. In this blog, we will explain what a documentary letter of credit (DLC) is, its various types and benefits, and how it is used, along with example.
What is documentary letter of credit (DLC)?
A documentary letter of credit (DLC) is a bank’s written promise to pay the exporter (seller) on behalf of the importer (buyer) once the required documents are submitted. It helps make international trade safer by reducing payment risk. The bank pays the seller as long as the documents show the goods were shipped according to the agreed terms and within the set time.1
Example of documentary letter of credit
Consider a transaction between an Indian textile manufacturer and a US retailer for cotton shirts. The US retailer's bank issues a documentary letter of credit specifying conditions like shipping documents, certificates, and quality requirements. Once the Indian manufacturer ships the goods and presents all required documents to their bank, the payment is processed through the banking channels. This secure payment method ensures the Indian manufacturer receives payment only after fulfilling all specified conditions, while the US retailer is assured of receiving goods as per specifications before payment is released.2
Uses of documentary letter of credit
Documentary letters of credit play a crucial role in global commerce and are commonly used across several high-value and high-risk contexts, including:
International merchandise trade:
Commonly used for import-export transactions involving physical goods, especially in industries like manufacturing, commodities, and bulk goods where substantial monetary value is involved.
Project finance:
Utilized in large infrastructure or development projects where multiple parties, payments, and deliverables are involved across different countries.
Supply chain operations:
Facilitates complex supply chain transactions involving multiple suppliers, intermediaries, and buyers across different geographical locations.
Government contracts:
Used in international government procurement and contracts where regulatory compliance and structured payment mechanisms are mandatory.3
Types of documentary letters of credit
There are different forms of documentary letters of credit in international trade that offer varying levels of security, flexibility, and financing support. Here’s a quick overview:
Irrevocable credit:
A standard and secure form of credit where the issuing bank’s undertaking cannot be changed or cancelled without the beneficiary’s consent, offering strong payment assurance.
Revocable credit:
A rarer form of credit where the issuing bank can modify or cancel at any time without notifying the beneficiary, providing minimal protection in trade.
Confirmed credit:
A credit where a second bank (the confirming bank) adds its own independent payment guarantee, usually requested when the seller is concerned about issuing bank or country risk.
Silent confirmation:
A private arrangement where the advising bank quietly adds a conditional guarantee of payment to the seller, without involving or informing the issuing bank — typically costlier due to higher risk.
Revolving credit:
A reusable credit that automatically replenishes after each drawing, either by time or value, making it ideal for regular, repetitive shipments from the same supplier.
Red clause credit:
A credit that allows the seller to receive an advance before shipping the goods — either unsecured or against warehouse receipts — helping them finance production or procurement.
Green clause credit:
An extended version of the red clause credit that provides pre-shipment advances but requires the goods to be stored under the bank’s control as security.
Transferable credit:
A credit that permits the first beneficiary to transfer part or all of the credit to one or more secondary suppliers, but only if the original credit explicitly states it is transferable.4
How documentary letter of credit works
A documentary letter of credit follows a structured, step-by-step workflow that ensures secure payment and smooth trade execution, typically moving through the following stages:
Initial agreement phase:
The buyer and seller agree on trade terms and decide to use documentary credit as the payment method. They establish key terms and conditions and define required documents.
Letter of credit application:
The importer applies to their bank for the letter of credit, submitting necessary documentation. The bank assesses the importer's creditworthiness and finalizes terms.
Letter of credit issuance:
The issuing bank creates the LC and transmits it to the advising bank, which verifies authenticity and notifies the exporter.
Shipment and documentation:
The exporter reviews LC terms, prepares and ships the goods, and collects all required documents as specified in the LC.
Document presentation:
The exporter presents documents to the advising bank, which checks for compliance before forwarding them to the issuing bank for review.
Payment processing:
Upon verification of compliant documents, the issuing bank processes payment, transferring funds through the advising bank to the exporter.5
Benefits of documentary letter of credit
Using a documentary letter of credit offers several strategic advantages for businesses engaged in cross-border trade, including:
Payment security:
Exporters receive guaranteed payment from a creditworthy bank, eliminating the risk of payment default and ensuring financial protection regardless of the buyer's financial situation.
Risk mitigation:
Both parties gain protection through bank intermediation, reducing concerns about unfamiliar trading partners and new market entry. The bank's involvement provides a trusted verification mechanism for documentation and compliance.
Working capital management:
Businesses can leverage documentary credits to access better financing options and maintain healthy cash flow. Banks often provide preferential financing terms when transactions are backed by LCs.
Global market access:
Enables businesses to confidently enter new international markets and establish trading relationships with unknown partners, supported by a standardized, globally recognized payment system.
Regulatory compliance:
Helps businesses meet international trade regulations and foreign exchange requirements, as banks ensure all transactions comply with local and international laws.6
Parties involved in a DLC agreement
A documentary letter of credit involves several key participants, each playing a specific role in ensuring a secure and compliant trade transaction:
● Applicant: The party on whose request the credit is issued (the buyer or importer).
● Issuing bank: The bank that issues a credit at the request of an applicant or on its own behalf.
● Advising bank: The bank that advises the credit at the request of the issuing bank.
● Confirming bank: The bank that adds its confirmation to a credit, in addition to that of the issuing bank, to honour or negotiate a complying presentation.
● Nominated bank: The bank with which the credit is available or any bank in the case it is available with any bank.
● Beneficiary: The party in whose favour the credit is issued and normally the provider of the goods, services or performance (the seller or exporter).7
Conclusion
Documentary letters of credit remain a cornerstone of international trade finance, providing security and facilitating global commerce. While the process may seem complex, understanding its mechanisms and benefits can help businesses expand their global reach with confidence.
