Letter of Credit in Global Trade

In today’s globalized business environment, the Letter of Credit (L/C), as an internationally recognized payment instrument, provides both buyers and sellers with secure and standardized settlement assurance by incorporating bank credit. It serves as a reliable bridge facilitating international trade.

This article offers a comprehensive overview of Letters of Credit, with a particular focus on Sight Letters of Credit.

I. Basic Concepts and Main Classifications of Letters of Credit

a. Definition of a Letter of Credit (L/C):

A Letter of Credit is a conditional payment undertaking issued by the issuing bank (the buyer’s bank) at the request of the buyer (importer) in favor of the seller (exporter). In international trade, an L/C essentially represents a mechanism whereby bank credit replaces commercial credit, thereby addressing the fundamental issue of mutual distrust between the buyer and the seller.

b. Main Classifications of L/C

Letters of Credit are primarily classified into two main categories: Sight Letters of Credit and Usance (or Deferred Payment) Letters of Credit.

Types of LCPayment TimeProportion

II.Basic Concept and Advantages of a Sight Letter of Credit

a. Basic Concept of Sight L/C

A Sight Letter of Credit (L/C at sight) is a payment instrument under which the issuing bank or paying bank immediately fulfills its payment obligation upon receipt of documents and a draft that comply with the terms of the credit. Its core feature is “payment upon presentation of compliant documents”.

III. Letter of Credit Process

a. Contract Agreement

The buyer and seller clearly agree in the trade contract to use a Sight Documentary Letter of Credit as the payment method, and specify key details such as documentary requirements and shipment deadlines.

b. Application for Letter of Credit

The importer completes a Letter of Credit Application and submits supporting documents, including the trade contract, import license, and company qualification certificates, to the issuing bank. A deposit (ranging from 0% to 30% of the L/C amount) is also paid, depending on the importer’s credit standing.

c. Issuance and Transmission of the L/C

The issuing bank sends the L/C to the advising bank via the SWIFT system (in MT700 format). The advising bank verifies the apparent authenticity of the L/C (e.g., through cipher codes or signature stamps), collects an advising fee (approximately CNY 200), and then forwards the L/C to the beneficiary.

d. Beneficiary’s Review

The exporter carefully reviews the L/C for key terms, such as the expiry date and shipment deadline, and verifies whether the documentary requirements are feasible (e.g., type of bill of lading, certification documents). If discrepancies are found, the beneficiary must request amendments immediately, which require the consent of all relevant parties.

e. Shipment and Document Preparation

The exporter arranges shipment in accordance with the requirements of the Letter of Credit and prepares the full set of required documents, which typically include: Bill of Lading (B/L)、Commercial Invoice、Packing List、Certificate of Origin (CO)、Inspection Certificate (e.g., SGS Report), if required

f. Submission of Documents to the Bank

The exporter submits the documents to the presenting bank or nominated bank, preferably a bank with which the beneficiary has an established relationship.

g. Bank Examination of Documents and Payment

The issuing bank or nominated bank examines the documents within 5 business days based on the principle of “apparent compliance” (reviewing documents only, without inspecting the goods themselves). Once the documents are confirmed to be in compliance, the issuing bank must make payment promptly.

h. Reimbursement and Release of Documents

The issuing bank reimburses the paying or negotiating bank. The importer then makes payment to redeem the documents (if the full deposit was not paid at the time of L/C issuance).

Note In the event of an unjustified refusal of payment by the issuing bank, the beneficiary may seek arbitration through the International Chamber of Commerce in accordance with UCP 600.

IV. Key Risks in Letter of Credit Operations and Mitigation Strategies

Types of RisksRisk Avoidance Strategies
Documentary Discrepancies: Examples include incorrect consignee name on the bill of lading, invoice amount not matching the Letter of Credit, and other inconsistencies in required documents.Conduct Strict L/C Examination: Upon receipt of the Letter of Credit, carefully review all terms line by line, with particular attention to shipping conditions, documentary requirements, and the validity period.
Soft Clause Traps: Unreasonable conditions embedded in the L/C (e.g., requiring buyer’s signature for document acceptance) that make it difficult or impossible for the beneficiary to fulfill the terms.Opt for a Confirmed L/C: If the creditworthiness of the issuing bank in the buyer’s country is in doubt, request a confirmed Letter of Credit to obtain an additional guarantee from a reputable bank.
Exchange Rate Fluctuations: Currency market volatility may impact profitability, especially when the local currency depreciates or appreciates significantly against the settlement currencyUtilize Financial Instruments: Use forward foreign exchange contracts to lock in exchange rates and hedge against currency fluctuation risks.

V. Conclusion

The Letter of Credit, especially the Sight Letter of Credit, is an indispensable risk management tool in tire trade. Through standardized procedures and effective risk control, businesses can achieve secure and efficient cross-border transactions. With the advancement of digital technologies, Letters of Credit are expected to further streamline processes and support the tire industry in maintaining stable growth in the global market.
