Introduction
Letters of credit are among the most important instruments used in international trade finance in Turkey. Turkish exporters, importers, banks, logistics companies, commodity traders, manufacturers and foreign commercial partners frequently rely on letters of credit to reduce payment risk and documentary risk in cross-border sales. A letter of credit allows a seller to receive payment from a bank if the required documents are presented in compliance with the credit terms, while the buyer gains assurance that payment will be made only against documentary presentation.
In Turkish practice, letters of credit are especially common in import-export transactions, commodity sales, machinery purchases, textile exports, construction materials, energy equipment, food trade, automotive supply, maritime trade and international distribution agreements. Turkey’s role as a major trading hub between Europe, Asia, the Middle East and North Africa makes documentary credits an important tool for commercial security.
A letter of credit is not merely a payment method. It is a legal and banking structure based on documentary compliance, bank independence and strict examination of documents. The underlying sales contract may involve goods, quality, delivery, delay or commercial disputes, but the bank’s payment obligation is usually assessed according to the letter of credit and the documents presented. This separation is one of the most important features of documentary credit law.
In Turkey, letters of credit are shaped by Turkish banking law, general contract law, commercial law, foreign trade practice, foreign exchange rules and international banking customs. In global trade, the most commonly used framework is the Uniform Customs and Practice for Documentary Credits, known as UCP 600, published by the International Chamber of Commerce. ICC materials describe documentary credit practice by reference to UCP 600 and related international standard banking practice, and emphasize that UCP and ISBP should be read as a whole in documentary credit practice.
This article explains letters of credit in Turkey, focusing on legal nature, trade finance use, UCP 600, bank obligations, documentary compliance, payment disputes, fraud risks and dispute resolution.
1. What Is a Letter of Credit?
A letter of credit is a bank undertaking issued at the request of a buyer, known as the applicant, in favor of a seller, known as the beneficiary. The issuing bank undertakes to pay, accept, negotiate or otherwise honor a compliant documentary presentation if the beneficiary presents the documents required under the credit.
The key feature is that the bank deals with documents, not with the goods themselves. If the documents comply with the credit terms, the bank may be obliged to pay even if there is a later dispute about the quality or condition of goods. Conversely, if the documents do not comply, payment may be refused even if the goods were actually shipped properly.
In a standard import letter of credit transaction, a Turkish importer asks its bank to issue a credit in favor of a foreign exporter. The exporter ships the goods and presents documents such as invoice, bill of lading, packing list, certificate of origin, insurance certificate and inspection certificate. The bank examines whether the documents comply with the credit. If they do, payment is made according to the credit terms.
In an export transaction, a Turkish exporter may request payment through a letter of credit issued by the buyer’s bank abroad. The exporter may also seek confirmation by a Turkish or foreign confirming bank to reduce issuing bank or country risk.
2. Legal Framework of Letters of Credit in Turkey
Turkey does not have a single statute dedicated exclusively to letters of credit. Instead, documentary credits are governed by a combination of contractual terms, banking law, Turkish commercial practice, general contract principles and international rules incorporated into the credit, especially UCP 600.
Turkish banks are regulated under Banking Law No. 5411, which governs banking activities, credit transactions, guarantees, payment services, foreign exchange transactions and supervision of banks. Banking Law No. 5411 identifies banking activities broadly and includes lending, guarantee transactions, payment and fund transfer transactions, foreign exchange transactions and other banking services within the regulated banking framework.
Where payment systems, payment services or electronic money structures are involved, Law No. 6493 on Payment and Securities Settlement Systems, Payment Services and Electronic Money Institutions may also be relevant. That law regulates payment systems, payment services, payment institutions and electronic money institutions in Turkey.
In practice, however, the core operational rules for letters of credit usually come from the text of the credit and incorporated international rules such as UCP 600. Parties should therefore pay close attention to whether the credit expressly states that it is subject to UCP 600.
3. Legal Nature of Letters of Credit
The legal nature of a letter of credit is based on independence. The letter of credit creates an autonomous banking obligation separate from the underlying sales contract between buyer and seller. The issuing bank’s obligation is not usually a guarantee of the buyer’s performance in the ordinary sense. Instead, it is an undertaking to honor a complying documentary presentation.
This independence is essential for international trade. The seller does not want to wait for the buyer to approve goods after arrival. The buyer does not want to pay before shipment. The bank acts as a neutral documentary payment mechanism. By focusing on documents, the letter of credit reduces commercial uncertainty.
However, independence does not mean that the letter of credit is immune from all legal challenge. Fraud, forged documents, clear abuse, sanctions, illegality, injunctions, insolvency and regulatory restrictions may affect payment in exceptional cases. Still, ordinary disputes about quality, delay, commercial dissatisfaction or breach of the sales contract generally do not automatically excuse the bank from honoring compliant documents.
4. Main Parties in a Letter of Credit
Several parties may participate in a letter of credit transaction.
The applicant is usually the buyer or importer. The applicant requests its bank to issue the credit and undertakes to reimburse the bank.
The issuing bank is the bank that issues the letter of credit and undertakes to honor a complying presentation.
The beneficiary is usually the seller or exporter. The beneficiary is entitled to present documents and demand payment if the presentation complies.
The advising bank advises the credit to the beneficiary. Its role is usually to authenticate and transmit the credit, not necessarily to pay.
The confirming bank adds its own independent undertaking to honor a complying presentation. Confirmation is important where the beneficiary wants protection against issuing bank risk or country risk.
The nominated bank is the bank authorized to honor or negotiate under the credit.
The reimbursing bank may be involved where payment is made through a reimbursement arrangement between banks.
The legal responsibilities of each party depend on the credit wording and applicable rules. A bank should not assume obligations beyond its role, and a beneficiary should understand which bank is actually obliged to pay.
5. UCP 600 and Documentary Credit Practice
UCP 600 is the most widely used international rule set for documentary credits. It is not a Turkish statute, but it becomes contractually binding when incorporated into the letter of credit. ICC sources describe UCP as central to documentary credit practice and explain that ISBP assists practitioners in applying UCP standards to document examination.
UCP 600 provides rules on issuance, advice, amendments, availability, presentation, examination of documents, discrepancies, honor, negotiation, reimbursement and bank responsibilities. It creates a standardized framework that reduces uncertainty in international trade.
In Turkey, banks and trade finance practitioners commonly use UCP 600 in import and export letters of credit. However, the parties should not assume UCP applies automatically. The credit should expressly state that it is subject to UCP 600. If it does not, disputes may be governed primarily by the credit wording, Turkish law and general banking practice.
6. Documentary Principle
The documentary principle means that banks examine documents, not goods, services or performance. A bank is not expected to inspect containers, test product quality, verify factory performance or decide whether contractual delivery obligations were commercially satisfied.
For example, if the letter of credit requires a clean on-board bill of lading, commercial invoice and insurance certificate, the bank examines those documents. If they appear compliant on their face, the bank may honor the presentation. If the buyer later claims that the goods were defective, that dispute is usually between buyer and seller under the sales contract.
This principle protects the speed and reliability of trade finance. If banks had to investigate every underlying commercial dispute before payment, letters of credit would lose much of their function.
However, banks must examine documents carefully. A bank that pays against clearly discrepant documents may lose reimbursement rights against the applicant. A bank that wrongfully refuses compliant documents may face liability to the beneficiary.
7. Independence Principle
The independence principle separates the letter of credit from the underlying contract. The buyer’s defenses under the sales contract do not automatically become defenses available to the bank. This allows the beneficiary to rely on the bank’s payment undertaking rather than the buyer’s solvency or willingness to pay.
For Turkish exporters, independence is valuable because it reduces counterparty risk. A foreign buyer may become insolvent, refuse payment or raise commercial objections after shipment. If the exporter has a confirmed letter of credit and presents compliant documents, payment risk is shifted toward the bank.
For Turkish importers, independence creates risk. If the documents are compliant but the goods are defective, the importer may still need to reimburse the bank and then pursue claims against the seller. Therefore, importers must draft documentary conditions carefully to ensure that required documents provide meaningful protection.
8. Types of Letters of Credit Used in Turkey
Several types of letters of credit are used in Turkish trade finance.
A sight letter of credit is payable upon presentation of compliant documents.
A deferred payment letter of credit provides payment at a future date after document acceptance.
An acceptance credit involves acceptance of a draft payable at maturity.
A negotiation credit allows a nominated bank to negotiate documents.
A confirmed letter of credit includes an additional undertaking by a confirming bank.
A transferable letter of credit allows the beneficiary to transfer rights to another party, often used by intermediaries.
A back-to-back letter of credit involves one credit used as security for another credit, common in intermediary trade.
A standby letter of credit functions more like a security instrument and may be used as a guarantee of payment or performance, though it differs from a commercial documentary credit.
The correct type depends on the commercial transaction, risk allocation, financing need, buyer-seller relationship, country risk and bank requirements.
9. Import Letters of Credit in Turkey
Turkish importers use letters of credit to purchase goods from foreign sellers while controlling payment conditions. The importer instructs its Turkish bank to issue a credit in favor of the foreign supplier. The bank usually requires credit approval, collateral, cash margin, account limits or other reimbursement arrangements.
The importer should ensure that the credit terms match the sales contract. If the contract requires shipment by a certain date, inspection certificate, origin certificate or specific transport documents, the letter of credit should reflect those requirements precisely.
A common mistake is using vague or inconsistent documentary conditions. If the sales contract and letter of credit conflict, disputes may arise. The bank follows the credit, not the entire commercial contract. Therefore, importers must translate commercial protections into clear documentary requirements.
10. Export Letters of Credit in Turkey
Turkish exporters use letters of credit to reduce payment risk in cross-border sales. An exporter may prefer a confirmed letter of credit where the buyer is located in a politically or financially risky jurisdiction, or where the issuing bank is unfamiliar.
For exporters, the greatest risk is document discrepancy. Even minor differences in names, dates, descriptions, shipment terms, quantities, documents or signatures may lead to refusal. Exporters should not treat document preparation as an administrative task. It is the legal condition for payment.
Turkish exporters should coordinate with freight forwarders, insurers, chambers of commerce, inspection companies and banks before shipment. Documents should be checked against the credit terms, not merely against the sales contract.
11. Confirmed Letters of Credit
A confirmed letter of credit gives the beneficiary an additional payment undertaking from the confirming bank. This is valuable where the beneficiary does not want to rely solely on the issuing bank or the buyer’s country.
Confirmation may protect against issuing bank insolvency, country transfer restrictions, political risk or foreign exchange problems. However, confirmation increases cost. The confirming bank charges fees and will examine documents strictly.
For Turkish exporters, confirmation can be particularly useful in sales to high-risk markets. For Turkish importers, confirmation may increase total transaction cost but may be required by foreign sellers.
12. Discrepancies in Letter of Credit Documents
Document discrepancies are the most common source of letter of credit disputes. A discrepancy exists where the presented documents do not comply with the credit terms or applicable rules.
Common discrepancies include:
Wrong beneficiary or applicant name, inconsistent goods description, late shipment, expired credit, missing document, unsigned invoice, incorrect bill of lading date, shipment from wrong port, partial shipment not allowed, insurance coverage insufficient, inconsistent quantities, wrong currency, missing certificate, stale transport document or presentation after deadline.
Banks examine documents on their face. They do not usually correct or interpret commercial intentions beyond the document requirements. A beneficiary should therefore prepare documents with technical precision.
If discrepancies exist, the issuing bank may refuse documents or ask the applicant to waive discrepancies. The applicant may accept or reject waiver. If the applicant rejects, the beneficiary may face non-payment unless the refusal is wrongful.
13. Bank’s Document Examination Duty
Banks must examine whether documents appear to comply with the credit. This duty requires professional care but is limited to documentary examination. The bank does not authenticate every factual statement unless the rules or credit require it.
The examining bank must act within the time allowed by applicable rules. It must identify discrepancies clearly if refusing documents. A vague refusal may create dispute.
For Turkish banks, internal trade finance procedures are important. Banks should preserve document examination records, discrepancy notices, SWIFT messages, customer instructions, waiver responses and reimbursement records. These records may be decisive in litigation.
14. Applicant’s Reimbursement Obligation
The applicant usually signs a reimbursement agreement or credit facility documentation with the issuing bank. If the bank honors a complying presentation, the applicant must reimburse the bank according to their agreement.
The applicant may object if the bank paid against discrepant documents, exceeded authority, ignored the credit terms or violated an injunction. However, if the presentation was compliant, the applicant generally cannot refuse reimbursement merely because the underlying goods were defective.
This is a major legal and commercial point. Importers should understand that a letter of credit shifts focus from goods to documents. To protect against poor-quality goods, the importer should require inspection certificates, quality certificates, detailed packing documents or independent verification documents as credit conditions.
15. Fraud Exception
The fraud exception is a narrow but important limitation on the independence principle. If documents are forged or the beneficiary’s demand is clearly fraudulent, courts may intervene in exceptional cases.
Fraud allegations must be supported by strong evidence. A buyer’s general complaint that goods are defective is not enough. The applicant must show serious, clear and objective evidence of fraud, such as forged transport documents, nonexistent shipment, false inspection documents or collusion.
In Turkey, an applicant seeking to stop payment may apply for an interim injunction. Courts are generally cautious because excessive injunctions would weaken the reliability of letters of credit. The applicant must show urgency, legal interest and strong evidence.
16. Injunctions Against Letter of Credit Payment
Injunctions are sometimes requested to prevent banks from paying under a letter of credit. These applications are usually urgent because once payment is made, the applicant’s remedy may shift to a recovery action against the beneficiary.
Turkish courts may examine whether there is clear fraud, abuse of rights, illegality, sanctions issue or a serious documentary defect. Ordinary commercial disputes usually do not justify stopping payment.
The applicant should file a carefully prepared petition with the credit, documents, correspondence, evidence of fraud and explanation of irreparable harm. The bank should be notified clearly if an injunction is granted. Paying after a valid court order may create liability.
17. Letter of Credit and Bills of Lading
Transport documents are central in letter of credit transactions. The bill of lading often represents shipment and may control delivery of goods. Banks examine whether the bill of lading complies with the credit: loading date, ports, consignee, notify party, clean notation, freight terms, originals and endorsements.
Disputes often arise where the bill of lading is inconsistent with the invoice, shipment is late, goods are transshipped contrary to the credit, or the bill of lading contains clauses suggesting defective shipment.
Importers should draft transport document requirements carefully. Exporters should coordinate with carriers and freight forwarders to avoid documentary errors.
18. Incoterms and Letters of Credit
Incoterms and letters of credit must be aligned. If the sales contract uses FOB, CIF, CFR, FCA or another Incoterm, the credit should require documents consistent with that delivery structure.
For example, if the transaction is CIF, insurance documents are expected. If the transaction is FOB, the buyer may arrange freight and insurance differently. If the letter of credit requires documents inconsistent with the Incoterm, the beneficiary may struggle to comply.
Trade finance lawyers should review sales contracts, Incoterms and letter of credit drafts together before issuance.
19. Sanctions and Compliance Risks
Banks may refuse or delay letter of credit transactions due to sanctions, AML, export control, dual-use goods, prohibited jurisdictions or suspicious trade patterns. Trade finance is a high-risk area for financial crime because documents can be manipulated and goods may be misdescribed.
Banks in Turkey must comply with banking regulation, AML obligations and internal compliance policies. Banking Law No. 5411 regulates banking activities and supervision, while Law No. 6493 regulates payment systems and payment services where payment infrastructure is relevant.
A letter of credit involving sanctioned parties, restricted goods or suspicious routing may be blocked. Parties should conduct sanctions and compliance checks before shipment.
20. AML and Trade-Based Money Laundering
Letters of credit may be misused for trade-based money laundering. Fraudsters may over-invoice, under-invoice, use false documents, misdescribe goods, ship phantom goods, use shell companies or route transactions through high-risk jurisdictions.
Banks should apply customer due diligence, trade document review, transaction monitoring and suspicious transaction procedures. Exporters and importers should maintain consistent invoices, transport documents, customs records and payment records.
If documents are inconsistent or the transaction has no commercial logic, banks may request explanations or refuse processing.
21. Foreign Exchange and Payment Issues
Letters of credit often involve foreign currency. Turkish importers and exporters must consider foreign exchange rules, bank processing requirements, customs documentation, tax implications and payment restrictions.
Payment under a letter of credit may involve SWIFT messages, correspondent banks, reimbursement banks and foreign currency transfers. Delays can occur due to compliance screening, document discrepancies, country risk or banking holidays.
Parties should plan timing carefully. A documentary credit is only reliable if the documents, shipment, presentation and payment mechanics are coordinated.
22. Disputes Between Applicant and Beneficiary
The underlying sales dispute between buyer and seller may continue even after the bank pays or refuses under the letter of credit. If the seller ships defective goods, the buyer may sue for breach of contract. If the buyer refuses to waive discrepancies in bad faith, the seller may claim damages depending on the facts.
However, the bank’s role remains separate. A sales contract dispute does not automatically determine the bank’s payment obligation unless fraud, illegality or credit terms are directly affected.
The sales contract should include governing law, jurisdiction or arbitration clauses, quality standards, inspection rights, rejection rights, damages, liquidated damages and documentary obligations.
23. Disputes Between Applicant and Bank
An applicant may dispute reimbursement if the bank paid despite discrepancies. The applicant may argue that the bank failed to examine documents properly, ignored credit terms, paid after expiry or violated instructions.
The bank will defend itself by showing that documents complied or that the applicant waived discrepancies. Evidence includes credit text, amendments, presented documents, examination notes, discrepancy notices, waiver instructions and SWIFT correspondence.
These disputes are often technical. Courts may need banking experts familiar with UCP 600 and documentary credit practice.
24. Disputes Between Beneficiary and Bank
A beneficiary may sue if the bank wrongfully refuses documents or fails to honor a complying presentation. The beneficiary must show that the documents were presented on time and complied with the credit.
The bank may defend itself by identifying discrepancies, expiry, late presentation, lack of authorization or sanctions restrictions. If the credit is confirmed, the confirming bank’s independent obligation may become central.
The wording of the refusal notice is important. A bank that refuses documents should state discrepancies clearly and preserve evidence.
25. Evidence in Letter of Credit Disputes
Evidence in letter of credit disputes is documentary by nature. Important evidence includes:
The sales contract, pro forma invoice, letter of credit text, UCP 600 incorporation clause, amendments, SWIFT messages, presented documents, transport documents, invoices, insurance certificates, inspection certificates, certificates of origin, discrepancy notices, waiver communications, bank internal examination records, payment records, reimbursement documents, customs records and correspondence.
In fraud cases, evidence may also include carrier confirmations, customs records, expert reports, police complaints, inspection evidence and proof of forged documents.
26. Arbitration and Litigation
International sales contracts often include arbitration clauses. However, letter of credit disputes involving banks may be governed by separate banking documents and jurisdiction clauses.
A dispute between buyer and seller may go to arbitration, while a dispute between applicant and issuing bank may go to Turkish courts under the bank’s credit agreement. A dispute involving confirming bank may be subject to another jurisdiction.
Parties should align dispute resolution clauses carefully. Fragmented dispute resolution can increase cost and risk.
27. Practical Checklist for Turkish Importers
Turkish importers should:
Draft credit terms consistent with the sales contract.
Require meaningful documents, not vague promises.
Check shipment date, expiry date and presentation period.
Use inspection certificates where quality risk is high.
Understand reimbursement obligations to the bank.
Review discrepancy waiver requests carefully.
Act quickly if fraud is suspected.
Preserve all correspondence and bank notices.
28. Practical Checklist for Turkish Exporters
Turkish exporters should:
Request UCP 600 incorporation.
Consider confirmed credit for high-risk buyers or countries.
Review the letter of credit before shipment.
Check every document against the credit.
Coordinate with freight forwarders, insurers and chambers.
Avoid inconsistent goods descriptions.
Present documents before the deadline.
Respond promptly to discrepancy notices.
Keep copies of all documents and SWIFT communications.
29. Practical Checklist for Banks
Banks should:
Define their role clearly: issuing, advising, confirming or nominated bank.
Use clear credit wording.
Apply UCP 600 consistently where incorporated.
Examine documents professionally.
Issue discrepancy notices clearly and on time.
Preserve documentary records.
Apply sanctions and AML screening.
Train trade finance staff.
Avoid giving informal advice that conflicts with credit terms.
Comply with court injunctions where validly served.
30. Why Legal Support Is Important
Letters of credit require legal and technical expertise. A Turkish banking and trade finance lawyer may assist with credit drafting, sales contract alignment, UCP 600 analysis, discrepancy disputes, injunction applications, fraud claims, bank reimbursement disputes, export payment disputes, sanctions review, arbitration strategy and litigation.
Legal support is especially important in high-value commodity trade, machinery imports, confirmed credits, back-to-back credits, transferable credits, suspected fraud, sanctions-sensitive transactions and disputes involving multiple jurisdictions.
Conclusion
Letters of credit in Turkey are essential instruments for international trade finance. They provide payment security for exporters and documentary control for importers. Their legal power comes from independence, documentary compliance and standardized banking practice, especially where UCP 600 is incorporated.
However, letters of credit are not risk-free. Importers may be required to reimburse banks even where goods are defective if documents comply. Exporters may lose payment due to minor document discrepancies. Banks may face liability for wrongful payment or wrongful refusal. Fraud, sanctions, AML concerns, forged documents and court injunctions may complicate payment.
The strongest letter of credit structure begins before issuance. The sales contract, Incoterms, documentary requirements, shipment schedule, bank roles, confirmation, expiry date and dispute resolution clause must be aligned. Once documents are presented, technical compliance becomes decisive.
In Turkish trade finance law, a letter of credit is not merely a payment instruction. It is a sophisticated legal and banking instrument. Its success depends on precise drafting, disciplined document preparation, professional bank examination and fast legal action when disputes arise.
