Foreign Back‑to‑Back (B2B) Letter of Credit

A Back-to-Back Letter of Credit (B2B LC) is a specialized trade finance instrument commonly used in export-oriented industries, particularly in the garment, textile, leather, and manufacturing sectors. It is issued against the security of a master or export Letter of Credit received from a foreign buyer.

In a typical Back-to-Back LC transaction, an exporter receives an export LC from an overseas buyer and uses that export LC as collateral to open another LC in favor of suppliers of raw materials, accessories, packaging materials, or machinery needed to fulfill the export order. This arrangement enables exporters to procure inputs without making immediate cash payments.

A Foreign Back-to-Back LC contains various sections that define the rights, obligations, and responsibilities of all parties involved. Understanding its structure is essential for exporters, bankers, trade finance professionals, auditors, and compliance officers.

Meaning of a Foreign Back-to-Back LC

A Foreign Back-to-Back Letter of Credit is an irrevocable documentary credit opened by an exporter in favor of a foreign supplier against the security of a master export LC.

The primary purpose of the B2B LC is to facilitate the import of raw materials and inputs required for export production. The amount, shipment schedule, and payment terms of the B2B LC are generally aligned with the terms of the master export LC.

Because the B2B LC is issued against an existing export LC, banks carefully monitor both credits to ensure that the exporter's obligations under the export contract can be fulfilled.

Structure of a Foreign B2B LC

Massage Header

The message header is the identification section of the Letter of Credit and contains information about the banks involved in the transaction. This section ensures secure communication through the SWIFT network and establishes the authenticity of the credit.

The message header generally includes:

• Name of the issuing bank
• Branch address of the issuing bank
• SWIFT code of the issuing bank
• Name of the advising bank
• Address of the advising bank
• SWIFT code of the advising bank

These details facilitate secure and internationally recognized transmission of LC instructions between financial institutions.

Message Text and Credit Type

Following the header, the LC contains the operative terms and conditions governing the transaction. The credit is usually issued as an Irrevocable Documentary Credit, meaning it cannot be amended or cancelled without the consent of all relevant parties.

The LC typically states that it is subject to UCP 600, the Uniform Customs and Practice for Documentary Credits issued by the International Chamber of Commerce (ICC). UCP 600 provides internationally accepted rules regarding the issuance, amendment, presentation, examination, and payment of documentary credits, thereby ensuring consistency in global banking practice.

Key Parties & terms Involved in the B2B LC

Applicant Bank

The Applicant Bank is the issuing bank that opens the Back-to-Back LC.

Typical responsibilities include:

• Issuing the credit
• Examining import documents
• Making payment upon maturity
• Monitoring export performance

The applicant bank generally assesses:

• Export LC value
• Exporter's performance record
• Import entitlement
• Regulatory compliance requirements

Applicant (Exporter)

The exporter acts as the applicant under the Back-to-Back LC.

The exporter:

• Holds the master export LC
• Requires raw materials or accessories
• Requests issuance of the B2B LC
• Remains responsible for payment obligations

Examples include:

• Garment manufacturers
• Textile exporters
• Footwear manufacturers
• Leather product exporters

Beneficiary

The overseas supplier (e.g., a foreign trading corporation) who supplies goods under the Back‑to‑Back LC.

Advising Bank

The advising bank is usually located in the supplier's country.

Its role includes:

• Authenticating the LC
• Advising the credit to the supplier
• Confirming authenticity of amendments

The advising bank generally assumes no payment liability unless it also acts as confirming bank.

Negotiating Bank

The negotiating bank:

• Receives export documents
• Examines documentary compliance
• Negotiates or forwards documents
• Claims reimbursement from the issuing bank

Often the advising bank and negotiating bank are the same institution.

Credit Amount, Currency and Payment Terms

The credit specifies the currency and maximum amount available under the LC. The amount must normally remain within the approved percentage of the underlying export LC value to protect the issuing bank's interests.

Common currencies include:

• United States Dollar (USD)
• Euro (EUR)
• Pound Sterling (GBP)
• Japanese Yen (JPY)

The payment terms determine when the beneficiary will receive payment. Depending on the agreement, payment may be made through:

• Deferred payment arrangements
• Usance drafts
• Acceptance credits

For example, an LC may state that payment will be made 90 days from the date of acceptance, allowing the exporter time to receive export proceeds before settling import liabilities.

Shipment and Delivery Terms

The shipment section outlines how and when the goods must be transported. Compliance with shipment instructions is critical because deviations can result in documentary discrepancies.

The LC normally specifies:

• Port of loading
• Port of discharge
• Latest shipment date
• Partial shipment conditions
• Transshipment conditions
• Mode of transportation

Unless specifically prohibited, partial shipment and transshipment are generally allowed. However, the supplier must ensure that shipment takes place within the stipulated timeframe.

Description of Goods

One of the most important sections of the B2B LC is the detailed description of goods. The information contained in this section must match the Proforma Invoice and supporting commercial documents exactly.

Typical details include:

• Commodity description
• HS Code
• Quantity
• Unit price
• Total value
• Product specifications

Even minor discrepancies between the LC and shipping documents may create problems during document negotiation and payment processing.

Incoterms

The delivery terms (e.g., CNF/C&F – Incoterms) define responsibilities for freight and insurance.

Documents Required Under the B2B LC

Mandatory Shipping and Commercial Documents

Banks operate on the principle of documentary compliance. Therefore, suppliers must provide specific documents required by the LC.

Commercial Invoice

The commercial invoice serves as the primary billing document and must:

• Be item-wise
• Show quantity and price clearly
• Mention LC number
• Refer to the master export LC where required

Packing List

The packing list provides detailed information regarding:

• Number of packages
• Weight
• Dimensions
• Contents of each package

Bill of Lading

A full set of clean "Shipped on Board" Bills of Lading is usually required. The document should:

• Indicate freight prepaid status
• Be issued to the order of the issuing bank
• Show package quantity and shipping details clearly

Certificates and Declarations

In addition to shipping documents, several certificates may be required to confirm compliance with LC conditions.

Common certificates include:

Certificate of Origin

Issued by the Chamber of Commerce or authorized authority, this document verifies the country where the goods were manufactured or produced.

Beneficiary's Certificate

The supplier may be required to certify that:

• Shipment complies with the Proforma Invoice
• Goods meet LC specifications
• Non-negotiable documents have been dispatched to the applicant

Pre-Shipment Inspection Certificate

This certificate confirms that the goods have been inspected and comply with the required quality and quantity standards.

Special Conditions and Compliance Requirements

The LC may contain special clauses regarding document discrepancies, shipping restrictions, and compliance requirements.

Important provisions often include:

• Discrepant documents must not be negotiated without prior approval.
• Unauthorized shipment deviations are not permitted.
• Compliance with international sanctions is mandatory.
• Certain vessels or countries may be prohibited under applicable regulations.

These clauses are intended to protect both the issuing bank and applicant exporter from unnecessary risks.

Insurance Arrangement

The responsibility for insurance depends on the agreed Incoterms and LC conditions. In most Back-to-Back LC transactions, insurance is arranged by the LC opener or applicant.

After shipment, the supplier is usually required to provide shipment details immediately to the designated insurance company, including:

• Vessel information
• Shipment date
• Invoice value
• Description of goods

This ensures timely activation of cargo insurance coverage.

Presentation and Negotiation Rules

The supplier must present documents within the period specified in the LC. Failure to present documents within the stipulated time may result in payment delays or refusal.

The negotiating bank is generally required to:

• Examine documents carefully
• Notify the issuing bank before negotiation
• Send documents through reputable courier services
• Provide SWIFT or electronic confirmation where required

Compliance with these procedures facilitates smooth document handling and reimbursement.

Steps of Back-to-Back (B2B) Letter of Credit

A Back-to-Back Letter of Credit (B2B LC) is issued by a bank against the security of a master export Letter of Credit received from a foreign buyer. It enables an exporter to import raw materials, fabrics, accessories, packaging materials, or other inputs required for manufacturing goods intended for export. The process involves coordination among the exporter, issuing bank, foreign supplier, and various intermediary banks to ensure smooth execution of both import and export transactions.

Step 1: Receipt of Export Letter of Credit

The process begins when the exporter receives an export LC from a foreign buyer. This export LC serves as the security against which the Back-to-Back LC will be opened.

The exporter reviews the export LC to verify:

• Buyer information
• Product specifications
• Shipment schedule
• Export value
• Payment terms
• Validity period

Only after confirming that the export LC is valid and workable does the exporter proceed with the B2B LC application.

Step 2: Submission of Application for B2B LC

The exporter applies to the bank for opening a Back-to-Back LC in favor of foreign suppliers.

Generally, the exporter submits:

• B2B LC application form
• Master export LC
• Accepted export order
• Proforma Invoice from supplier
• Import entitlement documents
• Bonded warehouse license (where applicable)
• Insurance information
• Other documents required by the bank

The bank scrutinizes the application before approval.

Step 3: Assessment and Approval by the Bank

The issuing bank evaluates the request to determine whether the B2B LC can be issued.

The bank examines:

• Authenticity of the export LC
• Exporter's creditworthiness
• Value of the export order
• Past export performance
• Compliance with foreign exchange regulations
• Availability of import entitlement

If the proposal satisfies banking requirements, approval is granted.

Step 4: Issuance of Back-to-Back LC

After approval, the bank issues the Back-to-Back LC in favor of the foreign supplier.

The LC contains important details such as:

• Beneficiary's name and address
• LC value
• Currency
• Description of goods
• Quantity
• Unit price
• Shipment terms
• Ports of loading and discharge
• Required documents
• Payment terms

The B2B LC is usually issued through the SWIFT system.

Step 5: Advising of LC to Supplier

The LC is transmitted to the supplier's bank, known as the advising bank.

The advising bank:

• Verifies the authenticity of the LC
• Advises the credit to the beneficiary
• Explains terms and conditions if required

The supplier receives the LC and reviews all conditions carefully.

Step 6: Procurement and Shipment of Goods

After accepting the LC terms, the supplier manufactures or procures the goods and arranges shipment according to the LC conditions.

The supplier must ensure compliance with:

• Product specifications
• Quantity requirements
• Shipment deadline
• Packaging standards
• Transportation conditions

Any deviation may result in documentary discrepancies.

Step 7: Preparation of Shipping Documents

Once shipment has been completed, the supplier prepares the documents required under the LC.

These commonly include:

• Commercial Invoice
• Packing List
• Bill of Lading or Air Waybill
• Certificate of Origin
• Inspection Certificate
• Beneficiary's Certificate
• Other documents specified in the LC

All documents must strictly comply with LC requirements.

Step 8: Presentation of Documents to Negotiating Bank

The supplier submits the shipping documents to the negotiating bank within the presentation period stated in the LC.

The negotiating bank examines the documents based on:

• LC terms
• UCP 600 rules
• International Standard Banking Practice (ISBP)

If documents comply, the bank accepts or negotiates them.

Step 9: Forwarding of Documents to Issuing Bank

After examination, the negotiating bank sends the documents to the issuing bank in Bangladesh.

The issuing bank independently reviews the documents to verify compliance.

The examination focuses on:

• Shipment date
• Document consistency
• Quantity and value
• LC compliance
• Presentation deadline

Step 10: Acceptance and Lodgment of Documents

If the documents are found compliant, the issuing bank accepts them and lodges the import bill.

At this stage:

• Import liability is recorded
• Foreign currency obligation is created
• Accounting entries are passed
• Maturity date is calculated in case of usance payment

Where discrepancies exist, approval from the exporter may be required before acceptance.

Step 11: Delivery of Imported Materials to Exporter

After document acceptance, the exporter receives the necessary documents for customs clearance and takes delivery of the imported raw materials.

The exporter then uses these materials for manufacturing goods required under the master export LC.

Step 12: Production and Export of Finished Goods

Using the imported materials, the exporter produces finished products and ships them to the foreign buyer according to the export LC.

The exporter prepares export documents such as:

• Commercial Invoice
• Packing List
• Bill of Lading
• Certificate of Origin
• Inspection Certificates

These documents are submitted under the export LC.

Step 13: Receipt of Export Proceeds

The foreign buyer's bank makes payment under the export LC after receiving compliant export documents.

The export proceeds are credited to the exporter's account through the banking channel.

The bank adjusts:

• Export bills
• Outstanding B2B liabilities
• Interest and charges, if any

Step 14: Settlement of Back-to-Back LC Liability

Upon receipt of export proceeds, the issuing bank settles the payment due under the Back-to-Back LC.

The bank remits funds to:

• Negotiating bank
• Reimbursing bank
• Beneficiary's bank

depending on the LC arrangement.

Step 15: Closure of B2B LC File

After payment and adjustment, the bank closes the B2B LC file.

The bank verifies:

• Import documents
• Export realization
• Regulatory compliance
• Foreign exchange reporting requirements

Once all obligations are fulfilled, the transaction is treated as completed.

Conclusion

The structure of a Foreign Back-to-Back Letter of Credit is designed to provide a clear framework governing the rights and responsibilities of exporters, suppliers, and banks. It incorporates essential elements such as credit terms, shipment instructions, payment conditions, documentary requirements, compliance clauses, and legal provisions. A proper understanding of each section is critical for avoiding discrepancies, ensuring payment security, maintaining compliance with UCP 600, and facilitating the successful execution of international trade transactions.
