Lesson 9.1: Master Letter of Credit (L/C) Fundamentals
1. Introduction
In the international apparel export industry, cross-border trade involves manufacturing massive volumes of garments—often worth hundreds of thousands or millions of dollars—for buyers located thousands of miles away.
For an apparel manufacturer in Bangladesh, producing 50,000 shirts requires significant upfront capital investment to procure raw cotton, knit yarn, dye fabric, buy zippers and buttons, and pay sewing labor. Conversely, international retail buyers hesitate to pay advance cash before verifying that the garments have been manufactured to exact technical specifications and loaded on board a cargo vessel.
To bridge this trust gap between international buyers and overseas garment factories, international trade relies on the Letter of Credit (L/C)—the most secure, standardized, and universally recognized financial settlement instrument in global commerce.
For a Commercial Executive in a garment factory, mastering the fundamentals of a Master Letter of Credit is not merely an administrative skill; it is the foundational pillar of the entire commercial career. Every downstream operational task—opening raw material Back-to-Back (BTB) L/Cs, applying for Utilization Declarations (UD), issuing EXP forms, clearing customs, booking cargo space, and realizing export proceeds—is directly governed by the terms of the Master L/C.
Disclaimer: This training lesson provides operational standard operating procedures for educational purposes under international commercial practice. Because banking laws, foreign exchange guidelines (e.g., Bangladesh Bank Guidelines for Foreign Exchange Transactions), and customs regulations change periodically, commercial personnel must verify active transactional requirements with their authorized dealer negotiating banks and statutory bodies.
2. What Is a Letter of Credit (L/C)?
A Letter of Credit (L/C)—formally termed a Documentary Credit—is a legally binding written undertaking issued by a financial institution (the Issuing Bank) on behalf of a buyer (the Applicant), promising to pay a specified sum of money to the seller (the Beneficiary), provided that the seller presents a set of strictly conforming shipping documents within a stipulated deadline.
CORE DEFINITION OF A LETTER OF CREDIT
The Golden Rule of Documentary Credits: UCP 600
International Letters of Credit are governed worldwide by the Uniform Customs and Practice for Documentary Credits (ICC Publication No. 600, or UCP 600), published by the International Chamber of Commerce (ICC) in Paris.
Two foundational legal principles under UCP 600 govern all L/C operations:
- Article 4 (Independence of Credit): A Letter of Credit is by its nature a separate transaction from the underlying sales contract or purchase order (PO). The bank is in no way concerned with or bound by such contracts, even if referenced in the credit.
- Article 5 (Documents versus Goods/Services): In credit operations, banks deal with documents alone and not with goods, services, or performance to which the documents may relate.
Commercial Implication: The issuing bank does not inspect garments at the factory; they only examine the physical paperwork (Commercial Invoice, Bill of Lading, Packing List, Certificate of Origin). If the paperwork complies 100% with the L/C terms, the bank must release payment, even if the buyer claims a commercial dispute. Conversely, even if the garments are 100% flawless, a single typographical error on the documents allows the bank to refuse payment.
3. Why Buyers and Sellers Use Letters of Credit
International trade entails significant cross-border risks: geographical distance, differing legal systems, currency fluctuations, and political instability. The Letter of Credit balances the conflicting financial objectives of buyers and sellers:
SELLER / EXPORTER PERSPECTIVE
BUYER / IMPORTER PERSPECTIVE
Key Advantages in Garment Manufacturing:
- Collateral for Raw Materials: In Bangladesh, an export Master L/C acts as financial collateral allowing the factory to open Back-to-Back (BTB) L/Cs to import yarn, fabric, and accessories without putting up upfront cash.
- Export Credit Facilities: Commercial banks provide pre-shipment Packing Credit (PC) and Export Cash Credit (ECC) loans against a valid Master L/C to fund factory working capital and payroll.
- Statutory Compliance: Under Bangladesh foreign exchange regulations, apparel exports and duty-free bonded raw material imports require an authenticated Master L/C or registered sales contract.
4. The 6 Main Parties in a Letter of Credit
Every documentary credit transaction involves specific institutions and legal entities. A Commercial Executive must understand the exact role and legal obligations of each party:
THE 6 PRIMARY PARTIES IN AN EXPORT L/C
| # | Party | Identity in Garment Trade | Primary Legal & Financial Role |
|---|---|---|---|
| 01 | Applicant | Foreign Buyer / Importer (e.g., H&M, Zara, Walmart) | Requests the issuing bank to open the L/C; reimburses the issuing bank upon release of compliant documents. |
| 02 | Issuing Bank | Buyer's Bank (e.g., BNP Paribas, HSBC Paris) | Issues the L/C; takes on the irrevocable legal commitment to pay the beneficiary against compliant documents. |
| 03 | Beneficiary | Garment Factory / Exporter (e.g., Apex Apparels Ltd.) | The seller in whose favor the credit is opened; manufactures goods and presents shipping documents. |
| 04 | Advising Bank | Exporter's Local Bank (e.g., Eastern Bank PLC, Dhaka) | Authenticates the SWIFT message and forwards (advises) the official L/C copy to the factory beneficiary. |
| 05 | Nominated Bank | Negotiating Bank (Often the Advising Bank) | The bank authorized in the L/C to receive documents, examine compliance, and negotiate/pay the exporter. |
| 06 | Confirming Bank | First-Class International Bank (Optional - for high-risk mkts) | Adds an independent payment guarantee to the L/C at the request of the issuing bank, eliminating country risk. |
5. The Standard Export L/C Workflow (8-Stage Lifecycle)
The execution of an export Letter of Credit follows a strict chronological sequence from contract negotiation to foreign currency realization:
1. Contract / Proforma Invoice (PI) Signed by Parties
Stage-by-Stage Operational Walkthrough:
- Sales Agreement: Buyer and factory finalize order terms (Quantity, Price, Incoterms, Ship Date) via a signed Proforma Invoice (PI) or Purchase Order (PO).
- L/C Application: Buyer submits an application to their bank, depositing cash collateral or using their corporate credit facility.
- SWIFT Transmission: Issuing bank generates and sends an authenticated electronic SWIFT MT700 message to the seller's bank in Bangladesh.
- Advising & Notification: The local advising bank verifies the digital signature/encryption of the SWIFT message and sends an official advising copy to the factory's commercial department.
- Manufacturing & Shipment: Factory audits the L/C terms, procures raw materials, completes garment production, books cargo space, passes customs clearance, and loads goods onto the ocean vessel or cargo aircraft.
- Document Presentation: Factory prepares the required shipping documents (Invoices, Packing Lists, Bills of Lading, COO) and submits them to their local negotiating bank within the presentation period.
- Document Dispatch: Local bank examines the paperwork for compliance and dispatches the original courier set to the foreign issuing bank.
- Settlement & Cargo Delivery: The issuing bank examines documents under UCP 600. If clean, they remit payment via SWIFT MT103/MT202 to the seller's bank, and release the original Bill of Lading to the buyer to claim cargo at the destination seaport.
6. Applicant vs Beneficiary
Understanding the legal distinction between the Applicant and Beneficiary is fundamental:
| Comparative Parameter | The Applicant (Buyer) | The Beneficiary (Seller / Factory) |
|---|---|---|
| Role | Buyer / Importer | Manufacturer / Exporter |
| Legal Relationship | Customer of the Issuing Bank | Recipient of the Bank's Payment Undertaking |
| Financial Duty | Pays bank fees, reimburses credit amount | Prepares and presents compliant shipping documents |
| Control over L/C | Dictates initial terms during application | Must accept or request formal amendments to terms |
| Garment Industry Context | Overseas brand or retailer (e.g., C&A, Next, Target) | Apparel manufacturing enterprise in Bangladesh |
7. Issuing Bank vs Advising Bank
Banks act as neutral financial intermediaries ensuring strict contract fulfillment:
ISSUING BANK vs ADVISING BANK
| Issuing Bank (Buyer's Bank) | Advising Bank (Seller's Bank) |
|---|---|
| - Located in buyer's country - Assumes 100% financial liability - Examines documents for payment - Reimburses negotiating bank | - Located in exporter's country (Bangladesh) - Assumes NO payment obligation (unless adding confirmation) - Authenticates SWIFT message validity and delivers to seller - Acts as local agent facilitating document submission |
8. Confirming Bank & Country Risk Mitigation
Under normal circumstances, an export L/C is unconfirmed, meaning payment relies solely on the financial stability of the foreign issuing bank and the political stability of the buyer's country.
When Is a Confirming Bank Needed?
If an export order originates from a buyer in an economically unstable, politically volatile, or foreign-currency-constrained nation (or if the issuing bank is small and unrecognized globally), the exporter faces Country Risk and Bank Default Risk.
To eliminate this risk, the exporter requests a Confirmed L/C. A Confirming Bank (usually a top-tier global bank like Citibank N.A., Standard Chartered, or HSBC) adds its own irrevocable, independent undertaking to pay the beneficiary.
Commercial Benefit: If the foreign issuing bank fails or if the buyer's government restricts foreign currency remittances, the Confirming Bank is legally required to pay the factory in full, provided compliant documents are submitted.
9. Key Fields in an Export Master L/C
While the comprehensive field-by-field SWIFT breakdown is mastered in Lesson 9.2, a Commercial Executive must instantly recognize these core data elements in every Master L/C:
| Field Code | Field Name | Commercial Meaning | Critical Verification Point |
|---|---|---|---|
| 27 | Sequence of Total | Message pagination (e.g., 1/1) | Ensures no missing pages in SWIFT transmission |
| 40A | Form of Documentary Credit | Type of credit (IRREVOCABLE) | Must state "IRREVOCABLE" (cannot be canceled unilaterally) |
| 20 | Documentary Credit Number | Unique L/C reference number | Required on all shipping invoices and certificates |
| 31C | Date of Issue | Official date credit was opened | Establishes commercial timeline |
| 31D | Date and Place of Expiry | Final deadline & country for docs | Must expire in Bangladesh (Beneficiary country) |
| 50 | Applicant | Buyer's full legal name & address | Must match the buyer Purchase Order entity |
| 59 | Beneficiary | Factory's full legal name & address | Must match bank account and export trade license 100% |
| 32B | Currency Code & Amount | Total financial value of credit | Must cover 100% of order value (Qty × Unit Price) |
| 39A | Percentage Credit Amount Tolerance | Quantity/value tolerance (+/- %) | Standard is +/- 5% for apparel knitwear bulk runs |
| 44C | Latest Date of Shipment | Final on-board Bill of Lading date | Must allow sufficient buffer from factory ex-factory date |
| 44E / 44F | Port of Loading / Discharge | Loading and destination ports | POL: Chattogram / POD: Buyer destination port |
| 43P / 43T | Partial Shipments / Transshipment | Allowed or Prohibited | Partial shipments allowed; transshipment allowed |
| 45A | Description of Goods | Garment style, fabric, quantity | Must match PO & PI descriptions without conflicting specs |
| 46A | Documents Required | Master list of shipping documents | Invoices, B/L, Packing Lists, COO, Inspection Certs |
| 47A | Additional Conditions | Special clauses, certifications | Must be audited for unachievable "soft clauses" |
| 48 | Period for Presentation | Days allowed to submit documents | Standard is 21 days from Bill of Lading date |
10. L/C Amount & Currency
Field 32B specifies the currency and maximum monetary limit the issuing bank will pay.
Practical Calculation Example 1 (Full Value Match):
- Buyer PO Terms: 50,000 pcs Polo Shirts @ USD 4.50 / pc FOB Chattogram = USD 225,000.00
- Master L/C Field 32B:
USD 225,000.00 - Audit Finding: 100% Exact Match.
Practical Calculation Example 2 (Financial Deficit Variance):
- Buyer PO Terms: 60,000 pcs Denim Trousers @ USD 5.00 / pc = USD 300,000.00
- Master L/C Field 32B:
USD 285,000.00 - Variance Calculation: Value Variance = L/C Amount - PO Amount = 285,000 - 300,000 = -USD 15,000.00 (-5.0%)
- Commercial Action: The buyer opened the L/C for $15,000 less than the contracted order value. The Commercial Executive must halt fabric cutting and request an immediate SWIFT MT707 L/C amendment increasing Field 32B to USD 300,000.00 before production proceeds.
11. Expiry Date & Place of Expiry (Field 31D)
Field 31D stipulates two critical parameters:
- The Expiry Date: The absolute final calendar day on which shipping documents can be presented to the bank. Any document presented after this date is void.
- The Place of Expiry: The geographical location where documents must be presented.
CRITICAL AUDIT RULE: PLACE OF EXPIRY
12. Latest Shipment Date (Field 44C)
Field 44C dictates the final acceptable date stamped on the ocean carrier's On-Board Bill of Lading (B/L) or air freight Air Waybill (AWB).
- Hard Deadline: If Field 44C is 15-Nov-2026, and the vessel departs on 16-Nov-2026, the B/L is late shipped. The negotiating bank will immediately flag a fatal discrepancy under UCP 600 Article 14, refusing payment.
- Buffer Rule: The factory Ex-Factory date (when goods leave Gazipur/Narayanganj) must be scheduled at least 3 to 5 days before Field 44C to accommodate inland transit to Chattogram port, customs processing, and container loading.
13. Presentation Period & The 21-Day Rule (Field 48)
Field 48 sets the timeframe within which documents must be submitted to the bank after the goods are shipped.
ICC UCP 600 Article 14(c) Default Rule:
- If the L/C specifies a presentation period (e.g., "Documents must be presented within 15 days after date of shipment"), that period strictly applies.
- If the L/C is silent and does NOT state a presentation period, UCP 600 Article 14(c) dictates that documents must be presented no later than 21 calendar days after the date of shipment, but in any event no later than the expiry date of the credit.
Final Presentation Deadline = (B/L Date + 21 days, L/C Expiry Date)
Operational Example: If B/L Date is 10-Nov-2026, the 21-day presentation window ends on 01-Dec-2026. However, if the L/C Expiry Date is 25-Nov-2026, documents presented on 26-Nov-2026 are stale and rejected, because the L/C expired!
14. Goods Description (Field 45A)
Field 45A describes the merchandise being exported. Under UCP 600 Article 18(c), the description of goods in the Commercial Invoice must correspond exactly with the description in the credit.
- PO Description:
100% Cotton Men's Knitted Polo Shirt Style #PL-409 - L/C Field 45A:
100% Cotton Men's Knitted Polo Shirt Style #PL-409 - Commercial Invoice: Must use the exact same wording character-for-character.
15. Required Documents (Field 46A)
Field 46A lists the complete documentary set the factory must produce and present to obtain payment:
TYPICAL FIELD 46A DOCUMENTARY PACKAGE
| # | Document Name | Standard Quantity & Attestation Requirements |
|---|---|---|
| 01 02 03 04 05 06 | Signed Commercial Invoice Detailed Packing List Full Set Clean On-Board Ocean Bills of Lading Certificate of Origin (COO) Inspection Certificate (PSI) Beneficiary Certificate | Original in 3 copies plus 3 signed copies Original in 3 copies showing carton breakdown 3/3 Original Bills of Lading endorsed to bank Issued by EPB / BGMEA / Chamber of Commerce Issued by buyer's nominated agency (e.g., SGS) Confirming non-negotiable docs couriered |
16. Payment Terms: Sight L/C vs Usance L/C
Payment timing determines when the factory realizes export cash flow:
1. Sight L/C (Immediate Payment):
- Under a Sight L/C, the issuing bank must examine documents within 5 banking days (UCP 600 Art 14b) and remit payment immediately upon confirming document compliance.
- Best for Factory Working Capital: Minimizes factory borrowing and interest costs.
2. Usance L/C / Deferred Payment L/C (Time Drafts):
- Under a Usance L/C, the bank accepts the documents but defers payment for a contracted period—such as 60, 90, or 120 days from the Bill of Lading date or from document acceptance.
- Financial Impact: The factory must arrange Bill Discounting (UPAS - Usance Payable at Sight or Export Bill Discounting) with their local bank to receive early cash, incurring financing interest charges.
17. Partial Shipments: Allowed vs Prohibited (Field 43P)
Field 43P indicates whether the factory is permitted to ship the total order in multiple split batches:
ALLOWED / PERMITTED:The factory can ship 20,000 pcs on Vessel A and 30,000 pcs on Vessel B.PROHIBITED / NOT ALLOWED:The entire 50,000 pcs must be loaded on a single vessel under a single Bill of Lading.
Commercial Risk: If a factory faces sewing delays and partial shipment is PROHIBITED, shipping even 100 pieces less than the full order constitutes an unauthorized partial shipment, triggering bank discrepancy rejection!
18. Transshipment: Allowed vs Prohibited (Field 43T)
Transshipment occurs when cargo is unloaded from one vessel and loaded onto another vessel during ocean transit (e.g., feeder vessel from Chattogram to Singapore, then mother vessel from Singapore to Rotterdam).
- In Bangladesh maritime logistics, almost 100% of container shipments require feeder-to-mother vessel transshipment at regional hub ports (Singapore, Colombo, Tanjung Pelepas, Port Klang).
- Audit Rule: Field 43T MUST ALWAYS BE ALLOWED. If the buyer's L/C mistakenly states
TRANSSHIPMENT: PROHIBITED, the factory will receive an automatic discrepancy on the ocean Bill of Lading!
19. Incoterms in Documentary Credits
The Incoterm quoted in Field 45A or Field 47A dictates freight payment wording on transport documents:
- FOB (Free On Board): Bill of Lading must state "Freight Collect" (ocean freight paid by buyer at destination).
- CFR (Cost & Freight) / CIF (Cost, Insurance & Freight): Bill of Lading must state "Freight Prepaid" (ocean freight paid by factory in Bangladesh before B/L issuance).
20. The Document Hierarchy: PO vs PI vs Master L/C
The Purchase Order, Proforma Invoice, and Master L/C form an interconnected commercial triangle:
[ BUYER PURCHASE ORDER (PO) ] <======== Commercial Baseline ========> [ PROFORMA INVOICE (PI) ]
│ │
└─────────────────────> [ MASTER L/C (SWIFT MT700) ] <────────────────┘
│
▼
[ Independent Bank Undertaking Governed by UCP 600 ]
│
▼
[ 100% Clean Shipping Documents Prepared for Bank ]| Dimension | Purchase Order (PO) | Proforma Invoice (PI) | Master Letter of Credit (L/C) |
|---|---|---|---|
| Issuing Entity | Buyer | Seller / Factory | Buyer's Issuing Bank |
| Legal Nature | Procurement Contract | Binding Sales Offer | Independent Financial Guarantee |
| Enforcement | Commercial Contract Law | Commercial Contract Law | International Banking Law (UCP 600) |
| Bank Standing | Banks ignore PO terms | Banks ignore PI terms | Banks are 100% bound by L/C terms |
21. The L/C Amendment Process (SWIFT MT707)
Whenever an L/C contains an error, unfeasible date, or mismatched value, it must be formally amended.
How an Amendment Operates:
- Commercial Executive identifies discrepancies during pre-shipment audit.
- Factory sends a formal written Amendment Request to the buyer.
- Buyer instructs their issuing bank to transmit a SWIFT MT707 (Amendment to Documentary Credit).
- Advising bank delivers the MT707 copy to the factory.
- The factory formally reviews and accepts the amendment.
Golden Rule: Never ship goods relying on a buyer's email promise that "we will accept the discrepancy later." Always wait for the official SWIFT MT707 amendment!
22. Commercial Executive's Pre-Shipment L/C Audit Checkpoints
Before cutting fabric or booking shipping containers, execute this 10-point checkpoint verification:
COMMERCIAL EXECUTIVE PRE-SHIPMENT L/C CHECKLIST
| # | Checkpoint Field | What to Verify | Potential Risk if Overlooked |
|---|---|---|---|
| 01 02 03 04 05 06 07 08 09 10 | Beneficiary (F59) Credit Amount (F32B) Expiry Date (F31D) Expiry Place (F31D) Ship Date (F44C) Transshipment (F43T) Partial Ship (F43P) Port of Load (F44E) Documents (F46A) Special Cond (F47A) | Exact factory legal name, spelling, and street address Sufficient to cover 100% of order quantity x price Allows at least 15-21 days buffer after ship date Must state "IN BANGLADESH" (Beneficiary country) Allows sufficient factory production and port transit Must be "ALLOWED" for feeder vessel transit Must match factory production capacity strategy Must state Chattogram (or Dhaka Airport if air) All requested certificates are obtainable by factory No restrictive soft clauses or third-party vetoes | Bank rejection of invoices/BL Financial shortfall on payment L/C expires before presentation Documents lost/delayed in flight Late shipment payment refusal Incurable Bill of Lading error Split shipment penalty Port mismatch discrepancy Missing document dishonor Buyer blocks payment release |
23. Comprehensive Factory Case Study: Apex Garments Ltd.
Profile:
- Exporter: Apex Garments Ltd. (Gazipur, Bangladesh)
- Buyer: EuroFashion S.A. (Madrid, Spain)
- Order Item: 50,000 Men's Cotton Polo Shirts @ USD 4.50 / pc FOB Chattogram
- Total Order Value: USD 225,000.00
The Commercial Challenge:
Apex Garments received the SWIFT MT700 advising copy from Eastern Bank PLC. The Junior Commercial Executive audited the document against PO #EF-9088 and discovered two critical defects:
- Field 59 (Beneficiary): Stated
"Apex Garment Ltd., Plot 12, Gazipur"(Missing the plural letter "s" and missing the industrial area designation from the factory's registered ERC certificate). - Field 44C (Latest Shipment Date): Stated
25-OCT-2026. However, the approved PO Ex-Factory date was05-NOV-2026with vessel sailing on10-NOV-2026.
Core Commercial Concept
Commercial Execution & Financial Outcome:
The Commercial Manager withheld production cutting until Banco Santander transmitted SWIFT MT707 correcting Field 59 and extending Field 44C to 15-NOV-2026 and Field 31D (Expiry) to 05-DEC-2026. Goods sailed smoothly on 10-Nov-2026. Clean documents were negotiated at Eastern Bank PLC on 18-Nov-2026, and full proceeds of USD 225,000.00 were realized with zero bank discrepancy fees.
24. Case Study — Basic L/C Problems & Resolution Scenarios
| # | Discrepancy Scenario | Root Cause | Risk Under UCP 600 | Required Commercial Resolution |
|---|---|---|---|---|
| 01 | Amount Deficit | L/C opened for $190,000 on a $200,000 order | Under-invoicing or math error | Buyer bank refuses docs for overdrawn credit |
| 02 | Beneficiary Name Typo | "Tex Modern Ltd" instead of "Textile Modern Ltd" | Clerical error at issuing bank | Negotiating bank cannot endorse docs for wrong entity |
| 03 | Unrealistic Ship Date | Ship date is 10 days before production finishes | Buyer merchandiser entered wrong date | Late shipment discrepancy; irreversible document failure |
| 04 | Incorrect Destination Port | L/C states Rotterdam; PO requested Hamburg | Buyer logistics re-routed cargo | Bill of Lading conflicts with L/C Field 44F |
| 05 | Unobtainable Document | Demands "Factory Certificate signed by Buyer CEO" | Restrictive soft clause condition | Exporter cannot obtain foreign CEO physical signature |
| 06 | Payment Term Conflict | L/C states 90-Day Usance; PO agreed Sight L/C | Buyer seeks unapproved supplier credit | Factory working capital frozen for 3 months |
25. The Commercial Department's Operational Role
The Commercial Executive manages the Master L/C across four distinct operational phases:
[ Phase 1: Pre-Production & Inward L/C Audit ]
- Receive SWIFT MT700 from Advising Bank.
- Execute 20-point audit against PO & PI.
- Obtain necessary SWIFT MT707 amendments.
- Distribute approved L/C to Merchandising and Planning.
│
▼
[ Phase 2: Raw Material Procurement & Production Support ]
- Open Back-to-Back (BTB) L/Cs utilizing Master L/C collateral.
- Submit Master L/C copy for Utilization Declaration (UD) issuance.
- Track factory production milestones against Field 44C Latest Ship Date.
│
▼
[ Phase 3: Post-Shipment Logistics & Document Preparation ]
- Obtain clean On-Board Bills of Lading from shipping line.
- Generate Commercial Invoices and Packing Lists conforming 100% to Field 45A.
- Procure required Certificate of Origin (COO) and Inspection Certificates.
│
▼
[ Phase 4: Bank Presentation & Export Realization ]
- Submit complete documentary package to Negotiating Bank within Field 48 window.
- Track document courier transit to foreign Issuing Bank.
- Realize foreign currency export proceeds and retire Back-to-Back liabilities.26. 15 Common Commercial Mistakes to Avoid
- Accepting Verbal Commitments: Cutting fabric or shipping goods based on an unauthenticated email or verbal promise without receiving the SWIFT MT700.
- Ignoring Typographical Errors in Beneficiary Name: Assuming a single missing letter in company name will be overlooked by bank examiners.
- Overlooking Country of Expiry: Accepting an L/C expiring in the buyer's country rather than in Bangladesh.
- Failing to Audit Transshipment Clauses: Allowing
TRANSSHIPMENT: PROHIBITEDwhen ocean cargo must transfer at feeder ports. - Ignoring Insufficient Presentation Periods: Accepting a 7-day presentation window when obtaining original Bills of Lading takes 10 days.
- Mismatched Goods Description: Adding unsolicited marketing words in Commercial Invoices that do not appear in Field 45A.
- Neglecting L/C Amount Tolerances: Over-shipping beyond the +/- 5% tolerance in Field 39A, causing an overdrawn credit discrepancy.
- Shipping Past Latest Shipment Date: Handing cargo to the carrier one day after Field 44C without an approved amendment.
- Confusing Sight L/C with Usance L/C: Proceeding under deferred payment terms without factoring in bank interest discounting costs.
- Overlooking Restrictive Inspection Clauses: Failing to verify who must sign the Pre-Shipment Inspection Certificate.
- Failing to Track L/C Amendments: Operating on outdated L/C terms after a SWIFT MT707 amendment was received.
- Delayed Document Submission: Presenting documents on day 22 after shipment when the L/C allowed 21 days.
- Inconsistent Document Dates: Dating the Commercial Invoice or Certificate of Origin prior to the L/C issuance date where prohibited.
- Omitting Required Copies: Presenting 2 invoice copies when Field 46A explicitly mandated 3 originals and 3 copies.
- Failing to Maintain Document Archives: Discarding transmission receipts and bank negotiation schedules after export realization.
27. Important Commercial & Trade Terminology
- Letter of Credit (L/C): A formal written undertaking by a bank guaranteeing payment to a seller against strictly compliant shipping documents. Practical Note: Substitutes bank credit for buyer credit.
- Applicant: The buyer or importing entity who applies to the issuing bank to open the Letter of Credit. Practical Note: Establishes the initial credit parameters and reimburses the bank.
- Beneficiary: The seller or manufacturing factory in whose favor the credit is opened and who receives payment. Practical Note: Must ensure its corporate name matches bank records 100%.
- Issuing Bank: The foreign financial institution that opens the L/C and assumes the irrevocable legal obligation to pay. Practical Note: Examines presented documents under UCP 600.
- Advising Bank: The local bank in the exporter's country that authenticates and delivers the L/C to the beneficiary. Practical Note: Serves as the primary operational bank for the exporter.
- SWIFT MT700: The standardized international electronic banking message format used to issue a documentary credit. Practical Note: Contains all numbered fields governing the export transaction.
- SWIFT MT707: The standard electronic banking message format used to transmit an official amendment to an existing L/C. Practical Note: Required whenever order quantity, price, or shipment date changes.
- Latest Shipment Date (Field 44C): The final permissible calendar date stamped on the carrier's Bill of Lading. Practical Note: Missing this date constitutes an incurable bank discrepancy.
- Presentation Period (Field 48): The contracted number of days following the Bill of Lading date within which documents must reach the bank. Practical Note: Default is 21 calendar days under UCP 600 Art 14(c).
- UCP 600: The Uniform Customs and Practice for Documentary Credits, 2007 Revision, ICC Publication No. 600. Practical Note: The global legal framework governing all international Letters of Credit.
28. Interview Preparation Questions & Model Answers
Q1: What is a Letter of Credit, and how does it protect a garment exporter?
Model Answer: A Letter of Credit is an independent, legally binding undertaking by an Issuing Bank guaranteeing payment to the Beneficiary (exporter) upon presentation of strictly conforming shipping documents. It protects the exporter by substituting the financial creditworthiness of a global bank for the commercial creditworthiness of the foreign buyer, eliminating payment default and insolvency risks.
Q2: Under UCP 600, do banks examine goods or documents?
Model Answer: Under UCP 600 Article 5, banks deal strictly with documents alone, and not with the goods, services, or performance to which the documents relate. If the paperwork complies 100% with the L/C terms on its face, the bank must honor payment regardless of external commercial disputes.
Q3: What is the difference between an Issuing Bank and an Advising Bank?
Model Answer: The Issuing Bank is the buyer's bank that opens the L/C and assumes full financial liability to pay the exporter. The Advising Bank is the exporter's local bank that verifies the authenticity of the SWIFT transmission and advises (delivers) the L/C to the factory, without assuming any payment liability of its own.
Q4: Why is it dangerous if an L/C expires in the buyer's country rather than Bangladesh?
Model Answer: If an L/C expires in the buyer's country, original documents must physically arrive at the foreign bank's counter before the expiry date. If international couriers are delayed by customs, weather, or flights, the credit expires while documents are in transit, leaving the factory with zero payment security.
Q5: What is the default presentation period under UCP 600 if Field 48 is omitted?
Model Answer: Under UCP 600 Article 14(c), if no presentation period is stipulated in the credit, the default period is 21 calendar days after the date of shipment (Bill of Lading date), but in any event no later than the expiry date of the credit.
Q6: What should a Commercial Executive do immediately upon receiving a SWIFT MT700 copy?
Model Answer: The executive must execute a comprehensive pre-shipment audit against the approved Buyer PO and PI: (1) Verify Beneficiary Name/Address spelling, (2) Check Credit Amount and Currency, (3) Confirm Latest Shipment and Expiry dates provide adequate buffer, (4) Ensure Transshipment is allowed, and (5) Audit Field 46A/47A for unachievable document conditions.
Q7: What is the difference between a Sight L/C and a Usance L/C?
Model Answer: Under a Sight L/C, the issuing bank must remit payment immediately upon receiving and verifying compliant documents (within 5 banking days). Under a Usance L/C, payment is deferred for an agreed period (e.g., 60, 90, 120 days from B/L date), requiring the factory to arrange bill discounting to access immediate liquidity.
Q8: Why must Field 43T (Transshipment) always be "ALLOWED" for garment exports from Bangladesh?
Model Answer: Bangladesh feeder vessels transport containers from Chattogram Port to deep-sea transshipment hubs (Singapore, Colombo, Tanjung Pelepas) where cargo is transferred to mother ocean vessels. This transfer constitutes transshipment on the ocean Bill of Lading. If Field 43T states "PROHIBITED", the B/L will contain an automatic discrepancy.
Q9: What is a SWIFT MT707, and when is it utilized?
Model Answer: SWIFT MT707 is the standard electronic banking message used to transmit formal amendments to an existing Letter of Credit. It is utilized whenever commercial terms—such as order quantity, total value, latest shipment date, expiry date, or product specifications—are modified after L/C issuance.
Q10: How does a Master L/C facilitate raw material procurement in Bangladesh?
Model Answer: A Master L/C serves as primary financial collateral against which commercial banks in Bangladesh open Back-to-Back (BTB) L/Cs to import raw materials (yarn, fabric, trims) and obtain bonded warehouse Utilization Declarations (UD) without paying upfront cash.
Q11: What is a "Confirmed L/C", and when should an exporter demand one?
Model Answer: A Confirmed L/C contains an independent, binding payment guarantee added by a first-class international bank (Confirming Bank) in addition to the issuing bank's undertaking. Exporters demand confirmation when dealing with buyers in high-risk countries facing political instability, currency shortages, or sovereign debt crises.
Q12: If a Buyer PO states Ex-Factory on 10-Nov-2026, what should the L/C Latest Shipment Date be?
Model Answer: The Latest Shipment Date (Field 44C) should be at least 15-Nov-2026 to 20-Nov-2026 (a 5 to 10-day buffer) to allow sufficient time for inland container trucking from factory to Chattogram port, customs physical examination, shipping bill passing, and container loading onto the feeder vessel.
29. Frequently Asked Questions (FAQs)
1. Can a buyer unilaterally cancel an Irrevocable Letter of Credit?
No. Under UCP 600 Article 10, an Irrevocable Letter of Credit cannot be amended or canceled without the explicit agreement of the Issuing Bank, the Confirming Bank (if any), and the Beneficiary (exporter).
2. What happens if there is a discrepancy between the L/C and shipping documents?
The issuing bank will issue a Notice of Refusal (discrepancy notice), hold payment, and charge a discrepancy fee ($80–$150). Payment is released only if the buyer accepts the discrepancy waiver or if the exporter corrects the paperwork before credit expiry.
3. Does an L/C guarantee that the garments are of good quality?
No. Banks deal strictly with documents, not goods. Quality assurance is maintained through pre-shipment inspection certificates issued by independent third-party agencies (SGS, Intertek, Bureau Veritas) stipulated in Field 46A.
4. How long does an issuing bank have to examine presented documents?
Under UCP 600 Article 14(b), the issuing bank, confirming bank, and nominated bank each have a maximum of 5 banking days following the day of presentation to examine documents and determine compliance.
5. What is the difference between a Master L/C and a Back-to-Back L/C?
A Master L/C is opened by the foreign buyer in favor of the garment factory for finished garments. A Back-to-Back L/C is opened by the garment factory in favor of raw material suppliers (fabric/trims mills) backed by the Master L/C as collateral.
6. Can an export factory ship goods before receiving the Master L/C?
Shipping before receiving an authenticated SWIFT MT700 is extremely risky. The factory loses all documentary credit payment security, converting the transaction into an unhedged open-account credit risk.
7. What is an EXP Form, and how does it relate to the Master L/C?
An EXP Form is a mandatory statutory export declaration issued by the exporter's authorized dealer bank under Bangladesh Bank regulations, certifying that export proceeds will be repatriated against a valid Master L/C or sales contract.
8. What is standard quantity tolerance in Field 39A?
The industry standard in garment manufacturing is +/- 5% in quantity and overall value, which accommodates fabric yield variations, shrinkage, and knitting/weaving batch overages.
9. Who pays bank L/C advising and negotiation charges?
Standard commercial practice dictates that issuing bank charges are paid by the Applicant (buyer), while advising, amendment, negotiation, and courier fees incurred in Bangladesh are paid by the Beneficiary (exporter), unless negotiated otherwise.
10. Can a Proforma Invoice replace a Master L/C?
No. A Proforma Invoice is simply a commercial price quotation and sales contract. It does not provide any bank payment guarantee. A Master L/C is an independent banking commitment that ensures guaranteed payment realization.
30. Key Takeaways & Summary Points
- Independent Bank Guarantee: A Letter of Credit is an independent legal undertaking by an Issuing Bank to pay the exporter against strictly conforming shipping documents, independent of the underlying sales contract.
- Documentary Nature (UCP 600): Banks deal exclusively in documents, not goods. 100% precision in spelling, numbers, dates, and certifications is mandatory.
- Core Parties: The transaction connects the Applicant (Buyer), Issuing Bank (Buyer's Bank), Beneficiary (Factory Exporter), and Advising/Nominated Bank (Factory's Bank).
- Critical Dates: Latest Shipment Date (Field 44C) and L/C Expiry Date (Field 31D) are non-negotiable hard deadlines.
- Place of Expiry: The credit must always expire in the Beneficiary's country (Bangladesh) to prevent documents from expiring in courier transit.
- Transshipment Clause: Field 43T must always be ALLOWED to accommodate ocean feeder vessel transshipment at regional transit ports.
- Presentation Window: Documents must be submitted within the period specified in Field 48 (or 21 days from B/L date under UCP 600 Art 14c), prior to credit expiry.
- Pre-Shipment Audit: Commercial Executives must cross-verify all 20 vital fields against the PO and PI before cutting fabric or booking shipping containers.

TABLE 1: Master Letter of Credit Primary Parties & Legal Obligations
| L/C Party | Who They Are in Garment Trade | Main Legal & Financial Role |
|---|---|---|
| Applicant | Foreign Buyer / Importer (e.g., H&M, Zara, Walmart) | Applies for L/C; provides collateral; reimburses issuing bank upon document release. |
| Issuing Bank | Buyer's Bank (e.g., BNP Paribas, HSBC Paris) | Issues L/C; assumes independent legal undertaking to pay beneficiary against compliant documents. |
| Beneficiary | Apparel Manufacturer / Exporter (e.g., Apex Apparels Ltd.) | Recipient of credit; manufactures garments; presents strictly compliant shipping documents. |
| Advising Bank | Exporter's Local Bank (e.g., Eastern Bank PLC, Dhaka) | Authenticates SWIFT MT700 message validity and advises (delivers) credit copy to factory. |

| Master Letter of Credit (L/C) | Buyer's Issuing Bank | Independent financial undertaking guaranteeing export payment | Governed by ICC UCP 600; legally binding on bank independent of underlying contracts. |
TABLE 4: Commercial Executive's Pre-Shipment L/C Audit Checkpoints
| Checkpoint Field | What to Verify | Possible Commercial & Financial Risk |
|---|---|---|
| Beneficiary Name (F59) | Exact factory legal title, spelling, and registered address | Bank document rejection and non-negotiation of export bills. |
| Credit Amount (F32B) | Exact mathematical match with PO quantity x unit price | Overdrawn credit discrepancy; unpaid financial balance. |
| Place of Expiry (F31D) | Must be 'IN BANGLADESH' (Seller's country) | Documents expire in courier transit to foreign destination. |
| Latest Ship Date (F44C) | Allows 3-5 days buffer after factory production finish | Late shipment discrepancy; immediate payment refusal under UCP 600. |

| Special Clauses (F47A) | Audit for restrictive soft clauses or third-party vetoes | Buyer blocks payment release after cargo departure. |
Practical Commercial Flow
Example 1: PO Quantity = 50,000 pcs @ USD 4.50/pc FOB Chattogram = USD 225,000.00. Master L/C Field 32B = USD 225,000.00 (100% matched). Example 2: PO Value = USD 300,000.00, but L/C is opened for USD 285,000.00 (a USD 15,000.00 or 5% deficit). Commercial must halt fabric cutting and request an immediate MT707 amendment before production proceeds.
Factory Real-Life Scenario
Scenario: Apex Garments Ltd. in Gazipur, Bangladesh received a Master L/C for 50,000 polo shirts (USD 225,000.00) from EuroFashion S.A., Spain. The commercial executive audited the advising copy and discovered two critical errors: (1) Field 59 listed the beneficiary as 'Apex Garment Ltd.' (missing the plural 's' and factory registered address), and (2) Field 44C listed Latest Shipment Date as 25-Oct-2026, while the approved PO Ex-Factory date was 05-Nov-2026.
Solution: The Commercial Executive immediately withheld Back-to-Back L/C opening, logged the discrepancies in the L/C Audit Register, and notified the Merchandising Lead. Commercial issued a formal SWIFT MT707 amendment request to EuroFashion S.A. to correct the company name to 'Apex Apparels Ltd.' and extend the shipment date to 15-Nov-2026 and expiry to 30-Nov-2026.
Impact: The issuing bank transmitted MT707 amendment within 48 hours. Apex Garments produced and shipped the 50,000 pieces on 10-Nov-2026, submitted clean documents to Eastern Bank PLC, and negotiated full export proceeds of USD 225,000.00 with zero bank discrepancy fees or delayed realization.
Commercial Officer Best Practice
Expert Commercial Tip: When auditing an incoming Master L/C, calculate the exact gap between Field 44C (Latest Shipment Date) and Field 31D (Expiry Date). This gap must equal at least 21 days (or match Field 48). If the shipment date is 15-Nov and expiry is 20-Nov, you only have 5 days to collect original Bills of Lading, prepare 6 sets of shipping documents, and submit them to your bank—an extreme operational risk that requires an immediate expiry extension amendment!
Top Beginner Mistakes to Avoid
- Cutting fabric or booking yarn before receiving an authenticated SWIFT MT700 transmission copy from the advising bank.
- Overlooking typographical errors in Field 59 (Beneficiary Name), resulting in bank rejection of commercial invoices.
- Accepting an L/C that expires in the buyer's country, risking expiry while documents are in international courier transit.
- Failing to ensure Field 43T (Transshipment) is 'ALLOWED', creating incurable discrepancies on feeder vessel Bills of Lading.
- Accepting an L/C amount in Field 32B that is lower than the contracted PO total value.
- Shipping cargo after the Field 44C Latest Shipment Date without securing a formal SWIFT MT707 amendment.
- Failing to notice an unachievable 7-day presentation period in Field 48, causing stale document discrepancies.
- Confusing a Sight L/C with a 90-Day Usance L/C, resulting in unplanned factory cash flow deficits and discounting charges.
- Adding unapproved marketing descriptions to commercial invoices that conflict with Field 45A wording.
- Failing to verify who must sign the Pre-Shipment Inspection Certificate in Field 46A.
- Allowing partial shipments when Field 43P is marked 'PROHIBITED', leading to payment rejection for split consignments.
- Neglecting to track incoming SWIFT MT707 amendments, causing factory staff to work from outdated L/C terms.
- Submitting documents to the bank on day 22 when the default 21-day presentation window had expired.
- Failing to provide the exact number of original and duplicate invoice copies stipulated in Field 46A.
- Discarding bank negotiation schedules and SWIFT transmission receipts after export payment realization.
