Letter of Credit (LC) Complete Guide for Indian Exporters and Importers 2026
Everything you need to know about LC — how it works, all types explained, the discrepancy problem that kills 70% of first presentations, RBI and FEMA 2026 rules, LC vs Bank Guarantee, and 12 practical tips every Indian exporter must follow before presenting documents.
Key Facts at a Glance
- Governing rules: UCPDC 600 (UCP 600) — ICC rules effective July 2007. Incorporated in LC text by reference. RBI and FEMA always override UCP 600.
- Discrepancy rate: Over 70% of first LC document presentations contain at least one discrepancy (ICC Global Survey). The most common cause of delayed payment for Indian exporters.
- Types of LC: Sight, Usance (Deferred), Confirmed, Transferable, Back-to-Back, Standby (SBLC), Revolving, Red Clause, Green Clause.
- FEMA 2026: RBI notified FEMA (Export & Import of Goods and Services) Regulations 2026, effective October 1, 2026. Significant changes to LC usance periods and advance payment rules.
- LC vs BG: LC protects the seller (payment guarantee). Bank Guarantee protects the buyer (performance guarantee). Fundamentally different instruments.
- SWIFT format: Import LCs are issued as SWIFT MT700 messages. The MT700 field 47A (Additional Conditions) contains the most trip-wire clauses for exporters.
What is a Letter of Credit? (Plain Language)
International trade has one fundamental problem: the buyer and seller do not trust each other. The seller fears the buyer will not pay after goods are shipped. The buyer fears the seller will take the money and not ship the goods. This is the oldest standoff in global commerce.
A Letter of Credit (LC), also called a Documentary Credit, solves this by inserting a trusted third party — a bank — into the middle of the transaction. The bank promises to pay the seller, but only if the seller presents the exact documents specified in the LC. The buyer does not need to trust the seller. The seller does not need to trust the buyer. Both trust the bank.
In simple terms: an LC is a bank’s written commitment to pay the seller a specific amount, within a specific time, provided the seller presents documents that strictly comply with the LC terms.
How a Letter of Credit Works: Step by Step
Buyer and seller sign the sales contract
The commercial contract specifies that payment will be by LC. It defines the LC type (sight/usance), currency, amount, shipment terms (Incoterms), latest shipment date, expiry date, and which documents the seller must present to get paid.
Buyer applies to their bank (Issuing Bank) to open the LC
The buyer submits an LC application form to their bank with all terms. The bank checks the buyer’s credit limit, collects margin (typically 10–25% of LC value as cash margin or against existing limits), and charges LC opening commission (0.25%–0.5% per quarter).
Issuing Bank sends LC to Advising Bank via SWIFT
The LC is transmitted as a SWIFT MT700 message to the seller’s bank (Advising Bank) in the seller’s country. The Advising Bank verifies the authenticity of the SWIFT message and forwards the LC to the seller.
Seller reviews the LC carefully before producing or shipping
This is the most critical step that most exporters rush. The seller must read every clause of the LC and verify that all terms are achievable — shipment date, document requirements, Incoterms, port names, product description. If anything is wrong, request an amendment NOW, not after shipment.
Seller ships the goods and collects all required documents
After shipment, the seller prepares all documents specified in the LC — commercial invoice, Bill of Lading/Airway Bill, packing list, certificate of origin, insurance certificate, inspection certificate, etc. Every document must match every other document exactly.
Seller presents documents to Negotiating Bank within LC expiry
The seller submits all original documents to the negotiating bank (usually their own bank) within the LC validity period AND within the document presentation period (typically 21 days from shipment date, or as specified in the LC). Late presentation = discrepancy.
Bank examines documents (maximum 5 banking days under UCP 600)
The negotiating bank has a maximum of 5 banking days to examine the documents. Under UCP 600 Article 14, documents are examined on their face. If compliant, the bank pays or accepts the draft. If discrepant, the bank issues a notice of refusal within 5 banking days.
Payment is made (sight) or accepted for future payment (usance)
For Sight LC: payment is made immediately upon compliant document presentation. For Usance LC: the issuing bank accepts the draft and commits to pay on the due date (e.g., 60 days, 90 days, 180 days from B/L date). The seller may discount the accepted draft to get immediate funds.
Issuing bank reimburses negotiating bank and releases documents to buyer
The Issuing Bank reimburses the Negotiating Bank, then releases the original Bill of Lading (or other transport documents) to the buyer so they can take delivery of the goods from the shipping line.

Types of Letter of Credit — All Types Explained
Based on Payment Timing
Sight LC (At Sight LC)
Payment is made immediately (within 5 banking days) upon presentation of compliant documents to the nominated bank. Best for exporters — they get paid fast. Common in commodity and raw material trade. Indian exporters should prefer Sight LC wherever possible.
Usance LC (Deferred Payment LC)
Payment is deferred to a future date — typically 30, 60, 90, or 180 days after the Bill of Lading date (or sight). The buyer gets credit period to sell goods before paying. The seller can discount the accepted usance draft at their bank for immediate funds. Under FEMA 2026, usance for gold import is relaxed beyond the earlier 90-day cap.
Confirmed LC
A second bank (Confirming Bank, usually in the seller’s country) adds its own irrevocable payment undertaking to the Issuing Bank’s commitment. Essential when the Issuing Bank or the buyer’s country carries high risk. If the Issuing Bank defaults, the Confirming Bank pays. Costs more (0.5%–2% p.a. extra) but gives exporters double protection.
Transferable LC
The beneficiary (first seller / trader) can transfer the LC partially or wholly to a second beneficiary (actual manufacturer/supplier). The second beneficiary cannot transfer further. Useful for trading houses, merchants, and intermediaries who source from manufacturers. Must state “Transferable” explicitly in the LC.
Back-to-Back LC
The beneficiary uses the original LC as collateral to open a new (second) LC in favour of their own supplier. Unlike a Transferable LC, the original buyer does not need to know the actual supplier. Two separate LCs exist. Common in Indian export trade where exporters procure from domestic suppliers or third countries before re-exporting.
Standby LC (SBLC)
A payment of last resort. The SBLC is called (drawn) only if the applicant fails to fulfil their obligation — similar to a bank guarantee in function. Widely used in the USA (where bank guarantees are legally restricted). Under FEMA 2026, SBLCs may be required for large import advances beyond the AD bank determined threshold.
Revolving LC
After each drawing (payment), the LC reinstates automatically (either by time or by value) up to the original amount for a specified period. Ideal for buyers and sellers with ongoing, repetitive supply arrangements. Eliminates the need to open a fresh LC for every shipment. Two types: cumulative (unused balance carries forward) and non-cumulative.
Red Clause LC
A clause (historically typed in red ink) that allows the beneficiary to receive an advance payment before shipment — to buy raw material, produce, or pack goods. The advance is deducted from the final LC amount. Risk lies with the Issuing Bank and ultimately the buyer if the seller fails to ship.
Other Classification: Inland LC vs Foreign LC
An Inland LC is opened for domestic transactions between a buyer and seller within India. It follows RBI domestic guidelines and is governed by the Indian Contract Act. An Foreign LC (Import/Export LC) is for cross-border transactions and is governed by UCP 600 and FEMA/RBI regulations.
UCPDC 600 (UCP 600): What It Means in Practice
The Uniform Customs and Practice for Documentary Credits, 600th revision (UCP 600) is a set of 39 articles published by the International Chamber of Commerce (ICC) that governs how banks, buyers, and sellers deal with documentary credits worldwide. It came into effect on July 1, 2007, and applies to all LCs that incorporate it by reference — which virtually all international LCs do.
UCP 600 is not a law. It is a private set of rules that become legally binding only when written into the LC text. However, in India, RBI and FEMA regulations always take precedence over UCP 600 in case of any conflict.
| UCP 600 Article | What It Says | Practical Impact |
|---|---|---|
| Article 5 | Banks deal with documents, not goods | Bank pays if documents comply, even if actual goods are defective. Document accuracy is everything. |
| Article 14 | Standard for examination of documents; 5 banking day rule | Banks have maximum 5 banking days to examine and accept or reject documents. After 5 days, they cannot claim discrepancy. |
| Article 16 | Discrepant documents, notice of refusal | Bank must issue notice of refusal within 5 banking days. Notice must state ALL discrepancies in one communication — bank cannot come back with additional discrepancies later. |
| Article 20 | Bill of Lading rules | B/L must show carrier name, port of loading, port of discharge, date of shipment. Shipped on board notation required. “Clean” B/L required (no clauses about defective condition of goods). |
| Article 28 | Insurance document rules | Insurance must cover at minimum 110% of CIF value. Date of insurance must be no later than date of shipment. All risks cover required unless LC specifies otherwise. |
| Article 29 | Extension of expiry date or last day for presentation | If LC expiry falls on a bank holiday, expiry is extended to next banking day. But shipment date is never extended. |
| Article 31 | Partial drawings or shipments | Permitted unless LC prohibits them. Each partial presentation is treated as a separate LC utilization. |
Documents Typically Required Under an LC
The exact documents are specified in the LC. Typically required in Indian export trade:
| Document | Purpose | Common Discrepancy |
|---|---|---|
| Commercial Invoice | Shows goods description, quantity, unit price, total value, parties | Description not exactly matching LC field 45A; price higher than LC amount; missing terms like “FOB” or “CIF” |
| Bill of Lading (B/L) | Title document for goods; proves shipment by sea | Not marked “Shipped on Board”; issued to wrong consignee; port of loading/discharge mismatch; not clean; not signed by carrier |
| Airway Bill (AWB) | Title document for air shipments | Consignee not as per LC; flight date after latest shipment date |
| Packing List | Details of packages, weights, dimensions | Quantities not matching invoice; description wording different from LC |
| Certificate of Origin (COO) | Proves goods were manufactured in specified country | Issued by wrong authority; country of origin not matching; late issuance date |
| Insurance Certificate/Policy | Covers goods in transit (CIF shipments) | Coverage less than 110% of CIF; dated after shipment; wrong risks covered; not endorsed |
| Inspection Certificate | Pre-shipment quality verification (if required by LC) | Issued by wrong inspection agency; not before shipment date; goods description mismatch |
| Draft/Bill of Exchange | Financial instrument demanding payment | Drawn on wrong bank; tenor not matching LC; amount differs from invoice |
| Beneficiary Certificate | Self-declaration by seller (if required by LC) | Wording not exactly as per LC; missing signature; not dated |
The Discrepancy Problem: Why 70% of LC Presentations Fail First Time
This is the section that will save Indian exporters lakhs of rupees. The ICC estimates that over 70% of first LC document presentations contain at least one discrepancy. When a discrepancy is found, the bank refuses to pay. The exporter must then either: (1) correct and resubmit documents, (2) request the buyer to issue a waiver of discrepancy, or (3) request the issuing bank to accept documents on approval basis.
During this time — which can take 15 to 45 days — the exporter has shipped goods but received no money. Worse, the buyer may use the discrepancy as leverage to renegotiate price, especially when commodity prices have fallen since the contract was signed.
Top 10 Discrepancies That Kill Indian Exporter Payments
UCP 600 requires documents to be presented within 21 days of shipment (or as specified in LC), and before LC expiry. Missing either deadline is a discrepancy. Most common reason: exporter waits for all documents to arrive from various parties and misses the 21-day window.
The description of goods on the commercial invoice must match the description in LC Field 45A word for word. If LC says “Basmati Rice Grade A Long Grain” and your invoice says “Premium Basmati Rice” — discrepancy. Other documents (packing list, B/L) may use general terms, but the invoice cannot vary from the LC description.
UCP 600 requires a “Shipped on Board” notation with date. A “Received for Shipment” B/L is not acceptable unless the LC specifically allows it. The on-board date must be on or before the latest shipment date in the LC.
All documents must be consistent with each other. If the invoice shows 500 MT but the packing list shows 498 MT — discrepancy. If the B/L shows Port of Loading as “Mumbai” and the LC says “Nhava Sheva” — discrepancy (even though Nhava Sheva is the port inside JNPT, Mumbai). Banks take a literal approach.
The invoice amount, draft amount, and any partial drawing must not exceed the available LC balance. Exceeding by even one US dollar is a discrepancy. Note: freight, insurance, or incidental charges added to the invoice that push it over the LC value is a common trap.
For CIF shipments, insurance must cover minimum 110% of the CIF invoice value. Insurance certificate date cannot be later than B/L date. If the LC requires “All Risks” cover but the certificate shows “ICC (C)” (which is limited cover) — discrepancy. Insurance must be in the same currency as the LC.
If the LC specifies latest shipment date as 30 September and your B/L is dated 1 October — discrepancy, no exceptions. Exporters often commit to shipment dates they cannot meet because of cargo readiness, booking availability, or customs clearance delays. Always build buffer time.
The B/L consignee must match exactly what the LC specifies. If LC says “To Order of XYZ Bank” and B/L says “To Order of ABC Imports Ltd” — major discrepancy. The notify party name/address must also match exactly including telephone numbers if specified in the LC.
If the LC requires a beneficiary certificate but you did not submit it, that is a discrepancy. If the LC requires 3 originals + 2 copies of the commercial invoice and you submit 2 originals + 3 copies — discrepancy. Count the exact number of originals and copies required for each document.
SWIFT MT700 Field 47A contains special conditions added by the issuing bank or buyer. These are the most dangerous clauses because exporters often overlook them. Common hidden requirements: “All documents must be issued in English”, “B/L must show freight as prepaid”, “Third party documents not acceptable”, “Invoice must show buyer’s purchase order number”.
LC Amendment: When and How to Request One
An amendment is a modification to the original LC terms. It requires the consent of all parties — the applicant (buyer), the issuing bank, and the beneficiary. Once all parties agree, the amendment is transmitted as a SWIFT MT707 message.
Request an amendment immediately if you notice any of these after receiving the LC: wrong shipment date (cannot meet it), wrong port of loading/discharge, wrong goods description, wrong Incoterms, wrong currency, required documents you cannot produce. Do not wait until after shipment.
LC vs Bank Guarantee: The Key Differences
| Feature | Letter of Credit (LC) | Bank Guarantee (BG) |
|---|---|---|
| Who it protects | Seller (Beneficiary) — payment assurance | Buyer — performance/non-performance cover |
| When bank pays | When seller presents compliant documents | When buyer makes a claim of seller’s default |
| Bank’s role | Primary obligor — bank pays directly | Secondary obligor — bank pays only if applicant defaults |
| Document requirement | Yes — strictly document-based payment | Minimal — usually just a written claim/demand |
| UCP 600 applicability | Yes — UCP 600 governs | No — ISP98 or URDG 758 governs SBLCs/BGs |
| Common use in India | Import/export payments, trade transactions | Tender bids, government projects, performance bonds, advance payment security |
| Risk borne by | Buyer (must pay even if goods are defective — separate claim) | Seller (must perform to avoid BG invocation) |
| LC/BG charges India | 0.25%–0.5% per quarter of LC value | 0.25%–1% per annum of BG value |
LC Charges in India: What Banks Actually Charge
| Charge Type | Who Pays | Typical Rate (India) | When Charged |
|---|---|---|---|
| LC Opening / Issuance Commission | Buyer (Applicant) | 0.25%–0.5% per quarter of LC value | At time of LC opening |
| Advising Charges | Seller (Beneficiary) | Rs.1,500–Rs.3,500 per LC | When LC is received and forwarded to beneficiary |
| Amendment Charges | Buyer or Seller (as agreed) | Rs.2,000–Rs.5,000 per amendment (issuing bank) + advising charges | Per amendment processed |
| Confirmation Charges | Buyer or Seller (as agreed in sales contract) | 0.5%–2% p.a. of LC value (varies by country risk) | When confirming bank adds its undertaking |
| Negotiation / Document Handling Charges | Seller (Beneficiary) | Rs.1,500–Rs.4,000 per set of documents | When documents are submitted for negotiation |
| Discrepancy Fee | Seller (Beneficiary) | USD 50–USD 150 per discrepancy or per presentation | When discrepant documents are submitted |
| Reimbursement / Swift Charges | Buyer | Rs.500–Rs.1,500 per SWIFT message | Each bank-to-bank SWIFT communication |
| Usance Interest (if applicable) | Buyer | SOFR / LIBOR replacement rate + spread | For usance LCs, on the deferred amount |
RBI and FEMA 2026 Rules on Letter of Credit
The RBI notified the Foreign Exchange Management (Export and Import of Goods and Services) Regulations, 2026 in March 2026, which came into effect on October 1, 2026. This is the most significant overhaul of India’s trade finance regulatory framework in a decade. Here are the key changes affecting LC transactions:
| Rule / Change | Earlier Position | FEMA 2026 Position |
|---|---|---|
| LC for future exporters with unrealized proceeds | Exporters with overdue export proceeds could continue exporting on open account | If export proceeds unrealized beyond 1 year from due date, future exports only allowed against full advance payment OR irrevocable LC |
| Import advance payment threshold | Advance payments up to USD 2,00,000 without SBLC/BG | USD 2,00,000 cap replaced by AD bank determined threshold. Beyond threshold, SBLC or BG required |
| Gold import usance period | Maximum 90 days usance for gold import LC | 90-day restriction relaxed; AD bank to determine based on guidelines |
| Failed import advance recovery | Case-by-case treatment | If advance import payment fails and IDPMS entry is unmarked, future import advances only against irrevocable LC or BG |
| AD Bank authority | Many decisions required RBI approval | AD Banks empowered to grant extensions for both export and import timelines without referring to RBI |
12 Practical Tips for Indian Exporters: Get Paid Without Discrepancy
Pre-Shipment LC Checklist — Do This Before You Produce or Ship
- Read every field of the LC — especially Field 45A (goods description), Field 46A (required documents), Field 47A (additional conditions), and Field 48 (presentation period).
- Check if latest shipment date is achievable. If not, request amendment immediately.
- Verify port of loading and discharge match your actual shipping route.
- Confirm the Incoterms in the LC match your sales contract (FOB, CIF, CFR, etc.).
- Check which party pays freight and ensure the B/L endorsement (“Freight Prepaid” or “Freight Collect”) matches LC requirements.
- Identify all documents required and verify you can procure each one — including any third-party certificates (inspection, phytosanitary, fumigation, etc.).
- Check Field 47A line by line for hidden conditions that your standard documents may not satisfy.
- Confirm the LC allows partial shipments if you plan to ship in multiple lots.
- Confirm the LC allows transhipment if your shipping route requires it.
- Verify the LC currency and amount are exactly what was agreed in the sales contract.
More Practical Tips
- Never rush the B/L. Confirm with your shipping agent that the B/L will show the exact port of loading as in the LC (e.g., “Jawaharlal Nehru Port, Navi Mumbai” vs “Mumbai” vs “Nhava Sheva” — these are treated as different ports by banks).
- Prepare all documents together. Check them against each other before submission. Quantities, descriptions, marks and numbers must match across all documents.
- Submit documents early. If the presentation period is 21 days, submit by day 14. This gives time to correct any discrepancy the bank points out.
- Always insist on payment terms in writing before production. An LC protects you only if you can comply with its terms. An LC with impossible terms protects no one.
