ISBP 745 Article B B3: Invoice Currency Must Match the Credit

Introduction

The currency of the commercial invoice is one of the most closely examined data points in a documentary credit presentation. ISBP 745 Paragraph B3 establishes that the invoice currency must match the currency of the credit. This rule ensures consistency across all documents and prevents confusion about the transaction's value. A mismatched currency on the invoice is one of the simplest discrepancies to identify and one of the easiest to prevent. This guide explains how B3 works, why currency mismatches occur, and how to ensure your invoice carries the correct currency.

Failure Modes

1. Invoice in USD when credit is in EUR. The credit is denominated in EUR, but the invoice shows amounts in USD. The bank finds this a discrepancy under Article 14(d).

2. Mixed currencies on the invoice. The invoice shows the goods value in EUR but the freight and insurance charges in USD. The bank expects all amounts to be in the credit's currency.

3. Currency code mismatch. The credit uses "EUR" but the invoice writes "Euro" or uses the symbol "€" without the ISO code. Some banks flag this as a discrepancy.

4. Invoice in the contract currency, not the credit currency. The underlying contract is denominated in USD, but the credit is in GBP. The seller issues the invoice in USD (matching the contract) instead of GBP (matching the credit).

5. Currency conversion on the invoice. The invoice shows the amount in both USD and EUR, with a conversion rate. The bank expects only the credit's currency, not a dual-currency presentation.

Resolution Steps

1. Identify the credit's currency. Determine the exact currency of the credit from the credit text. Note the ISO code (USD, EUR, GBP, JPY, etc.) and the exact amount.

2. Issue the invoice in the credit's currency. All amounts on the invoice—unit price, total value, freight, insurance—must be in the credit's currency. Do not use the contract currency if it differs from the credit currency.

3. Use the ISO currency code. Write the currency as "EUR," "USD," "GBP," etc. Do not use symbols or abbreviations that may be ambiguous.

4. Confirm the exchange rate if applicable. If the contract is in a different currency, use the exchange rate at the time of invoicing to convert to the credit's currency. Record the exchange rate on the invoice for transparency.

5. Check for currency clauses in the credit. Some credits specify "currency of the country of the beneficiary" or "equivalent in [currency]." Read these clauses carefully and comply with the exact currency requirement.

6. Verify the invoice amount matches the credit amount. The invoice total must match the credit amount (subject to tolerances under UCP 600 Article 30). A mismatched amount in the correct currency is still a discrepancy.

7. Coordinate with the accounting department. Ensure the invoicing team understands the credit's currency requirement and does not default to the company's home currency or the contract currency.

8. Review the invoice before submission. Check the currency on the invoice against the credit one final time before presenting to the bank. This simple check prevents one of the most common discrepancies.

Conclusion

ISBP 745 B3 requires the invoice currency to match the credit currency. This is one of the simplest rules to comply with and one of the most commonly violated. A pre-submission review—checking the invoice currency against the credit—eliminates this discrepancy entirely.

FAQ

Q1: Can the invoice show amounts in more than one currency?
Only if the credit expressly permits it. If the credit is denominated in EUR, the invoice should show all amounts in EUR. A dual-currency invoice may be flagged as a discrepancy.

Q2: What if the credit says "currency of the country of the seller"?
This means the invoice must be in the seller's home country currency. If the seller is in Japan, the invoice must be in JPY. Confirm the credit's intent and comply.

Q3: Can the bank accept an invoice in a different currency if the amount is equivalent?
No. UCP 600 and ISBP 745 are strict on currency matching. An invoice in a different currency—even if the amount is equivalent—is a discrepancy.

Q4: What if the credit allows a tolerance on the amount?
UCP 600 Article 30(a) allows a ±10% tolerance for "about" or "approximately." This tolerance applies to the amount, not the currency. The currency must still match exactly.

Q5: Does this rule apply to other documents?
Yes. All documents presented under the credit must be in the credit's currency or comply with the credit's currency requirements. The invoice is the most common source of currency discrepancies, but the rule applies to all documents.
