UCP 600 Article 6: Availability, Expiry Date, and Amendment Implications

Introduction

The expiry date of a documentary credit is the hard deadline for presentation. Miss it, and the bank is discharged from its undertaking. Article 6 of UCP 600 defines what availability means, when the expiry date applies, and how the last shipment date relates to the expiry. When a credit is amended, the expiry date may change — and the amendment mechanics interact with Article 6 in ways that produce specific, predictable failure modes.

This guide maps the availability framework, explains how amendments alter expiry and shipment dates, and isolates the failure modes that arise when amendment-driven date changes are not properly tracked.

Failure Mode Analysis

Failure Mode 1: Amendment Extends Expiry Without Beneficiary Consent

The issuing bank amends the credit to extend the expiry date. The beneficiary does not consent. Under Article 10, the original expiry date governs. If the beneficiary presents after the original expiry but before the amended expiry, the presentation is late.

Failure Mode 2: Amendment Changes Shipment Date Without Adjusting Expiry

The credit is amended to change the latest shipment date. The expiry date remains unchanged. If the new shipment date exceeds the expiry date, the credit contains an internal inconsistency. Article 6 requires the shipment date to be on or before the expiry date.

Failure Mode 3: Beneficiary Tracks Original Dates After Amendment

The credit is amended to extend both the shipment date and the expiry date. The beneficiary tracks the original dates and presents within the original window. The amended dates are more generous, but the beneficiary misses the opportunity.

Failure Mode 4: Partial Amendment Creates Date Confusion

The credit is partially amended — only the expiry date changes, not the shipment date. The bank must examine against the amended expiry and the original shipment date. Mixing the two without clear delineation produces examination errors.

Failure Mode 5: Late Presentation Under Amended Credit

The beneficiary presents after the amended expiry date. The bank refuses under Article 14(c). The beneficiary argues the original expiry was extended. The bank's refusal is correct — the amended expiry governs if the beneficiary consented.

Failure Mode 6: SWIFT MT707 Amendment Field Confusion

The issuing bank sends an MT707 amendment. The beneficiary's bank does not properly parse field 31E (new expiry date) or field 44C (latest shipment date). The beneficiary presents against incorrect dates.

Deterministic Resolution Architecture

1. Identify the operative credit version. Determine whether the credit has been amended. If amended, identify the latest amendment and confirm beneficiary consent.

2. Extract the expiry date. From the operative credit version, extract the expiry date. If the credit has been amended, use the amended expiry date (if consented) or the original expiry date (if not).

3. Extract the latest shipment date. From the operative credit version, extract the latest shipment date. Verify it is on or before the expiry date (Article 6(c)).

4. Map the availability type. From field 41A or 41D (MT700), determine whether the credit is available by sight payment, deferred payment, acceptance, or negotiation. This determines how the beneficiary accesses proceeds.

5. Verify date consistency. Confirm the latest shipment date is on or before the expiry date. If an amendment changed one without the other, verify the consistency.

6. Track amendment-driven date changes. For each amendment, record: (a) the original dates, (b) the amended dates, (c) the beneficiary's consent status, and (d) which dates govern the examination.

7. Examine document dates against operative dates. Under ISBP 745, compare document dates (bill of lading date, invoice date, certificate date) against the operative expiry and shipment dates.

8. Apply Article 14(c) for late presentation. If the presentation date exceeds the operative expiry date, the presentation is non-complying. The bank is discharged. No exceptions.

Conclusion

Article 6 creates the temporal framework for documentary credit operations. The expiry date is the hard deadline. The latest shipment date must precede it. Amendments can change these dates, but only with beneficiary consent. The systemic risk is in the transition between credit versions — tracking which dates govern at every point is the deterministic method for avoiding date-related discrepancies.

FAQ

Can a credit be amended to extend the expiry date?
Yes, under Article 10. The amendment requires the consent of the issuing bank, confirming bank (if any), and the beneficiary. The beneficiary's presentation of documents conforming to the credit and amendment is deemed consent.

What happens if the latest shipment date exceeds the expiry date?
Under Article 6(c), the latest shipment date must be on or before the expiry date. If an amendment creates an inconsistency, the credit contains an error. The bank should request clarification from the issuing bank.

Does a beneficiary have to consent to an expiry extension?
Yes. Article 10 requires beneficiary consent. If the beneficiary does not consent, the original expiry date governs. Presentation after the original expiry is late under Article 14(c).

How does Article 6 interact with ISBP 745 date examination?
ISBP 745 provides standards for examining dates on documents. The examination compares document dates against the credit's operative expiry and shipment dates. The dates are defined by Article 6.

What if the credit does not state an expiry date?
Under Article 6(d), the credit expires 21 calendar days after the date of shipment, or on the expiry date stated in the credit, whichever is earlier. But a credit should always state an expiry date — this is a drafting best practice.
