ISBP 745 A13: Later Date of Signing Compiles as the Date of Issuance

📅 2026-09-14 9 min read UCP 600 / ISBP 745

Introduction

The illusion is that a document carries two operative dates, that a printed “date of issuance” survives a later wet-ink or stamp signature, and that the two lines are a data conflict. Examiners refuse because 10 May and 18 May “do not match.” Examiners honour a document presented on 15 May because they compiled the earlier printed issuance date and never read the later signing date. Examiners mutate an on-board notation of 4 May into a 18 May shipment because they compiled A13 onto the wrong operand. Each result is a binary failure mode. ISBP 745 A13 states that a document indicating a date of issuance and a later date of signing is deemed to have been issued on the date of signing. Two dates are not two issuance dates. A13 truncates the earlier printed issuance date. Mutating A13 into a conflict test, or into a rewrite of an on-board shipment date, violates the architecture. The error is systemic.

Failure Mode Analysis

Failure Mode 1: Dual-Date Conflict Refusal

The document shows “Date of issuance: 10 May” and is signed and dated 18 May. The examiner refuses under Article 14(d) because the dates are not identical, or lists “two dates of issuance.”

A13’s two operands are present. The signing date is later. The document is deemed issued on 18 May. Article 14(d) requires the data, read with international standard banking practice, not to conflict. A13 is that practice. Identity is not required. The refusal mutates two stacked dates into a conflict. A13 is violated.

Deterministic resolution: Confirm both operands. If a date of issuance and a later date of signing appear, compile one deemed issuance date: the date of signing. Do not emit an Article 14(d) discrepancy for those two dates. Then run Article 14(i), and any article that consumes the issuance date, against 18 May.

Failure Mode 2: Earlier Printed Issuance Survives; Article 14(i) Truncated

The document shows issuance 10 May and is signed 18 May. Presentation is 15 May. The examiner honours because 10 May is not later than presentation, or because A11 is satisfied by the printed issuance date.

A13 has already deemed issuance on 18 May. Article 14(i) forbids a document dated later than its date of presentation. 18 May is later than 15 May. Honour truncates A13 and Article 14(i). The same truncation appears when an insurance document’s later signing date is after the date of shipment and no earlier effectiveness is shown, yet the examiner tests Article 28(e) against the printed issuance date.

Deterministic resolution: After A13 fires, discard the earlier printed issuance date as the operative issuance date. Test Article 14(i) against the signing date. Test Article 28(e) against the signing date unless effectiveness from a date not later than shipment appears. If an original transport document has no on-board shipment date, test Article 20(a)(ii)’s default shipment date against the deemed issuance date, then test Article 14(c) against that shipment date.

Failure Mode 3: On-Board Notation Mutated by A13

A bill of lading shows a printed issuance date of 10 May, an on board notation dated 4 May, and a signature dated 12 May. The examiner refuses because A13 deemed issuance on 12 May and therefore deemed shipment on 12 May, which is after the latest shipment date, or which restarts Article 14(c).

Article 20(a)(ii) states that the date of issuance of the bill of lading is deemed the date of shipment unless the bill of lading contains an on board notation indicating the date of shipment, in which case the date stated in the on board notation is the date of shipment. The on-board date is 4 May. A13 compiles issuance as 12 May. A13 does not compile shipment as 12 May once the on-board operand is present. Mutating A13 onto the on-board date violates Article 20(a)(ii). Do not examine the bill of lading under Article 18. Do not examine the invoice under Article 20.

Deterministic resolution: Classify the date. Issuance: A13 if both dates appear. Shipment on a bill of lading: on-board notation date if present; otherwise the deemed issuance date under Article 20(a)(ii). Latest shipment in the credit tests the shipment date, not the signing date. Article 14(c) runs from the shipment date, not from A13’s issuance date once an on-board date exists.

Deterministic Resolution Architecture

  1. Classify the instrument. A13 is a general-principles date compile. It is not Article 18, Article 20 or Article 28. Do not examine a commercial invoice, a bill of lading, or an insurance document under A13 as if A13 were those articles. After A13 compiles issuance, hand that date to the article that actually consumes it.

  2. Test A13’s two operands. A date of issuance is indicated. A later date of signing is indicated. If either operand is missing, A13 is off. If the signing date is not later, A13 is off. An unsigned commercial invoice under Article 18(a)(iv) has no signing date. A13 is off.

  3. Compile one deemed issuance date. The document is deemed to have been issued on the date of signing. Truncate the earlier printed issuance date as the operative issuance date.

  4. Decouple conflict. Do not refuse under Article 14(d) because the two dates are not identical. A13 is the practice that stacks them.

  5. Run Article 14(i) against the deemed date. The document must not be dated later than its date of presentation. The deemed date is the signing date.

  6. Decouple shipment from issuance on a bill of lading. If an on board notation indicates the date of shipment, that date is shipment under Article 20(a)(ii). A13 does not mutate it. If there is no such notation, the deemed issuance date is the date of shipment under Article 20(a)(ii). Then run Article 14(c) from that shipment date.

  7. Decouple insurance. Article 28(e) and ISBP 745 K10 test the insurance document date, after A13 if A13 fired, against the date of shipment, unless cover is effective from a date not later than shipment. Do not examine the insurance document under Article 20.

  8. Isolate A13 from A11, A12, A14, A15 and Article 3. A11 asks whether a date must appear. A12 asks whether a certificate may issue after shipment. A14, A15 and Article 3 calculate periods with “from,” “after,” “before,” “within.” None of them is the later-signing compile.

  9. Stay on the face of the documents. Article 14(a) and Article 5. Do not telephone the issuer to ask which date was “intended.” Do not import the sale-contract signing date under Article 4(a).

  10. Honour or refuse on the gate that fired. If A13 compiled a signing date that still satisfies Article 14(i) and every consuming article, and the presentation otherwise complies, Article 15(a) requires honour. If the deemed date is later than presentation, refuse under Article 16(a) and give the Article 16(c) single notice naming A13’s deemed issuance date and Article 14(i). Do not list dual-date conflict. Do not list an on-board date as rewritten by A13.

Conclusion

ISBP 745 A13 is the later-signing architecture for the date of issuance. A document indicating a date of issuance and a later date of signing is deemed to have been issued on the date of signing. Article 14(d) does not treat those two dates as a conflict. Article 14(i) tests the deemed date against the date of presentation. Article 20(a)(ii) uses the deemed issuance date as the date of shipment only when no on board notation indicates the date of shipment. Article 28(e) tests the insurance document date, after A13 if A13 fired. Article 18(a)(iv) leaves an unsigned invoice outside A13. A14, A15 and Article 3 are period rules. They are not A13. Examiners who refuse for dual dates violate A13. Examiners who honour on the earlier printed issuance date truncate Article 14(i). Examiners who rewrite an on-board shipment date with A13 violate Article 20(a)(ii). The result is deterministic.

FAQ

Q1: A certificate shows “Date of issuance: 10 May” and is signed and dated 18 May. Presentation is 16 May. Does the presentation comply as to Article 14(i)?

No. ISBP 745 A13 states that a document indicating a date of issuance and a later date of signing is deemed to have been issued on the date of signing. The deemed date is 18 May. UCP 600 Article 14(i) states that a document must not be dated later than its date of presentation. 18 May is later than 16 May. The earlier printed 10 May is not the operative date.

Q2: The same certificate shows 10 May and 18 May. The examiner lists “conflicting dates” under Article 14(d). Is that a discrepancy?

No. Article 14(d) states that data need not be identical to, but must not conflict with, other data when read with international standard banking practice. A13 is that practice: the later signing date compiles as the issuance date. The two dates stack. They do not conflict.

Q3: A bill of lading is issued 10 May, signed 12 May, and bears an on board notation dated 4 May. The latest shipment date is 5 May. Did shipment occur on 12 May?

No. A13 deems the bill of lading issued on 12 May. UCP 600 Article 20(a)(ii) states that the date of issuance is deemed the date of shipment unless the bill of lading contains an on board notation indicating the date of shipment, in which case that notation date is the date of shipment. Shipment is 4 May. A13 does not mutate the on-board date. Do not examine the bill of lading under Article 18.

Q4: The commercial invoice is dated 10 May and is not signed. Does A13 move the invoice date?

No. Article 18(a)(iv) states that a commercial invoice need not be signed. A13 requires a date of issuance and a later date of signing. There is no date of signing. A13 is off. Do not refuse the invoice for want of a signing date. Do not examine the invoice under Article 20.

Q5: Does A13 change how “from” and “after” calculate a presentation period?

No. ISBP 745 A15 states that “from” and “after,” when used to determine a maturity date or period for presentation, exclude that date in the calculation of the period. UCP 600 Article 3 states the same exclusion for maturity, and a different inclusion rule for a period of shipment. A13 compiles the date of issuance when a later signing date appears. A13 does not calculate a period. Isolate A13 from A15 and Article 3.

Did You Know?

UCP 600 Article 14(i) states that a document must not be dated later than its date of presentation.
