When the documentary credit message exceeds the maximum input message length, additional documentary credit information should be transmitted via one or more MT 721s. Up to three MT 721s may be sent in addition to the MT 720.
Unless otherwise specified, a documentary credit advised to the beneficiary or another advising bank based on a SWIFT message constitutes an operative credit instrument.
For freely negotiable documentary credits, the Receiver must add sentences to the effect that:
The advice to the beneficiary must be presented at each negotiation.
The negotiating bank must note each negotiation on that advice.
To avoid misunderstandings, where possible, banks are to use Identifier Codes rather than expressions such as ourselves ,yourselves ,us, or you.
If this message is used to transfer a non-bank issued documentary credit, field 50B must be present.
The transferring bank must transfer the documentary credit, including all its details, in a way that is clear and unambiguous to the beneficiary.
