When the documentary credit message exceeds the maximum input message length, additional documentary credit information should be transmitted via one or more MTs 721. Up to seven MTs 721 may be sent in addition to the MT 720.
Information conveyed in a designated field in the MT 720 must not be repeated in any related MT 721. Information in any related MT 721 must not conflict with any information that is present in this 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.
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.
