If the collecting bank does not apply the ICC Uniform Rules for collections, this should be stated in the message.
The MT 410 may be a single or a multiple message. When it is a multiple message, it must refer to one collection (for at least one of the banks).
When one of the banks views a collection with more than one item as more than one collection, fields 20 and 21 are to be used as follows:
The remitting bank sends what it considers to be two separate collections (references '1' and '2') to the collecting bank.
The collecting bank, when sending an acknowledgement, considers this to be one item (reference 'A').
Fields 20 and 21, will appear as:
The remitting bank sends what it considers to be one collection (reference '1') to the collecting bank.
The collecting bank, when sending an acknowledgement, considers this to be two items (reference 'A' and 'B').
Fields 20 and 21 will appear as:
A collection instruction involving two or more currencies must be acknowledged by two or more separate MT 410s.
The MT 410 must not be used to acknowledge an MT 405 Clean Collection.
