International ACH Transaction (IAT) items can be returned for specific reasons outlined in the ACH Rules. IAT entries use the same return timeframes as other ACH Entries under the Nacha Operating Rules. Note that these items cannot be returned or rejected solely because your institution does not want to process IAT entries. However, you may follow proper procedures to return an IAT if your member claims it is unauthorized and the entry is not a positive SDN hit. There are no return reason codes that are blocked from use with IAT, but the Dishonored Return and Contested Dishonored return codes are not allowed for use with IAT entries.
It is critical that all information requested in this form is provided to ensure that your IAT return can be performed in a timely and accurate manner. The OpsEngine Data Center team will e-mail you when the return is completed. Please direct any questions regarding ACH and returns to the Client Services Team.
