Nacha Issues Revised IAT Scenario H to Help Clarify Use of International ACH Transactions

To help clarify use of International ACH Transactions (IAT) for transactions initiated by money transmitters or third-party service providers that involve a U.S. bank and foreign bank, Nacha has issued a revised IAT Scenario H.  The revised IAT Scenario H provides guidance on when to format entries as IATs when money transmitters or third-party service providers use the ACH Network to debit a U.S. bank account to send funds to another country or credit a U.S. bank account with funds from another country.  Ultimately, the revised IAT Scenario H concludes that these credit/debit transactions to U.S. banks should be formatted as IAT entries.  This is the case even if the money transmitter or third-party service provider is consolidating the funds from the ACH debit entries in a U.S. bank account and then moving the consolidated funds to the receiving country.

Note: Nacha has reviewed the revised IAT Scenario H with the Office of Foreign Assets Control and confirmed the accuracy of its conclusion defining the inbound ACH debit or credit to be formatted as IAT entries.
