It has come to the attention of CBP that, since ACE implementation began, messaging responses for ISF stand alone messages in X.12 format have been inconsistent. In order to clarify this messaging, CBP is providing IG documentation for 355 and 350 messages for ISF transactions. This IG documentation is attached to this message and will be posted to the CBP website.
Please note that there is a format change from ACS. ACS response messages were in X.12 4010 format and these response messages in ACE will be in X.12 5040 format. This only applies to stand alone ISF messages in ACE. Currently, 350 response messages for ISF stand alone transmissions are being returned in 5040 format and 355 messages are being returned in 4010 format. On September 5, 2012 CBP will be transitioning the 355 messages from 4010 to 5040 format. For those already processing ISF responses from ACE, the only change in the message itself is the change from 4010 to 5040. The entire body of the message will remain the same.
