CBP title: UPDATE: ACE Air EDI and Entry Summary EDI Experiencing Slow Processing
This message is from January 23, 2026. Later CSMS messages may have changed it. See the latest trade news
What did CBP announce?
CBP announced a network restart between 8:00pm and 9:00pm EST that caused temporary delays in processing incoming EDI messages for ACE Air and Entry Summary. CBP asked users not to refile messages that received no response during the window, since those would process once the connection was restored. Users could also see slowness in ACE Portal applications during that time. This affected importers, brokers and carriers filing through ACE that evening.
What is Allied's position?
This was a routine, one-time maintenance window from January 2026 and has already passed. It did not change any filing requirements or deadlines. Clients do not need to take any action regarding this notice.
General information, not legal advice.

Please do not refile messages where no response is received during the period, as those messages will be processed when network connection is restored.
