What did CBP announce?

CBP announced a maintenance window for the ACE certification (test) environment on July 1, 2026, from 5:00 p.m. to 8:00 p.m. ET. The message did not describe any impact on the production ACE system used for filing entries. This was a routine, time limited maintenance notice.

What is Allied's position?

This notice concerned a test environment, not the production system we use to file entries. It had no effect on entries we filed for clients and required no action from importers or shippers. Clients do not need to do anything about this notice now.

General information, not legal advice.

What does the CBP message say?
