CBP held ACE certification maintenance window on July 29, 2026
CBP title: ACE Certification Standard Invasive Maintenance Window from 5:00 p.m. ET to 8:00 p.m. ET
What did CBP announce?
CBP announced a standard invasive maintenance window for the ACE Certification environment on July 29, 2026, from 5:00 p.m. to 8:00 p.m. ET. The message did not describe any effect on production ACE filings. This is now a past, routine maintenance event.
What is Allied's position?
This notice concerned a certification test environment, not production filing, so it did not affect entries we filed for clients. No client action was needed at the time, and none is needed now.
General information, not legal advice.
What does the CBP message say?
There will be an ACE certification standard invasive maintenance window on July 29, 2026, from 5:00 p.m. ET to 8:00 p.m. ET.
