CBP held ACE test system maintenance on February 18, 2026

CBP title: ACE Certification Standard Invasive Maintenance Window on Wednesday February 18, 2026, from 5:00 pm to 8:00 pm ET

This message is from February 17, 2026. Later CSMS messages may have changed it. See the latest trade news

What did CBP announce?

CBP announced a maintenance window for the ACE Certification (test) environment on February 18, 2026, from 5:00 pm to 8:00 pm ET. This was an invasive maintenance window, meaning the test system was unavailable during that time. The notice did not affect the live ACE production system.

What is Allied's position?

This notice concerned the ACE test environment only, not the production system Allied uses to file live entries. It is now well past the maintenance window, so it has no ongoing effect. Clients did not need to take any action then and do not need to now.

General information, not legal advice.

What does the CBP message say?

Please be advised there will be an ACE Certification Standard Invasive Maintenance Window on February 18, 2026, from 5:00pm to 8:00pm ET.
