ACE Production Maintenance Window Scheduled September 12–13, 2026
CBP has scheduled standard invasive maintenance on the ACE production environment from 10:00 p.m. ET Saturday, September 12, 2026, through 4:00 a.m. ET Sunday, September 13, 2026, during which ACE services may be unavailable.
We read this as a routine but operationally relevant outage window — entries and filings that fall within or near that overnight period will need to be queued ahead of the maintenance start time to avoid transmission delays.

Our position is general commentary on a published notice, not legal advice and not a binding opinion on any shipment. Nothing here creates a broker-client relationship or a duty of care, and it is not a substitute for a ruling, a licensed review of your facts, or the official notice itself.
