ACE Production Maintenance Window: August 15–16, 2026 (10:00 p.m.–4:00 a.m. ET)
CBP has scheduled a standard invasive maintenance window for the ACE Production environment from 10:00 p.m. ET Saturday, August 15, 2026 through 4:00 a.m. ET Sunday, August 16, 2026. During this window, ACE Production may be unavailable, potentially affecting entry filings and cargo release transactions.
Broker's Take
We will stage any time-sensitive entries ahead of Saturday evening to avoid the maintenance blackout — importers with perishable or time-critical cargo arriving that weekend should notify us early in the week.
