ACE Production Maintenance Window: September 26–27, 2026
ACE Production will be offline for standard invasive maintenance from 10:00 p.m. ET Saturday, September 26, 2026 through 4:00 a.m. ET Sunday, September 27, 2026, during which entry filings and manifest transmissions will be unavailable. Importers and brokers with time-sensitive filings scheduled around that window need to account for the six-hour outage.
We treat every ACE production maintenance window as a filing pipeline management issue — our position is that entries with quota sensitivity or perishable cargo should be advanced or deferred clear of the outage window as a matter of standard practice.

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.
