ACE Production Maintenance Window: September 19–20, 2026
CBP scheduled standard invasive maintenance on the ACE production environment from 10:00 p.m. ET Saturday, September 19, 2026 through 4:00 a.m. ET Sunday, September 20, 2026, during which ACE filing capabilities may be unavailable. Importers with time-sensitive entry filings or cargo release needs should factor this window into their operational planning.
Our position is that weekend ACE maintenance windows, while routine, require pre-staging of any entries due during the outage period; we confirm our filing queues ahead of each scheduled window.

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.
