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.
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.
AI-assisted summary of a published CBP, USITC or Federal Register notice, with JFS CHB's position on it. For awareness only — always verify against the official notice before acting. 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.
