ACE Truck Manifest Modernization – Information on Upcoming Deployments

Plain-English explanation

CSMS 51401505 is a U.S. Customs and Border Protection (CBP) Cargo Systems Messaging Service bulletin (system update), published on March 24, 2022. It carries the official CBP guidance brokers and importers must follow for the topic — "ACE Truck Manifest Modernization – Information on Upcoming Deployments". CSMS messages are the operational layer between Commerce determinations and at-the-border collections: when Commerce publishes a new rate, scope ruling, or instruction, CBP turns it into a CSMS that ACE/ACS systems and brokers act on.

CSMS #51401505 - ACE Truck Manifest Modernization – Information on Upcoming Deployments U.S. Customs and Border Protection sent this bulletin at 03/24/2022 01:16 PM EDT Cargo Systems Messaging Service CSMS #51401505 - ACE Truck Manifest Modernization – Information on Upcoming Deployments On January 30, 2022, U.S. Customs and Border Protection (CBP) began the multi-release deployment of Enhancements to ACE Truck Manifest – Phase 2, also known as ACE Truck Manifest Modernization (TMM). The first deployment took place at the port of Brownsville, TX, and the second deployment occurred on March 13, 2022 at the port of Buffalo, NY. Enhancements to ACE Truck Manifest – Phase 2 is focused on enhancing the CBP user interface (UI) for processing truck manifests. CBP did not initially anticipate trade user impacts as part of Phase 2, but it has been determined that previously relaxed validations in the legacy truck manifest application are now enforced in TMM and have resulted in errors for some users. TMM validations are being enforced as documented in the Truck Manifest X.12 - 309 and EDIFACT CUSCAR EDI implementation guides found at https://www.cbp.gov/trade/automated/technical/ace-import-manifest-documentation TMM will continue to operate in Brownsville and Buffalo. Due to the identified issues mentioned above that affect some trade users, CBP has delayed subsequent releases of TMM to give trade users the opportunity to make necessary adjustments to adhere to the implementation guides. The schedule below reflects the remaining deployment schedule for TMM: • Laredo, TX: Deployment delayed to April 24, 2022 • Detroit, MI: Deployment May 15, 2022 • All Remaining Ports: Deployment June 5, 2022 • Retire Legacy Truck Manifest Application (R4): June 20, 2022 • Deployment of Enhancements to Truck Manifest – Phase 3: July 11, 2022 For questions about TMM and the upcoming deployments, please contact ASKACE@cbp.dhs.gov Update your subscriptions, modify your password or e-mail address, or stop subscriptions at any time on your Subscriber Preferences Page .
