U.S. Customs and Border Protection (CBP) maintains a notional development and deployment schedule (Dev/Dep schedule) of planned ACE enhancements. This schedule reflects those enhancements that have been prioritized and funded, and that CBP has begun developing. This is a notional schedule, and it is subject to modifications.
In addition to those enhancements found on the Dev/Dep schedule, CBP continues to work through emerging requirements. These emerging requirements will be added to the Dev/Dep schedule as new ACE enhancements when funding is secured and work is underway.
