CBP Plans to Launch New Message Broadcast System
U.S. Customs House Guide states:
Currently, the only automated commercial system with an administrative messaging capability is the Automated Broker Interface. CBP has no broadcast mechanism for other commercial systems, such as ocean/rail manifest, air manifest and electronic truck manifest. The new CSMS listserve will allow CBP to broadcast messages not only to ABI users, but to users of all CBP automated commercial systems including the Automated Commercial Environment (ACE), Automated Commercial System (ACS) and more.
To
receive messages via CSMS, a user must subscribe
and create a subscriber profile with an email
address, password (optional), and an indication of
subjects of interest. A link to the subscription
page will be available at a later date.
