Trade Support Network

The Trade Support Network (TSN) provides a forum for the trade community to provide recommendations and input on customs automation and modernization. There are approximately 450 members of the TSN that represent the entire breadth of the trade community. The TSN is led by the Trade Leadership Council (TLC) Executive Committee (EC). The TSN includes over 65 software developers that comprise the TSN Technical Advisory Group (TAG). Their responsibilities include technical and operational input on the design and development of the Automated Commercial Environment (ACE). TSN members support the trade community in adapting new CBP processes and system updates, participating in testing of new functionality in the CERT and assisting CBP in disseminating information about program changes, system enhancements, and technical updates to the trade community. 


As needs arise, CBP works with the TSN to convene working groups to support specific modernization enhancements and ACE topics. These working groups focus on requirements, technical implementation, and policy. Current information on working groups is available below:
