CSMS # 54588041 - Interconnection Security Agreement (ISA) Renewals for Trade Participants

The Interconnection Security Agreement (ISA) documents and formalizes the security interface between Customs and Border Protection (CBP) and external automated systems.   

In accordance with implementation of the Customs and Border Protection (CBP). Information Systems Security Policy, all trade participants who transmit electronic data directly to CBP's Automated Systems are required to have a signed Interconnection Security Agreement (ISA) on file with CBP.    

ISAs are valid for three (3) years.  Trade participants should plan to submit a renewal six (6) months prior to the expiration date, or when changes occur to the company’s legal name or data origination/physical address, in order to ensure continuity of data connectivity, and to prevent service delays when requesting updates to the data connection. 

• MQIPT, Lan to Lan, sFTP, DIS/web services users, complete the eISA:  https://eisavpn.cbp.gov/  
• MPLS/MQ users, complete the MPLS ISA https://www.cbp.gov/document/guidance/interconnection-security-agreement-mplsmq-users-0   

Email the digitally-signed PDF to CBPISA@cbp.dhs.gov.

An ISA is not required from a trade participant who files electronic data to CBP's Automated Systems through a Service Center or Value Added Network (VAN), which subsequently transmits the data to CBP on behalf of the trade participant (the obligation to provide an ISA rests with the Service Center or VAN).  

For general questions about the ISA, please contact CBPISA@cbp.dhs.gov.
