In accordance with implementation of the Customs and Border Protection (CBP) Information Systems Security Policy, all participants that transmit electronic data directly to CBP's Automated Export System (AES) or Automated Commercial System (ACS) are required to have a signed Interconnection Security Agreement (ISA) on file with CBP. The following provides information to identify those participants that are required to file an ISA and instructions on how to complete and forward the ISA to CB

AES and ACS participants who connect directly to these CBP systems are required to:

1. Edit/Complete one of the following ISA documents (in the Related Links column on the right side of this page) per the instructions provided below.

   1. ISAFRAME.EXE is for Frame/MQ users.
   2. ISAMPLS.EXE is for MPLS/MQ users.
   3. eISATVPN.EXE is for VPN users.

   Note: The files are self-extracting zip files, each containing an ISA document in MS Word format. Click on the appropriate file (in the Related Links column on the right side of this page) and follow the provided instructions to download the ISA document to your local hard drive.

2. For Frame/MQ and MPLS/MQ Users, print the completed document and have it signed by a corporate officer of your company.

An ISA is not required from any participant who submits electronic data to CBP's, AES or ACS systems solely by any one of, or any combination of, the following methods:

1. Filing through the Census Internet application AESDirect
   (The obligation to provide an ISA rests with the AESDirect contract company.)

   If the above exclusion does not apply, then you connect directly to CBP and you must complete and return an ISA document. Failure to provide an ISA will prevent CBP from establishing the communications profile that permits transmission to AES or ACS or will prompt removal of a preexisting profile.
