Letter of Intent (LOI) Form - Commodity Data (EEI)

A Letter of Intent is required to participate in the Automated Export System (AES). The Letter of Intent (LOI) is a written statement of a company's desire to participate in the AES, and implies the development or purchase of a software solution by your company, which conforms to the AES data formats.

Upon receipt of your LOI, a Customs Client Representative and a Census Client Representative will be assigned to serve as your technical advisors during development, testing and implementation of the AES.

Interconnection Security Agreement

In accordance with implementation of the Customs and Border Protection (CBP) Information Systems Security Policy, all participants that transmit electronic data directly to the AES or the Automated Commercial System (ACS) are required to have a signed Interconnection Security Agreement (ISA) on file with CBP.

For information to identify those participants that are required to file an ISA and instructions on how to complete and forward the ISA to CBP, see the CBP ISA in the related links:
