The Automated Commercial Environment (ACE) is the U.S. trade processing system of US Customs and Border Protection (CBP) to automate border processing and to enhance border security. The advance submission of manifest data by truck carriers or their designated agents ensures proper risk assessment of cargo takes place before goods enter the U.S.

ACI Highway eManifest is an extension of the ACI ocean and air initiatives that will require the electronic transmission of advance cargo and conveyance information to CBSA from carriers for all highway shipments before entering Canada.

CBSA ACI Highway eManifest is the Canadian equivalent of the U.S. CBP Automated Commercial Environment (ACE) eManifest program. Transmission of highway cargo and conveyance data must be received and processed by the CBSA a minimum of one hour before arrival at First Point of Entry.
