To address ongoing aviation security threats, Customs and Border Protection (CBP) amended its regulations pertaining to the submission of advance air cargo data to implement a mandatory Air Cargo Advance Screening (ACAS) Program for any inbound aircraft required to make entry under the CBP regulations that will have commercial cargo aboard. The ACAS Program requires the inbound carrier or other eligible party to electronically transmit specified advance cargo data (ACAS data) to CBP for air cargo transported onboard U.S.-bound aircraft as early as practicable, but no later than prior to loading of the cargo onto the aircraft. The ACAS Program enhances the security of the aircraft and passengers on U.S.-bound flights by enabling CBP to perform targeted risk assessments on the air cargo prior to the aircraft’s departure for the United States. These risk assessments identify and prevent the loading of high-risk air cargo that could pose a risk to the aircraft during flight.
