Air Cargo Security Act

Air Cargo Security Act - Directs the Secretary of Homeland Security (DHS) to establish systems to inspect cargo to ensure the security of all cargo transported in domestic or foreign all-cargo aircraft, including in intrastate air transportation. Requires such systems to meet minimum standards that ensure equipment, technology, procedures, or personnel used to screen cargo provide a level of security commensurate with the security level for the screening of passenger checked baggage.

Directs the Secretary to: (1) establish a system for the regular inspection of shipping facilities for shipments of cargo transported in air transportation, including intrastate air transportation, to ensure that appropriate security controls, systems, and protocols are observed; and (2) enter into arrangements with civil aviation authorities of foreign countries to ensure that such inspections regularly occur at shipping facilities for cargo transported by air to the United States.

Authorizes the Secretary to increase the number of air cargo inspectors to carry out such screenings and inspections.

Directs the Secretary to establish a training and evaluation program for persons who handle air cargo to ensure that such cargo is properly handled and safeguarded from security breaches.
