Air Cargo Security Improvement Act of 2018

Air Cargo Security Improvement Act of 2017 This bill directs the Transportation Security Administration (TSA) to: (1) establish an air cargo security office, (2) conduct a pilot program to test the use of screening equipment using computed tomography technology, (3) report to Congress on actions to improve the Certified Cargo Screening Program, (4) develop standards for the use of third-party explosives detection canines for the primary screening of air cargo, and  (5) request a review and assessment of the known shipper program. The Government Accountability Office must review the TSA's screening processes and procedures for examining air cargo entering the United States and assess its risk-based strategy for examining such cargo. The bill amends the Homeland Security Act of 2002 to provide statutory authority for the air cargo advance screening program.
