This study examines the logistics policy and system to activate the air freight known shipper system in Korea in order to suggest how to use the system necessary to convert and expand common shippers into known shippers. Even though "The Act on Aviation Safety and Security" and "Air Freight Security Criteria for Known Shippers" were revised in 2012 and 2011 each, the purpose was to regulate procedures to control aviation safety and security and air also freight security, so it does not include any measures to activate the known shipper system. Therefore, to activate the known shipper system, this study suggests measures to use the logistics security support system of "The Fundamental Law on Logistics Policy" revised in 2012, the logistics cooperation system, and consulting support as well.
