A known shipper is a term used in the air cargo industry to refer to a person, company, or organisation that has been pre-screened and approved by the relevant security authorities, and is deemed to pose a low risk to air transportation security. The concept of a known shipper is intended to help improve air cargo security by allowing security authorities to focus their resources on higher-risk shipments and persons, while enabling trusted and reliable shippers to benefit from streamlined and expedited security procedures.
