KC
Air freightKnown Consignor
A shipper approved by the aviation authority to secure its own cargo at its own premises.
In practice
A Known Consignor's cargo enters the secure supply chain at the factory, so it does not need screening later, provided the chain of custody is kept unbroken through a regulated agent. Useful for high-volume shippers with sensitive or hard-to-screen goods.
Seen in the wild
Shipper is a KC, so the truck must be sealed and the seal number recorded on the handover.
