- King Pin:
- A large steel pin located beneath the front of a trailer. The king pin fits down into the jaws on the fifth wheel of a tractor or a dolly, thereby hooking the tractor up to the trailer, or the pup up to the first trailer.
- Kitting:
- See Assembly.
- Known Shipper:
- A shipping security status that allows a shipper to move freight on any commercial airline. A known shipper has a valid account number with an IAC (Indirect Air Carrier) and has executed the proper documents required by the TSA to become a known shipper to the IAC. (Estes Express Lines is an IAC.) Unknown shippers are not permitted to ship anything via passenger airplane.
