Critical entry time (CET). CET is the latest time that a minimal amount of mail can be tendered to designated induction points in the postal network in order for it to be processed and dispatched to meet service standards. For origin entry Standard Mail, CETs are locally determined.

An appointment unique to DNDC drop shipments of bedload Parcel Select mail, wherein the Postal Service waives the driver unload responsibility and allows a shipper to leave the vehicle for Postal Service unloading (up to 12 hours from the time of appointment or arrival, whichever is later).
