This transaction set communicates terminal operations and intermodal ramp activity information between transportation partners. Typically sent by terminal operators, freight forwarders, or intermodal service providers to shipping lines, motor carriers, or logistics coordinators, it reports the status and movement of equipment and cargo at port and intermodal facilities. The Q5 (Status Details) segment conveys the operational status being reported, while the N7 (Equipment Details) segment identifies the specific containers or trailers involved, and the R4 (Port or Terminal) segment specifies the facility location where the activity occurred.

Consider a scenario where Port Authority Terminal Services sends a 322 transaction to Maersk Line reporting the arrival and positioning of containers. The message includes equipment details such as container numbers and seal information through the N7 segment, specifies the terminal location in Jacksonville via the R4 segment, and documents date/time information through DTM segments to indicate when the equipment was received and positioned. If the shipment contains hazardous materials, the H1 segment within the L0 loop records those material classifications. Port Authority Terminal Services uses this transaction to confirm that Maersk’s containers have been successfully received at the facility and are ready for pickup or further processing.
