This X12 transaction set is a cartage carrier’s formal response to a work assignment request. The carrier sends the 225 to the requesting party—typically a freight forwarder, non-vessel-operating common carrier (NVOCC), or freight broker—to confirm receipt and acceptance of cartage work details. The response message structure begins with the ST (Transaction Set Header) segment for envelope control, followed by the SCP (Beginning Segment for a Cartage Work Assignment Response) segment, which contains the core response data and references the original assignment. Optional L11 (Business Instructions and Reference Number) segments allow the carrier to attach handling notes or additional references up to five times, and the SE (Transaction Set Trailer) segment closes the transaction set for audit and control purposes.

ABC Cartage Services receives a cartage work assignment from XYZ Freight Forwarders requesting pickup of a container from the Port of Los Angeles and delivery to an inland warehouse. ABC Cartage responds by sending a 225 transaction set in which the SCP segment confirms acceptance of the assignment and references the original request identifier. ABC includes two L11 segments: one noting the assigned driver and truck number, and another providing dispatch contact information for XYZ’s warehouse. Upon receipt, XYZ’s system records that the cartage work has been accepted and can notify the shipper of the confirmed pickup time and carrier details.
