This transaction set enables vessel operators, shipping companies, and automotive logistics providers to communicate vehicle application advice to receivers such as ports, distributors, and fleet management entities. Typically sent in response to vehicle shipping inquiries or application requests, the 126 provides structured notification regarding vehicle handling, routing, and logistical details. The BVA (Beginning Vehicle Advice) segment initiates each advice record and establishes the context for the shipment; the V1 (Vessel Identification) segment optionally identifies the specific vessel involved in transport; and the VAD (Vehicle Advice Detail) segment conveys detailed information about individual vehicles being advised, with optional L7 (Tariff Reference) segments providing rate or service classification data as needed.

Consider a practical scenario where AutoShip Logistics receives a request from Port Authority Miami to advise on an incoming vehicle shipment. AutoShip generates a 126 transaction set identifying the containership in the V1 segment, then populates multiple VAD segments—one for each vehicle in the shipment—documenting VIN, destination port, handling requirements, and applicable tariff codes in the L7 segments. Port Authority Miami receives this advice, confirms receipt in their systems, and uses the vehicle-level details to prepare dock space, schedule equipment, and coordinate delivery with the end customer. The structured format allows Port Authority Miami’s automated systems to parse and integrate the vehicle data directly into their warehouse management system without manual data entry.
