Routing and Carrier Instruction

This document instructs carriers and logistics partners on routing, handling, and transportation requirements for shipments. Shippers or freight forwarders send the 853 to carriers, third-party logistics providers, or freight brokers to communicate detailed instructions before or during transportation. The transaction typically originates after orders are placed or shipments are prepared. The BGN (Beginning Segment) establishes the transaction purpose and date, the N1 Loop identifies parties involved (shipper, carrier, consignee, and other participants), and the TD5 Loop (Carrier Details) provides routing sequences, transit times, equipment specifications, and special handling requirements for individual legs or modes of transportation.

For example, MediSupply Inc., a medical equipment distributor, sends an 853 to Logistics Premier to instruct them on how to route a shipment of temperature-sensitive diagnostic devices to Regional Hospital. The document specifies in the N1 Loop that MediSupply is the shipper, Regional Hospital is the destination, and includes contact information for both. Within the TD5 Loop, MediSupply specifies that the shipment must travel via refrigerated truck, includes hazmat handling notes in the TD4 segment, references the order number, and provides time windows for pickup and delivery. The carrier uses these detailed instructions to execute the transportation exactly as planned, ensuring compliance with product requirements and delivery commitments.
