X12 463 — Rail Rate Reply

The 463 transmits the reply to a rate request (466): the applicable tariff for a defined movement, conditions, fuel surcharge, validity.

Purpose

The 463 documents the rail rate quote in reply to a 466. It carries the tariff number, conditions (commodity, equipment, route), rate per car or per ton, FSC, validity period, accessorial charges.

It is generated by the railroad pricing system and lets the shipper compare offers before booking. Acknowledged by 997. The actual booking then happens via a 404 (Rail Carrier Shipment Information).

Envelope structure

The 463 travels within the three X12 envelope levels (ISA/IEA, GS/GE with functional group GZ, and ST/SE). Didactic example in release 004010:

Common segments

  • Header — ST, BGN.
  • Railroad — N1*RR.
  • Original request — REF*ZZ (466 reference), REF*ZZ (published tariff).
  • Validity — DTM*RT (start / end).
  • Rate detail — LX loop: NTE (STCC commodity), AMT*ZZ (base rate), AMT*FS (FSC).
  • Summary — SE.

Common pitfalls

  • STCC precision: a quote for 01-137-10 (wheat) does not cover 01-137-30 (durum wheat) — these Standard Transportation Commodity Codes are strictly distinct.
  • Validity overlap: if multiple 463s overlap a same period for a same corridor, the last issued wins — always check submission date.
  • Accessorial omission: demurrage, switching, scale, and FSC must be listed; omitting an accessorial generates surprise billing via 410.

Documentation

The code 463 and the name Rail Rate Reply are public and listed on x12.org/products/transaction-sets. The complete structure of loops, qualifiers and code lists is distributed by DISA via the proprietary Implementation Guides (TR3). ediverse.io covers only public concepts, the envelope and didactic examples.
