X12 326 — Consignment Summary List

The 326 transmits the summary list of consignments — multiple shipments associated to a single transport — to facilitate grouped tracking and invoicing.

Purpose

The 326 documents the grouping of consignments in a single transport: for each consignment, BL number, shipper, consignee, weight, value, status. It is used by LTL carriers and freight forwarders to provide an overview of a multi-consignment trip.

It feeds TMS, billing systems, and carrier revenue management. Acknowledged by 997.

Envelope structure

The 326 travels within the three X12 envelope levels (ISA/IEA, GS/GE with functional group CL, and ST/SE). Didactic example in release 004010:

Common segments

  • Header — ST, B3 (Beginning Segment for Carrier's Invoice).
  • Trailer — N7.
  • Consignment loop — LX: N9*BM (BL), N1*SH (Shipper), N1*CN (Consignee), MEA*WT*GW (Gross Weight).
  • Summary — SE.

Common pitfalls

  • Consignment vs shipment: terms are sometimes interchangeable, but in LTL a consignment can contain several handling units; clarify with MAN segments.
  • Pro-rated billing: a 326 must indicate if billing is per consignment or pro-rated by weight share — different flow toward 210.
  • Customs implications: for cross-border, each consignment may have its own customs status — a 326 ignoring these differences causes border delays.

Documentation

The code 326 and the name Consignment Summary List 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.
