X12 920 — Loss or Damage Claim - General Commodities
The 920 carries a loss or damage claim (general commodities) against a carrier: shipment reference, nature and extent of the damage, claim amount.
Purpose
The 920 documents the post-delivery claim addressed by the shipper, consignee or party-in-interest to the carrier: Pro number / B/L reference, affected line(s), damage description (total loss, partial loss, damage), claimed amount, calculation basis (invoice value, replacement value, declared value), supporting documents.
It is part of the transport-claim cycle governed by the NMFTA and transport contracts (Carmack Amendment in US interstate). Acknowledged by 997, it is typically followed by a 926 (Claim Status Report and Tracer Reply) from the carrier.
Envelope structure
The 920 travels within the three X12 envelope levels (ISA/IEA,
GS/GE with functional group LO, and ST/SE).

Common pitfalls
- Claim deadline: Carmack Amendment requires 9 months post-delivery for US interstate; a 920 past deadline is legally weak — encode timestamps and trace.
- Value basis: invoice vs declared vs replacement value — encode explicitly via
AMTqualifier; absent that, the carrier defaults to the least claimant-friendly basis. - Missing evidence:
PWKmust point to photos + B/L + invoice + inspection report; an unsupported claim is typically rejected within 30 days without audit.
