X12 354 — U.S. Customs Automated Manifest Archive Status
The 354 transmits the archive status of a US Customs automated manifest (AMS) — accepted, pending, rejected, purged — to the carrier or its agent.
Purpose
The 354 documents the technical status of an AMS manifest filing: received, accepted by ACE, pending data, rejected (with error code), purged after retention period. It is the proof of 24-Hour Rule compliance.
It is consumed by ocean / air carrier compliance officers. Acknowledged by 997. Serves as audit trail for CBP investigations.
Envelope structure
The 354 travels within the three X12 envelope levels (ISA/IEA,
GS/GE with functional group AS, and ST/SE).

Common pitfalls
- Rejected ≠ purged: a rejected AMS is fixable; a purged AMS after retention expiration requires a complete refile. Confusing both wastes time.
- Error code catalogs: CBP publishes an error code dictionary — a 354 without the source code makes support triage impossible.
- Retention period: CBP typically keeps manifests 5 years; a 354 with PURGED status is not an error, it is a normal lifecycle event.
