AMS Air is open to airlines, warehouses (CFS), deconsolidators, CBP ABI entry filers (customs brokers), and service centers. Any deconsolidator or entry filer with type 1, 2, or 3 Customs bond type can send AMS eManifests to CBP.

It is up to the incoming air carrier to transmit the documentation for the Master Air Waybill. Once the carrier sends the eManifest to CBP, the ACE system will send the Freight Status Notification (FSN) to the deconsolidator. Participants without the technical capacity to transmit eManifest data to CBP can make use of Service Centers such as Customs City Global Solutions to transmit their AMS data.
