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.

The process for transmitting documentation for a Master Air Waybill begins with the incoming air carrier. They will send the eManifest to CBP, and once ACE receives the notification, they will send a Freight Status Notification (FSN) to the deconsolidator. Participants who lack the ability to transmit eManifest data to CBP can use GeTS as an alternative method to transmit AMS data.
