Air AMS carriers can do this after in-bond transfer authorization or after local transfer authorization to an Air AMS deconsolidator. Air AMS freight forwarders, nominated as an agent for specific air waybills and not in possession of cargo at a Customs bonded facility, can also do this. Air AMS uses IATA Cargo IMP message structuring techniques. Each transmission to or from Customs must contain the standard IATA communications address format encompassing each record transmitted. The address format is used to direct the transmission to the proper addresses, assign a priority, and to delineate the detail records to follow.
All applications require the use of the standard communications address.
Rail AMS allows rail carriers to electronically transmit bill information to Customs. This allows Customs an opportunity to review the submitted documentation and determine, in advance, whether the merchandise merits examination or release. The carrier, upon receiving a release from Customs, is able to make decisions on staging cargo, and the importer can arrange for examination, release, and further distribution of the merchandise. Approved rail carriers can electronically arrive their own conveyances at the first U.S. port and do timely updates to manifest records with the actual arrival date. Secondary Notify Party Rail carriers can designate up to two additional AMS participants per bill of lading to receive status notifications.
