ACE Air eManifest

ACE (Automated Commercial Environment) is the name of the CBP (Customs & Border Protection) platform to process eManifest submissions from carriers, freight forwarders, importers, warehouses and customs brokers.  The system was previously known at AMS (Automated Manifest System)

The ACE Air eManifest system is available to the following entities:

  • Air carriers

  • Customs brokers/Importers

  • Warehouses/ CFS (Container Freight Stations)/ECCF (Express Consignment Carrier Facility)

Air carriers must submit AWB (Air waybill data) at the master level.  If the freight forwarder or warehouse does not elect to send the HAWB (House airwaybill data) then the HAWB information must be given to the airline so the information can be submitted by the airline.

Timelines for Submission

The ACE Air information must be submitted to CBP at least 4 hours before the arrival of the aircraft.

CBP LOI (Letter of Intent)

Each participant in the ACE Air eManifest program must complete an LOI (letter of intent).  Customs City Global Solutions has summarized the LOI requirements on this form.

Each participant must have the proper CBP identifiers and bonds.  A summary of the identifiers and bonds required for the ACE Air eManifest program are as follows:

Air Carrier

  • IATA/ICAO carrier code

  • IATA AWB prefix

  • International carrier bond (type 3)

Customs Broker

  • Filer code

  • Importer bond (type 1)

Warehouse / CFS (Container Freight Station)

  • FIRMS code

  • Custodian bond (type 2)

  • International carrier bond (type 3)

AWB Types

The following AWB types exist in the ACE Air eManifest system

  • MAWB– Master airwaybill. This type of AWB means the airline will be expecting the freight forwarder to submit HAWB’s against the MAWB number

  • Simple- This is a type of MAWB submitted by the airline. The Simple AWB means that no freight forwarder will be submitting any HAWB’s against the AWB.

  • HAWB- The HAWB is submitted by the importer / customs broker / CFS or ECCF operator

Permit to Proceed

This is a special movement of the aircraft to another airport.  The approval to move the aircraft is given by CBP by the issue of a permit.  The airport destination and ETA are updated on the manifest in this circumstance.

Split Shipments

This type of shipment is necessary from time to time due to weight restrictions on the aircraft.  In these circumstances the AWB is updated to include a split shipment indicator.  The boarded piece count and weight are updated on the AWB.

In-Bond Shipments & Local/International Transfers

In-bond and transfer shipments will be indicated as being Domestic, International or FROB (Freight Remaining Onboard). When the in-bond shipment is moving to another airline the AWB # can be used as the in-bond number. When transferring the freight to another carrier such as a highway carrier the EIN # of the highway carrier must be included. Freight can also be transferred to a warehouse. A 9 digit in-bond number also has to be included in the transmission.

Freight Status Query (FSQ)

The FSQ is sent automatically from our system after the submission of the AWB. This is necessary to obtain the status of the AWB in the CBP system. FSQ messages can be sent at any time and the following statuses may be requested from CBP about any AWB.

  • 01 – Request for routing information

  • 02 – Request for current record status

  • 03 – Request for a nominated agent

  • 04 – Request for retransmission of FSN messages

  • 05 – Request for routing information, current record status, nominated agent, current AWB information on file returned in FSC/10 message

  • 06 – Request for HAWB information for supplied MAWB.

Freight Status Notification (FSN)

There are two types of FSN in the ACE Air eManifest system.

You can send an FSN to CBP to notify of the following circumstances.

  • The in-bond cargo arrived at the destination

  • Local transfer of consolidated cargo

  • In-bond cargo exported from the US

You can also receive FSN updates from CBP. Some of the most common FSN’s received from CBP are as follows:

  • 1A- Entry processed: CBP intensive examination required.

  • 1B- CBP intensive examination complete.

  • 1C- Entry processed: CBP general examination.

  • 1D- In-bond movement authorized by CBP.

  • 1E- In-bond transfer not authorized, held at the port of arrival per CBP.

  • 1F- CBP local transfer authorized.

  • 1G- CBP local transfer not authorized.

  • 1J-CBP permit to proceed movement not authorized.

  • 1H- CBP hold at the port of arrival

Direct Injection Shipments

With the explosion of e-commerce, shipments have led to the creation of the supply-chain logistics term of Direct Injection. Direct Injection means the grouping of shipments of smaller size and weight at the origin and sent on a direct flight to the destination country. This model is dependent on volume so large volume e-commerce countries like the US are where it is implemented.

Once the cargo reaches the destination country the local last-mile delivery company will deliver to the customer. Often packages are labeled with domestic shipping labels at origin giving the customer the look and feel of domestic delivery.
The carrier can usually provide end-to-end tracking with delivery confirmation.

Using Sec 321 shipment type in ACE Air allows the shipper to deliver to the US customer on a DDP (Delivered Duty Paid) to the customer. To qualify for section 321 the total value of the cargo delivered to a customer cannot exceed $800 USD.

CSV Upload and Cargo Imp Messages

Customers can make use of our CSV file to upload large numbers of shipments.

Customers can also send us FWB or FHL messages which we will map into the CBP format.
