How will the Automated Import System (AIS) impact your business?

Temporary Storage Facility (TSF) operators

If you are an authorised TSF operator, declarations will be required for non-European Union goods entering and leaving your premises. The following declarations must be submitted electronically using the AIS:

  • Presentation Notification (PN/G3)
  • Temporary Storage Declaration (TSD/G4)
  • Arrival notification in case of movement of goods under temporary storage (G5)
  • Customs import declaration.

The G3 and G4 can be lodged as a combined declaration into the AIS.

G5 is the arrival notification in case of movement of goods under temporary storage. This will only be required when goods are moved from one temporary storage facility to another.

The examples below show how TSF operators should manage their customs formalities.

  • Example 1

    Non-union goods are transported by sea into Dublin Port. The goods are going to a TSF (compound) in Dublin Port.

    The following steps should be completed in the AIS:

    The carrier lodges a combined G3/G4 [Presentation Notification (G3) and Temporary Storage Declaration (G4)] into the AIS. The G3/G4 Movement Reference Number (MRN) must be provided by the carrier to the TSF operator.

    Customs import declaration

    Where goods are released from temporary storage (within 90 days) using a customs declaration, the customs declaration must reference the MRN of the combined G3/G4.

  • Example 2

    Non-union goods are transported by air into Dublin Airport. The goods go into a TSF (transit shed) in Dublin Airport, but are then moved under a national transit to another TSF outside Dublin Airport.

    The following steps should be completed in the AIS:

    The carrier lodges a combined G3/G4 [Presentation Notification (G3) and Temporary Storage Declaration (G4)] into the AIS. The G3/G4 Movement Reference Number (MRN) must be provided by the carrier to the TSF operator. The operator of the TSF outside Dublin Airport, or their customs agent, must lodge a second G3/G4 into the AIS. This must be lodged on the arrival of the goods at that TSF.

    Customs import declaration

    Where goods are released from temporary storage (within 90 days) using a customs declaration, the customs declaration must reference the MRN of the combined G3/G4.

Note

Where goods are moving directly to an inland TSF under a simplified transit, a G3/G4 is required. This combined declaration should be lodged into the AIS by the TSF operator, or their customs agent, upon arrival of the goods at the TSF.

All goods entering or leaving a temporary storage facility must adhere to the relevant customs formalities.
