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.
