You must present a Master Unique Consignment Reference (MUCR) or Goods Movement Reference (GMR) containing all the export declaration references (DUCR) when you arrive at the customs office of destination.
If you do not submit a MUCR or GMR, we wont be unable to print a Transit Accompanying Document (TAD). You should immediately contact the carrier or the declarants/agents and inform them of this. You must return to the inland border facility once you have a valid MUCR or GMR for the goods in your vehicle.
Do not travel to the departure gate.
