What is the DUA?

The DUA (Documento Único Administrativo, the Single Administrative Document) is the customs declaration filed to import, export or place goods in transit with countries outside the European Union. It is not needed within the EU. In Spain it is filed electronically with the Spanish Tax Agency (AEAT).

When you need a DUA

The DUA is only filed for trade with non-EU countries (outside the EU customs territory): import, export or transit. It is not needed for trade within the EU, where the free movement of goods applies.

Legal basis and filing

The framework is the Union Customs Code (Regulation (EU) 952/2013) and its implementing regulations. In Spain it is handled by the Spanish Tax Agency (AEAT), with mandatory electronic filing using a digital certificate, within the EU's electronic customs systems.

If your transport crosses borders, Giormo keeps each shipment's documents organised and linked to the order. See it.
