Digital Transformation in European Customs: H1 System Mandatory as of October 15, 2025

Starting October 15, 2025, Spain will require all import declarations to be submitted using the new H1 electronic customs system, replacing the traditional Import DUA as part of the EU’s push for digital, harmonized customs procedures. This change affects all importers and logistics operators, who must update their IT systems and processes to comply with the new structured electronic format and enhanced data requirements. GEODIS is committed to guiding clients through this transition to ensure compliance and operational continuity.
