Customs digitalisation, explained with transparency.
What happens behind the scenes of every customs clearance, why a digital signature and compliant preservation are necessary, and how robust infrastructure is your first line of fiscal defence.
If, when analysing the costs of your customs operations, you have noticed items relating to «electronic fees», «digital signatures» or «statement management», it is important to understand exactly what you are funding.
With the definitive shift to «Customs 4.0», the import-export process has left paper behind. Today, every customs operation is a complex exchange of certified digital data with the AIDA system (Automazione Integrata Dogane Accise). In this guide we explain, with full transparency, what happens behind the scenes of every clearance and why a solid infrastructure is your first line of fiscal defence.
It is not «just a signature»: the AIDA ecosystem.
It is often assumed that the technical cost of a customs declaration is linked exclusively to the application of a digital signature. In reality, the signature itself has a marginal cost. What companies bear is the cost of the entire infrastructure required to communicate with government servers.
To submit a declaration, completing a PDF is not sufficient. The system requires:
Generation of XML files
Complex files with hundreds of logical fields that must pass the syntactic validation checks of the Italian Customs and Monopolies Agency (ADM).
Accredited transmission channels
Secure, certified connections to ensure that data travels without interruption or tampering.
Asynchronous message management
The system must remain constantly «listening» in order to download technical acknowledgements, control outcomes and, above all, goods release messages.
The end of the paper customs declaration and the new statements.
Since 2022, the classic paper «customs declaration» (the DAU) has been abolished. In its place, the system generates data flows from which specific digital documents must be extracted:
Accounting statement
The fundamental document for deducting import VAT in accounting records.
Summary statement
The summary of duties and charges paid.
Export Accompanying Document (EAD)
The irrefutable digital proof that goods have left EU territory, vital for avoiding penalties relating to VAT non-taxability.
The retrieval, validation and provision of these files require software automations running in the background for every single declaration.
The Electronic Dossier and Preservation: why 10 years?
Every customs declaration is accompanied by supporting documents (commercial invoices, packing lists, certificates of origin). All of this flows into the Electronic Dossier. But for how long must this data be preserved in accordance with the law?
A clear distinction must be made between customs regulations and tax regulations:
The customs rule: 3 years
The Union Customs Code (UCC) provides for a basic retention obligation of at least 3 years for strictly customs-related controls (extendable in the event of audits).
The tax rule: 10 years
Customs statements and the invoices linked to them are, to all intents and purposes, accounting documents. Article 2220 of the Italian Civil Code and Italian tax regulations require the retention of accounting records for 10 years.
Why do we aim for the 10-year standard?
To guarantee you complete security. An audit by the Italian Revenue Agency (AdE) on deducted VAT may arise long after customs clearance. Having an archive in AgID-compliant Legally Compliant Digital Preservation for 10 years means that your documents are unalterable, secure, timestamped and always ready for inspection, protecting you from any future tax dispute.
The value of control over your data.
The technical costs associated with the digital management of customs declarations do not simply cover «a software package», but fund your corporate compliance.
Relying on robust infrastructure means transforming a bureaucratic burden into a strategic advantage: having absolute certainty that your customs flows are correct, legally unassailable and retrievable at any time, today as well as ten years from now.
