Adopted in September 2026, the new Union Customs Code (UCC) initiates the most extensive transformation of the customs union since 1968. At the heart of this overhaul is the gradual replacement of traditional customs declarations with a system based on the continuous flow and sharing of data.
Behind this technological modernization lies a profound overhaul of corporate legal responsibilities and European governance.
The end of the form: moving toward a flow-based logic and the “Data Hub”
The most visible change brought about by the reform lies in the gradual phasing out of traditional customs declarations in favor of a centralized infrastructure: the EU Customs Data Hub.
From forms to data streams: Eventually, operators will no longer submit declarations in the traditional sense. Instead, they will make their data available on an ongoing basis as it becomes ready, and subsequently simply notify the authorities that the goods have been made available.
A single entry point: The Data Hub is intended to replace the roughly one hundred fragmented national IT systems currently used by the Member States.
The deployment schedule:
- July 2028: Mandatory for the e-commerce sector.
- March 2031: Opening on a voluntary basis for all operators.
- March 2034: Mandatory use for all import and export flows.
According to European Commission estimates, this digital transition is expected to generate substantial savings, valued at nearly €2.3 billion per year in operational costs for member states and €2.58 billion in administrative costs for businesses.
Strengthened and centralized governance in Lille
The reform also marks a major institutional turning point with the creation of the European Union Customs Authority (EUCA), which will be headquartered in Lille.
Endowed with legal personality and its own budget, this new entity will be responsible for operating the Data Hub and managing risk analysis at a European level. While physical, on-the-ground inspections will remain the responsibility of national authorities, the targeting of these checks will now be handled at the European level enabling more effective detection of fraud or discrepancies (regarding value, origin, or classification) that recur across multiple EU member states.
Increased responsibilities for companies from 2027 onwards
While the 2034 deadline for a fully digital system may seem far off, a major part of the reform will take effect as early as September 21, 2027:
- Legal establishment of the concept of an “importer”: The Code introduces a clear definition of an importer, described as the person with the authority to decide to bring goods into the Union. This party assumes responsibility for duties and taxes, as well as for product compliance (covering areas such as safety, the Carbon Border Adjustment Mechanism—CBAM, deforestation, and forced labor).
- Impact for customs representatives: In the case of indirect representation, the liability of the representatives is broadened, necessitating a careful review of contracts and mandates on a flow-by-flow basis.
- The “Trust & Check Trader” status: Designed to reward the most compliant operators (supplementing the existing Authorized Economic Operator—AEO—status), this new designation will allow companies to provide certain additional data after the release of goods and, eventually, to authorize the release of goods themselves. In exchange, the company must grant customs authorities real-time access to its records and supply chain.
What are the practical implications for customs and logistics departments?
For customs brokers and corporate logistics departments, the profession is shifting from simple document entry toward data governance and ensuring data reliability.
The quality of information (tariff classification, origin, value, regulatory compliance) must be ensured from the outset, as the overall reliability of a company’s information system is now the foundation for the trust placed in it by customs authorities.
In summary: The period during which current national systems and the future Data Hub will coexist promises to be challenging. It is in the best interest of companies to audit their data repositories and internal processes now, in order to ensure a smooth transition.
Given the growing complexity of regulatory obligations, industry experts like Eurotax play a pivotal role in securing corporate operations.
