Customs Regimes in the EU

21. 5. 2025

The entry or exit of goods across the borders of the European Union is governed by a set of procedures, regulations and legal instruments, which are collectively referred to as customs regimes. These regimes form the backbone of international trade, protect the economy, security, health of the population and financial interests of the Member States and the Union itself. In this glossary you will find detailed definitions of the main customs regimes, explanations of the legal framework, technical requirements and practical aspects of customs procedures in the EU.

Basic Legal Framework for Customs Procedures in the EU

Union Customs Code (Union Customs Code – UCC)

  • Main legislative instrument: Regulation (EU) No 952/2013, the so-called Union Customs Code (UCC).
  • Purpose: Modernization, harmonization and digitalization of customs rules across the EU.
  • Implementation: Commission Implementing Regulation (EU) 2015/2447 and other delegated acts establish specific rules and ensure uniform application of the code.
  • Currency: Regularly updated, the last significant change 2024/635 (e.g. evidence of customs status of Union goods, amendments to transit regimes).
  • Objective: Transition to a paperless, fully electronic customs environment by 2025 at the latest.

Key principles:

PrincipleMeaning
Legal certainty and uniformityCustoms rules apply equally in all Member States.
ElectronizationTransition from paper documents to electronic systems.
SimplificationUniform and clear procedures for businesses and customs officials.
ProtectionEmphasis on security, market protection, consumer protection and EU budget protection.
Preferential treatmentFaster procedures and benefits for trusted companies (AEO).

Key Concepts: Customs Union, Customs Territory, EORI

EU Customs Union

  • Definition: A single commercial territory without internal tariffs, with a uniform tariff schedule towards third countries.
  • Exceptions: Specific territories (e.g. Monaco, special regime for Northern Ireland after Brexit).
  • Objective: To facilitate trade, ensure equal conditions, protect consumers and the environment, contribute to the EU budget.

Customs Territory of the Union

  • Scope: Territory of all Member States + some associated territories.
  • Exceptions: E.g. Canary Islands, special agreements with some micro-states (Andorra, San Marino).
  • Consequence: UCC rules and the common tariff schedule apply in the customs territory.

EORI (Economic Operators Registration and Identification number)

  • Significance: Mandatory registration for anyone wishing to submit customs declarations in the EU.
  • Assigned by: Customs authority of the Member State where the entity is established or has a place of business.
  • Use: Identification in electronic systems, required for importers, exporters, carriers and intermediaries.
