Customs clearance procedures play a central role in international logistics. As supply chains become increasingly global and security and compliance requirements continue to intensify, customs operations can no longer be treated as a simple administrative step. They are now part of structured, highly digitalized processes that are closely integrated with supply chain information systems.
In Europe, this transformation is driven by the Union Customs Code and the widespread deployment of electronic services. In France, the rollout of DELTA IE illustrates this shift toward fully paperless procedures, based on standardized data exchanges and higher requirements in terms of data quality and traceability.
Key international customs processes
Import declaration
The import declaration enables goods to be released for free circulation in the destination territory. Its purpose is to determine the applicable duties and taxes, as well as the commercial policy measures to be observed. Depending on the nature of the goods and their intended use, it may also lead to placement under one of the existing special procedures, allowing for suspension of duties and taxes under strict regulatory conditions.
In France, this procedure now relies on electronic declarations transmitted via the DELTA IE import system. This new format replaces the Single Administrative Document and requires a higher level of precision in the data submitted, particularly regarding tariff classification, origin of goods and identification of operators. Exchanges are designed for system-to-system flows, integrated with companies’ logistics and financial tools.
Export declaration
The export declaration governs the exit of goods from the customs territory. It enables authorities to control flows, secure trade and compile foreign trade statistics.
In France, the export procedure is also integrated into DELTA IE and relies on an exit monitoring system that confirms the effective departure of goods from the European Union. Consistency between declared data and physical flows is essential to avoid discrepancies and subsequent blockages.
International transit
Transit concerns goods moving under customs control between two points without immediate payment of duties and taxes. These procedures help facilitate international trade while safeguarding the fiscal interests of states.
Transit operations are based on international conventions and interoperable IT systems that ensure movement tracking, guarantee management and proper discharge of operations.
Regulations specific to each region or country
The European framework
The Union Customs Code forms the common regulatory foundation for EU Member States. It aims to harmonize customs rules while progressively digitalizing procedures. This framework promotes a more consistent approach to formalities, even though operational implementation remains the responsibility of each Member State.
French specificities
France has undertaken a major modernization of its customs tools with DELTA IE, which consolidates several former systems and introduces standardized messages for import and export. This evolution strengthens compliance and traceability but also requires operators to adapt their organizations and information systems.
Trade with third countries
Outside the European Union, formalities vary depending on the country and applicable trade agreements. Preferential origin rules, specific controls or documentation requirements in certain regions require continuous adaptability. Mastering these differences is essential to ensuring smooth international flows.
How to automate and simplify customs procedures
The digitalization of customs procedures relies on integrating declarations into existing supply chain systems. Moving from manual processing to automated flows, often through application interfaces, helps reduce lead times, improve data reliability and limit re-entry of information.
However, this automation requires rigorous centralization of customs master data, including tariff classifications, origin rules, special procedures and associated regulatory documents.
Specialized solutions such as COSMOS support this approach by structuring and orchestrating exchanges with customs authorities, while managing declarations, special procedures and regulatory archiving. The challenge is not only processing speed but also data consistency and the ability to demonstrate long-term compliance.
Common mistakes and how to avoid them
The digital transformation of customs procedures has introduced new sources of error. Inconsistencies between data from ERP, WMS or TMS systems and the formats expected by customs systems can lead to rejections or incomplete declarations. Insufficient management of return messages, particularly within DELTA IE, can also create discrepancies between the actual status of flows and their declared situation.
Special procedures represent another major point of attention. While they offer significant optimization opportunities, they require precise long-term monitoring. Properly opened procedures, such as inward processing, customs warehousing or temporary admission, can become sources of non-compliance if poorly managed, insufficiently documented or incorrectly discharged.
To mitigate these risks, companies must rely on single master data sources, automated controls and tools capable of ensuring consistency between declarations, physical flows and regulatory supporting documents.
Conclusion on international logistics
Customs clearance procedures have undergone profound transformation. They are no longer limited to administrative formalities but have become a critical digital process within international logistics. In a demanding and constantly evolving regulatory environment, mastering data, rules and tools is a key factor in reliability and performance. By structuring their practices around solutions aligned with European and national frameworks, supply chain departments can secure their flows while gaining agility and visibility.
