Introduction
Starting June 19, 2025, the European Union will roll out the AIS/IMPORT PLUS system—a major step in the update of import procedures across member states. This upgrade replaces the existing AIS/IMPORT framework and introduces fully electronic customs declarations in line with the EU’s Union Customs Code (UCC).
The transition is part of the EU’s broader effort to harmonize and digitize cross-border trade operations, supporting faster customs processing, improved data accuracy, and stronger regulatory compliance.
Production Pilot Phase
Prior to the official launch, EU member states are expected to conduct production pilot tests of the AIS/IMPORT PLUS system. These pilots allow companies to trial declarations in real conditions. A key consideration: there will be no automatic data migration from the current systems, so all existing operations must be closed before migration.
What’s New in AIS/IMPORT PLUS?
1. Integration with Key EU Systems
The new system is fully integrated with other EU-level platforms such as:
- NCTS2 PLUS (transit)
- RPS (risk analysis)
- ISZTAR4 (tariff classification)
Communication and updates will be centralized via each country’s customs portal (e.g., PUESC in Poland).
2. Changes in Temporary Storage and Payment Procedures
Updates to temporary storage declarations (DSK) and payment mechanisms will streamline logistics while aligning with EU customs standards.
3. Discontinued Simplified Procedure for Certain Goods
Under AIS/IMPORT PLUS, simplified declarations will no longer be permitted for goods requiring:
- Sanitary inspection
- Phytosanitary checks
- Veterinary controls
- Commercial quality assessment (especially agri-food products)
Key Technical and Procedural Changes
1. Change of message names
The names of messages sent after customs clearance will change. For example, the current message ZC299 will be replaced by ZC429
2. Entity Identification via EORI Only
The identification of the entity data of the Importer/Buyer will change. In customs documents, the identification of entities will be based solely on the EORI number (NIP, REGON). Verification and possible update of data in PUESC/EORI is required, especially if there have been changes in the company address or legal form. Failure to update this information may result in outdated importer data appearing on the customs document
3. Structure of customs declaration numbers
The structure of customs declaration numbers will be updated under AIS/IMPORT PLUS.
