CBAM Transitional Registry
The Commission has developed the CBAM Transitional Registry to help importers perform and report as part of their CBAM obligations.
Note: The link provided is accessible solely to importers who have been duly registered by the relevant National Competent Authorities. If you haven't yet registered and you wish to access the registry, kindly reach out to the NCA of your respective Member State.
Access to the Transitional CBAM registry should be requested through the National Competent Authority (NCA) of the Member State in which the importer is established.

Authorisation Management Module
As of 31 March 2025, a new section of the CBAM Registry allows importers and indirect customs representatives to apply for the status of authorised CBAM declarant in the Member State of establishment, which is independently from the where the goods are imported to. A list of the national competent authorities can be found on this website in the section “How to access the transitional registry”.
The section to be used is the Authorisation Management Module (AMM) (this link will be accessible on 31 March 2025). The AMM encompasses features related to CBAM Authorisations. This module facilitates the entire process, from the initial authorisation requests submitted by applicants to the consultation process between competent authorities and the Commission, culminating in a decision to grant or refuse the CBAM authorisation.
Key functionalities of the AMM include:
- Capturing all relevant authorisation information, including the required guarantees.
- Supporting the interaction between CBAM Declarants and competent authorities.
- Managing workflows between the competent authorities and the Commission, as well as back-office operations within both entities, to support the authorisation process.

Access for non-EU installation operators
As of January 2025, a new portal section of the CBAM Registry allows installation operators outside the EU to upload and share their installations and emissions data with reporting declarants in a streamlined manner, instead of submitting it to each declarant separately.
The portal allows operators to ensure the confidential treatment of business-sensitive data. Reporting declarants are then able to automatically populate their CBAM reports with this emissions data in order to comply with their reporting obligation.
CBAM declarants can retrieve the information provided by non-EU installation operators in the Transitional Registry. A new functionality in the “Emissions” tab allows declarants to “Search in Third Country Installations registry” and access the respective installation and emissions data from there.
For this to work, CBAM declarants need to share their EORI number with the supplier outside the CBAM Registry. In a future update, operators will be given the option to share their information with all interested declarants.
To become a Registered Operator, non-EU installation operators need to follow the steps outlined in the following e-learning modules and guidance documents.
| Video tutorial | Description |
|---|---|
| Manage registration requests, requests for change, parent company details and export list of installations | This training video series consists of 10 sessions covering the comprehensive workflow for operator request management and system interaction with the O3CI (Operators of Third Country Installations) platform. The series will help operators (with standard and administrative user roles) to navigate in O3CI platform, create, save, submit, correct, and resubmit requests following Commission’s feedback. Additional functionality covers parent company management and the ability to search and export installation data. The sessions presented follow a logical progression from initial registration to advanced features, allowing users to follow either a sequential path or select specific topics, as needed. |
| Manage emissions, operator and installation data disclosure and export list of emissions | This training video series consists of 8 sessions covering the complete workflow for managing emissions information and disclosing operator / installation data to the Transitional Period system via the O3CI platform. The series will help operators (with standard and administrative user roles) to add, search, view, edit, and delete emissions data. Users will learn how to control which operator and installation data are accessible to the public through the disclosure management features and add or edit the list of declarants that this information will be disclosed to. The series also highlights important functionality for information retrieval allowing users to export comprehensive emissions lists. The sessions presented follow a logical progression from adding, viewing, editing, deleting emission information to disclosure information management, allowing users to follow either a sequential path or select specific topics, as needed. |
| Search, Navigate and view details of operator, installations and supporting documents | This 8-minute training video demonstrates how to effectively search, navigate, and access detailed information about operators, installations, and supporting documentation within O3CI portal. The video will help operators to learn how to utilize the platform's pagination, sorting and filtering functionality to locate specific installation using various criteria such as installation id, installation name, country and city of establishment. This essential navigation training ensures authorized operators can efficiently locate required information in other functionalities of the O3CI portal such as emission management. |

Reporting
CBAM reporting declarants will find in the CBAM Transitional Registry User Manual an XSD file describing the full structure of the CBAM quarterly report, as well as a sample ZIP file, which may be uploaded in the Registry to fill in automatically the quarterly report’s data. For convenience, the XSD and the sample ZIP files can also be downloaded below.
In addition, the Commission has prepared a specific guidance document for declarants, which outlines the functioning and step-by-step use of the “request delay” options in the CBAM Transitional Registry. The CBAM Transitional Registry is continuously enriched with IT updates and fixes (see attachment below for the latest update).

Furthermore the “Error Messages Glossary” tab is providing guidance on how the user can overcome the validation error messages displayed whenever a validation rule/condition is triggered due to an issue with the field values filled/selected by the user.
To help declarants to prepare for the CBAM definitive regime, the Commission has prepared a user manual for the CBAM Registry for the CBAM Definitive phase.
