Multiple user accounts in the CBAM Transitional Registry can be associated with the same EORI number, provided they belong to employees of the responsible reporting declarant (i.e., the importer or indirect customs representative). However, only one user can edit a specific CBAM quarterly report in the CBAM Transitional Registry at any time.
Additionally, the reporting declarant can delegate access to the Transitional Registry to a “CBAM Service Provider,” who can complete the CBAM report on behalf of the reporting declarant. This delegation follows the “Employer-Employee” model, where the “Employer” is either the importer or an indirect customs representative, and the “Employee” is the “CBAM Service Provider.” It’s important to note that both the importer-employer and the provider-employee users must be configured by the Member States in UUM&DS, and the importer is responsible for delegating CBAM Declarant access to the Service Provider.
