How can importer become an “authorised CBAM declarant”?

From January 2025 onwards, CBAM declarants will be able to apply for the ‘authorised CBAM declarant’ status via the CBAM Registry. Their application will be processed by the National Competent Authority of the EU Member State where they are established. This status will become mandatory as of 1 January 2026 for the import of CBAM goods in the EU customs territory.
