Declarant status & registry

Any importer of CBAM goods established in the EU — and indirect customs representatives acting for non-EU importers — must obtain authorised CBAM declarant status before importing. You apply electronically through the CBAM Registry, and the national competent authority of your Member State of establishment assesses the application. The authority grants the status where you: have not committed serious or repeated infringements of customs, tax, market-abuse or CBAM rules; demonstrate financial and operational capacity; are established in the Member State of application; and hold an EORI number. The decision takes effect once recorded in the CBAM Registry.

The annual CBAM declaration is submitted by the authorised CBAM declarant through the CBAM Registry. It is due by 30 September of the year following the year in which the goods were imported (Article 6 of Regulation (EU) 2023/956) — so the declaration for 2026 imports is due by 30 September 2027.

Once your application is authorised, you become an authorised CBAM declarant and the Commission assigns you a CBAM account number, which gives you access to the CBAM Registry. Access is managed through the EU-wide UUM&DS system; declarants reach the definitive system via either the CBAM domain or the customs domain, depending on the choice made by the national authorities. New UUM&DS profiles are required for the definitive registry, and national competent authorities assign these to existing declarants. Third-country operators can also be granted access via the Commission's EU-Access platform.
