AEV CBAM — common questions

Where do I submit my CBAM declarant application as a Luxembourg-based importer?+
All EU CBAM declarant applications are submitted through the central EU CBAM Registry at https://cbam.ec.europa.eu/authorised-declarant/, regardless of which member state your business is established in. AEV reviews and approves applications from importers established in Luxembourg — the submission portal itself is shared across the EU.
How do I contact AEV about CBAM?+
AEV's official site (linked above) is the canonical channel for current contact details. Email addresses and phone numbers change as the agency restructures; we deliberately don't republish them here so you reach the live source. The European Commission also maintains the official member-state NCA list at taxation-customs.ec.europa.eu/carbon-border-adjustment-mechanism_en.
Does AEV charge a fee for CBAM declarant authorisation?+
Regulation (EU) 2023/956 does not impose an EU-wide fee for declarant authorisation. National fees, where they exist, are published on each NCA's own site — most member states publish no fee for the authorisation step itself. Verify on AEV's official site (linked above) before assuming.
In which language must I submit my CBAM application via AEV?+
The central EU CBAM Registry accepts submissions in English. Some member states require supporting documents (verifier reports, EORI evidence, etc.) translated into Lëtzebuerg; AEV publishes the language requirements for Luxembourg on its CBAM page. Verify before assembling your application package.
