What is a national competent authority (NCA)?
Each Member State has designated a national competent authority (NCA), which will carry out the functions and duties as defined in Regulation (EU) 2023/956. In short, NCAs are responsible for checking the quality of the CBAM quarterly report (with support from the Commission) and engage, where needed, in a dialogue with reporting declarants. NCAs ultimately ensure compliance with CBAM rules and they may impose penalties. Finally, from 2025 onwards, for the definitive period, NCAs will grant the status of ‘authorised CBAM declarant’.
The list of NCAs is published and continuously updated on the dedicated CBAM webpage of the Commission: Carbon Border Adjustment Mechanism (europa.eu). The competent NCA is the NCA of the Member State of establishment of the reporting declarant.
