In the event of incompatibility between certain NACE Rev. 2 headings and the national economic structure, the Commission may authorise a Member State to use an aggregation of NACE Rev. 2 headings in a specific sector.
To obtain such an authorisation, the Member State concerned must provide the Commission with all the necessary information to consider its request. The Commission shall decide within three months.
However, notwithstanding the provisions of paragraph 2, such an authorisation shall not entitle the Member State concerned to subdivide the aggregated headings in a way different from NACE Rev. 2.
