About this conversion
ÖNACE 2025 is the activity classification used in Austria. TOL 2025 is the equivalent system in Finland. Both are national implementations of EU NACE Rev 2.1, so any 5th-digit subclass in one system can be traced back to a shared 4-digit EU class — and from there, forward into the other country's subclasses.
