About this conversion
NKD 2025 is the activity classification used in Croatia. PKD 2025 is the equivalent system in Poland. 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.
