CAE Rev 4 37002 → WZ 2025 equivalent (Germany)
Portugal's national activity classification (CAE Rev 4) shares its 4-digit backbone with the EU NACE Rev 2.1 standard. We use that backbone to surface the equivalent WZ 2025 subclass(es) used in Germany.

About this conversion
CAE Rev 4 is the activity classification used in Portugal. WZ 2025 is the equivalent system in Germany. 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.
