CZ-NACE 09903 → CAE Rev 4 equivalent (Portugal)

About this conversion
CZ-NACE is the activity classification used in Czechia. CAE Rev 4 is the equivalent system in Portugal. 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.
