Found on another site.
The import duties don’t necessarily apply to where the item is coming from but where it was manufactured and sometimes what features it has.
For example you might have to pay a duty on a Chinese scope and not on a German scope. There is a whole database maintained by customs that is supposed to be updated with the latest legislation. The importer or their broker is supposed to provide the correct item code to customs and assuming they agree with your assessment that will determine if and how much duty you need to pay.

How are you supposed to make sense out of all of that nonsense? How many days of research to determine the duty?
I found tariffs on Chinese scopes, but I have not found anything yet for Germany.
