Hmm there ain't always border patrols.
Actually it's really easy to pass borders for just an minute extra flight.
I don't see why your should earn much more that way.
Maybe just add the proper trade routes (the ones who don't pass embargo's and such) of an particular ID on the ID information,
Not the best routes but just some average or under average routes.
And maybe some FLhook magic to notify transports that they are passing an Embargo with the wrong goods?
