Organized industrial zone
An organized industrial zone () is a kind of special economic zone in Turkey. These zones may bring together related (OIZs for function) industries or just be a special zone for many industries (mixed OIZs). Not every industry is allowed to operate in organized industrial zones. Organized industrial zones are not duty-free, but there are considerable tax and location(by making related industries closer) advantages. OIZs are related to industrial parks in some countries.
