If the process is planned and the factory shall be established in an industrial complex, then an appropriate industrial complex has to be selected a priori. With the conclusion of a contract to move into the complex, it is at the same time accepted as an approval for factory establishment. Therefore, the construction and operation of the factory can follow.
If the factory is to be established in a location other than industrial complex, then the investor has to find out, if those locations are available for factory establishment and needs to get an approval from the competent local government before starting the construction and operation of the factory. The approval for factory establishment is compulsory for areas of more than 500m2, but it is also possible to receive an approval for areas of less than 500m2.
