In each region, a regional chamber of commerce and industry is created by decree. The constituency of the regional chamber of commerce and industry is the region or, in Corsica, the jurisdiction of the territorial collectivity. Its head office is determined by decree, after consultation with the attached territorial and departmental chambers of Ile-de-France.
In regions where there is only one territorial chamber of commerce and industry, the same public establishment carries out the tasks assigned to the regional chambers of commerce and industry and the territorial chambers of commerce and industry. It is called a regional chamber of commerce and industry.
However, a regional chamber of commerce and industry encompassing two or more regions may be created by decree. Its registered office is determined by the decree of creation after receiving the assent of the territorial chambers of commerce and industry attached to it.
