The 1993 Paris Convention on the Prohibition of Chemical Weapons came into force on April 29, 1997 and finally sanctioned the complete ban on such weapons.
As a matter of fact, this convention prohibits any activity aimed at the development, production, acquisition, holding, preservation, transfer and use of chemical weapons and connected materials.
To this end it introduces a specific control system that seeks to monitor the production and use of certain substances for broad civil consumption, but that may be potentially also used for the production of chemical weapons.
Based on Italian regulations in force (law no. 496/1995 as amended and added), the companies that produce, process, transform/consume certain chemical compounds are required to send a preventive declaration to the Ministry for Economic Development.
