The 1993 Paris Convention on the Prohibition of Chemical Weapons came into force on 29 April 1997 and definitively outlawed these weapons entirely.
In fact, this convention forbids any activity aimed at the development, production, acquisition, possession, storage, transfer and use of chemical weapons and materials connected with them. To this end, it introduces a specific control system that aims to monitor the production and use of certain mass-produced chemical substances, but which could also be used for the production of chemical weapons.
Under Italian law (Law no. 496/1995, as subsequently modified and amended), companies that produce, process, transform/consume certain chemical compounds are required to send a prior declaration to the Ministry of Economic Development.
