The Chemical Weapons Convention

The Organisation for the Prohibition of Chemical Weapons in the Hague

The Chemical Weapons Convention (CWC) prohibits all development, production, acquisition, stockpiling, transfer, and use of chemical weapons. It requires each State Party to destroy chemical weapons and chemical weapons production facilities it possesses, as well as any chemical weapons it may have abandoned on the territory of another State Party.

The verification provisions of the CWC not only affect the military sector but also the civilian chemical industry, world-wide, through certain restrictions and obligations regarding the production, processing and consumption of chemicals that are considered relevant to the objectives of the Convention.

They will be verified through a combination of reporting requirements, routine on-site inspections of declared sites and short-notice challenge inspections. The Convention also contains provisions on assistance in case a State Party is attacked or threatened with attack by chemical weapons and on promoting the trade in chemicals and related equipment among States Parties.
