CWC

CWC commonly refers to the Chemical Weapons Convention, an international arms-control treaty designed to eliminate chemical weapons and prevent their development, production, stockpiling, or use.

The treaty was negotiated under the auspices of the United Nations and opened for signature on January 13, 1993. It entered into force on April 29, 1997, after a sufficient number of states had acceded. The CWC established a comprehensive framework to prohibit chemical weapons and to provide for their destruction, as well as for the destruction of production facilities and related equipment. It also prohibits assistance, encouragement, or transfer of chemical weapons and related materials for prohibited purposes, while allowing certain peaceful industrial activities under strict regulatory oversight.

Implementation and verification are carried out by the Organisation for the Prohibition of Chemical Weapons (OPCW). States Parties are required to provide declarations on their chemical industries and dual-use facilities, and the OPCW conducts routine on-site inspections of facilities to verify compliance. The treaty also provides for challenge inspections and mechanisms to resolve suspected non-compliance. Destruction of existing stockpiles and related production capabilities is a central obligation, with monitoring to confirm completion.

The CWC has achieved broad international acceptance and is regarded as a cornerstone of global disarmament efforts in chemistry and related fields. While the vast majority of states are parties, universal adherence remains a continuing objective, with ongoing work to promote compliance, transparency, and assistance in implementing the treaty’s provisions.
