BIS administers the industry compliance program for the Chemical Weapons Convention (CWC), an international treaty that bans the development, production, stockpiling, and use of chemical weapons among its signatories and provides for an extensive verification regime to ensure adherence to its terms. BIS also actively engages other CWC State Parties and the Technical Secretariat of the Organization for the Prohibition of Chemical Weapons (OPCW) to ensure that the provisions of the CWC are being implemented in a rigorous, analytically sound, and equitable manner among all State Parties.
