A Chemical Weapon is a chemical used to cause intentional death or harm through its toxic properties. Munitions, devices and other equipment specifically designed to weaponize toxic chemicals also fall under the definition of chemical weapons.

Herbicides

The prohibition of the use of herbicides as a method of warfare is recognised in the CWC Preamble. However, herbicides are not defined specifically in the Convention.

Herbicides that are intentionally used to harm humans or animals through chemical action on life processes could be considered a chemical weapon under the general purpose criteria.”
