Schedule 1 substances
, in the sense of the Chemical Weapons Convention
, are chemicals which can either be used as chemical weapons themselves or used in the manufacture of chemical weapons and which have no, or very limited, uses outside of chemical warfare.
These may be produced or used for research, medical, pharmaceutical or chemical weapon defence testing (called "protective testing" in the treaty) purposes but production above 100 grams per year must be declared to the OPCW
in accordance Part VI of the "Verification Annex". A country is limited to possessing a maximum of 1 tonne of these materials.
They are sub-divided into Part A substances, which are chemicals that can be used directly as weapons, and Part B which are precursors useful in the manufacture of chemical weapons. Examples are mustard
agents, and substances which are solely used as precursor chemicals in their manufacture. A few of these chemicals have very small scale non-military applications, for example minute quantities of nitrogen mustard
are used to treat certain cancers
Chemicals which can be used as weapons, or used in their manufacture, but which have legitimate applications as well are listed in Schedule 2
(small-scale applications) and Schedule 3
(large scale applications).
