List Of Schedule 2 Substances (CWC)

Schedule 2 substances, in the sense of the Chemical Weapons Convention, are chemicals that can either be used as chemical weapons themselves or used in the manufacture of chemical weapons but that have small-scale applications outside of chemical warfare and so can be legitimately manufactured in small quantities. An example is thiodiglycol, which can be used in the manufacture of mustard agents but is also used as a solvent in inks.

Manufacture must be declared as their production is subject to declaration to the OPCW per Part VII of the "Verification Annex", and they may not be exported to countries that are not party to the Convention

As with the other schedules, 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.

Chemicals that can be used as weapons, or used in their manufacture, but that have no, or almost no, legitimate applications as well are listed in Schedule 1, whilst Schedule 3 is used for chemicals that also have widespread industrial uses.
