List of Schedule 2 substances (CWC)

Encyclopedia : L : LI : LIS : List of Schedule 2 substances (CWC)

Schedule 2 substances, in the sense of the Chemical Weapons Convention, are either

toxic enough to be used as chemical weapons, or
precursors of other listed substances.

These chemicals also have no large-scale industrial uses: however, they may have legitimate small-scale uses. Their production is subject to declaration to the OPCW as per Part VII of the "Verification Annex", and they may not be exported to countries which are not party to the Convention.

Guidelines for Schedule 2

The following criteria shall be taken into account in considering whether a toxic chemical not listed in Schedule 1 or a precursor to a Schedule 1 chemical or to a chemical listed in Schedule 2, part A, should be included in Schedule 2:

It poses a significant risk to the object and purpose of this Convention because it possesses such lethal or incapacitating toxicity as well as other properties that could enable it to be used as a chemical weapon;
It may be used as a precursor in one of the chemical reactions at the final stage of formation of a chemical listed in Schedule 1 or Schedule 2, part A;
It poses a significant risk to the object and purpose of this Convention by virtue of its importance in the production of a chemical listed in Schedule 1 or Schedule 2, part A;
It is not produced in large commercial quantities for purposes not prohibited under this Convention.
