Note to Supplement 1:

The numerical sequence of the “Schedule 1” Toxic Chemicals and Precursors is not consecutive so as to align with the December 23, 2019, consolidated textual changes to “Schedule 1” of the Annex on Chemicals to the Chemical Weapons Convention (CWC), which reflect the decisions adopted by the CWC Conference of the States Parties in November 2019.
