Handbook on Chemicals

The Handbook on Chemicals is an important tool which aims at assisting States Parties in the identification of individual chemicals covered by the three Schedules in the Annex on Chemicals of the Chemical Weapons Convention.

The Handbook on Chemicals is a part of the Declarations Handbook (Appendix 2 of the Declarations Handbook). The Handbook on Chemicals is an important tool which aims at assisting States Parties in the identification of individual chemicals covered by the three Schedules in the Annex on Chemicals of the Chemical Weapons Convention.

The Handbook is updated and revised on a regular basis to incorporate the new scheduled chemicals that States Parties will declare in the future as well as any changes in the identifiers such as Chemical Abstracts Service Registry Numbers (CAS RN) and Harmonized System Codes (HS codes) assigned to scheduled chemicals.

This 2018 version of Handbook on Chemicals supersedes the previous 2017 version and includes additional 260 scheduled chemicals declared from 2014 up to 2017.

The Handbook on Chemicals version 2018 covers 2060 scheduled chemicals declared by States Parties from 1997 to 2017. The chemicals are indexed in ascending order of schedule number (Schedule 1, Schedule 2 and Schedule 3); entry number in each Schedule (e.g. 2B04, 2B05, 2B06, etc.); and CAS RN or OPCW Key.

Although this Handbook on Chemicals contains information on all scheduled chemicals declared to the Technical Secretariat, it is not a comprehensive list of all declarable scheduled chemicals, and as such should only be used as a tool to assist in the identification of chemicals. The OPCW has made available a more exhaustive database OPCW Online Scheduled Chemicals Database containing up to 34500 scheduled chemicals, including 2060 chemicals detailed in this Handbook.

Chemical Names have been created in accordance with the Rules for Naming Compounds in the OPCW Central Analytical Database (OCAD) ’ and OPCW Key Codes created (where CAS RN is not available) in accordance with the Guidelines for Assignments of the Chemical Key Codes to the Scheduled Chemicals’.
