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.

The Handbook on Chemicals 2017 includes the updated HS codes that will be effective from 1 January 2017 and covers 1800 scheduled chemicals declared by States Parties since 1997 up to 2014. 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 the 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.

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’.
