Participating in the CBMs






The CBM Form

Please find below MS Word versions of the blank CBM form, extracted from BWC/CONF.VII/7, in all official BWC languages:


The CBM Guide

This guide has been prepared by the United Nations Office for Disarmament Affairs with the support of the European Union, as part of the European Union’s 2008 Joint Action in support of the BWC and its 2012 Council Decision in support of the BWC.

The aim of the guide is to provide practical advice and guidance to officials responsible for preparing CBM submissions. The guide includes:
  • Background information on the CBM process,
  • General advice for preparing to participate in the CBMs, and
  • Detailed guidance on gathering the specific information required for each form.

This guide is intended only as a practical aid and has no formal status; please refer to the decisions of the respective Review Conferences for the formal requirements of the CBMs. The guide includes some suggestions for providing information in addition to that required by the CBM forms. These are only suggestions and are not intended to imply or confer any additional obligations on States Parties.

The guide is available free to States Parties, and is available below in each of the six official
languages of the United Nations (Arabic, Chinese, English, French, Russian and Spanish):

Advice on completing the CBM Form

Completing the CBM forms takes time, especially for the first year of participation. As each country's system of government is different, here are some general suggestions:
  • Start early: the CBM deadline is April 15. Collecting the necessary information typically requires contacting several different government ministries and agencies, a process which could take a long time.
  • Use information that has already been compiled: some of the information required for the CBMs may also be required for other purposes, such as reports to the WHO or those mandated by Security Council Resolution 1540.
  • Be clear: if there is nothing to declare for a particular measure, say so, rather than leaving the form for that measure blank. Similarly, if there is incomplete information, or information that will be provided later, say so on the form. Remember that the purpose of the CBMs is to increase transparency, therefore incomplete information is better than none.

Below are some informal suggestions for completing each of the measures:

If your country has conducted any offensive and/or defensive biological research and development programmes since 1 January 1946, it should be described on this form. The amount of detail to be provided is at the discretion of the State Party, but in the interest of transparency, consider providing as much information as possible.

Submitting the CBM Form

The preferred submission option is an electronic CBM return (as a Microsoft Word, RTF, or PDF document). These can be sent to bwc@unog.ch. All e-mail submissions will be acknowledged.

A hard copy with a note verbale as the cover can be sent from your permanent mission in Geneva, either by post or by fax, to:

BWC Implementation Support Unit
Office for Disarmament Affairs (Geneva Branch)
Room C.115-117, Palais des Nations
1211 Geneva 10

Fax: +41 (0)22 917 04 83

Options for publication

Since 2007, CBM submissions are published in the restricted area of this website (accessible only to States Parties) unless the submitting State Party requests otherwise. Please inform the ISU if you do not want your CBM published on the secure website. Any CBMs that are not published on the website will be circulated to States Parties on CD-ROM. Some States Parties have opted to make their CBM returns available on the public section of this website. These can be found on the CBM Returns page.

Missed the deadline?

CBM returns are due by 15 April each year. If you miss this deadline, please do still submit the return as soon as you can: it is better if you submit a CBM after the deadline than not at all. If your CBM is received too late for inclusion in the paper version of the annual ISU report, it will be issued as an addendum.

Questions or comments on the CBM Form?

If you have problems or questions during the CBM process, please contact the ISU and we will do our best to help: see the contact page for details.

The ISU is also interested in receiving perspectives on any obstacles to participating in the CBMs, as well as suggestions for improvements to the current system. Such ideas can be fed into ongoing efforts to facilitate participation in the CBMs and improve their utility to States Parties.
