CBM Guide


Filling out the form

The CBMs report consist of six measures or forms
  • CBM A
    Part 1: Exchange of data on research centres and laboratoriesPart 2: Exchange of information on national biological defence research and development programmes
  • CBM B
    Exchange of information on outbreaks of infectious diseases and similar occurrences caused by toxins
  • CBM C
    Encouragement of publication of results and promotion of use of knowledge
  • CBM E
    Declaration of legislation, regulations and other measures
  • CBM F
    Declaration of past activities in offensive and/or defensive biological research and development programmes
  • CBM G
    Declaration of vaccine production facilities
In addition to these six forms, there is also a cover page declaration, sometimes referred as “Form 0”. This contains a list of the CBMs with a choice of answers for each measure: “Nothing to declare” or “Nothing new to declare” and asks for the “Year of last declaration if nothing new to declare”. It also requires details of the submitting State Party, including the National Point of Contact. All CBMs received since 1987 are available to all States Parties on the eCBM platform. States Parties have the option to make their CBM submissions either publicly available or restricted to other States Parties only. States Parties are requested to inform the ISU about their choice when submitting their CBMs.

The annual deadline for CBM submissions is 15 April. The information provided should cover the previous calendar year (for example, a CBM covering data for the calendar year 2023 needed to be submitted no later than 15 April 2024). This deadline should be met whenever possible. Nevertheless, you can, if absolutely necessary, submit your CBM at any time, even after the deadline. Making a late submission is much better than failing to make a submission at all.
