Certification and Seed Testing - VS04001

Seed Cerification is a statutory requirement for the majority of vegetable and agricultural species marketed in the European Union.
EC directives require that seed of these species must be officially certified as having met certain quality standards before it is marketed.
In England and Wales the day to day operation of Seed Certification is done by NIAB, on behalf of Defra.
NIAB operate the Official Seed Testing Station for England and Wales. They are authorised to carry out official tests on all species and categories of seed.
Testing work includes tests to assess varietal purity, species purity, seed health and germination capacity.
NIAB staff attend the International Seed Testing Association Congress and working group meetings in order to conribute to and keep up to date with current seeds testing issues.
A Guide to Seed Certification, and related documents), can be found at, along with details of contacts at the Plant Variety and Seeds Division who can answer queries.
