Official Seed Testing Station (OSTS)

The Official Seed Testing Station for Scotland (OSTS), SASA is the principle centre for seed testing and seed quality information in Scotland.  The OSTS is accredited to both the International Seed Testing Association (ISTA) and UKAS to ISO 17025:2005.  

The OSTS offers a wide range of laboratory tests that provide practical and reliable information for seed processors, merchants and growers on the quality of seed intended for sowing. Tests are made in carefully controlled conditions by trained and experienced analysts, using internationally approved methods. 

Our accreditation is limited to those activities described on our UKAS schedule of accreditation, see our [QA page].

Seed Certification

The OSTS undertakes some of the official testing of seed intended for certification.  Legislation allows for private seed testing laboratories to carry out official tests for certification provided they meet the licensing requirements defined in Seeds Regulations.  The OSTS monitors all official tests made in licensed seed testing stations.

Seed for Export

The OSTS issues Phytosanitary Certificates on behalf of Scottish Ministers for Seed Exports.
