The OSIA & COST seed laboratory closed on June 1, 2022. The OSIA office is now located at Ohio Foundation Seeds, Inc., 11491 Foundation Rd, Hartford, OH 43013. Our field inspection and tagging services will continue as normal.

OSIA recommends sending your samples to other nearby AOSCA agency seed labs (listed below). All Certified, Identity Preserved, and Quality Assurance seed lots will still need a varietal purity and complete test performed by one of these labs. A copy of all final test results needs to be sent to OSIA.
