Seed sampling services

Official sampling

Reliable independent third-party seed sampling for the domestic and international markets.
Commodity Inspection Program provides official seed sampling to:
  • meet the import requirements, such as phytosanitary certificates of countries importing Oregon seed.
  • provide unbiased, representative, samples for testing seed quality and condition.
  • provide authorized seed samples for endophyte tags, sod quality tags, and International Seed Testing Association (ISTA) orange tags.
The official sample can be delivered to the ODA laboratory, the OSU laboratory, certain private seed laboratories, or returned to the customer.

Sampling tips
  • Notify the warehouse and make sure seed is available and accessible before requesting sampling services.
  • Fax sample requests before 9am for same day service in the Willamette Valley.
