Market Access Certification and Inspection

Seed sampling

Official sampling of seed commodities is provided by the Commodity Inspection Program to accomplish the following:

  • Meet the demands of importing countries that require testing for Phytosanitary Certificates and various other export requirements
  • Provide unbiased representative samples for testing seed quality and condition
  • Provide authorized seed samples to grant endophyte tags, sod quality tags, and International Seed Testing Association (ISTA) orange tags
​​​The official sample can be delivered to the Oregon Department of Agriculture (ODA) laboratory, the Oregon State University (OSU) laboratory, or certain private seed laboratories; or returned to the customer.

Sample request

To request sampling, submit a seed sampling request form with the following information:

  • Company name for billing purposes

  • Lot identification
  • Total number of pounds/kilograms
  • Number of containers
  • Sample delivery location
  • Country or state of seed origin
  • Type of tests requested 
In the Willamette Valley, samples are pulled within one working day of the request.

Preparing seed lot for sampling

  • Each container/bag must be identified with lot numbers.
  • Containers/bags must be no more than eight feet high (two high) and readily available for sampling without posing risks to the sampler.

Sampling tips

  • Notify the warehouse and make sure seed is available and accessible before requesting sampling services.
  • Fax sample requests before 9:00 am for same day service in the Willamette Valley.
  • Have a person available at the warehouse to assist the sampler.

A minimum charge will be assessed if a sampler is unable to sample due to a lot not being accessible or prepared for sampling.
