Seed Regulatory Program

Seed sampling

Official sampling of seed commodities is provided by the Shipping Point 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
  • Seed location (e.g. warehouse, shipping facility, etc.)
  • 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 whenever possible.

​​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.
  • Have a person available at the warehouse to assist the sampler.
  • Check lot numbers, weights, and container counts before requesting sampling.
A minimum charge will be assessed if a sampler is unable to sample due to a lot not being accessible or prepared for sampling.
