Submit your samples

Step 1. Complete information on envelope

Before filling with your sample, complete your information on the front of the postage-paid envelope.

On the front of the envelope, write

  • the growing location
  • the variety of the sample
  • the class of the grain

If you received an envelope for a commodity you didn’t grow this year, cross out the commodity name and write the name of the commodity you are sending in the white space on the envelope.

Step 2. Pour grain sample into envelope

Pour a representative 800-gram sample of your grain up to the “fill” line printed on the inside of the envelope. Filling the envelope past the line can cause the envelope seams to burst.

Step 3. Remove backing paper from envelope

Remove backing paper from the envelope flap. Lift backing at the bottom right of the flap at the arrow and pull diagonally. The backing should remove in one piece to expose the glue area.

Step 4. Seal the envelope

Seal the flap firmly in place by pressing the entire flap down.

Step 5. Mail

Mail us your sample(s) as soon as you finish harvesting your crop or before November 30, 2023.
