Grain Inspection

​​​The Grain Inspection Unit of The Wisconsin Department of Agriculture, Trade and Consumer Protection conducts inspection, grading and related services. The unit is based in Superior. It conducts inspection, weighing, and grading services in accordance with guidelines established by and under the delegated authority of the Federal Grain Inspection Service. FGIS is a unit of the Agricultural Marking Service, which is an agency housed within the United States Department of Agriculture.

Information about Submitting Samples

For a full grade/inspection we require 1000 to 1250 grams. For a protein test we need approximately 600 grams. For a Falling Number determination we need approximately 250 grams. For a DON or vomitoxin test we need approximately 200 grams. For an aflatoxin test we need approximately 10 pounds. These can be sent directly to our office at 404 Tower and we can usually give results the same day we receive the sample. Each sample should have an ID attached so the customer will recognize the results when received. The samples should also be accompanied by an address/fax number where the results can be sent.
