The department shall adopt rules governing the dockage on inferior grades, which shall apply in all executory contracts entered into after their adoption. If the purchase price depends on terminal weight or grade, the rules control the dockage insofar as dockage affects the purchase price. The department shall also provide for sample inspection of agricultural commodities, adopt rules governing sample inspection, and provide that the sample inspection, when made, is final.
