Three U.S. grades are provided for rhubarb, U.S. Fancy, U.S. No.1, and U.S. No.2.

U.S. Fancy consists of stalks of rhubarb of similar varietal characteristics which are very well colored, fresh, tender, straight, clean, well trimmed, and not pithy.  They must be free from decay and free from damage caused by scars, freezing, disease, insects, or mechanical means.  The diameter of each stalk is not less than 1 inch, and the length is not less than 10 inches.

Other grades are the same except for the sizing, shape, and color
