GRADES & GOOD ARRIVAL
Generally speaking, the percentage of defects shown on a timely government inspection certificate should not exceed the percentage of allowable defects, provided: (1) transportation conditions were normal; (2) the USDA or CFIA inspection was timely; and (3) the entire lot was inspected.
|U.S. Grade Standards||Days Since Shipment||% of Defects Allowed||Optimum Transit Temp. (°F)|

• Bruising is scored as a defect, against the U.S. No.1 grade when it causes a slight discoloration and exceeds an area of 3/8-inch in diameter; or if the bruise causes an indentation or discoloration of the flesh deeper than 1/8 inch
• If the fruit is in storage, moisture may evaporate, leading to shriveling—shriveling found on shoulders or at the stem end is scored as a defect against the U.S. No.1 grade when it exceeds an area of 10% of the surface; shriveling is always scored against the tolerance for serious damage
• Kiwifruit is one of the few commodities with a maturity requirement for the U.S. No.1 grade; soluble solids taken from 15 randomly selected fruit must meet a minimum of 6.5% brix.
