Grades 

§51.3115 U.S. No. 1. 

"U.S. No. 1'' consists of strawberries of one variety or similar varietal characteristics with the cap

(calyx) attached, which are firm, not overripe or undeveloped, and which are free from mold or

decay and free from damage caused by dirt, moisture, foreign matter, disease, insects, or

mechanical or other means. Each strawberry has not less than three-fourths of its surface

showing a pink or red color. 

(a) Size. Unless otherwise specified, the minimum diameter of each strawberry is not less than

three-fourths inch. 

(b) Tolerances. In order to allow for variations incident to proper grading and handling the

following tolerances, by count, are provided as specified: 

(1) For defects. Not more than 10 percent for strawberries in any lot which fail to meet the

requirements of this grade, but not more than one-half of this tolerance, or 5 percent, shall be

allowed for defects causing serious damage, including therein not more than two-fifths of this

latter amount, or 2 percent, for strawberries affected by decay. 

(2) For off-size. Not more than 5 percent for strawberries in any lot which are below the

specified minimum size. 

§51.3116 U.S. Combination. 

"U.S. Combination'' consists of a combination of U.S. No. 1 and U.S. No. 2 strawberries, except

for size: Provided, That at least 80 percent, by count, of the strawberries meet the requirements

of U.S. No. 1 grade. 

(a) Size. Unless otherwise specified, the minimum diameter of each strawberry is not less than
2

three-fourths inch. 

(b) Tolerances. In order to allow for variations incident to proper grading and handling the

following tolerances, by count, are provided as specified: 

(1) For defects. Not more than 10 percent for strawberries in any lot which are seriously

damaged, including therein not more than one-fifth of this tolerance, or 2 percent, for

strawberries affected by decay. No part of any tolerance shall be allowed to reduce for the lot as

a whole, the percentage of U.S. No. 1 strawberries required in the combination, and individual

containers (cups or baskets) may have not less than 65 percent U.S. No. 1 strawberries:

Provided, That the entire lot averages within the required percentage. 

(2) For off-size. Not more than 5 percent of the strawberries in any lot may be below the

specified minimum size. 

§51.3117 U.S. No. 2. 

"U.S. No. 2'' consists of strawberries which are free from decay and free from serious damage

caused by dirt, disease, insects, mechanical or other means. Each strawberry has not less than

one-half of its surface showing a pink or red color. 

(a) Size. Unless otherwise specified, the minimum diameter of each strawberry is not less than

five-eighths inch. 

(b) Tolerances. In order to allow for variations incident to proper grading and handling the

following tolerances, by count, are provided as specified: 

(1) For defects. Not more than 10 percent for strawberries in any lot which are seriously

damaged, including therein not more than three-tenths of this tolerance, or 3 percent, for

strawberries affected by decay. 

(2) For off-size. Not more than 5 percent for strawberries in any lot which are below the

specified minimum size. 

§51.3118 [Reserved].

Application of Tolerances 

§51.3119 Application of tolerances. 

(a) The contents of individual packages (cups or baskets) in the lot, based on sample inspection,

are subject to the following limitations: 

(1) For a tolerance of 10 percent or more, individual packages (cups or baskets) in any lot shall

have not more than one and one-half times the tolerance specified, except that when the package

contains 25 specimens or less, individual packages shall have not more than double the tolerance

specified: Provided, That the averages for the entire lot are within the tolerance specified for the

grade. 

(2) For a tolerance of less than 10 percent, individual packages (cups or baskets) in any lot shall

have not more than double the tolerance specified, except that at least one defective and one

off-size specimen may be permitted in any package: Provided, That the averages for the entire

lot are within the tolerances specified for the grade. 

Definitions 

§51.3120 Overripe. 

"Overripe" means dead ripe, becoming soft, a condition unfit for shipment and necessitating

immediate consumption. 

§51.3121 Undeveloped. 

"Undeveloped" means that the berry has not attained a normal shape and development due to
