Duck egg classification:

Duck eggs will be classified into grade AA, grade A and grade B. The tolerance for each grade of duck eggs is as follows:

+ For grade A: grade B eggs can be mixed, but the number of grade B eggs is not greater than 15% of the total number of eggs.

All three quality grades mentioned above must not contain cracked, cracked, or crushed eggs; During transportation, one cracked, cracked, or crushed egg is allowed, but not greater than 3.4% of the total number of eggs.
