What is the defect tolerance for onions, which are scored by weight?

The defect tolerance for onions that are scored by weight is indeed 5% single/combo. This standard reflects the industry norms for grading and evaluating onions, specifically how many defects are allowable in the graded commodity.

In the context of onion grading, "defect tolerance" is important because it provides growers, packers, and buyers with clear guidelines on the quality expected for marketable onions. A 5% tolerance indicates that up to 5% of the total weight may consist of defects, whether they are considered single or in combination with other defects.

This tolerance helps in ensuring that the product meets acceptable quality standards while considering factors like natural variations in produce, handling, and shipping conditions that may cause some level of defect. This standard is practical as it balances quality control with the realities of agricultural production and handling.

Standards for defect tolerance can vary for different commodities, and it’s important to be familiar with specific regulations for each type of produce, making the knowledge of the 5% tolerance for onions essential for anyone working within the field of commodity regulation.
