Grain grading
A system of classifying grain based on specific physical and chemical quality standards that determine its final commercial value and suitability for processing.

Grain grading involves testing samples for moisture, test weight, protein content, and foreign matter. These metrics enable producers and buyers to categorize grain into specific grades, determining whether it meets standards for human consumption, livestock feed, or industrial processing.
For grain traders and farmers, accurate grading is the primary factor in determining market value. Inconsistent grading can lead to significant price discounts or rejection of shipments at storage facilities, directly affecting the profit margins of the harvest.
A common error is the lack of representative sampling, which leads to inaccurate quality assessments of the entire lot. Additionally, improper storage management, such as failing to maintain stable moisture levels, frequently results in grain degrading in quality, causing a shift to a lower commercial grade.
