What grading system is typically used to classify peanuts for commercial sale?

The grading system typically used to classify peanuts for commercial sale is based on a scale of U.S. No. 1 to U.S. No. 4. This system is established to ensure consistency and quality in peanut sales and to provide a clear understanding of the quality of the peanuts being sold.

U.S. No. 1 peanuts are considered the highest quality, featuring characteristics such as being well-formed, clean, and free from defects. As the grades decrease to U.S. No. 4, the standards for size, shell integrity, and overall appearance become less stringent. This classification allows buyers and sellers to communicate effectively regarding the quality of peanuts, ensuring that consumers receive peanuts that meet their expectations.

The other grading options mentioned do not conform to the recognized standards for peanut classification. The U.S. grading system is integral to the marketing of agricultural products, providing a basis for quality assurance that is essential in the commercial sale of peanuts.
