Commercial bean class comes before comparison
USDA standards divide dry edible beans into named classes including pea or navy, blackeye, cranberry, pinto, Great Northern, several white and kidney classes, pink, black, mung, lima and chickpea, plus miscellaneous and mixed beans. USDA ERS notes that the catchall dry-bean category contains dozens of classes and that many operate as separate markets. Atlas therefore keeps class and variety where material attached to every production, grade, price and trade record; fresh snap beans, soybeans, canned beans and processed bean products remain separate.
