What aspect varies for milk classified according to use under Federal Orders?

Prices vary for milk classified according to use under Federal Orders because different uses of milk have different market demands and associated costs. For instance, milk intended for fluid consumption generally commands a higher price compared to milk used for cheese or butter production. This pricing structure is implemented to ensure fairness and stability in the dairy market, allowing producers to receive compensation that reflects the value of their product based on its intended use.

In contrast, packaging, transportation methods, and quality standards tend to be more uniform across various milk utilizations within the industry. These aspects are typically regulated by broader legislation and standards that apply across the board, regardless of how the milk will ultimately be used.
