Which of the following is a legal requirement for honey labels?

The legal requirement for honey labels includes the net weight of the product. This is crucial because it ensures consumers are aware of the quantity they are purchasing, which helps in making informed buying decisions. The net weight must be displayed clearly on the label, allowing buyers to compare the value of different honey products effectively.

Other aspects like the product's expiration date, color of the honey, or terroir information, while potentially beneficial for marketing or consumer education, are not mandated by labeling laws for honey. Therefore, focusing on net weight as a legal necessity emphasizes the importance of transparency and consumer rights in the food industry.
