The agency may grant the exemption, under such conditions as it may prescribe by regulation, if the agency finds that the State requirement will not cause any food to be in violation of any applicable requirement under Federal law, will not unduly burden interstate commerce, and is designed to address a particular need for information that is not met by the preemptive Federal requirement.

Slack-fill is the difference between the actual capacity of a container and the volume of product contained therein. Nonfunctional slack-fill is the empty space in a package that is filled to less than its capacity for reasons other than: (1) Protection of the contents of the package; (2) The requirements of the machines used for enclosing the contents in such package; (3) Unavoidable product settling during shipping and handling; (4) The need for the package to perform a specific function (e.g., where packaging plays a role in the preparation or consumption of a food), where such function is inherent to the nature of the food and is clearly communicated to consumers; (5) The fact that the product consists of a food packaged in a reusable container where the container is part of the presentation of the food and has value which is both significant in…
