The transportation of food completely enclosed by its container that does not require temperature control for safety is not subject to the ST rule per the exclusion in the definition of “ Transportation operations”. Under the rule, a completely enclosed container is one that physically separates the food from the environment and functionally protects it from environmental contamination during transportation. Please see Comment/Response # 59 and Comment/Response #60 in the ST rule for information about the meaning/examples of completely enclosed by a container. For example, a container can be a tote, a cardboard box, a plastic bag/box, a metal can, a glass/plastic bottle, or a bin. If you transport only food that is completely enclosed and does not require temperature control for safety, you are not subject to the ST rule.
