This document clarifies a previous statement by EPA about the applicability of a Clean Air Act labeling rule to methyl bromide as a ``class I ozone-depleting substance.'' The labeling rule requires products ``containing'' or ``manufactured with'' a class I ozone- depleting substance to be labeled as such. This document makes clear that any product, including any agricultural product, that ``contains'' or is ``manufactured with'' methyl bromide is subject to the labeling rule's requirements. At the same time, EPA is not aware of any agricultural product that ``contains'' or is ``manufactured with'' methyl bromide, as those terms are defined by the labeling rule. In particular, raw food commodities grown for the fresh food market and produced with the use of methyl bromide do not meet the definitions of products ``containing'' or ``manufactured with'' methyl bromide and are thus not subject to the labeling rule's requirements.
