A '''Class II substance''' is a [[chemical]] assigned an [[ozone-depletion potential]] (ODP) of less than 0.2 by the [[Environmental Protection Agency]].

Currently, all of the [[hydrochlorofluorocarbon]]s (HFCFs) are class II substances. Lists of class II substances with their ODPs, [[global warming potential]]s, and [[CAS number]]s are available [http://www.epa.gov/ozone/ods2.html here].
