Substances used in food-contact articles (e.g., food-packaging or food-processing equipment) that migrate, or that may be expected to migrate, into food at negligible levels may be reviewed under  § 170.39 of this chapter.  The Food and Drug Administration will exempt substances whose uses it determines meet the criteria in  § 170.39 of this chapter from regulation as food additives and, therefore, a food additive petition will not be required for the exempted use.
