Exempt Infant Formulas Marketed in the United States By Manufacturer and Category

An exempt infant formula is an infant formula intended for commercial or charitable distribution that is represented and labeled for use by infants who have inborn errors of metabolism or low birth weight, or who otherwise have unusual medical or dietary problems (21 CFR 107.3). Prior to any company or person manufacturing and marketing a new exempt infant formula or any infant formula, certain practices, procedures and processes must be followed (Section 412 of the Federal Food, Drug, and Cosmetic Act). For exempt infant formulas, there are specific terms and conditions that must also be met (21 CFR 107.50). The following list provides all of the products classified as exempt infant formulas that FDA believes are currently available (to date) on the U.S. retail market. The products are grouped by the company that manufactures and/or distributes them as well as grouped by type of product (if applicable).

This list is provided as a service to anyone using FDA's website and does not represent FDA endorsement of these companies or their products. FDA cannot ensure that the information on this list is the most current. As the agency becomes aware of newer information, the list will be periodically updated.
