(a)  The sliding scale method of expressing a guaranteed analysis (for example, "protein 15‑18 percent") is prohibited.

(b)  Pet foods containing five percent or more mineral ingredients, shall include in the guaranteed analysis the minimum and maximum percentage of calcium (Ca) and salt (NaCl), and the minimum percentages of phosphorus (P) and iodine (I), if added.  Minerals, except salt (NaCl), when quantitatively guaranteed shall be stated in terms of percentage of the element.  The label of the pet food which is formulated as and represented to be a mineral supplement shall include a guarantee of all the minerals contained in the ingredient statement.

(c)  The label of the pet food which is formulated as and represented to be a vitamin supplement, shall include a guarantee of the minimum content of each vitamin declared in the ingredient statement.  Such vitamin guarantees shall be stated in units or milligrams per pound or ppm, as provided herein; vitamin E in USP or International Units; vitamin A, other than precursors of vitamin A, in USP Units; vitamin D in USP units: all other vitamins as true vitamins, not compounds, except pyridoxine hydrochloride, choline chloride, and thiamine; oils and concentrates containing vitamin A or vitamin D or both may be additionally labeled to show vitamin content in units per gram; and providing that the term "d‑pantothenic acid" be used in stating the pantothenic acid guarantee.
