     (a) When the calcium, salt, and sodium guarantees are given in the guaranteed analysis, they must be stated and conform to the following:

     (i) When the minimum is below 2.5%, the maximum must not exceed the minimum by more than 0.5 percentage points.

     (ii) When the minimum is 2.5% but less than 5.0%, the maximum must not exceed the minimum by more than one percentage point.

     (iii) When the minimum is 5.0% or greater, the maximum must not exceed the minimum by more than 20% of the minimum and in no case may the maximum exceed the minimum by more than five percentage points.

     (b) When stated, certain mineral guarantees must be expressed as follows:


Sodium, Salt, Potassium, Magnesium, Sulfur, Phosphorus, Fluorine, Other
Mineral Guarantee: Expresses As:
Minimum and maximum total sodium Percentage (%)
Minimum and maximum salt Percentage (%)
Minimum potassium Percentage (%)
Minimum magnesium Percentage (%)
Minimum sulfur Percentage (%)
Minimum phosphorus Percentage (%)
Maximum fluorine Percentage (%)
Other minimum mineral guarantees Parts per million (ppm) when the concentration is less than 10,000 ppm
Other minimum mineral guarantees Percentage when the concentration is 10,000 ppm (1%) or greater

     (c) Minerals, except salt, when quantitatively guaranteed, must be stated in terms of percentage of the element.

     (d) Products labeled with a quantity statement (for example, tablets, capsules, granules, or liquid) may state mineral guarantees in milligrams (mg) per unit (for example, milligrams per tablet or milligrams per capsule) consistent with the quantity statement and the directions for use.

     (2) All mineral phosphatic materials used for feeding purposes must be labeled with the guarantee for:

     (a) Minimum and maximum percentage of calcium (when present);

     (b) Minimum percentage of phosphorus; and
