AAFCO labeling 99 lifecycle

AAFCO's named-ingredient rules (2024 Model Regulation PF3(c)) — commonly called the "95% rule" — state that an ingredient or combination of ingredients may form part of a brand or product name when the named ingredient(s) constitute at least 95% of the total weight of the product; water sufficient for processing may be excluded when calculating the percentage, but the named ingredients must still constitute at least 70% of the total product weight. So a product named "Chicken Dog Food" must be overwhelmingly chicken. Products that do not meet the 95% threshold fall to the next tiers: the 25% rule (PF3(c)(2)) requires at least 25% of the named ingredient (and at least 10% of total product weight) together with a descriptor such as "dinner", "platter", "entree", "formula" or "recipe" in the same size, style and color print; the "with" rule (PF3(d)) requires at least 3% of each named ingredient (e.g., "Dog Food with Chicken"), with type-size limits by panel size; and a flavor designation (PF3(e)) requires only that the flavor conform to a listed ingredient or identified source, with the word "flavor" printed as conspicuously as the flavor name and substantiation available on request. PF3(b) separately forbids "100%" or "All" names for multi-ingredient products.
