Pet food label requirements: the complete checklist

A U.S. pet food label is one of the most heavily specified labels a small maker will ever build. Federal rules set the core (FDA's 21 CFR Part 501 and the FPLA); the "complete and balanced," feeding, and calorie pieces come from model regulations that states adopt. Here is every required element, where it goes, and the rule behind it.

Who regulates pet food

Pet food is a "food" under the Federal Food, Drug, and Cosmetic Act, so the FDA has baseline authority over it. FDA's animal-food labeling rules live in 21 CFR Part 501, and the net-quantity rules come from the Fair Packaging and Labeling Act (15 U.S.C. 1451 et seq.). On top of that, most states regulate pet food under their own feed laws, which commonly adopt the AAFCO model regulations — that is where the nutritional-adequacy statement, feeding directions, and calorie statement come from. Because state adoption varies, always confirm your state's requirements.

The pet food label at a glance

1. Product identity and species designation

The principal display panel must identify what the product is and the species it is for — "Dog Food," "Cat Treats," and so on (21 CFR 501.4 / 501.18). Product-naming conventions limit how you may name a food after an ingredient (the well-known "95%," "25%/dinner," "with," and "flavor" rules), so the name has to match what is actually in the product.

2. Net quantity of contents

Declare the net weight on the front panel in both US customary and metric units, US customary first, in the bottom 30% of the panel (FPLA / 16 CFR 500).

3. Guaranteed Analysis

The Guaranteed Analysis declares, at minimum, crude protein (minimum), crude fat (minimum), crude fiber (maximum), and moisture (maximum), plus any additional guarantees you choose to make. These are your numbers, from your formulation or lab analysis. A formatter lays them out; it does not — and should not — calculate or verify them. How the Guaranteed Analysis works →

4. Ingredient list

List every ingredient by its common or usual name, in descending order of predominance by weight (21 CFR 501.4(a)). Collective terms generally cannot stand in for the actual ingredients.

5. Nutritional adequacy / feeding statement

A food sold as complete and balanced must carry a nutritional-adequacy statement naming the life stage and how it was substantiated (formulated to a nutrient profile, or feeding trials). A treat, mixer, or supplement instead carries an "intermittent or supplemental feeding only" statement. Which statement your product needs →

6. Feeding directions

A complete and balanced food must give feeding directions — at least how much to feed per unit of body weight, and how often.

7. Calorie content statement

Dog and cat foods, including treats, carry a calorie content statement in kilocalories of metabolizable energy (ME) per kilogram and per a familiar measure (per cup, per treat). Again, these are your figures.

8. Manufacturer or distributor identity

Give the name and place of business of the manufacturer, packer, or distributor, qualified ("Manufactured for" / "Distributed by") if you are not the manufacturer (21 CFR 501.4 / FPLA).

9. California Prop 65 (if you sell into California)

If you sell into California and the product can expose people to a listed chemical above its safe-harbor level, add the short-form Proposition 65 warning (27 CCR 25603).

Put it together

Front panel: product name, species designation, and net quantity. Information panel: the Guaranteed Analysis, ingredient list, nutritional-adequacy/feeding statement, feeding directions, calorie statement, and your business identity.
