The US pet product market — worth over $130 billion annually — is regulated by a patchwork of federal and state authorities that catches many international brands off guard. Pet food is regulated by the FDA's Center for Veterinary Medicine (CVM) and by state feed control officials applying AAFCO (Association of American Feed Control Officials) model regulations. Pet accessories, toys, and non-food products face CPSC and FCC oversight similar to consumer goods. Getting the right regulatory pathway before your first US shipment is essential.
The FDA's Center for Veterinary Medicine regulates all animal food and drugs under the FD&C Act. For pet food, this means: all ingredients must be either GRAS (Generally Recognized as Safe) for the intended species, approved food additives, or ingredients covered by an AAFCO definition. Novel ingredients not meeting these criteria require FDA approval via a new animal drug application or food additive petition before use in US pet food.
FDA CVM also enforces cGMP (current Good Manufacturing Practice) standards for pet food facilities under 21 CFR Part 507 (FSMA's preventive controls for animal food). Foreign facilities manufacturing pet food for US export must register with the FDA and comply with or be verified against these standards.
AAFCO (Association of American Feed Control Officials) is a private organization of state and federal feed control officials that develops model pet food regulations adopted by most US states. AAFCO establishes: (1) Ingredient definitions — the AAFCO Official Publication lists approved ingredients by name and definition. Ingredients not in the AAFCO publication require individual state approval before sale. (2) Nutritional adequacy standards — AAFCO profiles for 'complete and balanced' nutrition for dogs and cats. (3) Label format requirements.
Because AAFCO regulations are adopted at the state level, technically your product must be registered or licensed in each state where it is sold. Most brands register in all states via a common state registration process, typically costing $50–$500 per state per year.
AAFCO-compliant pet food labels must include: (1) Product name (with specific naming rules — e.g. a product named 'Chicken Dog Food' must be at least 95% chicken by weight). (2) Net weight. (3) Guaranteed Analysis (minimum crude protein, minimum crude fat, maximum crude fiber, maximum moisture). (4) Ingredient list in descending order of predominance by weight before processing. (5) Nutritional Adequacy Statement ('complete and balanced for [life stage]' based on AAFCO profiles or feeding trials). (6) Feeding directions. (7) Manufacturer/distributor name and address.
The product naming rules are uniquely complex: '25% rule' (if the name includes a single ingredient, that ingredient must be at least 25% by weight); 'flavor rule' (ingredients in the name without a percentage qualifier must be present in sufficient quantity to be detected).
Most US states require pet food products to be registered with the state department of agriculture before sale in that state. Registration requirements vary: some states require a formula submission, some require label review, some require feeding trial or nutritional analysis results. Fees are typically $50–$500 per product per state per year.
The registration process is managed separately in each state. Services like PetFoodReg or state-licensed regulatory consultants can manage multi-state registration on your behalf. California, New York, and Texas have the most stringent requirements and the largest market sizes — prioritize these first if doing a staged rollout.
Pet accessories (collars, leashes, beds, carriers) and pet toys are regulated as consumer products under CPSC jurisdiction — similar to human consumer goods. Key standards: lead content limits (particularly for metal components), phthalate restrictions for plastic toys, flammability requirements for pet beds, and CPSC's reporting obligations for defective products.
Pet toys specifically face increasing scrutiny from CPSC for choking hazard risks. While no mandatory ASTM standard exists yet for pet toys, brands should conduct safety testing and maintain records. California's Prop 65 applies to pet products — lead, cadmium, and other chemicals in leashes, collars, and toys can trigger warning requirements.
Pet food imported into the US requires FDA prior notice (submitted via PNSI or the Automated Broker Interface) and must come from an FDA-registered foreign facility. USDA APHIS oversight applies to pet food containing meat, poultry, or certain animal products — an import permit from APHIS may be required depending on the country of origin and ingredients involved.
Countries with animal disease restrictions (e.g. foot-and-mouth disease present) face additional APHIS import restrictions on products containing meat from those countries. Work with a US customs broker experienced in food and pet food imports to navigate the joint FDA/APHIS documentation requirements.
