Pet food Co-Manufacturer Checklist for Brand Owners
Choosing a pet food co-manufacturer is one of the highest-impact decisions for a new or growing brand. The right manufacturing partner can turn a well-positioned concept into a consistent, compliant and scalable product. The wrong partner can create formulation compromises, delayed launches, supply issues, label errors or avoidable commercial risk.
This pet food co-manufacturer checklist helps brand owners evaluate potential production partners in a structured way. It covers product fit, technical expertise, quality assurance, regulatory readiness, capacity, commercial terms and operational reliability. Use it before shortlisting manufacturers, during factory assessments and before signing a manufacturing agreement.
What are FEDIAF and AAFCO?
FEDIAF is the European Pet Food Industry Federation. It publishes nutritional guidelines for complete and complementary pet food for cats and dogs, based on scientific evidence and expert input. Its guidelines are commonly used by manufacturers and technical teams as a reference when formulating products for the European market.
AAFCO, the Association of American Feed Control Officials, develops model regulations, ingredient definitions, labelling models and nutrient profiles for animal feed and pet food in the United States. AAFCO itself does not approve or certify individual pet food products. In practice, US feed control rules are adopted and enforced at state level, often with reference to AAFCO models and definitions.
FEDIAF vs AAFCO: the key differences
| Area | FEDIAF | AAFCO |
|---|---|---|
| Primary market relevance | European pet food market | United States pet food market |
| Main role | Nutritional guidelines and industry best practice | Model standards, nutrient profiles and feeding protocols |
| Regulatory context | Used alongside EU and national feed legislation | Used within state-level feed regulation in the US |
| Nutritional suitability | Guidance for complete and complementary feeds by species and life stage | Nutrient profiles and substantiation routes for life-stage claims |
| Common label language | Complete feed, complementary feed and mandatory EU label information | Nutrition adequacy statements, such as complete and balanced for a stated life stage |
| Product certification | Does not certify individual products | Does not approve individual products |
The two systems have similar objectives: helping manufacturers develop safe and nutritionally appropriate pet food. However, they should not be treated as interchangeable. A recipe designed for AAFCO compliance may still require reformulation, analytical review and label adaptation before launch in Europe. The same applies when an EU-developed FEDIAF-aligned formula is prepared for the US market.
How nutritional standards are used in pet food formulation
Both FEDIAF and AAFCO define nutritional expectations for different species and life stages. These requirements cover essential nutrients such as protein, amino acids, fat, fatty acids, vitamins, minerals and trace elements. They also account for factors including energy density, moisture content and the intended use of the product.
For a complete pet food, meeting nutrient targets involves more than selecting appropriate ingredients. The final formulation must be assessed on the correct basis, such as dry matter or energy basis, and should take nutrient variability, processing losses and ingredient bioavailability into account. The nutritional value of a formulation on paper is not always identical to the nutritional value of the finished product after manufacturing.
Life-stage suitability
AAFCO nutrient profiles commonly distinguish between adult maintenance and growth and reproduction. FEDIAF also provides nutritional guidance for relevant physiological stages, including growth, adult maintenance and reproduction. The exact nutrient values, definitions and application principles can differ between the frameworks.
For this reason, a brand should define the intended life stage early in product development. A recipe positioned for adult maintenance cannot automatically be marketed as suitable for growth, pregnancy or lactation without appropriate nutritional substantiation.
Complete versus complementary pet food
In the EU, a complete feed is designed to provide the daily ration when fed as directed. A complementary feed is intended to be fed alongside other products and should not be presented as the sole source of nutrition unless its use has been appropriately balanced within the total diet.
A similar principle applies to US products. A product described as “complete and balanced” must be nutritionally adequate for the specified life stage according to an appropriate substantiation route. Treats, toppers, supplements and many snack products are not intended to function as a pet’s sole diet.
AAFCO nutrient profiles and feeding trials
AAFCO nutritional adequacy can generally be supported in two ways. A product may be formulated to meet the relevant AAFCO nutrient profile, based on formulation work and nutritional analysis. Alternatively, it may be substantiated through feeding trials conducted according to AAFCO protocols.
- Formulated to meet nutrient profiles: the recipe is designed and assessed to meet the required nutrient levels for its stated life stage.
- Animal feeding trials: the product is evaluated through a controlled feeding study designed to assess its ability to support pets during the trial period.
Feeding trials can provide useful evidence of practical acceptance and nutritional performance, but they do not replace sound formulation, ingredient control, manufacturing quality assurance or post-production testing. Likewise, a profile-based formulation can be suitable when it is built on robust technical data and properly verified.
FEDIAF compliance in the European market
FEDIAF guidelines are important technical references for European pet food development, but they operate within a wider legal framework. Pet food placed on the EU market must also comply with applicable feed legislation, hygiene requirements, ingredient rules, additives legislation, animal by-product rules and country-specific requirements where relevant.
For European product launches, compliance work should therefore include more than checking a nutrient table. Brands need to review the formula, ingredient specifications, analytical plan, feeding instructions, mandatory declarations, claims and language requirements for each target market.
FEDIAF alignment can support a strong nutritional foundation, but it is not a substitute for a complete regulatory and technical review. Equally important is understanding pet food regulations.
What pet food labels can and cannot tell you
Labels can help buyers understand whether a product is intended as a complete daily food, a complementary product or a specialist item. However, label claims should always be interpreted in context.
- “Complete feed”: intended to provide the daily diet when fed according to instructions.
- “Complementary feed”: intended to be fed with other foods, not as the only source of nutrition.
- “Complete and balanced”: a US-oriented nutritional adequacy statement linked to a stated life stage.
- “Formulated to meet AAFCO nutrient profiles”: indicates profile-based nutritional substantiation rather than a feeding trial statement.
These statements do not automatically indicate ingredient quality, digestibility, palatability, suitability for a medical condition or superiority over another product. They primarily relate to nutritional adequacy within the stated scope.
Which standard should a pet food brand follow?
The appropriate framework depends primarily on the intended market. Brands selling in Europe should develop products in line with European legal requirements and use FEDIAF nutritional guidance where relevant. Brands entering the United States should consider AAFCO nutrient profiles, labelling expectations and the requirements of the states in which the product will be distributed.
For international launches, the most efficient approach is usually to define the target markets before finalising the recipe. This helps avoid late-stage changes to nutrient levels, additives, analytical specifications, claims or packaging artwork.

Practical considerations for international pet food development
A successful formulation needs to work commercially and technically across the intended markets. Before launch, pet food businesses should assess:
- Target species, life stage and product category
- FEDIAF and/or AAFCO nutritional benchmarks
- Ingredient legality and supplier documentation
- Manufacturing process and expected nutrient losses
- Analytical, microbiological and shelf-life testing requirements
- Substantiation for nutritional, functional and marketing claims
- Labelling, mandatory declarations and language requirements
- Export documentation and market-specific registration obligations

Frequently asked questions
Is FEDIAF the European equivalent of AAFCO
They are often compared because both provide nutritional guidance for pet food, but they are not identical organisations and do not operate in the same legal environment. FEDIAF is a European pet food industry federation publishing nutritional guidelines, while AAFCO develops model standards used in the US feed regulatory system.
Is AAFCO approval required for pet food?
AAFCO does not approve individual pet food products. In the US, pet food oversight is generally handled by state feed control authorities. Products may need to meet state-specific requirements that refer to AAFCO definitions, nutrient profiles and label models.
Does FEDIAF approve pet food products?
No. FEDIAF does not certify individual pet food products. Its nutritional guidelines are used as a technical reference, alongside the legal requirements that apply in the relevant European market.
Can one formulation meet both FEDIAF and AAFCO standards?
In some cases, a formulation may be developed to meet both frameworks. However, this should be assessed nutrient by nutrient and in relation to the intended life stage, product type, manufacturing process, labelling and target markets. Dual-market compliance should never be assumed without technical verification.
Is a product that meets AAFCO or FEDIAF standards automatically high quality?
Meeting relevant nutritional standards is an important baseline, but it does not alone determine overall product quality. Ingredient sourcing, manufacturing controls, digestibility, safety testing, shelf life, labelling accuracy and suitability for the intended pet population also matter.
