How to Write a B2B Vegan and Allergen Declaration for Retail Buyers¶

If you are manufacturing cosmetics, food products, dietary supplements, or even textiles, your commercial success depends entirely on securing shelf space with major retailers and listings on online marketplaces.

However, before a supermarket chain, specialty boutique, or pharmacy distributor signs a purchasing agreement, their procurement and quality assurance teams will send you a detailed compliance packet. Near the top of their list will be a mandatory request for a Vegan Declaration and an Allergen Declaration.

With consumers increasingly demanding transparency regarding ingredients, and with strict food allergen labeling laws globally, retailers cannot afford the massive liability of a mislabeled product. If a consumer suffers a severe allergic reaction due to an undeclared ingredient, or if a vegan product is found to contain animal-derived gelatin or animal testing traces, the retailer faces a PR nightmare and potential class-action lawsuits.

To protect their business, buyers require you to legally certify your product's ingredient purity. Here is how to write a legally robust, audit-ready B2B vegan and allergen declaration.

1. What is a B2B Vegan Declaration?¶

Many brands believe that to declare a product "Vegan," they must pay thousands of euros to an external organization for a consumer-facing trademark logo (like the Vegan Society's V-Label).

While these consumer logos are excellent for marketing, they are not a B2B legal requirement. A B2B Vegan Declaration is a self-declaration document. By signing it, you are legally certifying to your retail buyers that your product and its entire manufacturing process meet strict vegan standards.

What Your Vegan Declaration Must Certify:¶

• No Animal Ingredients: The product contains no meat, fish, poultry, dairy, eggs, honey, or any animal-derived byproducts (such as gelatin, cochineal dye, or stearic acid derived from animal fat).
• No Animal Processing Aids: No animal-derived substances were used during the processing or filtration of the ingredients (e.g., using isinglass from fish bladders to clarify beer or juice).
• No Animal Testing: Neither the finished product nor any of its individual ingredients have been subjected to animal testing by your company, your raw material suppliers, or any third-party laboratory acting on your behalf.
• Cross-Contamination Controls: If the product is manufactured in a facility that also processes animal products, you must declare that strict cleaning and scheduling protocols are in place to prevent cross-contamination.

2. What is an Allergen Declaration?¶

An Allergen Declaration is a critical food and cosmetic safety document. It details whether any of the major globally recognized food or cosmetic allergens are present in your product as direct ingredients, or if there is a risk of cross-contact during manufacturing.

In the EU, UK, and US, food safety regulations mandate the clear disclosure of major allergens. In the US, under the Food Allergen Labeling and Consumer Protection Act (FALCPA) and the newer FASTER Act, you must declare the "Big 9" allergens: 1. Milk 2. Eggs 3. Fish 4. Crustacean Shellfish 5. Tree Nuts 6. Peanuts 7. Wheat 8. Soybeans 9. Sesame

In the EU, the list expands to 14 major allergens, including celery, mustard, lupin, and sulfur dioxide/sulfites (at concentrations of more than 10mg/kg).

For Cosmetics (The Fragrance Allergens)¶

If you make cosmetics or personal care products, your allergen declaration must focus on the EU's restricted fragrance allergens (which expanded significantly to 80+ substances). If any of these substances are present in your formula above 0.001% for leave-on products (like creams) or 0.01% for rinse-off products (like soaps), they must be declared on your product label and your B2B declaration.

3. How to Draft the Declarations (The Required Fields)¶

A legally robust B2B declaration must not be a vague, casual email. It should be structured as a formal corporate document containing:

• Header: Your company logo, legal entity name, and physical address.
• Product Traceability: Exact product names, brand names, and SKU or barcode numbers.
• Explicit Statements: Clear, unambiguous statements (e.g., "We hereby certify that the product listed below contains no ingredients of animal origin..." or "The product is free from the 14 major EU allergens...").
• Basis of the Claim: Explicitly state that the declaration is based on thorough raw material audits and written confirmations from your chemical and ingredient suppliers.
• Signature & Corporate Title: Signed by an authorized quality control manager, formulation chemist, or CEO. A signed PDF establishes legal accountability, which is exactly what the retailer’s legal team requires.

4. Automating Ingredient Compliance with Sustalium¶

Chasing dozens of global raw material suppliers for signed allergen and vegan questionnaires is a massive administrative headache for quality assurance teams.

Sustalium’s material safety and chemical compliance platform automates this entire process.

Instead of manual emails, Sustalium provides your ingredient suppliers with a secure, structured portal to upload their material disclosures and signed safety statements. Our platform consolidates this data at the product formulation level and instantly generates a professional, verified B2B Vegan or Allergen Declaration. You can share this via a secure link or QR code, giving retail buyers immediate, audit-ready proof of compliance.

Frequently Asked Questions¶

Is a self-declaration enough for retailers, or do I need a third-party certificate? For the vast majority of B2B procurement processes, a legally binding self-declaration signed by your authorized quality manager is fully sufficient. Third-party certifications (like Halal or Vegan trademarks) are primarily consumer-facing marketing tools for your packaging.

What is the difference between 'Free-From' and 'May Contain' in allergen declarations? A "Free-From" declaration means the allergen is entirely absent from the recipe and that strict manufacturing controls prevent any cross-contamination. A "May Contain" statement (precautionary allergen labeling) is used when the allergen is not an intentional ingredient, but is processed in the same facility and cross-contact cannot be completely ruled out.
