Evaluating a Food Manufacturer: Questions, Samples and Certifications

Choosing a manufacturer is one of the biggest decisions a food brand makes. Take your time and ask detailed questions.

Start with your own specification

Write a clear brief: the product, recipe or target specification, expected volumes, packaging, shelf life, labelling needs and your target cost. A clear brief makes quotes comparable and shows you are serious.

Ask about their experience and capacity

What products do they make now? Have they made similar items, such as seed blends or powders? What is their minimum order quantity, their lead time and their capacity to grow with you? Can you visit the facility, in person or by video? A good manufacturer should be happy to show you around, and to provide references from other clients.

Ask about quality and safety systems

Ask how they control quality from incoming ingredients to finished product. Do they test batches? How do they handle traceability and recalls? What is their cleaning and pest control routine? Ask about staff training and how they manage allergens, especially if they process nuts, sesame or other seeds on shared lines. Ask what they do to prevent cross-contact, and whether they can provide allergen statements and cleaning verification.

Check certifications

Certifications show that a facility has been audited against a standard. Common examples include recognised food safety schemes, and for specific claims, organic, kosher, halal or gluten-free certification. Ask to see current certificates, check the expiry dates and confirm the scope covers the products you want. Where possible, verify with the certifying body. Requirements for selling food differ by country, so confirm what applies in your market.

Request pre-production samples and compare them with your specification. Taste them, check texture, colour and packaging, and have them tested if you need nutritional or microbiological data. Ask for a trial batch before committing to a full run, and check that the batches are consistent.

Review costs and terms

Compare quotes line by line: ingredients, processing, packaging, labelling, storage, shipping, testing and any set-up charges. Ask who owns the recipe and who buys ingredients. Put agreements in writing, including quality standards, confidentiality, ownership of formulas and what happens if a batch fails. Consider getting a lawyer to review contracts.

Watch for warning signs

Be cautious if a manufacturer will not share documents, avoids questions about allergens, cannot show certificates or pushes you to sign quickly. Trust your instincts and talk with at least two or three options before choosing.

After you start, continue to check batches, audit periodically and keep open communication. A good manufacturer becomes a long-term partner.

Keep a checklist of your questions and score each candidate the same way, so you compare like with like rather than relying on a good sales pitch. Share the shortlist with a trusted adviser, such as a food technologist, before you decide.
