What does a food buyer check before approving a new ingredient supplier?
They check which food-safety scheme certifies your plant, whether you can produce a product specification and a certificate of analysis, and how allergens are handled. Naming the scheme — and its certificate number — is the difference between a supplier who can be audited and one who cannot.
A technical manager at a food manufacturer is deciding whether your plant can be added to an approved supplier list without a site visit.

Scope and specifications
- Product and form
- Powder, paste, concentrate and whole change the application entirely.
- Specification summary
- Composition, moisture, particle size and microbiological limits.
- Shelf life and storage conditions
- Determines whether it fits the buyer's supply chain.
- Packaging and pack sizes
- Drives handling, cost and minimum order.
- Origin
- Increasingly a buying criterion in its own right, not just a label.
- Private label capability
- A different business from ingredient supply, and buyers search for it separately.
- HS code
- Needed before the buyer's import team can cost the purchase.

| Product specification sheetAsked at: first technical evaluation | Composition, microbiological limits, shelf life and storage | Publish it |
| GFSI-recognised certificate (FSSC 22000, BRCGS, SQF or IFS)Asked at: supplier approval — usually a gate, not a preference | That the plant is certified under a scheme the buyer's own customers accept | Publish it |
| Certificate of Analysis (CoA)Asked at: with every batch | Batch conformance to specification | Per shipment |
| Allergen statementAsked at: before any sample enters the buyer's plant | Which allergens are present, and what shares the line | Publish it |
| FSSAI licence or destination-market registrationAsked at: onboarding | Legal manufacturing and export status | Publish it |
| Halal, kosher or organic certificatesAsked at: where the destination market demands it | Market-specific requirements, with the certifying body named | Publish it |
| Traceability and recall procedureAsked at: audit and approval | That a batch can be traced forward and back within a stated time | Name it, share on request |

- Drives price and feasibility.
- Destination market
- Determines certification and labelling requirements.
- Certification required
- Halal, kosher, organic and GFSI scheme are hard filters.

- Sample logistics for food are their own process.
- Required date
- Seasonality and crop cycles matter more here than in most industries.
Questions suppliers ask
Which food safety certification should we lead with?
Lead with the GFSI-recognised scheme your plant actually holds — FSSC 22000, BRCGS, SQF or IFS — and publish the certificate number and issuing body beside it. Buyers whose own customers demand a specific scheme are filtering on that word, so the scheme name matters more than the phrase "certified".
Should specifications be public or behind a form?
Publish enough of the specification for a technical buyer to judge fit: form, key parameters, shelf life, pack size and allergens. Full specification documents and pricing can reasonably sit behind contact. The public version exists so that the buyer knows whether contacting you is worth it.
We supply commodity products. Does any of this apply?
More so, because when the product is comparable the supplier becomes the differentiator. Origin, certification, consistency evidence and documentation speed are what a commodity buyer actually chooses between, and they are all publishable.
