How to Check Feed Supplier Documents Before You Place an Order

Short answer Before ordering, match the supplier’s legal identity to official records, define the product specification, and assess whether its certificate of analysis supports the offered batch. Check certificate claims against the issuing body’s public register, confirm applicable import documents, and connect samples and contract terms to identifiable lots. Resolve inconsistencies in writing before committing funds. Knowing how to verify feed supplier claims means checking what each document proves—and what it does not. Use the seven numbered steps below as your pre-order review.

1. Who is the legal entity behind the offer? Request the registered company name, registration number, registered address, contracting entity and beneficiary bank details. Search the relevant official company register where accessible; retain the record and review date. A registration establishes legal existence, not product quality or financial strength. Compare names across the quotation, invoice, registration and bank instructions. If the seller is a trader, identify the manufacturer and explain each party’s role. Different entities are not automatically unacceptable, but their relationship needs evidence. ### Escalate identity mismatches Ask for a written explanation of unexplained name or address differences. Independently confirm unusual payment instructions through an established contact channel, not a number supplied only in the change request. Include applicable sanctions and restricted-party checks in your wider approval process.

2. What must the product data sheet specify? Obtain a dated, version-controlled product data sheet and a proposed contractual specification. A marketing sheet may describe typical composition without setting enforceable acceptance limits. Record the ingredient identity, processing method, intended feed use, physical form, packaging and storage conditions. Define relevant nutritional parameters, moisture, contaminants and other safety criteria for the ingredient and destination. State units, reporting basis, test methods and whether each figure is a minimum, maximum or typical value. For supplier due diligence, feed buyers should involve their nutritionist and quality team before accepting substitutions or broad tolerances. Confirm that the offered grade—not another product in the same range—is covered. A complete file is still unsuitable if it describes the wrong material.

3. Does the COA demonstrate compliance with the specification? A certificate of analysis, or COA, reports results for a sample; a specification defines requirements. Request the lot number, sampling and testing dates, methods, units, reporting basis and laboratory identity. Establish whether the COA concerns available stock, a previous shipment or a representative sample. | Evidence | What it supports | What it does not establish | |---|---|---| | Product specification | Agreed acceptance limits | Actual batch performance | | Batch-linked COA | Results for the tested sample | Uniformity throughout a shipment | | Historical COA | Prior analytical profile | Compliance of future supply | ### Compare on the same basis > **Illustrative example only:** Dry-matter protein (%) = as-received protein (%) ÷ [1 − moisture (%) ÷ 100]. At 44% protein and 12% moisture, the result is 50% dry-matter protein. These hypothetical inputs are not expected product results. Conversion cannot correct unrepresentative sampling or incompatible methods. See [COA and dry-matter quote comparison](/blog/compare-feed-ingredient-quotes-coa-dry-matter) before treating differently reported values as equivalent.

4. How do you check certificate claims independently? To check supplier certificate claims, record the scheme, certificate number, legal entity, site, scope, issuer and validity dates. Locate the issuing body’s public register independently rather than relying solely on an emailed link or QR code. Match the register entry to the actual production or handling site and relevant activity. A certificate for warehousing does not automatically cover manufacturing; a group name does not automatically cover every subsidiary. Check current status and any listed restrictions. If no public entry is available, ask the issuer through independently sourced contact details. Treat missing information as unresolved, not immediate proof of fraud. Verify accreditation separately where claimed and relevant. Certification within a defined scope does not replace lot-specific analysis or destination-country compliance.

5. Which origin and import documents are required? Separate country of manufacture or production from country of dispatch. Request the proposed origin declaration and traceability chain, then establish which official documents the destination requires for this ingredient, processing status and intended use. Depending on the trade lane and product, requirements may include a certificate of origin, phytosanitary certificate, veterinary or health certificate, import permit or other declarations. Do not assume every feed ingredient needs the same documents. Confirm requirements with the competent authority or a suitably qualified customs specialist. Before ordering, agree who obtains each document and provides draft wording. Some shipment documents cannot exist until dispatch: make their delivery and acceptance explicit contractual conditions, then reconcile quantities, lot identifiers and consignee details when issued.

6. Can the sample be traced to the offered material? Assign every evaluation sample an identifier. Record its source, lot, collection date, sampler, sampling method, seal numbers and storage conditions. Ask whether it was drawn from saleable stock, a production trial or a retained reference sample. A favourable result from an unidentified sample provides weak evidence about a future shipment. For material risks, agree a representative sampling protocol, suitable independent testing and retention of sealed duplicate samples. Specify the laboratory, methods and how conflicting results will be resolved. If the purchase concerns future production, distinguish sample approval from shipment release. State whether the approved sample is a descriptive reference or a contractual benchmark; neither should silently override the written specification.

7. How should the contract reference the reviewed documents? Create a document schedule with exact titles, dates, versions and relevant lot numbers. Incorporate the agreed specification expressly and define which document prevails if the quotation, data sheet and contract conflict. Have a lawyer review enforceability and remedies where needed. ### Pre-order release checklist - Contracting entity and payment beneficiary are reconciled. - Product grade, limits, methods and reporting basis are agreed. - COA status and batch linkage are understood. - Certificate scope and public-record checks are recorded. - Required origin and import documents have named owners. - Sampling, inspection and shipment-release conditions are defined. - Rejection, retesting, claims deadlines and dispute procedures are agreed. Mark unresolved items as conditions requiring approval, not assumptions buried in email. Keep a dated review log and the evidence supporting each decision.

What common mistakes weaken document review? Common mistakes include accepting a company registration as quality assurance, treating typical values as guarantees, and assuming an authentic certificate covers the offered site or product. Another is approving a historical COA as though it belongs to the shipment. Avoid judging documents by appearance alone: polished PDFs can be incomplete, while genuine records may use unfamiliar formats. Translate material terms where necessary and preserve originals. Do not let a commercially attractive quotation bypass unresolved identity, safety or import issues. Document review reduces information gaps; it cannot guarantee supplier conduct or shipment quality.

What should you do next with the document pack? Build a discrepancy register with an owner, requested evidence and release condition for each open point. Compare only commercially comparable offers through the [procurement workflow](/procurement) and [supplier comparison calculator](/feed-tco-supplier-comparison-calculator). Tools and calculators provide preliminary planning outputs; they do not replace a nutritionist, engineer, laboratory, lawyer, financial adviser or other relevant specialist. For commercial opportunities of USD 250,000 or more, submit requirements and available documents through [RFQ intake](/rfq-intake). FeedMatch’s workflow is human-led and supplier-neutral, with human review before any supplier contact. Submitted documents and relevant public records can be reviewed. FeedMatch is not a certification body and does not audit factories; the buyer retains supplier-selection and approval responsibility.
