How to Check Whether a Manufacturer Really Makes What It Says It Does

Ask the question without assuming the answer

A supplier may be an excellent trading business that manages production elsewhere. The problem is a mismatch between the model you think you are buying and the actual route. Ask what is made at the named site, which processes are subcontracted, who controls quality and which legal entity will take the order.

Request the factory address and a description of the relevant production line or process. A company that answers with a catalogue but no explanation of production has not yet established that it makes your product.

Look for evidence that relates to your item

Product photographs, factory videos and certifications can be useful clues. Check whether they show the process you need, the claimed site and the current business. Ask for a live conversation with someone who understands production, a walk-through or visit when proportionate, and a sample or pilot that demonstrates the claimed capability.

A certificate needs scrutiny: issuer, validity, site, entity, scope and whether it covers the relevant activity. A certificate for a quality management system is not automatically a product approval. References can help when the supplier has permission to share them and you can speak to the customer directly.

Check the paper trail

Compare company names and addresses across quotations, invoices, certificates, registration records and payment instructions. For UK entities, Companies House offers public company records. Those records can establish registered details and filings, but they do not verify that a factory can manufacture a product.

For overseas entities, use the relevant local registers and independent professional checks where the risk warrants them. Do not infer a conclusion from one missing web result; ask for an explanation and evidence.

Decide what level of proof you need

A modest trial order and a safety-critical long-term contract do not call for the same depth of review. Scale the checks to the product, value, consequence of failure and available evidence. Keep an explicit list of unverified claims so they do not quietly become ‘facts’ in the final decision.
