The short answer
Check company identity, production scope, sample quality and project-specific evidence. A brochure or certificate image alone does not confirm that a supplier can meet your specification.
Use several forms of evidence together. The goal is to establish who will make the bottle, who controls decoration and closures, and who is responsible if the delivered pack differs from the approval.
Map the production responsibilities
Ask which stages are performed directly and which use partners. Request a clear point of contact for drawings, inspection and delivery. Confirm the legal entity shown on quotations, invoices and agreed documents.
Check relevance rather than document quantity
Review certificate scope, issuing body, dates and the product or site covered. Ask for evidence relevant to the selected material, decoration and intended use. Do not assume one document applies to every bottle and destination.
Procurement checklist
- Match company names across commercial documents.
- Understand the manufacturing and decoration scope.
- Assess samples against your specification.
- Check the applicability of test documents.
- Agree responsibility for deviations and follow-up.
Common question
Can a certificate replace sample approval?
No. A document and a sample answer different questions. Review relevant documentation and verify the actual bottle, closure and decoration through a defined approval process.
