BSCI audit and ISO 9001 certification: what each one tells you — and what neither does
Factory websites put these two logos side by side, and buyers often read them as one general stamp of approval. They answer two different questions, and leave a third one unanswered.
BSCI: an audit of how a factory treats its workers
BSCI is a social compliance audit. An independent auditor visits the factory and checks working conditions — working hours, wages, health and safety, and the other areas in the code of conduct.
The correct word is audited, not certified. The outcome is an audit report for a specific site and date, not a certificate that stays valid indefinitely. When you evaluate a supplier, ask for the current audit report and check that it is still valid, rather than relying on a logo on a website.
ISO 9001: a certificate for a quality management system
ISO 9001 certifies that a factory runs a documented quality management system: defined processes, records, corrective actions and management review. It is about how the factory controls its work, not about any one product.
Every ISO 9001 certificate has a scope, printed on the certificate, stating which activities it covers. That scope is the part to read. Ours covers the production of plastic cups; it does not extend to every plastic container or to stainless steel products, and we do not describe it that way.
What neither of them proves
Neither BSCI nor ISO 9001 shows that a particular lunch box, cup or bottle is safe for food contact. A factory can be audited and certified and still make a product from the wrong grade of resin.
Food-contact compliance is shown separately: by test reports on the product and material for the market you sell into, and, for the factory in China, by its food-contact production licence. For which tests each market expects, see our food-contact compliance article.
A short table to keep on file
| Question | Document | What to check |
|---|---|---|
| Does the factory treat workers properly? | BSCI audit report | Site name and address, audit date, current validity |
| Does the factory control its quality processes? | ISO 9001 certificate | Certification body, scope wording, expiry date |
| Is this product safe for food contact in my market? | Product test reports; factory production licence | Product and material tested, standard used, report date |
What to ask a supplier
- Send the current BSCI audit report, not only the logo.
- Send the ISO 9001 certificate so the scope can be read.
- Which food-contact test reports exist for this model and this material?
- Is the site on the documents the site that will make my order?
Every one of these has a document behind it. A supplier who answers with documents is easier to buy from than one who answers with logos.
