Ask "what certifications should my manufacturer have" and the top results explain single standards without answering the question. Here is the practical answer, from a factory that gets audited: which certificates matter for which purpose, and — more important — how to check a claim is real.
The Certification Map
| Certification / audit | What it actually covers | Who needs it | How to verify |
|---|---|---|---|
| ISO 9001 | Quality management system: documented processes, traceability, corrective action | Everyone — the baseline | Ask for the certificate number + issuing body; confirm with the certifier's registry |
| amfori BSCI | Social audit: working conditions, hours, wages, safety. An audit rating, not a "certification" | EU-facing brands; any brand doing diligence | Ask for the audit report + amfori ID; factories can share the PDF |
| Sedex / SMETA | Same territory as BSCI (social + ethics), UK-centric | UK retail programs | Sedex membership number; SMETA report PDF |
| OEKO-TEX Standard 100 | Chemical safety of the fabric (not the factory) | Baby/kidswear, skin-contact basics | Certificate number on oeko-tex.com's public validity check |
| GOTS | Organic fibre content + processing chain | Only if you market "organic" | Licence number in the GOTS public database |
| GRS | Recycled content chain of custody | Only if you market "recycled" | Certificate via Textile Exchange registry |
| WRAP | US-oriented social compliance (12 principles) | US retail/licensed programs | WRAP's public facility list |
The Three-Check Rule for Small Brands
You do not need a factory with every logo. You need: (1) ISO 9001 — proves the factory runs on documented process rather than tribal knowledge; (2) one social audit (amfori BSCI or SMETA — they overlap heavily); (3) fabric-level safety documentation for your product category. Everything beyond that is claim-specific: GOTS only if the hangtag will say organic, GRS only if it will say recycled.
How Factories Fake It — and How to Catch Them
- Logo walls with no numbers. A page of certification logos with no certificate numbers, issuing bodies or expiry dates is decoration, not evidence. Ask for all three; a genuine holder answers in minutes.
- "Certified" when they mean "audited". BSCI and SMETA are audits with ratings, not certificates. A factory saying "BSCI certified" either does not understand its own compliance or hopes you don't — the honest wording is "amfori BSCI audited".
- Borrowed certificates. Trading companies sometimes show a partner factory's certificate. Check the legal name on the document matches the company quoting you.
- Expired documents. ISO 9001 certificates carry a 3-year cycle with surveillance audits. Check the dates.
Where FABRIOZA Stands (Stated the Honest Way)
We hold ISO 9001 certification and are amfori BSCI audited — documentation with numbers and dates is available on request, and we encourage you to verify it with the issuing bodies rather than take a logo's word for it. We deliberately do not display certifications we cannot document. Fabric test reports for specific orders are supplied with production. That verification-first attitude is exactly what you should demand from any factory — see our full vetting guide.
Frequently Asked Questions
What is the most important certification for a clothing manufacturer?
ISO 9001. It certifies the factory's quality management system - documented processes, traceability and corrective action - which predicts consistent production better than any product-level badge. Pair it with a social audit (amfori BSCI or SMETA) and you have covered quality and ethics.
Is BSCI a certification?
No - amfori BSCI is a social audit with a rating (A-E), not a certification. A factory saying 'BSCI certified' is using the wrong term; the accurate wording is 'amfori BSCI audited'. Ask for the audit report and rating.
Do I need a GOTS certified manufacturer?
Only if you will market the product as organic. GOTS certifies the organic fibre chain; using it when you don't make organic claims adds cost without benefit. For general skin-safety, OEKO-TEX Standard 100 on the fabric is the relevant check.
How do I verify a factory's ISO 9001 certificate?
Ask for the certificate PDF showing the certificate number, issuing body (e.g. SGS, TUV, Bureau Veritas) and expiry date, then confirm the number with the issuing body's registry or by emailing them. A genuine holder provides this within a day.
What certifications does FABRIOZA have?
ISO 9001 (quality management) and amfori BSCI social audit - documentation with numbers and dates available on request, and we encourage independent verification. We do not display badges we cannot document.
