GOTS, OEKO-TEX & BSCI: which certifications matter, and how to verify them
Walk any sourcing marketplace and you'll see the same badges everywhere: GOTS, OEKO-TEX, BSCI. They're claimed constantly — and faked often enough that the claim alone is worthless. Here's what each certification actually means, when it matters for your brand, and how to confirm it's real before you rely on it.
The three you'll see most
GOTS — Global Organic Textile Standard
GOTS certifies that a textile is made from organic fibres and that the whole supply chain meets environmental and social criteria. It's the standard behind a credible 'organic cotton' claim. If your brand markets organic or sustainable materials — especially into the EU or US — this is the one buyers and conscious customers look for.
OEKO-TEX Standard 100
OEKO-TEX Standard 100 tests the finished product for harmful substances — it's about safety, not organics. A Standard 100 label means the item was tested against a list of restricted chemicals. It's the most widely recognized textile safety certification, and a reasonable baseline to ask for on anything worn against skin.
amfori BSCI
BSCI is a social-compliance audit of the factory's labour practices — working conditions, hours, pay, safety. It says nothing about your product's quality or materials; it's about how ethically the place is run. If you make ethical-sourcing claims, this (or a comparable audit like SMETA) is the evidence behind them.
A few others worth knowing in one line each: ISO 9001 is a quality-management system certification; GRS (Global Recycled Standard) verifies recycled content; WRAP is another factory-level social-compliance certification common in apparel.
Claimed is not certified
This is the trap. A supplier writing 'OEKO-TEX certified' on their page means nothing on its own. In practice, a large share of claimed certifications are expired, belong to a fabric supplier rather than the factory you're talking to, cover a different product than the one you're buying, or are simply fabricated. The badge is a claim until you've seen a valid certificate and checked it.
How to verify each one
Every major certification has a public way to confirm it. Use them:
- GOTS: search the public GOTS database of certified entities. Confirm the company name matches your supplier and that the scope covers your product category.
- OEKO-TEX: every valid certificate has a number. Validate it through OEKO-TEX's online certificate check — it shows the holder, the scope, and whether it's still in date.
- BSCI / amfori: there's no public lookup; ask the supplier for the actual audit report and the audit date. A factory that's genuinely audited can produce it. Treat 'we're BSCI' with no report as unproven.
- On any certificate, check three things: the exact entity name, the scope (what's actually covered), and the validity dates. Then confirm the certified entity is the same company that will make your order.
We cross-check supplier certifications against the issuer registries and flag anything that's claimed but unverified, so you can see at a glance which credentials hold up and which are just text on a page. See how it works.
What a certificate does not tell you
Even a real, current certificate has limits. Scope matters — a GOTS certificate covering a supplier's organic line says nothing about the conventional fabric they'd use for your order. Chain of custody matters — certified inputs can still be mixed with uncertified ones downstream. And no certification guarantees that this specific production run will meet it. Certificates narrow your risk; they don't remove it. Pair them with the rest of your vetting — including confirming you're dealing with the actual manufacturer.
