Labels and certifications, compared on where they genuinely differ

What to take away

A buyer comparing two hangtags is usually comparing two different questions. One mark may certify where the cotton came from. Another may certify that the buttons do not leach lead. Neither says the other is false. The labels and certifications overview sets out the categories; this article names the programs and puts them side by side.

The named programs

GOTS (Global Organic Textile Standard). Covers organic fiber content, processing chemistry, wastewater, and social criteria across the supply chain. Textiles must contain at least 70 percent certified organic fiber; the "organic" grade requires 95 percent. Suits a brand whose main claim is fiber origin. Certification is per facility, per year, through approved certifiers.

OEKO-TEX STANDARD 100. Tests the finished article, or its components, for harmful substances against limit values. It says nothing about organic content, labor, or carbon. Suits a brand answering a chemistry question, especially for babywear and skin-contact textiles. OEKO-TEX is an association of independent textile testing institutes, and annual re-testing is required.

OEKO-TEX MADE IN GREEN. Combines STANDARD 100 with STeP, the OEKO-TEX facility standard for sustainable production. STeP covers chemical management, environmental performance, and social responsibility at a site. The label carries a product ID a shopper can trace to the production site. Suits brands that want chemistry plus site-level process control in one mark.

Cradle to Cradle Certified. A multi-attribute product standard scoring material health, product circularity, clean air and climate protection, water and soil stewardship, and social fairness. Each category earns Basic, Bronze, Silver, Gold or Platinum. Suits brands designing for disassembly or material reuse. A Bronze mark on one category is not a Bronze product.

EU Ecolabel. A voluntary European government label with published criteria per product group, including textiles. Criteria are lifecycle-based and revised on a cycle, so a license must be checked against the current version. National competent bodies grant licenses. Suits brands selling into the EU that want a recognized public mark.

FTC Green Guides. Not a certification. The Guides govern how environmental claims may be worded in US marketing, including "recycled," "compostable" and "biobased." The FTC has brought cases over overstated biodegradable and bamboo-textile claims. Suits every brand, because the wording rules apply whether or not a certificate exists.

bluesign and ZDHC. bluesign approves chemicals, processes and sites against input-stream criteria. ZDHC publishes the Manufacturing Restricted Substances List (MRSL) and runs a chemical-management gateway. Both suit mills and dyehouses more than finished-garment labels.

Global Recycled Standard (GRS). Textile Exchange runs it. It certifies recycled content plus chain of custody, social and environmental criteria, and chemical limits. Suits brands making a recycled-polyester claim. The content percentage is verified; the garment's recyclability at end of life is not.

ISO 14001. A site-level environmental management system standard. It says a facility runs a documented system for managing its environmental impact. It says nothing about the fiber, the chemistry of the fabric, or the finished garment.

Side-by-side

EPA describes ecolabels and standards as single-attribute or multi-attribute and run by government, nonprofit or private bodies. That tells you scope, not strength. The European Commission describes the EU Ecolabel criteria model as voluntary, product-group based and periodically revised.

Where the marks actually diverge

Scope. GOTS covers a supply chain. STANDARD 100 covers an article. STeP and ISO 14001 cover a factory. Reading one as the other is the most common hangtag error. Settling on labels and certifications without wasted steps starts with naming which of those three scopes the claim needs.

Evidence. STANDARD 100 rests on a lab report. GOTS rests on an annual audit of records and sites. Cradle to Cradle rests on a category-by-category assessment, administered by the Cradle to Cradle Products Innovation Institute. A lab report and an audit answer different questions.

Currency. OEKO-TEX certificates expire annually. GOTS certificates are annual. EU Ecolabel licenses track the current criteria version. A mark photographed in 2022 may be void in 2026.

Inference. A "certified biobased" result measures biobased carbon content. Shoppers read it as biodegradable. The biofabricated routes comparison works through what that number leaves out.

Worked example: a recycled-polyester tee

A brand claims "made with 50 percent recycled polyester" on a US hangtag.

Four documents, four different questions. The hangtag can carry all four only if each scope is stated.

Choosing between them

Weight legal fit first. Claim wording must survive the FTC Green Guides, and the mandatory label must meet the market's fiber and care rules. Then run the mark through seven gates:

Record why a familiar mark was not selected when its criteria miss the product's main risk. The garment comparison framework applies the same gates.

Two marks with clear scopes beat six logos with none. A shopper who cannot tell what a symbol certifies has been given decoration, not information.

Common questions

Is GOTS better than OEKO-TEX?

They answer different questions. GOTS covers organic fiber, processing and social criteria across the chain. OEKO-TEX STANDARD 100 tests the finished article for harmful substances. A garment can hold both, and often does.

Can a factory certificate be used on a product page?

Only with wording that names the site and the standard. "Made in a STeP-certified facility" is accurate if the certificate is current and the named factory made that garment. A logo alone implies the product is certified, which it is not.

Does the EU Ecolabel replace GOTS for European sales?

No. The EU Ecolabel is a multi-attribute government mark with its own product-group criteria. GOTS is a private fiber-and-processing standard. A brand selling organic cotton in the EU may hold both.

How do I check a certificate is still valid?

Use the issuing body's registry. GOTS, OEKO-TEX and GRS all publish certificate lookups by number or company. Check the scope wording, the product or facility named, and the expiry date before the mark goes on a hangtag.
