Which textile certifications actually matter

The most credible standard for organic textiles. Covers the whole chain from fibre to finished garment, with chemical and social criteria. Two label grades: “organic” (at least 95% certified organic fibre) and “made with organic” (at least 70%).

Watch out: Every processing step must be certified, and each order needs a transaction certificate.

Check it: GOTS public database

Tracks the amount of organic material in a product from farm to finished item. Useful for blends with partial organic content that don’t qualify for GOTS.

Watch out: Chain of custody only: no chemical or social requirements, unlike GOTS.

Verifies recycled content through the chain and adds social, environmental and chemical criteria. Covers pre- and post-consumer material. The lighter RCS checks content only.

Watch out: Products need at least 50% recycled content to carry the GRS label.

Animal welfare and land management on sheep farms, with chain of custody through spinning, knitting and sewing. The basis for any credible responsible-wool claim on merino or wool knitwear.

Watch out: Covers the wool fibre, not the rest of the garment.

Lab tests every component of the finished article (fabric, thread, buttons, labels) against a list of regulated and unregulated harmful substances. Four product classes, from baby articles to decoration material.

Watch out: A safety label: it says nothing about organic or recycled fibre, or working conditions.

Check it: OEKO-TEX Label Check

The EU’s official environmental label. Criteria on fibres, restricted chemicals, water and energy in production, and durability. Harder to get than OEKO-TEX, with strong institutional credibility.

Watch out: Few garment makers hold it, so expect a smaller choice of factories.

Certifies the production site across six areas: chemical management, environmental performance, environmental management, occupational health and safety, social responsibility and quality management.

Watch out: A site certificate: it doesn’t test your finished garment.

Check it: OEKO-TEX Label Check

Controls chemicals and resource use at the input stage of wet processing: dyeing, printing, finishing. Most relevant for synthetic and performance fabrics.

Watch out: Mostly held by mills and chemical suppliers, less often by sewing factories.

How the factory manages waste, water, energy and emissions, with targets and yearly audits. Increasingly asked for by large retail buyers.

Watch out: About how the site runs, not about your product.

Check it: IAF CertSearch

The factory environmental assessment from Cascale (formerly the Sustainable Apparel Coalition): energy, water, waste and emissions, often verified by a third party. Larger brands use it to score suppliers.

Watch out: An assessment score, not a certificate or a consumer label.

Check it: Ask the factory for its verified FEM score

Documented processes for consistent output, error tracking and corrective action. One of the most useful things to ask a new supplier for.

Watch out: Proves the system exists, not that every garment is perfect: you still need a QC plan.

Check it: IAF CertSearch

Restricts substances of very high concern and specific chemicals, such as certain azo dyes and nickel in metal trims, in products placed on the EU market.

Watch out: Not a certificate: a legal duty. Ask for test reports on dyed and treated fabrics and on trims.

Check it: ECHA restriction list

Required for textiles classed as personal protective equipment (PPE Regulation) or medical devices, such as high-visibility workwear or protective gloves.

Watch out: Regular fashion never carries CE marking: using it without a reason is itself a breach.

Check it: EU NANDO database of notified bodies

Tests sun protection under real-use conditions: stretched, wet and worn. The basis for UPF or sun-protection claims on swimwear and sportswear.

Watch out: Only needed if you make a UV claim.

Check it: UV Standard 801

One of the strictest social standards: child and forced labour, health and safety, freedom of association, discrimination, working hours and pay. Audited by accredited bodies.

Watch out: Certifies the site; subcontracted steps need their own checks.

Check it: SAAS certified facilities

A membership programme for brands, not a factory certificate. Members commit to improving conditions at their suppliers and are assessed every year. Strong reputation in European fashion.

Watch out: The brand is the member: a factory can’t be “Fair Wear certified”.

Check it: Fair Wear member list

Fair wages, safe conditions and the right to organise along the textile chain, with audits by FLOCERT. More common in cotton farming than in garment making.

Watch out: Fairtrade cotton is a different, farm-level label.

Portugal’s national standard for social responsibility management systems, published by IPQ. Not textile-specific, but a sign of structured social management at a Portuguese company.

Watch out: Little known outside Portugal: pair it with an international standard for export buyers.

Check it: Ask for the certificate from an IPAC-accredited body
