What Textile Certifications Actually Cover: Product Safety, Organic Content and Chain of Custody

Start with the question the scheme is designed to answer

Certification is evidence within a boundary. It is not a general adjective for “good”, “safe” or “sustainable”. Before comparing suppliers, write the requirement as a question: product chemistry, certified organic percentage, certified recycled input, physical cotton origin, or an organisational custody system. Then request the evidence that answers that exact question.

OEKO-TEX® STANDARD 100: a certified article and product class

OEKO-TEX describes STANDARD 100 as a label for textiles tested for harmful substances, from yarn to finished product. Its requirements become stricter as skin contact intensifies: Product Class 1 is for babies and children up to three, Class 2 for direct skin contact, Class 3 for products without direct skin contact and Class 4 for decorative materials.

For a towel, ask for the certificate number, holder, certified article description, product class, included materials or components, applicable annex or test programme, and validity. Check the number through the scheme owner's Label Check rather than accepting a logo image. Certification of a yarn, dye or component does not automatically mean a finished towel is labelled and certified; the certificate scope must cover the article being claimed.

STANDARD 100 does not certify cotton as organic, verify recycled-content chain of custody or prove absorbency, colourfastness, shrinkage or service life. Those are separate specification and test questions.

GOTS: organic fibre plus certified processing and custody

GOTS Version 8.0 covers certified organic fibre inputs and subsequent processing requirements, including environmental, chemical, social, quality, traceability and labelling provisions. Its label grades are based on certified fibre content: at least 95% for “Organic” or “Organic in-conversion”, and at least 70% for “Made with (x%) organic materials” or its in-conversion equivalent, excluding accessories as defined by the standard.

A certified company is not evidence that every towel it sells is GOTS-certified. GOTS advises buyers to examine the scope certificate for the supplier, sites, operations, products and validity, and to obtain a transaction certificate covering the applicable shipment. Its certified-supplier guidance explicitly warns that not all products made or sold by a certified operation are certified.

Version matters during transition. GOTS reports that Version 8.0 was released in March 2026 and becomes mandatory on 1 March 2027. A buyer reviewing an October 2026 certificate should therefore identify the edition actually audited, check the scheme's transition rules and avoid mixing requirements from two versions.

GRS: recycled content, chain of custody and processing controls

Textile Exchange says the Global Recycled Standard sets criteria for third-party certification of recycled materials and chain of custody, with additional social, environmental and chemical requirements related to processing. Its public guidance distinguishes certification use from consumer-facing claims: the product-related claim threshold and the claim policy must be satisfied; a scope certificate alone is not permission to put a logo on a towel.

Ask for the current scope certificate, the facilities and processes it covers, certified product categories and material composition, and the transaction certificate or electronic transaction record connecting the material to the shipment. For artwork, confirm the certified percentage, certificate or licence identifier, certification body and claim approval. Textile Exchange's claims guidance says product-related claims are submitted to the certified organisation's certification body for approval.

GRS is also in a version transition. Textile Exchange's official standards update gives GRS 5.0 an effective date of 1 July 2026 and a mandatory date of 31 December 2026. The owner describes the revision as targeted changes to reclaimed-material documentation and tracking. Record the version shown on the certificate and confirm current transition and claims-policy requirements rather than assuming an older checklist still governs.

Better Cotton: distinguish mass balance from physical custody

The Better Cotton Initiative's Chain of Custody Standard v1.2, effective 6 January 2026, allows mass-balance and physical sourcing models. The physical models include segregation and controlled blending; mass balance connects demand with programme supply through an administrative accounting model. A mass-balance order must not be described as proof that physical Better Cotton is present in a particular yarn or towel.

Claims are governed separately. The current Claims Framework v4.1 defines eligibility and approval, and the former mass-balance on-product mark was phased out by May 2026. Better Cotton's current label explanation limits the product label to eligible certified retailer and brand members sourcing traceable cotton through segregated physical custody models. Buyers should confirm the seller's role, certification or platform status, custody model, origin and volume records, and the specific claim permission.

Better Cotton is not an organic standard and does not replace chemical product-safety testing. Its farm assurance, custody evidence and claims rules should be described only in the approved scheme language.

A seven-point certificate and claim check

1. Name the intended claim. Write the exact B2B, label, web or consumer wording before selecting evidence.
2. Match the entity and site. Confirm legal name, address and every processing or trading site relevant to the order.
3. Read the scope. Check standard, version, product categories, materials, processes, product class or custody model.
4. Check issuer and status. Verify the certification body is scheme-approved and the certificate is current in the owner or certifier database.
5. Connect the order. Obtain product annexes, transaction certificates, platform records or other scheme-required evidence for the actual SKU, quantity and shipment.
6. Approve the claim. Follow the current logo, percentage, identifier and approval rules; certification and marketing permission are not interchangeable.
7. Keep other requirements separate. Fibre labelling, destination law and towel performance still need their own specification, tests and compliance review.

Add these checks to the wider towel-manufacturer evaluation. Use the fibre-content guide to distinguish finished composition from feedstock and marketing claims. A scheme claim must never obscure the legally required fibre declaration.

Frequently asked questions

Does a certified factory mean every towel is certified?

No. Check the certificate's entity, site, product and process scope, then obtain the order- or shipment-level evidence required by the scheme.

Is OEKO-TEX® STANDARD 100 an organic certification?

No. It addresses harmful-substance testing of a defined textile article under a product class. Organic fibre and custody claims require separate evidence.

Are GOTS and GRS interchangeable?

No. GOTS is built around certified organic fibres and their processing chain; GRS is built around certified recycled material, custody and additional processing requirements. Each has its own thresholds and claim rules.

Does Better Cotton mass balance mean the towel contains physical Better Cotton?

No. Mass balance is an administrative chain-of-custody model and must not be represented as physical content in a particular product. Physical-product claims require an eligible physical custody route and current claim approval.

What is the minimum evidence to retain?

Keep the current scope or product certificate, verification result, relevant product appendix, order-level transaction or platform evidence, approved claim artwork and the standard and policy versions used for the decision.
