Broad sustainability language is getting harder to defend. What holds up better is a cleaner structure: separate product safety, responsible production, traceability, and due diligence, rather than blending them into a single vague promise.
That is where the OEKO-TEX® modular system becomes useful. It helps turn broad messaging into specific, checkable claim layers. That direction also aligns with the wider EU shift toward stricter claim substantiation, more structured product information, and stronger due diligence expectations.
1. Start with product safety
Product safety needs precise wording.
OEKO-TEX® STANDARD 100 is a certification system for textiles tested for harmful substances. OEKO-TEX® LEATHER STANDARD does the same for leather articles. OEKO-TEX® ORGANIC COTTON offers organic cotton verification from farm to product, including GMO and harmful substance testing. OEKO-TEX® ECO PASSPORT applies to chemicals, colourants and auxiliaries used in production.
The cleanest language here is simple: tested for harmful substances.
That may help support relevant chemical compliance requirements, including REACH-related requirements
Safety is one claim type. Keep it there.
2. Build responsible production at the facility level
The next question is how the product was made.
OEKO-TEX® STeP certifies production facilities in the textile and leather industry. It covers the following areas:
- Chemical management
- Environmental performance
- Environmental management
- Social responsibility
- Quality management
- Health & safety
For brands, that matters at the site level. Map the relevant stages, including spinning, weaving, dyeing, finishing, cut and sew, and tannery operations, and use OEKO-TEX® STeP as the audited basis for responsible production claims.
That kind of facility-level evidence is also more in line with the EU due diligence expectations, including CSDDD (Corporate Sustainability Due Diligence Directive)-related developments.
3. Use MADE IN GREEN for product-level claims
If the claim appears on the product, the proof must accompany it.
OEKO-TEX® MADE IN GREEN is a label for textiles and leather goods that are tested for harmful substances and manufactured under sustainable and socially responsible conditions. The products are also traceable through a unique product ID or QR code.
That combination matters. It connects product safety, responsible production, and traceability into a single, visible structure. It is a much stronger basis than generic wording like “sustainable product.”
It also fits the broader move toward more product-level transparency in Europe, including work around the DPP (Digital Product Passport) under ESPR (Ecodesign for Sustainable Products Regulation) and the ongoing revision of the EU Textile Labelling Regulation.
4. Make verification part of the claim
A claim gets stronger when someone else can check it.
OEKO-TEX® Label Check allows users to check the validity of OEKO-TEX® labels and certificates online.
For MADE IN GREEN, it also opens the traceability layer behind the product.
That makes it useful internally and externally. Teams can verify the use, scope, and validity of labels. Buyers and consumers can see what stands behind the claim.
This matters more as EU consumer rules move away from vague environmental messaging toward substantiated, verifiable claims.
5. Use the Buying Guide to support sourcing decisions
Claims do not start in marketing. They start with sourcing.
The OEKO-TEX® Buying Guide helps companies identify certified companies, products, brands and business partners. Used properly, it becomes part of the evidence trail: shortlist suppliers, document why they qualify and keep the sourcing logic on file.
That gives brands something more solid than supplier self-description and leaves a better record for buyer questions, internal reviews and future due diligence needs.
6. Tie everything into due diligence
Claims hold up better when they are embedded within a system.
OEKO-TEX® RESPONSIBLE BUSINESS is designed to support responsible business conduct and supply chain due diligence in the textile and leather industry. It focuses on identifying, preventing, and mitigating negative impacts across a company’s operations, supply chains, and business relationships.
That is the system layer in the modular setup. Product labels, facility certification, traceability, and sourcing tools work better when integrated into a single due diligence process.
Cleaner claims, less risk
For 2026, the stronger approach is not broader language. It is cleaner language.
- Use OEKO-TEX® products by function. Use OEKO-TEX® STANDARD 100, OEKO-TEX® LEATHER STANDARD, OEKO-TEX® ORGANIC COTTON and OEKO-TEX® ECO PASSPORT for product and chemical-related claims.
- Use STeP for responsible production at the facility level.
- Use MADE IN GREEN and Label Check for visible, verifiable product transparency.
- Use the Buying Guide and RESPONSIBLE BUSINESS to support sourcing and due diligence.
Important note: Any regulatory references should be understood as preliminary and subject to confirmation once the final legal texts and any subsequent OEKO-TEX® updates are available.
