Oeko-Tex will launch its "Trust in Every Thread" campaign on Oct. 12, positioning its certification system as compliant proof for brands facing the EU's new restrictions on sustainability labelling.

The timing is commercial, not coincidental. Rules under the EU's Empowering Consumers for the Green Transition Directive (ECGT) took effect Sept. 27, prohibiting sustainability labels unless a public authority establishes them or they rest on a qualifying certification scheme.

For private schemes such as Oeko-Tex, the directive sets hard conditions:

• Publicly available criteria
• Independent monitoring of compliance
• Procedures to withdraw or suspend a label when requirements are breached
• A monitor independent of both the scheme owner and the company using the label

For brands and sourcing teams, the practical effect is that labels surviving the directive must show documented, independently checked criteria — a compliance question that now sits squarely in vendor selection.

What does Oeko-Tex's system actually verify?

The Zurich-based organization's Standard 100 certification requires articles to meet limits for more than 1,000 harmful substances. Criteria cover components including buttons, zippers and thread — not just fabric — and Oeko-Tex reviews limit values at least once a year.

Strictness scales with skin contact and intended use. Products for babies and children up to age three face the tightest limits, a tiering suppliers of kidswear already know from audit scopes.

Oeko-Tex says it retests a quarter of its certificates through its quality control program, with oversight that includes site visits and audits.

"Trust is not a word you can put on a label. It is built in the places nobody looks: in the button, the zipper, the thread, in the limits we revise every year because the science moves, in a quarter of our certificates we go back and retest," said Inga Bleyer, Oeko-Tex's head of marketing and communication, in a statement. "A garment that has passed through that is not a louder promise than the one next to it. It is a verified one."

How has the organization restructured for the directive?

Oeko-Tex has separated standard setting from conformity assessment, announced Aug. 19, alongside a new independence council and an anonymous whistleblowing system. The move aligns its governance with the ECGT requirement that monitoring sit outside the scheme owner.

"Consumer protection begins with trust, and trust only arises when what is claimed is independently verified. We anchor independence even more firmly and make it transparently verifiable for everyone," CEO Alfred J. Beerli said in a statement.

The organization's Made in Green label goes beyond Standard 100's product-level substance testing. It combines certification with requirements for manufacturing facilities under the Step program, which assesses environmental and social conditions, and ties each item to a product ID or QR code showing where and how it was made.

Demand data backs the compliance angle: Oeko-Tex reported more than 13 percent growth in Made in Green demand in its 2025-26 annual report, announced in September.

What should brands watch on claim scope?

The directive also narrows what a label can imply. Brands cannot extend a benefit tied to one feature into an environmental claim about the whole product, and vague terms such as "eco-friendly" face restriction.

The campaign pushes consumers toward three checks: the claim, the proof, and access to that proof. Oeko-Tex's existing Label Check tool lets shoppers scan a QR code or enter a certificate number or product ID to verify a label — putting certification transparency directly in the retail channel.

As enforcement of the ECGT directive begins, certification schemes that can demonstrate independent verification and traceable proof are likely to gain share in brand sourcing specifications.
