OEKO-TEX in 2026: What the Updated Rules Mean When You Buy Certified Fabric

What OEKO-TEX STANDARD 100 is, and is not

STANDARD 100 by OEKO-TEX is a product certification: an independent institute tests an article, fabric, yarn, accessories, against a catalogue of limit values for harmful substances, and if it passes, the article can carry the label under a numbered certificate valid for twelve months. Articles are certified under product classes based on skin contact, from Class I for babies through Class II for direct skin contact, which is where most shirting and uniform fabric sits, to Classes III and IV for outer and decorative materials.

What it is not: a durability standard, a quality standard, or a sustainability chain-of-custody standard. A certified fabric can still shrink, fade or pill. The certificate answers one question, whether tested harmful substances in the article sit under the limit values, and answers it well. Buyers who treat the label as a general quality mark are asking it to carry more than it claims.

What changed in the 2026 update

OEKO-TEX updates its test criteria and limit values every year, publishes the changes at the start of the year, and brings them into force on 1 June after a three-month transition. The 2026 update, effective 1 June 2026, revised criteria and limit values across STANDARD 100, ORGANIC COTTON, ECO PASSPORT and the shared limit value catalogue.

The direction of travel is the same one EU chemical regulation is on: tighter control of per- and polyfluorinated substances, the PFAS family used in some water- and stain-repellent finishes, alongside ongoing tightening of other substance groups. Reporting on the 2026 catalogue notes the PFOS limit tightened to 1 mg/kg. Worth separating the two instruments, because only one of them is law: OEKO-TEX is a voluntary certification, while Commission Regulation (EU) 2024/2462 is a statutory REACH restriction with a hard date, catching PFHxA in clothing textiles for the general public from 10 October 2026. We cover that date and its carve-outs in the technical finishes guide. For the exact substance-by-substance values, the authoritative source is the current OEKO-TEX limit value document, since the catalogue changes annually and any list reproduced here would go stale.

The buyer-side consequence is simple: a certificate issued under the old catalogue and a certificate issued under the new one are both valid within their twelve-month terms, but renewals from June 2026 are tested against the stricter values. If your program specifies a repellent or technical finish, this is the year to ask the supplier whether that finish chemistry passes the current catalogue.

A second change lands in September, and it comes from EU law rather than from the test catalogue. Directive (EU) 2024/825, the EU directive on empowering consumers for the green transition, known as EmpCo, applies from 27 September 2026, member states having had until 27 March 2026 to transpose it. Among other things it bars sustainability labels that are not based on a certification scheme with independent third-party verification. OEKO-TEX announced a governance restructure on 19 August 2026 in response: the organisation converts to a public limited company, adopts a statute of independence with an independence council and an anonymous whistleblowing channel, and separates standard setting from conformity assessment so that certification decisions sit with accredited bodies. Testing, auditing and certification services continue unchanged for existing holders.

For a fabric buyer this changes nothing about the certificate itself or how you verify it. It matters in one situation: if the finished garments are marketed in the EU, the label your customer prints has to stand up under EmpCo, so the certificate behind it needs to be current and to genuinely cover the article being sold. Vague green wording with no scheme behind it is exactly what the directive targets. Our sustainability certifications guide covers the wider label landscape, and EU textile EPR for Indian exporters covers the other EU obligations landing on the same programs.

How to actually verify a certificate

• Ask for the certificate number and the name of the certifying institute, not a scan of a label.
• Enter the number in the OEKO-TEX validity check on oeko-tex.com and confirm it is current, certificates run twelve months and lapse quietly.
• Check the certificate holder: it should be the company selling you the fabric or a named upstream supplier whose article your fabric actually is, not an unrelated trader.
• Check the product class against the garment: Class II for anything worn against skin, which covers shirts, scrubs and most uniform layers.
• Check the article description covers your construction and shade range, a certificate for one article does not automatically cover a different quality from the same mill.

When a uniform program needs it, and when a test report is the better ask

OEKO-TEX belongs in the specification when the end market or the wearer profile demands it: export programs into markets where retailers require it, garments for children, and healthcare or hospitality programs whose procurement policies name it. In those cases the certificate is a gate, and it is the supplier's job to hold it.

For most Indian institutional uniform programs, the worries that actually surface, shrinkage after industrial laundering, colour fastness through a year of daily washes, pilling on trouser seats, are not answered by OEKO-TEX at all. They are answered by per-lot test reports against an agreed protocol. A program that asks for a certificate it does not need, and skips the lot report it does need, has the paperwork backwards.

Where we stand

We do not currently hold OEKO-TEX certification, and we say so rather than implying otherwise. We are ISO 9001:2015 certified, weaving runs in-house at our unit in Village Atoon, and dyeing, processing, finishing and testing run through partnered processing houses in Bhilwara. Per-lot test reports for shrinkage, colour fastness, GSM and strength are available on request against an agreed protocol, which for most uniform programs is the document doing the real work.

If a program genuinely requires certified inputs, the honest conversation is about which certification, held by whom in the chain, at which stage, and we would rather have that conversation at quote stage than discover the requirement at dispatch.

FAQ

Frequently asked questions

What does OEKO-TEX STANDARD 100 actually certify?

That a specific tested article sits under limit values for a catalogue of harmful substances, under a product class based on skin contact. It does not certify durability, shrinkage, colour fastness, or where and how the fabric was made. Those need test reports and supplier disclosure respectively.

What changed in the OEKO-TEX 2026 update?

OEKO-TEX revised test criteria and limit values across STANDARD 100 and its other certifications, effective 1 June 2026 after a three-month transition. The tightening continued on the PFAS chemical family used in some repellent finishes, with reporting noting the PFOS limit at 1 mg/kg. The current limit value catalogue on oeko-tex.com is the authoritative reference.

Does anything change for OEKO-TEX labels in the EU in 2026?

Yes. Directive (EU) 2024/825, the EmpCo directive, applies from 27 September 2026 and restricts sustainability labels that are not based on a certification scheme with independent third-party verification. OEKO-TEX announced a governance restructure on 19 August 2026, separating standard setting from conformity assessment, to keep its labels compliant. Certificates, the online validity check and testing services are unaffected.

How do I check whether an OEKO-TEX certificate is genuine?

Ask for the certificate number and look it up in the validity check on oeko-tex.com. Confirm it is current, that the holder is actually in your supply chain, that the product class fits the garment, and that the article description covers the specific quality you are buying.

Is Benny Cotts fabric OEKO-TEX certified?

No. We are ISO 9001:2015 certified and provide per-lot test reports on request for the parameters uniform programs actually specify, such as shrinkage, colour fastness and strength. If your program requires a certified input, tell us at enquiry stage so the requirement can be addressed honestly in the quote.

Does a fabric need OEKO-TEX to be safe to wear?

No. The certification is one way of demonstrating tested limits on harmful substances, and some markets and retailers require it. Plenty of safe fabric is sold without it, and dye and finish chemistry is also governed by the processing house's own compliance. Match the paperwork to the requirement rather than treating any single label as a universal safety gate.
