STANDARD 100 means safe for human ecology.

STANDARD 100 by OEKO-TEX® is a globally standardized, independent testing and certification system for raw, semi-finished and finished textile products at all processing levels, and their accessories. Products that have been successfully tested for harmful substances are awarded the STANDARD 100 label for clear and efficient customer communication. The certificate provides independent verification and reputation protection for B2B partners.

Testing for harmful substances with STANDARD 100 incorporates important legal regulations, numerous chemicals that pose a risk to health (including some that are not yet legally regulated) and a wide variety of health care parameters.

STANDARD 100 Benefits:

  • A practical tool for quality assurance
  • Consumer protection with textile products that are safe for human ecology and legally compliant - without expending internal resources
  • The OEKO-TEX® criteria catalogue is applied consistently worldwide and provides standardized requirements for purchasing and delivery
  • Many retailers and brands have Restricted Substances Lists (RSLs) based on STANDARD 100 and accept certification in lieu of additional testing
  • As a 3rd party verified label, STANDARD 100 is a helpful marketing tool for transparently promoting product stewardship efforts
  • The built in transparency increases product safety and saves time, especially for companies with extremely short production cycles and expensive internal quality assurance systems
  • The modular principle of STANDARD 100 facilitates testing and certification of textile products at every processing stage. Duplicate testing costs are avoided by using certificates from prior stages – even for products with complex structures


  • To provide the consumer with a reliable, 3rd-party label for non-hazardous products that are tested in accordance with strict global standards to protect from harmful substances in textiles
  • To provide targeted support for companies in the textile chain with human-ecological product safety, based on a scientific criteria catalogue and neutral laboratory tests
  • To simplify and accelerate supplier relationships for manufacturers and retailers who want to ensure product safety for their customers
  • To achieve legal conformity for importers, retailers and manufacturers

OEKO-TEX® is based on a modular system. Certification is available for every stage of the textile chain and certificates from prior stages are recognized downstream. This means that costs are shared throughout the supply chain and traceability enhanced.

The OEKO-TEX® criteria catalogue contains a wide variety of test parameters that consider all ways a substance can be absorbed (skin, mouth, breathing). The central components of STANDARD 100 - requirements, limit values (IV and VI) and test methods - are based on science. In many cases, the test criteria and limit values go far beyond applicable international standards. The inclusion of potentially harmful substances not yet legally regulated reflects the pioneering role.

STANDARD 100 tests for harmful substances based on the product's purpose. The more intensive the skin contact and the more sensitive the skin, the stricter the human-ecological requirements.

Including the term “organic” in the STANDARD 100 by OEKO-TEX® certificate scope is optional.

If descriptions such as “organic” or “made of organically grown cotton” are included on a STANDARD 100 certificate, the products have been tested for genetically modified organisms (GMOs) during the OEKO-TEX® laboratory tests.

This gives you and your customers confidence that your organic cotton products actually contain what they claim - genuine organic materials. If requested, the GMO test is also available for products made with conventionally grown cotton.

Requirements if declared:

Organic Components

All pre-certified main component materials made of cotton must also contain the term “organic” in the scope. Accessories are exempt.

Certificate of Origin

Valid organic origin certificate submitted with the application for STANDARD 100 by OEKO-TEX® certificate

GMO Testing

Negative GMO test results in addition to the regular testing program for STANDARD 100 by OEKO-TEX®


Hohenstein has lent its GMO testing method to the other OEKO-TEX® institutes so that organic cotton products from all levels of the supply chain can be verified.

If a certified product contains recycled materials, there are additional requirements:

  • A minimum amount of recycled content ( ≥20% )
  • Different test programs depending on the origin of the material
  • Additional background information

A hangtag is available to advertise recycled materials in the STANDARD 100 by OEKO-TEX® certified product. Certificate owners can download a customized version from the myOEKO-TEX® portal.

The article description on the certificate is based on a representative selection of samples which must cover the entire product group to be certified.  An incomplete sample selection may lead to a restriction of the certified article group.


A STANDARD 100 certificate is valid for 12 months and can be renewed annually. We recommend starting the renewal process up to three months before expiration to ensure continuous product safety and smooth process along the modular OEKO-TEX® system. Many downstream certifications are dependent on pre-certified components from suppliers.

To ensure consistent safety of certified products, an approved quality management system must be in place. Qualified auditors verify systems during on-site quality assurance meetings. These meetings occur within the first year of certification and every third year thereafter.

In addition to internal quality assurance programs, the certified company agrees to the declaration of conformity during application. This agreement allows OEKO-TEX® institutes to conduct control tests.

Each year, Hohenstein control tests at least 25% of certified products. Previously certified materials are re-tested during certification processes for downstream products. Random samples of OEKO-TEX® certified products are purchased from stores and tested again in the laboratory. In addition, independent auditors commissioned by OEKO-TEX® conduct unannounced site inspections to assess on-site quality assurance in the facilities.

A STANDARD 100 by OEKO-TEX® certificate and label are awarded only when all the component parts meet the test criteria. Finished goods must have their own certification, even if all the individual components have already been certified.

Since the STANDARD 100 label is a protected trademark, all companies using the label must comply with the labeling rules. Forgery and misuse of the trademark can be prosecuted under criminal and civil law.

A STANDARD 100 label is only valid if the test number and the responsible testing institute are shown. These details must also correspond to the company’s own certificate.

For B2B purchasers, a STANDARD 100 label applied to a product is not sufficient proof of successful testing. Buyers should always require the supplier to submit a valid OEKO-TEX® certificate. The details on the STANDARD 100 label (test number and test institution) must correspond to those on the certificate and the product must be included in the certificate scope.
