OEKO-TEX® STANDARD 100 Guide for Importers & Manufacturers

Posted on Leave a comment


OEKO-TEX® STANDARD 100 restrics chemicals, heavy metals, and other harmful substances in textiles. While OEKO-TEX® STANDARD 100 is voluntary, it is based on REACH and other regulations which make the standard a preferred choice for many brands.

In this guide, we explain which regulations STANDARD 100 is based on, and the conditions you must meet to use the label. We also cover product classes, certification, and more.

The OEKO-TEX® STANDARD 100 is a well-known textile certificate issued by OEKO-TEX®. If a textile product bears the OEKO-TEX® STANDARD 100 label, it means that every part of the product was tested per the test criteria concerning harmful substances set by the standard.

Textile products carrying the label are deemed to be better for human health for the following reasons:

a. Strict criteria catalog – Every part of the product, from the coating and stitching to the application and zipper, has to comply with OEKO-TEX® STANDARD 100’s test criteria

b. Global standardization – OEKO-TEX®’s test criteria are globally standardized and updated at least once every year with new scientific knowledge or requirements

c. Independent test institutes – the OEKO-TEX®’s partner test institutes that issue the test reports and certificates are independent and neutral

d. Label check – The OEKO-TEX® STANDARD 100 label has a certificate number that businesses and consumers can use to check the validity of the product’s certification

Product scope

OEKO-TEX® classifies covered products into four classes based on their intended utilization. Products in each class have to fulfill various requirements. For example, the applicable limit values concerning restricted substances might be different according to the class.

Product class 1

Product class 1 covers textile products for babies and toddlers and has the strictest substance limit values and requirements.

Product class 2

Product class 2 covers products that are in direct contact with the skin to a great extent and includes products such as the following:

  • Blouses
  • Shirts
  • Underwear
  • Mattresses

Product class 3

Product class 3 covers products that have little to no skin contact and covers products like:

  • Jackets
  • Belts
  • Vests

Product class 4

Product class 4 covers decoration materials such as home textile products and furnishing accessories, which includes:

  • Curtains
  • Table cloths
  • Upholstery fabrics

Substance Restrictions

OEKO-TEX®’s partner institutes test every part and element of the final textile product for harmful substances per the test criteria in the standard’s criteria catalog. This might include the following parts:

  • Threads
  • Buttons
  • Zippers
  • Linings
  • The outer material’s prints and coatings

The standard sets limit values that comply with the substance restrictions set by several regulations and hazardous substance lists, such as the ones listed below.

REACH Regulation (EU)

The OEKO-TEX® STANDARD 100’s limit values comply with several substance restrictions set by REACH, which regulates dangerous chemicals – and articles that might contain such chemicals, in the European Union.

Annex XVII

Annex XVII of REACH is a list of harmful substances that are either restricted or banned from use in products for sale in the EU.

Products that comply with the OEKO-TEX® STANDARD 100’s requirements must meet the restrictions set in the annex.

Annex XIV

Annex XIV, known as the Authorization List, is a list of substances subject to authorization under REACH. Companies can continue using a substance on the Authorization List after the “sunset date” by:

1. Applying for authorization before the latest application date, and

2. Obtaining a “positive authorization decision” by the European Commission

The substance restrictions of the OEKO-TEX® STANDARD 100 comply with the applicable entries set by Annex XIV of REACH.

SVHC Candidate List

According to the European Chemicals Agency (ECHA), Substances of Very High Concern (SVHC) are substances that might be:

  • Carcinogenic
  • Mutagenic
  • Toxic
  • Persistent
  • Bioaccumulative

SVHCs can permanently and irreversibly impact the environment and human health. As such, the ECHA requires importers and manufacturers of articles that contain SVHC in an amount greater than 0.1% to register their product into the SCIP database and inform customers that make an inquiry about SVHC’s content.

The standard covers SVHCs that are relevant to textile products. Specifically, OEKO-TEX® STANDARD 100’s criteria ensure that “no communication duties are necessary along the supply chain regarding the SVHC substances”.

An exception might be made in rare situations. In this case, the exception should be clearly stated in the scope of the certificate.

Persistent Organic Pollutants (POPs) Regulation (EU)

POPs are persistent and bioaccumulative chemical substances that build up through the food web and remain in the environment. The Persistent Organic Pollutants (POPs) Regulation restricts or prohibits using POPs that can endanger the environment and human health.

OEKO-TEX® STANDARD 100 ensures compliance with the POPs Regulation.

GB 18401 – National general safety technical code for textile products (China)

The National Standards of the People’s Republic of China has published GB 18401 – National general safety technical code for textile products.

It contains methods for testing textile products that fall into one of three categories:

  • Intended for infants aged 36 months and under
  • Directly contact the skin
  • Have little to no skin contact

Products that comply with the OEKO-TEX® STANDARD 100 also need to respect the substance limitations set by the GB 18401 standard.

Zero Discharge of Hazardous Chemicals Manufacturing Restricted Substance List (ZDHC MRSL)

The Zero Discharge of Hazardous Chemicals Manufacturing Restricted Substance List (ZDHC MRSL) lists chemical substances prohibited from intentional use when processing textile materials; it covers formulations such as coatings, dyes, and finishing agents.

OEKO-TEX® monitors the ZDHC MRSL as well.

Apparel and Footwear International RSL (Restricted Substance List) Management (AFIRM)

The AFIRM limits the usage of certain substances in product categories such as the following:

  • Jewelry
  • Apparel
  • Footwear
  • Accessories
  • Sporting goods equipment
  • Wearables
  • Home textiles

AFIRM member brands must comply with such limitations. OEKO-TEX® also monitors the AFIRM.


OEKO-TEX®’s independent test institutes use the comprehensive criteria catalog to test textile products, including related accessories such as buttons, for harmful substances.

The tests account for many regulated and non-regulated substances which may harm human health, including the ones restricted by the regulations and standards that we mentioned in the previous section.

OEKO-TEX® updates the catalog yearly and expands upon it to include the latest scientific knowledge or statutory requirements.

The company has 17 independent partner institutes in Europe and Japan. We list a few of those institutes below:

  • Centexbel (Belgium)
  • Hohenstein Textile Testing Institute (Germany)
  • Shirley® Technologies Limited (United Kingdom)
  • Nissenken Quality Evaluation Center (Japan)

You can find the full list on this page.

OEKO-TEX® STANDARD 100 Certificate

Textile manufacturers can apply for a STANDARD 100 certificate by completing an application form and submitting it to their chosen OEKO-TEX® partner institute. The institute then contacts the manufacturer to request relevant documents, and the following occurs:

1. The selected institute examines the manufacturer’s documents and defines the audit’s scope and parameters of success.

2. The institute tests the textile products according to the OEKO-TEX® STANDARD 100’s criteria catalog titled.

3. If the product successfully passes the lab test, the institute provides the STANDARD 100 certificate and test report to the manufacturer

4. An OEKO-TEX® professional visits the manufacturer’s location to confirm the shared information and details. This visitation occurs either before or shortly after the manufacturer receives the certificate, which authorizes the usage of the OEKO-TEX® STANDARD 100 label

Test Report

As explained above, the manufacturer chooses an OEKO-TEX® partner institute to test its products for harmful substances and receives a test report if the product passes the tests.

The manufacturer needs this test report to prove that their textile products comply with relevant substance restrictions such as those in REACH’s Annex XVII and SVHC Candidate List.


The OEKO-TEX® STANDARD 100 label informs consumers that the textile product, including every component of said product, is “harmless for human health”. This is because it indicates that the product has undergone testing for harmful substances at an independent OEKO-TEX® partner institute.

The information on the label contains a certificate number. Businesses and consumers can enter this number into the dedicated field on the OEKO-TEX® Label Check page to check the validity of the product’s certificate.


Below we provide information regarding several frequently asked questions about OEKO-TEX® STANDARD 100.

Is OEKO-TEX® STANDARD 100 mandatory in the EU?
