Textile Certifications that Matter: RWS, GRS & Oeko-Tex

Finding or sourcing sustainable fabrics is relatively easy, as compared to making sure that the fabric or textile has been ethically sourced and is safe for human skin. This is why manufacturers’ or suppliers’ certifications are one of the most important factors. As a consumer or designer, you may want to be fully educated about the fabric’s sustainability and personal safety and about any textile that was obtained by animal abuse. This introduces standards and certificates. They help customers in knowing their source, fabric traceability, and supply chain transparency.

Understanding Textile Certifications

Among the most widely recognised and trusted standards are the Responsible Wool Standard (RWS), the Global Recycled Standard (GRS), and the OEKO-TEX® Standard 100.

Responsible Wool Standard (RWS)
Responsible Wool Standard is a certification owned by Textile Exchange. RWS is an international, but voluntary standard, with an aim to address animal welfare, specifically in  sheep farms. To attain this certification, each stage of the supply chain is verified by a  professional third-party body. Along with animals, the standard also makes sure progressive methods of land management are practised on the farms. The soil health, biodiversity and native species are protected.

The certification also ensures that the identity of the RMS mohair is maintained at all times

Global Recycled Standard (GRS)

Global Recycled Standard, owned by Textile Exchange, is a voluntary certification for the purpose of tracking and verifying the content of recycled materials in a final product. This  standard stands valid for the supply chainand addresses traceability, chemical content, as well as social and environmental practices. It covers processing, manufacturing, packaging, labelling, trading and distribution of all products made with a minimum of 20% recycled material.

This certification allows textile manufacturers to verify the recycled content of their products, and be responsible towards the environment, society and chemical practices. The goal of this standard is to encourage innovation in the use of recycled materials, to establish more transparency in the supply chain, and to provide better information to consumers. 

OEKO-TEX® Standard 100 

OEKO-TEX Standard 100 is a certification for textiles to verify that they have been tested for harmful substances and chemicals. It has a globally standardised test criterion, and complies with international requirements and regulations. OEKO-TEX categorises products into 4 classes. These classes start from Class I, which includes products for infants and toddlers, to Class IV, which includes products that have zero to minimal contact with the skin, such as upholstery materials 

  •  Class I: This class is specifically designed for products intended for babies and toddlers up to 36 months old. Infants, babies and toddlers are particularly sensitive to harmful substances. Examples of products in Class I include clothing, bedding, accessories, and toys for infants. This class of products have the most strict regulations to ensure the highest level of safety, as the matter concerns babies under 36 months
  • Class II: This class covers textile products that have direct contact with the skin, but for adults. It includes underwear, shirts, blouses, bedding, towels, socks, and other clothing articles. While the requirements are slightly less stringent than those of Class I, the products in this class still undergo thorough testing to ensure their safety for extended skin contact.
  • Class III: Textile products that do not have direct contact with the skin fall into Class III. This class includes items such as jackets, coats, outerwear, and other accessories. While these products may not have prolonged contact with the skin, they still undergo testing to ensure that any potentially harmful substances are within acceptable limits.
  • Class IV: This class is dedicated to textile products with minimal or no contact with the skin. It includes curtains, table linen, upholstery fabrics, carpets and so on. The requirements for Class IV are less stringent compared to the previous classes, considering the limited contact with the body.

How These Certifications Work Together

Why Certifications Matter More Than Ever

The regulations and concerns around the concept of sustainability are way more than they ever were. There is also a shift in consumer perspective, and everyone wants to be consuming materials that are not fast fashion and are environmentally responsible. In such a case, to help brands and manufacturers establish their validity and relevance, these certifications help brands and manufacturers:

  • Demonstrate verified sustainability practices
  • Meet international compliance requirements
  • Build long-term trust with buyers and consumers
  • Support ethical, safe, and environmentally responsible production
