Standards we meet

The CHT Group must meet further requirements besides legal regulations.

Our customers and we as a result must face an increased number of standards for the textile industry issued by reputable certification bodies and also company standards of different brands, retailers and of the trade.

The most widespread standards of independent organisations besides company standards:

  • bluesign®
  • Global Organic Textile Standard (GOTS)
  • Cradle-to-Cradle® (EPEA)
  • EU Umweltzeichen


The dedication and the responsibility of CHT are illustrated by the fact that we have decided to become a bluesign supporter in 2008.
Our decision was based on the comprehensive assessment of risks and hazards by the bluesign overall concept. This concept deals with chemical products and substances used by the company and also the process of managing air, water, soil, people and energy.


In 2011, a group of major apparel, leather, and footwear brands and retailers made a shared commitment to reduce or substitute hazardous chemicals from their value chain to ensure a safer handling of chemicals. This was the origin of the ZDHC Initiative.

Meanwhile the ZDHC Initiative has transformed to the Stichting ZDHC Foundation© based in Amsterdam. During that time the number of ZDHC Contributors has increased to almost 150 composed of 29 Signatory Brands and Retailer, 101 Value Chain Affiliates (chemical suppliers, textile and footwear manufacturers as well as service providers) and additionally 18 organizational associates (industry associations, NGOs and institutional partners such as government or academia). Therefore, the ZDHC Foundation represents the whole supply chains of the textile and leather industry as well as associated and interested groups of these industries and the public community.

CHT Group continues to take a leading role within chemical manufacturers for the textile supply chain. In this spirit CHT Group was one of the driving forces when a group of almost 10 internationally well-known chemical manufacturers decided to become ZDHC Contributor in summer 2019.

The ZDHC Contributors jointly develop and implement methods and tools for safer chemicals management, for the reduced consumption of resources and the environment, and for the protection of mankind and nature. The CHT Group contributes in several ZDHC Task Teams and is a member of the ZDHC internal Chemical Industry Advisory Group (CIAG). The CHT Group also demonstrates its capabilities with over 1800 products uploaded to the Chemical Module of the ZDHC Gateway. Almost 90% of these products have Level 3, the highest conformance level in the ZDHC Gateway. This makes the CHT Group the leader in the data exchange platform for demonstrating the conformity of chemical products regarding the ZDHC MRSL, another important tool of the ZDHC Foundation.
