Materials Matter Standard (MMS): Textile Exchange's new standard for textiles. What are the changes?

Textile Exchange is radically changing its certification system with the Materials Matter Standard (MMS), a unique standard dedicated to the production and processing of materials. The final criteria, published on December 12, 2025, mark the start of a transition phase that will gradually replace several existing Textile Exchange standards.

As a certification body that has been working alongside textile players for many years, Ecocert is now supporting its clients in preparing for this strategic transition.

• What is Textile Exchange's Materials Matter Standard (MMS)?

The Materials Matter Standard (MMS) is Textile Exchange's new unified standard for regulating the production and processing of materials in the textile and fashion industries.

It aims to:

📌 Bring together, within a coherent framework, several existing standards (GRS, RCS, certain standards from the Responsible Animal Fiber: RAS, RMS, RWS). 📌 Structure requirements around clear impact objectives on climate, nature, people, and animal welfare. 📌 Facilitate the management and steering of commitments through a single reference framework rather than a multiple portfolio of standards.

The MMS Standard is primarily aimed at material producers (farmers, ranchers, fiber producers, recyclers). It aims to ensure that practices at these key stages of the supply chain contribute to measurable sustainability outcomes.

• Why is Textile Exchange launching a new single standard?

The proliferation of textile standards and labels has helped to advance practices, but can also complicate the situation for companies, with:

📌 Difficulty navigating between standards. 📌 Certification portfolios that are cumbersome to manage across multiple sites and materials. 📌 Difficulty on transparent framework for organizations and brands to substantiate their material claims

With the MMS standard, Textile Exchange seeks to:

📌 Simplify the standards landscape for producers, processors, and brands with a single, more transparent framework. 📌 More clearly link certification requirements to scientific objectives and measurable outcomes (greenhouse gas emissions, soil, biodiversity, working conditions, animal welfare, etc.). 📌 Enhance the overall effectiveness of the system by pooling data collection, traceability, and verification efforts. 📌 For companies already committed to Textile Exchange standards, this convergence is an opportunity to streamline their approaches, provided they anticipate the transition.

• What is the timeline for transitioning to the Materials Matter Standard (MMS)?

Textile Exchange is planning a multi-year transition period to prepare for the move to MMS.

🗓️ December 12, 2025: Publication of the final MMS criteria and the associated claims and labeling policy

🗓️ December 31, 2026: Opportunity for relevant and eligible companies to become certified under the new MMS standard.

🗓️ December 31, 2027: New MMS standard mandatorily comes into effect for eligible farm production & first processing companies, with a scheduled phase-out of the old Textile Exchange standards

At the end of the period defined by Textile Exchange, the MMS will become the sole framework, and the old standards will no longer be used.

Ecocert recommends beginning this transition in advance, to roll it out gradually, smoothly, and in line with production cycles and commercial constraints.

• What changes will there be for players in the value chain?

For all players in the value chain (producers, recyclers, processors, brands, and distributors), the MMS standard provides a common reference framework that harmonizes environmental, social, traceability, and document management requirements, simplifies audits, and enhances consistency between operational practices, brand expectations, and regulatory obligations.

• How does the MMS standard strengthen the credibility of product claims and labels?

The MMS is accompanied by a policy dedicated to claims and labeling, aimed at reducing the risk of greenwashing and ensuring consistency between:

📌 The practices implemented (agricultural practices, social conditions, input management, recycling, etc.). 📌 The messages communicated on products, in marketing campaigns, or in sustainability reports.

The Materials Matter Standard contributes to:

📌 Clarifying the conditions of use of logos, statements, and labels related to the standard. 📌 Strengthening traceability requirements throughout the supply chain to link claims to verifiable data. 📌 Supporting companies in meeting the growing expectations of consumers and regulators in terms of transparency.

• How is Ecocert supporting the transition to the Materials Matter Standard (MMS)?

This quest for consistency is part of Ecocert's approach, which helps organizations ensure the reliability of their labels and communications in the context of evolving regulatory frameworks on environmental claims.
