Understanding Textile Exchange’s New Certification Framework

Preparing for the Materials Matter Transition

GRS CCS RAF

Is your organization ready for Materials Matter?

Textile Exchange is introducing a new certification framework that will progressively replace GRS, RCS, RWS, RMS and RAS.

For brands, manufacturers, traders, recyclers and raw material producers, the transition may affect certification, traceability, supplier engagement, sustainability claims and product labelling.

Understanding the changes today can help your organization prepare for tomorrow.

Why this matters

Materials Matter is more than a certification transition. It introduces a new approach to traceability, claims substantiation and supply chain transparency that may affect organizations across the entire value chain. The transition may impact >>

  • Product claims

  • Product labels

  • Supplier requirements

  • Traceability systems

  • Human rights expectations

  • Sustainability communications

  • Certification planning

What is Materials Matter?

Materials Matter is Textile Exchange’s new sustainability certification framework for raw material production and primary processing.

The framework brings together several existing standards into a more harmonised system designed to strengthen:

  • Human rights and livelihoods
  • Environmental management
  • Animal welfare
  • Traceability
  • Data integrity
  • Sustainability claims

The objective is to simplify the certification architecture while increasing transparency and credibility across supply chains.

Which standards are affected?

The following standards will transition into Materials Matter:

The following standards remain separate:

  • Organic Content Standard (OCS)
  • Responsible Down Standard (RDS)

For these Standards are remaining no-changed Standards.

Please ask us any further details.

For RCS

RCS-certified materials are not eligible inputs for Materials Matter certified products. Organizations currently relying on RCS should begin reviewing inventory, sourcing strategies and future certification plans.

Why is Textile Exchange introducing Materials Matter?

As expectations around supply chain transparency, sustainability claims and traceability continue to increase, Textile Exchange is evolving its standards system to provide a more consistent framework across different materials.

Materials Matter aims to:

  • Reduce complexity
  • Strengthen sustainability requirements
  • Improve traceability
  • Increase confidence in claims
  • Support better supply chain visibility

The transition is closely linked to Textile Exchange’s Climate+ strategy and reflects growing expectations around responsible sourcing, transparency and data integrity.
