Key Takeaway
Textile, apparel, home textile, footwear, and bag companies currently using Textile Exchange system standards such as GRS, RCS, and RWS need to focus today not just on when current certificates need renewal, but on the transition arrangements for the Materials Matter Standard.
According to Textile Exchange's official public information, the Materials Matter Standard will take effect on December 31, 2026, and will become a mandatory transition requirement by December 31, 2027. The first edition covers recycled materials and animal fibers. For sellers, this is not just a reminder that standards will update in the future — it means supply chain documentation, transaction certificates, label declarations, and customer-facing page language all need to be organized in advance.
Why You Cannot Wait Until Certificate Renewal
Standards like GRS, RCS, and RWS are typically not single-certificate issues. A finished product page claiming recycled materials, responsible wool, or traceable sourcing usually involves scope certificates, transaction certificates, supplier entities, material ratios, product scope, and label usage boundaries.
If you wait until a certificate expires to act, three common risks arise:
1. The supplier certificate holder does not match the current procurement entity;
2. Finished product SKU material batches lack corresponding transaction certificates or records;
3. Customer-facing pages expand material declarations into claims about the entire product, brand, or carbon neutrality.
Three Types of Clients: What to Do First
1. Clients Working with Recycled Materials
First build a table by SKU for GRS and RCS-related products: material type, recycled content, supplier, scope certificate, transaction certificate, label/hang tag usage. Page language should only express what can be covered by documentation — do not write recycled material content as low-carbon product or full-chain sustainable.
2. Clients Working with Wool and Animal Fibers
First verify RWS or related animal fiber evidence: farm, supply chain entity, scope certificate, transaction documents, finished product scope. External communications should focus on animal welfare and land management boundaries, avoiding generalization to all environmental claims.
3. Clients Using OEKO-TEX, FSC, GOTS Simultaneously
Separate the uses of each standard. OEKO-TEX STANDARD 100 primarily supports textile harmful substance testing declarations; FSC supports forest-sourced material declarations; GOTS supports organic textile chain declarations. They can supplement the evidence chain but cannot automatically replace GRS, RCS, RWS, or Materials Matter transition preparation.
A Transition Preparation Table
Column 1: Existing Claims. List every recycled, wool, responsible sourcing, harmful-substance-free, FSC, and organic term appearing on detail pages, official websites, short videos, and customer service scripts.
Column 2: Corresponding Standard. Mark GRS, RCS, RWS, OEKO-TEX, FSC, GOTS, OCS, or other evidence sources.
Column 3: Evidence Documents. List scope certificates, transaction certificates, test reports, verification screenshots, supplier declarations, procurement documents, and SKU cross-reference tables.
Column 4: Transition Actions. Mark whether you need to request supplementary documents from suppliers, adjust page language, prepare renewal materials, or re-evaluate your certification pathway.
