What Is the Global Recycled Standard (GRS)?
GRS (Global Recycled Standard) is an international, voluntary, full product standard that sets third-party certification requirements for recycled content, chain of custody, social and environmental practices, and chemical restrictions. It is owned and managed by Textile Exchange, a global non-profit organization. Although best known in textiles, the standard also applies to plastics, metals, paper, and glass — any product containing recycled material. The standard uses the ISO 14021 definition of recycled content, with interpretations aligned to the U.S. Federal Trade Commission (FTC) Green Guides.
GRS was originally launched in 2008 by Control Union Certifications, and its ownership was transferred to Textile Exchange (then Organic Exchange) on 1 January 2011. The current version, GRS 4.0, has been in effect since 1 July 2017. Today, more than 90,000 sites worldwide are certified to one of Textile Exchange's programs, including GRS and the Responsible Wool Standard, which underlines how widely the standard is recognized by brands and retailers.
Why GRS Matters in 2026
For manufacturers and exporters, GRS certification is rarely optional when a major brand is the customer. The most common drivers are:
Market access. Global brands require GRS from suppliers before they will source recycled-content products.
Verified recycled claims. The chain-of-custody system gives buyers independent proof of recycled content from input to finished product.
Product differentiation. Only products with at least 50% recycled content may carry the product-specific GRS label, supporting premium positioning.
Regulatory alignment. Recycled-content claims must meet legal requirements in each market of sale; GRS helps demonstrate compliance.
GRS 4.0 Requirements at a Glance
GRS certification is built on five interconnected requirement areas, all verified during the certification audit. Understanding them early saves the most time during preparation.
1. Recycled Content
A product must contain at least 20% recycled material to be certified to the GRS. Recycled material includes pre-consumer material (manufacturing waste diverted from the waste stream) and post-consumer material (material from households or commercial, industrial, and institutional end-users that can no longer be used for its intended purpose). Every recycled input entering the supply chain must be covered by a valid Transaction Certificate (TC) issued by an approved certification body.
2. Chain of Custody (Content Claim Standard)
Material is tracked from input to finished product under Textile Exchange's Content Claim Standard (CCS). Certified sites must keep GRS and non-GRS materials clearly identifiable and separated — by space or by time — so recycled content can be traced at every stage. Traceability must be assured one step back and one step forward at each supply-chain stage, and a mass-balance calculation supports the recycled percentage claimed.
3. Social Requirements
Based on International Labour Organization (ILO) labour standards, the social module prohibits forced and child labour, protects freedom of association, bans discrimination and abuse, and sets requirements for wages, working hours, and health and safety. The most stringent of national law, local law, or the GRS requirement applies.
4. Environmental Requirements
Certified sites must operate an Environmental Management System (EMS) and a Chemical Management System (CMS). The standard covers energy use, water use, wastewater and effluent treatment, air emissions, and waste management, with tracked indicators and improvement targets.
5. Chemical Requirements
The GRS restricts hazardous chemicals in the production of GRS products. Chemical formulations must comply with the ZDHC Manufacturer's Restricted Substance List (MRSL) and exclude substances of very high concern under REACH. Each chemical input requires an up-to-date Safety Data Sheet (SDS) available to workers and in English.
GRS Certification Levels and Label Rules
GRS distinguishes between certification (which proves a site can make GRS product) and labelling (which lets a product carry the GRS logo). The threshold determines what you may claim:
| Recycled Content | Can Be Certified? | May Use GRS Product Label? |
|---|---|---|
| Below 20% | No | No |
| 20% – 49% | Yes | No (B2B claims only) |
| 50% – 100% | Yes | Yes — "Made with X% Recycled Material" |
GRS Certification Process: Step by Step
Certification follows Textile Exchange's accreditation and certification procedures, applied by independent third-party certification bodies accredited to ISO 17065. The sequence below reflects the standard workflow used by approved certification bodies such as SGS, Intertek, Control Union, Bureau Veritas, TÜV, IDFL, and SCS Global.
Step 1: Define Scope and Submit Application
Identify which products, production lines, and sites will be covered. Confirm your product meets the 20% recycled-content threshold and gather basic documents — business license, process flow chart, and any existing recycled-material supplier certificates. Submit the application to an approved certification body (CB).
Step 2: Conduct Gap Analysis and Build Your System
Compare current practices against the GRS requirements. Build the required management system: a recycled-material traceability ledger, chemical inventory and SDS files, environmental records (wastewater, energy, waste), social documentation (working hours, wages, HR records), and a mass-balance calculation for recycled content. Keep GRS and non-GRS materials clearly separated to prevent mix-ups.
Step 3: Sign Contract and Confirm Quotation
The certification body reviews your application and issues a proposal with the audit scope and fees. After you sign the agreement and complete payment, the audit is scheduled. Costs vary by certification body, the number and type of sites, and audit duration, so request a written quotation before committing.
Step 4: Document Review
The auditor examines your system files — GRS manual, traceability procedures, chemical list, environmental and labour records, and recycled-content calculations. Any gaps are raised as findings to correct before the on-site visit.
Step 5: On-Site Audit
The auditor visits the site to verify practice against documentation: material identification and segregation, batch records, TC coverage of inputs, chemical storage and SDS, wastewater treatment, and worker interviews. The audit typically spans one or more days on site depending on facility size and scope.
Step 6: Certification Decision and Scope Certificate Issuance
If the audit finds the site compliant (or non-conformities are closed with evidence), the certification body issues the Scope Certificate. Your site is now authorized to produce and sell GRS-certified products.
Ongoing: Transaction Certificates and Annual Surveillance
After certification, apply for a Transaction Certificate for each shipment, using the upstream TCs to calculate the recycled percentage. A Scope Certificate must exist before any Transaction Certificate can be issued. Certification is maintained through an annual surveillance audit. Traders with an annual turnover below USD 10,000 of GRS products are exempt from certification, provided they do not repack or relabel GRS products.
How Long Does GRS Certification Take?
The timeline depends on how ready your system is and on certification-body scheduling. A typical first certification runs from a few weeks to a few months: application and quotation, document review (roughly one to two weeks), on-site audit (commonly one or more days on site), and correction plus certificate issuance (roughly one to two weeks). Sites with a mature management system and complete records move through the process fastest.
How Much Does GRS Certification Cost?
GRS certification fees are set by each certification body and are not fixed by Textile Exchange. They typically include an initial audit fee, a certificate fee, and an annual surveillance audit fee (often a fraction of the initial audit). Total cost scales with the number of sites, the processes involved, and audit duration. The most reliable way to budget is to request a written quotation from your chosen certification body after defining scope. Avoid any single fixed price quoted online, as fees legitimately differ by certifier and by the complexity of your operation.
GRS 4.0 and the Materials Matter Standard (MMS) Transition
In December 2025, Textile Exchange published the final criteria for the Materials Matter Standard (MMS) — a unified framework that will consolidate the Global Recycled Standard (GRS) and Recycled Claim Standard (RCS) together with Textile Exchange's Responsible Animal Fiber standards (RWS, RAS, RMS). Organic cotton (OCS) follows a gradual transition pathway into the Materials Matter System.
The key dates for your 2026 planning are:
| Date | Milestone |
|---|---|
| 12 Dec 2025 | MMS final criteria published |
| 31 Dec 2026 | MMS becomes effective (sites may start to get certified to MMS) |
| 31 Dec 2027 | MMS mandatory (GRS and related standards consolidate into MMS) |
For 2026, the practical message is simple: GRS 4.0 remains fully valid and is still the active standard you should certify to today. GRS and MMS run in parallel from late 2026, and GRS certificates issued now remain useful through the transition. Getting certified now secures brand-access requirements and gives you lead time before any migration to MMS. Plan renewal and new-certification decisions with the 2027 mandatory date in view, but do not delay market access waiting for MMS.
GRS vs RCS vs GOTS: Which Recycled or Responsible Standard?
| Standard | Owner | Minimum Recycled / Organic | Social / Environmental / Chemical |
|---|---|---|---|
| GRS | Textile Exchange | 20% recycled | Yes (full) |
| RCS | Textile Exchange | 5% recycled | Chain of custody only |
| GOTS | Global Standard | 70% (label) / 95% (organic) | Yes (organic focus) |
Choose GRS when you need full responsible-production verification (recycled content plus social, environmental, and chemical requirements) and a product label at 50%+. Choose RCS to prove recycled content alone at a lower 5% threshold. Choose GOTS for organic-fibre products rather than recycled content.
FAQ: GRS Certification Frequently Asked Questions
The following questions are the ones manufacturers ask most often when planning GRS certification.
Q: What is GRS certification?
A: GRS (Global Recycled Standard) is a voluntary, full product standard owned by Textile Exchange. It verifies recycled content, chain of custody, social and environmental practices, and chemical restrictions through independent third-party certification.
Q: What is the minimum recycled content for GRS?
A: A product must contain at least 20% recycled content to be certified to the GRS. Only products with at least 50% recycled content qualify for the product-specific GRS label.
Q: How long is a GRS certificate valid?
A: A Scope Certificate is typically valid for 12 months. Certification is maintained through an annual surveillance audit, and the certificate must be renewed before expiry to avoid a gap in coverage.
Q: What is the difference between a Scope Certificate and a Transaction Certificate?
A: A Scope Certificate (SC) certifies your site or organization and authorizes it to produce and sell GRS-certified products. A Transaction Certificate (TC) is issued for each specific shipment, proving that batch follows the GRS standard from material to finished product. A Scope Certificate must exist before any Transaction Certificate can be issued.
Q: What is the difference between GRS and RCS?
A: Both are owned by Textile Exchange. The Recycled Claim Standard (RCS) verifies recycled content only, with a 5% minimum. The GRS adds social, environmental, and chemical requirements on top of recycled content and chain of custody, with a 20% minimum. Choose RCS to prove recycled content alone; choose GRS for full responsible-production verification.
Q: Is GRS certification mandatory?
A: The GRS is a voluntary standard, but it is effectively required by many global brands as a condition of supply. Small traders with under USD 10,000 annual GRS turnover are exempt if they do not repack or relabel GRS products.
Q: Can I get GRS certified without recycled materials?
A: No. The standard applies only to products containing at least 20% recycled material. A site handling no recycled input cannot be certified to the GRS, though it may still need to manage GRS material passing through under chain-of-custody rules.
Q: What is happening with the Materials Matter Standard (MMS) in 2026 and 2027?
A: Textile Exchange published the MMS final criteria in December 2025. MMS becomes effective on 31 December 2026 and mandatory on 31 December 2027, consolidating GRS, RCS, and the Responsible Animal Fiber standards. GRS 4.0 remains valid through 2026 and the parallel period, so you should still certify to GRS now to meet current brand requirements.
Conclusion
GRS certification is a structured, verifiable pathway that opens doors to global recycled-material supply chains. With a clear understanding of the 20% recycled-content threshold, the five requirement areas, and the application-to-surveillance process, most facilities can plan certification confidently — and GRS 4.0 remains the standard to certify to in 2026.
