GRS
TEXTILES
CONFIDENCE MEDIUM · ANALYSIS ONLY, NOT AN AUDIT OR CERTIFICATION
Our read
GRS is the stronger of Textile Exchange's two recycled marks because it does not stop at content. Every certified site also has to pass social criteria drawn from the Global Social Compliance Programme code and ILO conventions, an environmental management and wastewater requirement, and a chemical input restriction referencing the ZDHC MRSL, all checked in an annual on-site audit. That is what separates GRS from RCS, and it is the reason a GRS hang tag carries more information than an RCS one. Two limits matter. The certification threshold is 20% recycled content while the consumer label needs 50%, so a supplier can accurately describe a product as GRS certified when it is mostly virgin material. And the content claim itself is a documentary one: transaction certificates, declaration forms and a mass balance reconciliation, with no test on the finished article. The waste stream origin is the weakest link, since collection and sorting sites are self-declared rather than certified. GRS also says nothing about the non-recycled remainder of the blend.
What it covers
- recycled content of 20% or more as the threshold for a product to be certified, with only pre-consumer and post-consumer material counting toward the figure
- a 50% recycled content floor before a product may carry the GRS mark in a product-specific consumer-facing claim
- chain of custody at every stage from the recycling stage to the last seller in the final business-to-business transaction, operated through the Content Claim Standard, with Scope Certificates and Transaction Certificates for every shipment
- pre-consumer and post-consumer percentages recorded separately per batch at each certified site and carried on the transaction certificate
- social requirements at every certified processing site, based on the Global Social Compliance Programme reference code and ILO conventions, covering forced labour, child labour, discrimination, freedom of association, wages, working hours, health and safety
- environmental requirements at every certified processing site: an environmental management system, monthly energy and water metering, annual improvement targets, wastewater treatment against Appendix D limit values with test reports no older than six months
- chemical requirements on inputs used in processing: chemical management system, safety data sheets, restricted substance list, hazard-class exclusions, and recorded assessment against the ZDHC Manufacturing Restricted Substances List
- annual on-site audit by a Textile Exchange approved certification body, with IOAS available as the accreditation body for Textile Exchange programmes
What it leaves out
Not a criticism of the scheme. A standard is a scope, and this is where this one ends.
- blending is permitted and the certified percentage is a proportion by mass of recycled material in the product, so a GRS certified product can be as little as 20% recycled; the GRS consumer label requires 50%, which means a product legitimately described as GRS certified in trade documents may be four-fifths virgin material
- the recycled content is established by documents rather than by measurement: transaction certificates, declaration forms, a mass balance formula reconciling inputs to outputs and a visual check that incoming shipments are not virgin; the standard sets no analytical or tracer test of recycled content in the finished article
- the origin of the waste stream is not certified; Material Collection and Material Concentration sites are subject only to self-declaration, document collection and on-site visits, and the supplier agreement grants the certification body a visit on three days' notice limited to confirming legal status and pre- or post-consumer designation
- no criteria on the non-recycled remainder of a blended product, so at the 20% floor up to 80% of the fibre is outside the standard entirely, with no organic, land-use or fibre-origin requirement
- no requirement that recycling be textile-to-textile; any reclaimed pre- or post-consumer material meeting the definition qualifies, including PET bottle feedstock diverted from another recycling stream
- chemical restrictions cover inputs used in processing only; the standard states it does not address the chemicals present in the reclaimed materials or what may be present in final GRS products
- no product quality, durability, microfibre shedding or legal compliance criteria; the standard states plainly that it does not address quality or legal compliance
- environmental criteria are management-system and improvement-target requirements, not absolute performance thresholds, and there is no greenhouse gas accounting or emissions reduction requirement
- traders with under USD 10,000 annual turnover of GRS products, and retailers selling only to end consumers, are exempt from certification provided they do not repack or relabel

What we read
Global Recycled Standard 4.0, original release date 1 July 2017, effective 1 July 2017 (replaces GRS 3.0)
- what_it_covers, what_it_omits (20% certification floor) — The Standard applies to products that contain 20% or more Recycled Content.
- what_it_covers, what_it_omits (50% floor for product labelling) — Only products with at least 50% Recycled Content qualify for product-specific GRS labeling.
- what_it_covers (chain of custody span and uncertified collection sites) — Each stage of production is required to be certified, beginning at the recycling stage and ending at the last seller in the final business-to-business transaction. Material Collection and Material Concentration sites are subject to self-dec
- what_it_covers (social and environmental criteria in processing) — The Standard establishes criteria for social and environmental principles in processing GRS certified products.
- what_it_omits (chemicals in reclaimed material and final product not addressed) — The Standard restricts the use of hazardous chemicals in the processing of GRS products; it does not address the chemicals present in the Reclaimed Materials or what may be present in final GRS products.
- what_it_omits (no quality or legal compliance scope) — The GRS does not address quality or legal compliance.
- what_it_omits (percentage is by mass; documentary basis and mass balance formula) — Recycled Content: Proportion, by mass, of Recycled Material in products or packaging. ... Certified Organizations shall address this through their mass balance formula for each material
- what_it_omits (visual inspection of incoming material rather than testing) — Inspect all incoming shipments of Reclaimed Material to confirm that they are not virgin material; confirm the correct identification as Pre- or Post-Consumer.
- what_it_omits (three days notice, limited scope of collection-site visit) — we give permission to [Certification Body] to visit our facility with a minimum notice of 3 days. The inspection will relate only to verification of our status as a legal organization and to confirm the description of materials as Recycled

What we could not establish
GRS 4.0 dated 1 July 2017 is the version served by Textile Exchange and is the version read in full. The standard itself states the next scheduled revision was 2021; I could not confirm whether a later version or a consolidated Textile Exchange standard has since superseded it, because textileexchange.org returns HTTP 403 on its standards pages to this fetcher and the search budget was exhausted. Treat the version field as the document read, not as a verified statement of what is current. The Content Claim Standard, which carries the detailed chain-of-custody mechanics that GRS incorporates by reference, could not be retrieved at any URL tried; the chain-of-custody description here therefore rests on what the GRS text itself states, and the precise segregation-versus-mass-balance mechanics of the CCS are not established. GRS references a mass balance formula only for reconciling differential production loss between recycled and virgin inputs, which is not the same as a mass balance chain-of-custody model, and I have not asserted either way. Independence is scored 4 on the basis that certification is by a Textile Exchange approved third-party body under an annual on-site audit and that IOAS operates accreditation for Textile Exchange programmes; the Accreditation and Certification Procedures document was not readable, so mandatory ISO/IEC 17065 accreditation is not confirmed. Enforcement is scored 3 on the basis of an annual audit and a published integrity contact route; no register of suspended or withdrawn GRS certificates was located.
If you hold this certification, it is already on your record. What a buyer cannot see there yet is the evidence behind the parts this standard does not reach.
