The difference: both verify recycled content through a tracked chain of custody, but GRS (Global Recycled Standard) adds social, environmental, and chemical criteria and requires ≥50% recycled content for the main GRS logo, while RCS (Recycled Claim Standard) only verifies the recycled content itself, from 5% upward. GRS is the stronger, more comprehensive standard; RCS is the lighter content-only verification. Both are managed by Textile Exchange.
For B2B buyers making recycled claims, choosing between them is a question of how much you need to certify — just the recycled fiber, or the full responsible-production story. As a factory sourcing recycled polyester and nylon, here’s the distinction that matters in a brief.
GRS vs RCS in One Sentence
RCS certifies recycled content and its chain of custody; GRS certifies the same plus social responsibility, environmental practices, and chemical restrictions — making GRS the fuller sustainability claim.
RCS (Recycled Claim Standard)
A content-only standard. RCS verifies the presence and amount of recycled material through the supply chain via Transaction Certificates.
- ✅ Confirms recycled content (from 5%)
- ✅ Tracks chain of custody
- ✅ Simpler, lower barrier
- ❌ No social or environmental criteria
- Two labels: RCS Blended (5–95%) and RCS 100 (≥95%)
GRS (Global Recycled Standard)
A comprehensive standard built on RCS’s content tracking plus added requirements:
- ✅ Recycled content (≥20% to certify, ≥50% for the GRS product logo)
- ✅ Chain of custody (Transaction Certificates)
- ✅ Social criteria — labor/working conditions
- ✅ Environmental criteria — wastewater, emissions
- ✅ Chemical restrictions — restricted substances list
- ❌ More demanding, higher cost to certify
Side-by-Side Comparison
| Criterion | RCS | GRS |
|---|---|---|
| Recycled content verified | Yes (≥5%) | Yes (≥20%, logo ≥50%) |
| Chain of custody | Yes | Yes |
| Social responsibility | No | Yes |
| Environmental criteria | No | Yes |
| Chemical restrictions | No | Yes |
| Claim strength | Content only | Full responsibility |
| Manager | Textile Exchange | Textile Exchange |
Which Should You Require?
| If you need… | Require… |
|---|---|
| A simple “made with recycled X” claim | RCS |
| A full sustainability/ESG-grade claim | GRS |
| Retailer ESG compliance | GRS |
| Entry-level recycled marketing | RCS |
| Recycled + responsible production story | GRS |
Most serious EU/US sustainability programs require GRS because retailers and ESG frameworks want the social and environmental layer, not just recycled content. RCS suits lighter, content-focused marketing claims. Pair either with chemical-management standards and, for down, RDS.
How It Works in Production
For a finished jacket to carry GRS or RCS:
- The recycled fabric supplier must be certified
- Your manufacturing factory must hold scope certification
- Transaction Certificates document certified material at each step
- The brand applies the logo with valid backing
As with all chain-of-custody standards, an uncertified link breaks the claim — certified recycled fabric sewn in a non-certified factory loses the logo.
Specifying as a B2B Buyer
Require: the standard (GRS or RCS), minimum recycled %, valid Transaction Certificates, and confirmation the factory holds scope certification. State the recycled content target explicitly (e.g., “GRS-certified, ≥50% recycled polyester”) — a vague “recycled” claim without a standard and percentage is a greenwashing risk in the EU.
Frequently Asked Questions
What’s the difference between GRS and RCS certification?
RCS (Recycled Claim Standard) verifies only the recycled content and its chain of custody, from 5% upward. GRS (Global Recycled Standard) verifies recycled content plus social, environmental, and chemical criteria, and requires higher recycled percentages. GRS is the more comprehensive, retailer-preferred standard.
How much recycled content does GRS require?
GRS requires at least 20% recycled content for a product to be certified, and at least 50% to carry the GRS product logo. RCS, by contrast, certifies recycled content from just 5%, with an RCS 100 label for products that are 95% or more recycled.
Which recycled standard do retailers prefer?
Most EU and US retailers with ESG requirements prefer GRS because it certifies responsible production — labor conditions, environmental practices, and chemical restrictions — not just recycled content. RCS is accepted for simpler content-only marketing claims.
Does PTOUTWEAR offer GRS or RCS recycled fabrics?
We hold no GRS or RCS scope certification, so a “GRS-certified garment” claim cannot come from us as the sewing factory. We can quote recycled polyester and nylon faces and, where the mill holds GRS or RCS for that lot, pass the mill’s certificate through to you with the SGS test report – the certificate stays in the mill’s name. Write your claim as recycled content of the fabric. Custom jackets start at a 30-piece MOQ with 1-piece sampling.
Build Verified Recycled Programs With Documentation
GRS vs RCS comes down to how much you need to certify — recycled content alone (RCS) or the full responsible-production story (GRS). At PTOUTWEAR we build custom jackets in recycled fabrics from a 30-piece MOQ with 1-piece sampling, and we are explicit about which certificates the mill holds and which we do not. Our certifications page lists what we hold and what we do not; ask us and we will find out whether the mill for your fabric can issue a GRS or RCS transaction certificate, and say so either way.
