RPET, Organic Cotton, GRS: How to Tell a Real Eco Claim From a Sticker
In October 2020, the Global Organic Textile Standard went looking for a rumour and found a crime. Fraudsters had been printing fake raw-cotton Transaction Certificates on Indian government templates, complete with QR codes that led to a cloned copy of the government’s own website. GOTS confirmed 20,000 metric tons of fake organic cotton. Eleven companies were banned and one certification body lost its contract. (GOTS published the whole thing themselves.)
Sit with that for a second. The document the entire industry tells you to demand — the Transaction Certificate — is the document that got forged. At scale. With a working QR code.
So when a factory sends you a nice PDF and a logo, you have learned almost nothing. What you need is a way to verify, not a folder to collect. This piece is that method: what each standard actually proves, what it quietly doesn’t, the two numbers that make most “GRS certified” claims non-compliant, and the fact that GRS itself is being retired — which almost nobody in the bag industry has noticed yet.
What does “GRS certified” actually mean on a bag?
It means a specific factory passed an audit — not that your bag contains recycled content. Those are two different claims, proved by two different documents, and mixing them up is where most brands get exposed.
- Scope Certificate (SC) — the facility’s licence. It proves the site is qualified to handle certified goods. It says nothing about your order.
- Transaction Certificate (TC) — a shipment-specific document issued by an independent certification body, not by the supplier, confirming that the exact quantity you bought moved through the certified chain.
A Scope Certificate confirms a factory is capable of producing certified goods. A Transaction Certificate is the only document that verifies your specific order met the standard. If a supplier hands you an SC and goes quiet when you ask for a TC, that is not an oversight. Issuing a TC costs them an audit fee and creates a record. Silence is the answer.
Then there are the two numbers.
GRS can be used as a business-to-business tool for products containing at least 20% recycled content, but consumer-facing labelling requires at least 50%. Product-specific labelling under GRS requires 50% or more recycled content. So a tote at 30% rPET can be legitimately certified — and printing “GRS certified” on the hangtag is still a claims violation. I have watched brands walk straight into this because their factory said “yes, it’s GRS” and nobody asked what percentage, and for which claim.
Why is the certificate on the shipment worth more than the one on the wall?
Because GRS runs on chain of custody: every company that takes ownership of the material must be certified, and one uncertified link voids the whole thing. Recycler → yarn spinner → fabric mill → dyer/finisher → bag manufacturer. Each stage must be certified for the finished bag to carry the claim. If the fabric supplier isn’t certified, the claim collapses — no matter how certified your bag factory is.
This is the sentence to remember when a bag factory shows you its own certificate: a certified cut-and-sew factory sewing uncertified fabric produces an uncertified bag. The sticker is on us; the truth is upstream.
The same logic runs through organic cotton, and it’s the reason for a rule change most buyers missed. Since 1 December 2022, Textile Exchange’s OCS stopped accepting GOTS inputs unless it receives full transaction-certificate data tracing back to the original farm — and any gin feeding GOTS material into an OCS product must itself be OCS certified. (Textile Exchange’s own account of why.) That policy exists because of the fraud in the first paragraph. Standards bodies stopped trusting each other’s paper. You probably shouldn’t be more trusting than they are.
If certificates can be forged, what actually counts as verification?
Verification means the certificate number checks out in the issuing body’s own records, the scope covers your material, and the dates cover your shipment. Anything less is filing, not checking.
Five things, in order. None takes more than an afternoon.
- Get the certificate number and the certification body — not the PDF. Control Union, SGS, Intertek, TÜV, Ecocert, IDFL. A PDF is an image. A number is a claim you can test.
- Look it up independently. The Textile Exchange certified company directory and the GOTS public database both let you check a certificate number against the issuing body’s own records. Search the legal entity name, not the trading name — this is where lookups quietly fail.
- Check the scope actually covers your product. A supplier can hold a real, current certificate that covers organic cotton and sell you recycled polyester under it. The certificate covering the wrong material is one of the most common real-world traps. Also check the site: certificates get borrowed from sister companies.
- Match the TC to your PO. Product description, quantity, factory identity, and dates on the TC must line up with your order and with the exact wording you plan to print. A TC that doesn’t reconcile with your PO is decoration.
- Sanity-check the price. Certified material and certified production cost more — audit fees, stricter process control, higher input costs. If the “GRS” bag is priced the same as the conventional one, be very skeptical. Certification is not free, and nobody absorbs it out of kindness.
If you only do one of these, do number two. The forged Indian TCs beat step one and died at step two.
What does each standard actually prove — and what does it quietly not?
Most disputes come from a standard being asked to prove something it was never designed to prove. Read this table as “what I can legitimately say,” not “which one is best.”
| Standard | What it proves | What it does NOT prove | Threshold |
|---|---|---|---|
| GRS (Global Recycled Standard) | Recycled content + chain of custody + social, environmental and chemical criteria at certified sites | That your specific shipment complied — that’s the TC’s job | 20% to certify; 50% for consumer-facing labelling |
| RCS (Recycled Claim Standard) | Recycled content and chain of custody, full stop | Nothing about labour, chemicals, or environment — it is a single-attribute standard | 5% minimum |
| OCS (Organic Content Standard) | That organic fibre wasn’t swapped for conventional along the chain | Nothing about dyes, chemicals, or working conditions — an OCS product can legitimately use conventional synthetic dyes | Content-based |
| GOTS | Organic fibre plus restricted chemistry and social criteria across processing | That the farm-level cotton is genuinely organic — GOTS is a processing standard that relies on national organic certification upstream, which is exactly where the 2020 fraud got in | 70% = “made with organic”; 95% = “organic” |
| OEKO-TEX Standard 100 | The finished article tested free of a list of harmful substances | Nothing about organic origin, recycled content, or sustainability | Product tested |
The row that surprises people is GOTS. It is the strictest standard here, and it was still the one the fraud walked into — because GOTS is a post-harvest processing standard that relied on government-supervised organic cotton certification at the farm. Strict downstream, dependent upstream. To be fair to GOTS: after the fraud, it began checking every incoming raw-material transaction certificate for authenticity itself, rather than trusting the government system it had relied on. That’s a real fix, and it’s more than most schemes have done. But the lesson generalises — every certification scheme has a seam where it stops verifying and starts trusting. Knowing where your standard’s seam is is the expertise.
Is your GRS certificate about to expire — permanently?
Yes. GRS and RCS are being retired into Textile Exchange’s new Materials Matter Standard, and the dates are already fixed. This is the part almost no bag supplier has told you, and it changes what “get GRS certified” is worth if you start today.
The Materials Matter Standard criteria were published on 12 December 2025. It becomes effective on 31 December 2026 and mandatory on 31 December 2027. Organizations may keep using the current standards until then. GRS and RCS — along with the responsible animal fibre standards — are being folded into MMS at Tier 4, while downstream chain of custody moves to the Content Claim Standard (CCS).
Two details from the transition policy that will land on your desk:
- Tier 1–3 organizations previously certified to GRS plus CCS transition to CCS only by 31 March 2029, at which point all valid GRS scope certificates are withdrawn. Your bag factory is Tier 1–3. Its GRS scope certificate has an end date now.
- RCS-certified materials may not be used as inputs into Materials Matter Certified products and must be kept segregated. If your fabric is RCS and your program is heading to MMS, that’s a sourcing problem, not a paperwork problem.
Organic cotton follows a separate, phased path — OCS keeps its traceability role for now.
What to actually do about it: don’t panic-recertify, and don’t let a factory sell you a shiny new GRS certificate as a long-term asset. Ask them one question — what’s your MMS transition plan and who’s your certification body for it? — and listen to whether there is a plan or a pause. Then check your artwork: hangtags, polybags, and packaging carrying GRS logos will need a relabelling runway before the mandatory date, and that runway is production lead times long, not marketing-email long.
Meanwhile in the EU, the Empowering Consumers Directive starts applying on 27 September 2026, tightening the rules against vague environmental claims made without evidence. Two deadlines, one direction: the era of “eco-friendly” as a free adjective is closing.
Does RPET actually make your bag sustainable?
It makes one input better. It does not make a bag sustainable — and a factory that lets you believe otherwise is selling you a sticker.
Here’s the uncomfortable arithmetic, from someone who cuts and sews this stuff. Recycled polyester is still polyester: it still sheds microfibres, it is still difficult to recycle again once it’s been laminated, dyed and stitched into a bag with metal hardware. A 100% rPET tote that splits at the handle after eight months and goes to landfill is not a win, whatever the hangtag says.
The single biggest environmental variable in a bag is not the fibre. It’s how many years the bag stays out of the bin. And that variable — unlike the fibre story — is measurable without any certificate at all: seam strength, load-bearing, zipper cycles, colourfastness after real washing.
That’s not an argument against RPET or organic cotton. Use them; the input matters. It’s an argument against buying them instead of durability, which is what a lot of “sustainable” bag programs quietly do — a thinner recycled canvas at the same price, because the certificate had to be paid for somewhere. Ask your factory what the GSM was before and after the eco switch. The answer tells you what got traded.
If you want to see what durability evidence looks like when it isn’t a slogan, our quality-control and testing standards are the version we’d want a buyer to check us against — load, drop, zipper-cycle and colourfastness numbers, not adjectives.
Six questions to ask before you print a logo on the hangtag
Send these in one email. The reply — and the speed of it — tells you more than any brochure. (If you’re earlier in the process and still mapping out how materials, sampling and QC fit together, start with the bag manufacturing process first — claims sit on top of a supply chain, not instead of one.)
- “What’s your Scope Certificate number, which certification body, and what’s the valid-through date?” Then look it up yourself. Don’t accept the PDF as the answer.
- “Does that scope cover this material and this site?” Recycled polyester, organic cotton and the specific factory address — all three, explicitly.
- “Will you issue a Transaction Certificate for my order, and when?” “We have GRS, you don’t need a TC” is a red flag every time.
- “Is my fabric mill certified too — and its supplier?” The chain, not the last link.
- “What exact recycled percentage, and what claim am I therefore allowed to print?” Get the number, then check it against the 50% threshold before artwork goes to print.
- “What’s your Materials Matter transition plan?” In 2026 this is the question that separates a factory that reads its standards from a factory that frames them.
If a supplier can’t answer 1–3 within a week, you don’t have a compliance risk yet. You have a supplier risk. Same logic as vetting a Chinese bag factory before you pay a deposit — the paperwork test is really a character test.
FAQ
Can I say “made with recycled materials” without any certification?
You can say it, and increasingly you’d better be able to prove it. Certification isn’t legally mandatory — substantiation effectively is, especially in the EU from late 2026. An uncertified claim is a claim with no evidence behind it.
Is GRS better than RCS?
Different, not just better. RCS verifies recycled content and nothing else; GRS adds social, environmental and chemical criteria and a higher content threshold. If all you need is a content claim, RCS is cheaper and faster.
My factory is GRS certified. Isn’t that enough?
No. If your fabric mill isn’t certified, the chain is broken and your finished bag isn’t certified — regardless of your factory’s certificate.
Should I bother getting certified for a 500-piece first run?
Often not. Certification costs and audit lead times don’t scale down well. Better to make an honest, specific, uncertified claim (“contains recycled polyester”) than an unverifiable certified-sounding one.
Is organic cotton canvas worth the premium for bags?
Sometimes. Expect roughly a 20–40% premium over conventional. If your buyer audits claims, yes. If you’re selling on durability and price, spend the money on fabric weight and reinforcement instead — that’s a judgement call, and reasonable people disagree.
