GRS, FSC, rPET and Natural Rubber: How to Verify Sustainable Pet Product Claims

Ask for the certificate, then verify it at source. A scope certificate only proves a facility was audited; a transaction certificate is what ties certified material to your shipment. Check the number in the issuing body’s own database, match the product category, site and validity dates, and confirm the recycled percentage is the one you are actually allowed to print.

Ask a pet product factory whether their rope toy is recycled and you will usually get a yes, a photograph of a certificate, and a sentence containing the words eco-friendly and sustainable. None of those three things is evidence. The photograph is often a scope certificate belonging to a yarn mill three tiers up the supply chain, valid for a product category that does not include your toy, and it says nothing at all about the goods in your order.

This is not usually fraud. It is a documentation gap that almost everyone in the chain tolerates, because until recently nobody downstream checked. That has changed: from 27 September 2026 the European Union applies new rules on environmental claims and sustainability labels, and a claim you cannot substantiate is now a regulatory exposure rather than a marketing risk.

This guide covers the four claims that come up most in pet products — GRS and recycled content, FSC for board and natural rubber, rPET, and natural rubber generally — what each one can and cannot prove, the difference between the two documents buyers constantly confuse, and a verification checklist you can hand to whoever runs your supplier files.

Key takeaways

• A scope certificate is not proof of your goods. Textile Exchange states this on the document itself: a scope certificate provides no proof that goods delivered by its holder are certified. Only a transaction certificate covers a specific shipment.
• rPET is a material, not a certification. “Made with rPET” is an unverified description until a recycled-content standard and a chain of custody sit behind it. The same is true of “natural rubber”.
• Two percentages matter and they are different. Under Textile Exchange’s recycled standards, 20% recycled content is the threshold for business-to-business certification; 50% is the threshold for a consumer-facing label.
• FSC has two codes and they answer different questions. The certificate code identifies the certified operation and travels on invoices; the trademark licence code, in the form FSC-C followed by six digits, is what appears on the product and lets anyone look you up.
• The EU deadline has passed. Member States had to adopt Directive (EU) 2024/825 by 27 March 2026 and apply it from 27 September 2026. Generic claims such as “eco-friendly” are prohibited unless you can show recognised excellent environmental performance, and a sustainability label must rest on a certification scheme or be established by public authorities.

What each claim actually proves

Most disputes come from treating all of these as interchangeable badges of greenness. They are not. Each one has a defined subject, and outside that subject it proves nothing.

Scope certificate versus transaction certificate

If you take one thing from this article, take this distinction. It is where nearly every unverifiable claim in this category lives.

The scope certificate

A scope certificate says that a named organisation, at named sites, was audited by a licensed certification body and is authorised to produce certain product categories under certain processes, for a stated validity period. It is about capability and permission. Textile Exchange’s own policy is blunt about the limit: the document “provides no proof that any goods delivered by its holder” are certified. A supplier who answers your material question with a scope certificate has answered a different question.

The transaction certificate

A transaction certificate covers a specific shipment. It names the seller and the buyer with their Textile Exchange IDs, the shipment dates and weights, the material composition, the certified raw materials and quantities, and the product categories claimed. This is the document that connects certified material to your order, and it is the one you should be contracting for before production, not requesting after the goods land. Under Textile Exchange’s current policy a transaction certificate must be issued within 14 calendar days of a complete and valid application, so “it takes months” is not an explanation.

Textile Exchange also operates a single official route for checking one: its Authenticate a Transaction page is the only official source for authenticating transaction certificates. A PDF forwarded by a supplier is a starting point, not a verification. The current version of the policy, TE-TXL-POL-203-V4.0, takes effect on 1 October 2026 and becomes mandatory on 1 April 2027, so if your supplier file was built on the previous version, this is the quarter to re-read it.

The one-line test: does the document name your order — your buyer entity, your shipment, your weights? If not, it is background on the supplier, not evidence about your goods.

The certificate verification checklist

This is the checklist our team runs before any material claim goes into a specification or onto a package. It takes about twenty minutes per certificate and it catches almost everything.

Reading FSC correctly

FSC turns up in pet sourcing in two quite different places: the retail carton and the rubber. Both are legitimate, and both are frequently claimed loosely.

The three labels

• FSC 100% — all material comes from FSC-certified forests.
• FSC Recycled — the product is made from recycled material.
• FSC Mix — a combination of certified material, recycled content and controlled wood. This is what most printed pet packaging actually carries, and it is the label most often described to buyers as if it meant FSC 100%.

The two codes

A chain of custody certificate code identifies the certified operation and is what transmits the FSC claim on sales documents. A trademark licence code, written as FSC-C followed by six digits, is unique to the certificate holder and is what appears on labels and promotional material. Either can be looked up in the FSC public certificate search, and that lookup is the verification — not the logo artwork a supplier emails you.

Two practical consequences for a pet brand. First, if you want to put the FSC logo on your own packaging or website, you need your own licence, not your printer’s: their code covers their claim, not your marketing. Second, an FSC claim on the carton says nothing about the product inside it, and a plush toy in an FSC Mix box is not an FSC product.

Natural rubber

FSC certification does extend to natural rubber: forest management standards cover the plantations, and chain-of-custody certification is what verifies that a manufacturer’s natural rubber products meet the sourcing requirements from forest to finished product. Brands that want to say so on pack need a promotional licence.

Unqualified, though, “natural rubber” is only a statement about chemistry, and in chew toys it is frequently not even that. Ask for two things: the chain of custody certificate covering the rubber, and a composition test from an accredited laboratory on the production sample. A dog toy sold as 100% natural rubber that turns out to contain reclaimed rubber and filler is a product-safety problem before it is a sustainability one, and the composition test is what your pre-shipment inspection cannot tell you.

The two percentages you must not mix up

Textile Exchange’s recycled standards operate two thresholds. For business-to-business purposes, both the RCS and the GRS accept products with at least 20% recycled content. For a consumer-facing label, the threshold is at least 50%. The GRS is the stricter scheme on both counts: it carries the higher minimum recycled percentage for labelling and adds social, environmental and chemical requirements at processing sites that the RCS does not address.

So a rope toy at 30% recycled content can be sold to you as a certified recycled product and legitimately described as such in trade documents, while a claim printed on the retail pack may not be permissible. That single distinction is behind a large share of the packaging that has to be reprinted.

Two further traps. Percentages are per component, not per product: a bed with a GRS-certified outer fabric and virgin polyester filling is not “a GRS bed”, and the honest formula is component weight × certified percentage, summed, divided by total product weight. And pre-consumer and post-consumer material are both accepted as recycled under these standards, so if your marketing implies ocean-bound bottles, that is a separate claim needing separate evidence.

What changed in the EU on 27 September 2026

Directive (EU) 2024/825, on empowering consumers for the green transition, amends EU consumer law by adding practices to the list of those prohibited in all circumstances. Member States had to adopt the measures by 27 March 2026 and apply them from 27 September 2026. Two of the additions matter directly to anyone printing pet packaging for the EU:

• Sustainability labels. Displaying a sustainability label that is not based on a certification scheme, or not established by public authorities, is prohibited. Your own leaf-and-globe badge, designed in-house, is exactly what this addresses.
• Generic environmental claims. Making a generic environmental claim is prohibited unless the trader can demonstrate recognised excellent environmental performance relevant to the claim. “Eco-friendly”, “green” and “climate friendly”, standing alone, are the examples given.

The practical reading for a pet brand: replace adjectives with specifics that a certificate supports. “Eco-friendly dog bed” is a claim you now have to defend. “Outer fabric: 65% recycled polyester, GRS certified, certificate number on request” is a fact. The second is also better copy, because it is the sentence a buyer believes.

This is EU consumer law, transposed nationally, so the enforcement detail and penalties are set by each Member State. Check the position for the markets you actually sell into, and treat this section as the prompt to do that rather than as legal advice.

Phrases to strike from your pack copy

How we handle material claims

Petlland maintains an ESG material library with certificates attached, across 60+ audited partner factories and nine categories, and our partner certifications sit at BSCI, ISO 9001 and FSC. Each material route in that library is published with the document you receive against it rather than an adjective — a GRS transaction certificate for rPET fabric, an FSC chain-of-custody number for retail board and hang tags, GOTS or OCS scope certificates for organic cotton rope, an FDA food-contact report for natural rubber, EN 13432 for compostable inner packing — with the MOQ and the cost impact against the conventional equivalent stated next to it. Two working rules behind that, which you are welcome to copy:

• Certificates are verified at audit, not at order. Entity, site, scope and current status are checked with the issuing body during the factory audit — the same discipline set out in our 15 checks before paying a deposit — so a claim never enters a specification on the strength of a PDF.
• A claim that is not on the invoice does not exist. If certified material is being bought, the claim is written into the purchase order and has to appear on the supplier’s commercial documents for the order, with the transaction certificate agreed before production rather than chased afterwards.

On packaging we quote to a written board specification — for example 350 gsm FSC board with matt lamination on a private label retail carton — because “FSC box” is not a specification and cannot be verified at inspection. And where a claim cannot be evidenced, we say so rather than sourcing a certificate to fit the marketing; that is usually the shortest conversation of the project and always the cheapest.

Six steps to put this in place

1. Decide the claim before you decide the supplier. Write down the exact sentence you intend to print. Everything below is then a test of that sentence rather than an open-ended sustainability review.
2. Ask for the scope certificate and read the four fields — holder, sites, validity, product categories and processes. Most claims fail here, at no cost.
3. Verify the number at source, in the certification body’s or scheme’s own database. A screenshot from the supplier is not a verification.
4. Contract the transaction certificate into the purchase order, with the claim wording, the percentage per component, and the requirement that the claim appears on the invoice and packing list.
5. Test composition on the production sample where the claim is about material content — recycled percentage, rubber composition, fibre blend. Certificates govern the chain; the laboratory governs the substance.
6. Re-verify at every reorder. Certificates expire, scopes change, and sites get added or dropped. A yearly diary note against each supplier file is the whole system.

Common mistakes

• Accepting a scope certificate as shipment evidence. The single most common error in this category, and the document itself says otherwise.
• Taking a certificate from the wrong tier. A yarn mill’s certificate does not certify a finished toy assembled two tiers downstream unless that assembler is also certified and the claim was transmitted on each invoice.
• Printing the consumer label at a business-to-business percentage. 20% lets you buy it as certified; 50% is what a consumer-facing label needs.
• Treating a social audit as a material claim. BSCI and Sedex describe working conditions. They say nothing about recycled content, and offering them in answer is a signal in itself.
• Using your printer’s FSC licence code as your own. Their code covers their claim. Displaying the trademark yourself requires your own licence.
• Letting the marketing copy run ahead of the file. Every green adjective on a pack should map to a document number. Since 27 September 2026 in the EU, that is not just good practice.

Frequently asked questions

How can a buyer verify that an eco-friendly pet product claim is real?

In four moves. Get the scope certificate and confirm that the holder, the site, the validity dates and the product categories match your order. Look the certificate number up in the issuing body’s own public database rather than trusting a PDF. Require a transaction certificate naming your buying entity and your shipment, contracted in the purchase order. Then check that the certified claim actually appears on the supplier’s invoice and packing list, because a claim not transmitted on the commercial documents was not transmitted at all.

What is the difference between a scope certificate and a transaction certificate?

A scope certificate authorises an organisation and its sites to produce certain certified product categories for a validity period; Textile Exchange states that it provides no proof that goods delivered by its holder are certified. A transaction certificate documents a specific shipment — seller, buyer, dates, weights, material composition, certified quantities. Only the second one is evidence about your goods, and under current policy it must be issued within 14 calendar days of a complete application.

Is rPET the same as GRS certified?

No. rPET names a material — recycled polyethylene terephthalate — and carries no verification on its own. GRS is a standard with audited chain of custody plus social, environmental and chemical requirements at processing sites. A supplier can truthfully say a fabric contains rPET and still have nothing that lets you print a recycled claim. Ask which standard, which version, what percentage, and for the transaction certificate.

How much recycled content do I need before I can put it on the label?

Under Textile Exchange’s recycled standards, at least 20% recycled content is accepted for business-to-business purposes and at least 50% is required for a consumer-facing label. Percentages are calculated per component rather than across the whole product, so a certified outer fabric does not make a filled bed a certified product. Confirm the applicable threshold and the exact permitted wording with your certification body before artwork goes to print.

Does an FSC certified box make the pet product FSC certified?

No. An FSC claim covers the forest-based material it was made on — typically the carton, insert or hang tag. The plush, plastic or rubber inside is outside that scope entirely. Note also which label it is: FSC Mix means a combination of certified material, recycled content and controlled wood, which is not the same as FSC 100%. And to display the trademark on your own packaging or site you need your own licence, not your printer’s code.

Can natural rubber be certified?

Yes. FSC covers natural rubber: forest management standards apply to the plantations, and chain-of-custody certification verifies a manufacturer’s natural rubber products from forest to finished goods, with a promotional licence needed to say so on pack. Unqualified “natural rubber” proves nothing about provenance and, in chew toys, often not much about composition either — so pair the chain of custody certificate with a laboratory composition test on the production sample.

What can I no longer say in the EU?

Directive (EU) 2024/825 applies from 27 September 2026, having been due for transposition by 27 March 2026. It prohibits displaying a sustainability label that is not based on a certification scheme or established by public authorities, and prohibits generic environmental claims — “eco-friendly”, “green”, “climate friendly” — unless recognised excellent environmental performance relevant to the claim can be demonstrated. Enforcement is national, so confirm the position in each market you sell into.

The factory says certification would raise the price. Is it worth it?

It depends on whether you intend to make the claim publicly. If you do, the certificate is not an upgrade, it is the cost of the sentence — and an unsupported claim is now a regulatory and marketplace risk as well as a reprint risk. If you do not, buy the better material on its own merits and say nothing about it. What does not work is paying nothing and printing the claim anyway.

Ask for the products whose certificates we can actually produce

Tell us the claim you want to make and the market you are making it in. We will come back with the products in our material library that can evidence it — standard, version, percentage per component, and the certificate holder — and say plainly where a claim you are considering cannot be supported.

Verifying the factory behind the certificate is the companion job: our 15 checks before paying a deposit covers entity, scope and status verification, and the AQL inspection guide covers what a pre-shipment check can and cannot confirm about materials. Planning a first branded range around these materials? Start with launching a private label pet brand at 100 units, and white label versus private label versus OEM for how much of the specification you actually control.
