GOTS vs GRS Explained for Fashion Brands: What Each Certificate Actually Covers

Almost every supplier presentation now carries a row of sustainability logos, and GOTS and GRS are usually side by side. For a buyer, that can make them look interchangeable. They are not. One certifies organic fibre and the way it is processed; the other certifies recycled content and the way it is tracked. Choosing the wrong one, or accepting a logo without the paperwork behind it, is how sustainable collections end up with claims a brand cannot defend.

This guide explains what each standard covers, how scope and transaction certificates work in practice, how to verify a supplier in a few minutes, and which certificate to ask for by product type. It is written from the factory side: MagTexco produces under both GOTS and GRS, so these are the documents we issue and check on every certified order.

What GOTS Covers

The Global Organic Textile Standard (GOTS) is a processing standard for textiles made from organic fibres, most commonly organic cotton. It starts after the farm: the organic status of the raw fibre is certified under recognised organic farming standards, and GOTS then follows that fibre through ginning, spinning, knitting or weaving, dyeing, printing, cutting, sewing and labelling.

A product can carry the GOTS label in two grades. Products labelled organic must contain at least 95% certified organic fibre. Products labelled made with organic must contain at least 70%, with strict limits on the remaining fibres. Beyond fibre content, GOTS sets environmental rules for every processing stage, including restrictions on dyes and chemical inputs and requirements for wastewater treatment, as well as social criteria based on the core ILO conventions. That breadth is why GOTS is considered one of the most demanding textile standards: it certifies not only what the garment is made of, but how it was made.

What GRS Covers

The Global Recycled Standard (GRS), owned by Textile Exchange, verifies recycled content: recycled polyester from post-consumer bottles, recycled nylon, recycled cotton and other reclaimed materials. It tracks that content from the recycler through every processing step to the finished product, so the percentage on your label can be traced back to verified input material.

A product needs at least 20% recycled content to be GRS-certified, and at least 50% to carry the consumer-facing GRS logo. Like GOTS, GRS goes further than counting content: certified sites must meet social and environmental requirements and chemical restrictions. It has a lighter sibling, the Recycled Claim Standard (RCS), which only tracks recycled content without those additional requirements. If a supplier offers RCS where you asked for GRS, that is a different and narrower claim.

Scope Certificates and Transaction Certificates

Both standards rely on the same two documents, and understanding them is the fastest way to separate real certification from a logo on a slide. The scope certificate (SC) is issued to a company by an accredited certification body. It names the certified site, the processes it is certified for (for example, garment manufacturing) and the product categories covered, and it has an expiry date. It proves the factory is allowed to make certified products, not that your order is certified.

The transaction certificate (TC) is what certifies your goods. It is issued per shipment, lists the quantities and the certified fibre content, and links the seller and buyer as certified entities. Without a TC, a certified factory can still ship non-certified goods, and nothing in the paperwork would show it. For any order where you intend to make an organic or recycled claim, the TC should be a contractual deliverable, agreed before production starts, not a request after delivery.

How to Verify a Supplier's Certificate

Verification takes about five minutes and should happen before you approve samples. First, ask for the scope certificate as a PDF and note the certificate number and the certification body. Second, check that number in the public database: GOTS maintains a public database of certified suppliers, and Textile Exchange publishes a database of companies certified to its standards, including GRS. Third, compare the details: is the certificate valid today, is the named site the one actually making your goods, and does the scope cover the process and product category you are ordering?

The most common problems are not forgeries but gaps: a certificate that covers a sister facility, a scope limited to fabric when you are buying finished garments, or a certificate that expires mid-production. A serious supplier will answer these questions without hesitation. At MagTexco, our GOTS-certified fabric sourcing means the mill certificates are collected and checked before bulk fabric is booked, so the chain is complete before cutting starts.

Which Certificate to Require per Product

Organic cotton t-shirts, tops, shirts and dresses: GOTS. It is the standard buyers and retailers recognise for organic claims, and its processing rules cover the dyeing and finishing stages where most environmental impact occurs. Outerwear shells, linings and insulation, swimwear and activewear in recycled polyester or nylon: GRS. Recycled cotton blends: GRS, with the recycled percentage stated on the transaction certificate.

Blends need a closer look. A garment mixing organic cotton with a recycled synthetic may qualify under GOTS, under GRS, or need both, depending on the proportions and the claim you want to print. Agree the exact composition and claim wording with your manufacturer before fabric is booked. For collections built around these claims, our sustainable clothing manufacturer in Tunisia page explains how we structure certified programs from development to delivery.

Common Mistakes Brands Make With Certified Orders

The first is printing the claim before the paperwork exists. Hang tags and care labels are often ordered weeks before bulk production, and if the final transaction certificate shows a different percentage, every label is wrong. Lock the composition first, then print. The second is treating certification as a feature of the factory rather than of the order: a certified factory producing your style in non-certified fabric gives you no right to make any claim at all.

The third is losing the chain at the trims. Sewing thread, labels and interlinings rarely affect a GOTS or GRS claim on their own, but accessories marketed as recycled or organic need their own evidence. Finally, many brands never ask for the transaction certificate until a retailer requests it months later. Make it part of the shipment documents, filed with the packing list and invoice, so the proof is in your hands the day the goods arrive.

Why the Paperwork Matters More Every Season

European rules on environmental claims are tightening, and generic statements such as eco-friendly or sustainable are increasingly treated as unacceptable unless they can be substantiated. A precise claim, such as 95% organic cotton, GOTS-certified, backed by a transaction certificate for that shipment, is exactly the kind of evidence brands will be expected to hold. Building that paper trail into every certified order now is far cheaper than reconstructing it after a retailer or regulator asks.
