What GOTS-Certified Organic Cotton Means for Your Brand

What does GOTS-certified organic cotton mean? It means cotton grown to a recognised organic farming standard and then turned into fabric and garments only by companies certified to the Global Organic Textile Standard, at every step from the gin to the sewing floor.

An independent certification body checks each of those steps, not just the fibre: the dyes and chemicals used, the wastewater treatment and the working conditions. A product labelled "organic" under GOTS contains at least 95% certified organic fibre, and one labelled "made with organic materials" at least 70%.

"Organic" and "sustainable" get printed on a lot of labels that can't back them up. GOTS — the Global Organic Textile Standard — is the one that can. If sustainability is part of your brand's promise, understanding GOTS is how you make that promise real instead of just marketing. Here's the honest, detailed version — from a factory that actually holds the certificate.

The short version: a real GOTS certificate means the organic fibre, the chemistry, the environmental controls and the working conditions were all independently verified across the whole processing chain — gin to finished garment — and the certified company can show you a numbered scope certificate that says so. Everything below is how that works, and how to use the claim without overstating it.

What GOTS actually certifies

GOTS does not certify the cotton field: the farm holds its own certificate under an organic farming standard, such as the EU organic regulation or the USDA National Organic Program. GOTS starts at the first processing step, which for cotton is ginning, and tracks a textile across its entire processing chain — through spinning, knitting or weaving, dyeing and finishing, all the way to the labelled, finished garment. Every processor, manufacturer and trader in that chain has to be certified for the final product to carry the label. It's managed by the non-profit Global Standard and is widely regarded as the leading standard for organic textiles worldwide. GOTS 7.0 has applied since 1 March 2024. Version 8.0 was released in March 2026, and a corrected GOTS 8.1 on 22 June 2026. All audits from 1 March 2027 use 8.1, and companies may adopt it earlier. Last verified: 23 September 2026.

• Organic fibre — cotton (or other natural fibre) grown to a recognised organic farming standard, without synthetic pesticides or GM seed.
• Clean chemistry — a ban on toxic inputs in processing, with every dye and auxiliary screened for toxicity and biodegradability.
• Environmental management — wastewater treatment and environmental controls required at every facility.
• Social criteria — fair, safe, humane working conditions audited along the whole chain.

The two GOTS labels: know the difference

This is the detail most brands miss — and getting it wrong is how honest brands accidentally overclaim. GOTS has two label grades, set by how much certified-organic fibre a product contains:

• "Organic" — at least 95% certified organic fibres (the small remainder is tightly restricted).
• "Made with organic materials" — at least 70% certified organic fibres.

Below 70% organic content, a product can't carry the GOTS label at all. So match your wording to the grade: for a 70% blend, "made with 70% organic materials" is honest; "100% organic" is not. That form of words is one of the pre-approved claims in GOTS's September 2026 practical guidance for reviewing GOTS/GRTS-related claims, which explains that GOTS certifies the processing of textile goods made with organic fibre, not the raw cotton itself.

What GOTS bans — and what changed in 7.0

The environmental rules are strict and specific. GOTS prohibits the hazardous inputs common in conventional textiles — toxic heavy metals, formaldehyde, aromatic solvents, functional nano-particles, and genetically modified organisms — and seed cotton is tested for GMO contamination. PFAS ("forever chemicals") are banned as well. That ban predates 7.0: version 7.0 kept it, reworded it to cover all PFAS compounds, and also kept the bans on conventional cotton and virgin polyester. What 7.0 did change: recycled synthetic fibres were cut to at most 20% of a product, quinoline was added to the banned list, and the limit for free aniline fell from 100 to 20 mg/kg. From 1 March 2027, version 8.1 tightens PFAS limits and testing again. Every dye and auxiliary must meet toxicity and biodegradability criteria, and every facility must treat its wastewater.

What changes in GOTS 8.0 and 8.1, and when?

The new rules apply from 1 March 2027, when every GOTS audit moves to 8.1, the corrected text of 8.0. Until then 7.0 stays in force, though a company may adopt the new version early. Four areas change in ways that matter for a knitwear order. PFAS: the residue limit covers every PFAS compound, under 25 ppb each and under 250 ppb combined (section 5.2.7.2). Fibre: the 20% ceiling on recycled synthetics rises to 30% for socks and for fibre recycled textile to textile, while virgin elastane and polyamide stay capped at 10% (3.2.10). Workers: where extreme heat, floods or storms are an identified risk, the certified company needs an emergency plan for stopping work, evacuating people and reaching medical care (4.4.7.15). Climate and water: Scope 1 and 2 emissions must be calculated at least once a year (4.3.11.4), and processors need a plan to find the stages that may shed microfibres into wastewater (4.3.13.11). Last verified: 23 September 2026.

The part people forget: the people

GOTS is not only an environmental standard — it's a social one, which is what separates it from a bare "organic fibre" claim. Its social criteria are built on the core conventions of the International Labour Organization (ILO): no child labour, no forced labour, freedom of association and collective bargaining, no discrimination, safe and hygienic conditions, wages at or above the legal minimum with a plan to close the gap to a living wage, and limits on working hours. GOTS 7.0 goes further, requiring certified companies to run human-rights due diligence across their own operations and supply chain, modelled on the UN Guiding Principles on Business and Human Rights and the OECD guidelines. A GOTS garment makes a claim about the workers, not just the cotton.

How to verify a GOTS certificate (don't take it on trust)

Anyone can type "GOTS" on a website. Here's how to check a real one — the exact process serious buyers use:

• Ask for the Scope Certificate. It certifies a company and names the certified entity, the accredited certification body, the product categories in scope, and a licence/certificate number.
• Check that number on the public database. GOTS maintains a public certificate database — search the company or certificate and confirm it's valid and current.
• Check the scope covers your product. A certificate can cover some processes or products and not others — make sure yours falls inside it.
• For a specific order, ask for a Transaction Certificate. The Scope Certificate says a company can make GOTS goods; a Transaction Certificate proves a particular shipment actually was.

A genuine manufacturer shares all of this without hesitation. For ours, ask us for the RSC 9687 scope certificate and we will send you the document itself.

Scope certificate or transaction certificate: what each one proves

Two GOTS documents get confused, and they answer different questions. A scope certificate is about a company: it names the certified unit, the certification body that issued it, its validity period and the product categories it covers. A transaction certificate is about one shipment: it names the products, the quantities and the buyer, and it is what a retailer, marketplace or auditor will want as proof that your goods came through the certified chain.

A certificate never covers a whole company or a whole chain. It covers a named unit and a named list of processes. Ours, RSC 9687, covers what happens on our own floor: cutting, sewing and assembly of certified garments, segregated handling and storage of certified goods, the transaction certificates for the orders we ship, arranged with the certification body that issues them, and our own annual third-party audit. Spinning, knitting, dyeing and finishing are done at partner units that hold their own scope certificates, and the chain-of-custody paperwork is passed down the chain and checked on receipt. If a supplier's certificate appears to cover every stage from fibre to finished carton, it is either an unusually large vertically integrated group or somebody else's certificate described as its own.

In practice a certified order differs from a conventional one in four places:

• You specify it. Certification is not automatic on every order: the same floor also runs conventional cotton for brands that do not need the claim.
• Each colour is a certified dye lot. It is dyed with approved dyestuffs at a certified dye house, with its own lab dip and its own transaction paperwork, so fewer colourways keep the paperwork simple.
• Trims must be compliant. Sewing thread, labels, drawcords and elastics come from GOTS-compliant options, not the cheapest available.
• The label grade is settled first. Which wording you may print depends on your fabric's fibre composition, so it is confirmed in writing before any label is ordered.

None of this needs a bulk order. We make organic cotton styles in our GOTS-certified facility from 150 pieces per style and colour, with the scope certificate sent on request and a transaction certificate arranged for your shipment when you ask for one.

Organic, "natural" and chemical-test labels: what GOTS adds

These get muddled constantly, so here's the plain distinction:

• GOTS — certifies organic fibre content plus environmental and social criteria across the whole supply chain.
• OEKO-TEX STANDARD 100 — tests the finished product for harmful substances. Valuable, but it does not require organic fibre or cover farming and labour. A garment can hold both.
• "Natural," "eco-friendly," "green" — unregulated marketing words with no agreed meaning. On their own, they prove nothing.

GOTS vs OCS: fibre content, or processing and people too

Textile Exchange, which runs the Organic Content Standard (OCS), gives the difference in its own FAQ: GOTS has additional processing requirements, a 70% minimum, and restrictions on the other fibres that may be blended in. OCS verifies organic content and its chain of custody for products containing at least 5% organically grown material (OCS-101, version 3.0). It does not add GOTS's chemical, wastewater and ILO-based labour criteria for mills and factories. An OCS claim tells you how much certified organic fibre is in a product; a GOTS claim also tells you how it was dyed, finished and sewn, and under what working conditions. As of 23 September 2026, Textile Exchange is moving OCS into its Materials Matter Standard. It released the criteria on 12 December 2025; the standard takes effect on 31 December 2026 and becomes mandatory on 31 December 2027, and the detailed OCS pathway is still to be announced. We do not hold OCS certification.

How to find a GOTS-certified manufacturer

Start with the GOTS public database of certified suppliers rather than with a search engine. It lists every certified entity with its country, its certification body and the processes and products its certificate covers. Filter for the process you actually need. A garment maker should be certified for manufacturing; a company certified only for trading buys and sells certified goods but does not make them.

Then check three things for each name: that the certificate is current, that it names the site that will sew your garments rather than only a head office, and that the product categories cover what you are making. Our certificate is RSC 9687; ask us for the scope certificate and we send you the document itself.

How a factory gets GOTS certified

A factory applies to one of the certification bodies approved by GOTS. The certifier inspects the site, the chemical inputs, the wastewater treatment and the social criteria, then issues a scope certificate listing the processes and products it covers. The inspection is repeated every year, and the certificate is renewed only if the site passes. Every stage of processing and trading in the chain needs its own certificate, which is why one certified mill does not make a garment certified.

Whether your brand itself needs to be certified or registered to use the GOTS label depends on what you do with the goods and on your turnover. GOTS sets this out in its licensing and labelling rules, and the certifier of your factory can tell you which applies before you print a label.

Why your customers care

Shoppers — especially the ones who pay a premium for considered brands — have learned to be sceptical of vague green claims. A recognised certification cuts through that. It lets you say "GOTS-certified" instead of "eco-friendly," and back it with a certificate rather than a vibe. That's trust you can prove, which is exactly what a young brand needs.

A vague green claim invites doubt. A certificate ends the argument.

How to use it honestly

• Only call a product GOTS-certified if that specific product qualifies — don't apply it brand-wide unless every item does.
• Keep your certification documentation handy; serious buyers and retailers will ask.
• Pair the claim with the human story — who made it, and under what conditions.
• Be precise: name the grade and the real percentage ("made with x% organic materials"), the form GOTS's September 2026 claims guidance approves; "100% sustainable" usually isn't honest.

Does it cost more?

Certified organic fabric generally costs more than conventional, because the farming and processing are more demanding. But for many brands it pays back: a clearer story, a reason to charge a fair price, and access to retailers who now require it. It's less an expense than a positioning choice.
