Summary
GOTS vs OCS organic cotton: USDA’s National Organic Program certifies agricultural production and rarely applies to finished garments, GOTS certifies the processed textile plus social and environmental criteria at a 70% or 95% organic fiber threshold, and OCS verifies organic fiber content only, from 5% up to 100%. Only a transaction certificate for your specific order, not a supplier’s word or a scope certificate, proves your fabric is actually covered.
“The Supplier Said It Was Organic”
A supplier tells you the fabric is organic cotton. You believe them because why wouldn’t you? they’re the experts, and the price reflects a premium fiber. You put “organic” on your product page and move on.
Then a customer, a competitor, or the FTC asks you to prove it, and you realize you have nothing but a conversation to point to.
This happens constantly, and it happens because organic status isn’t a quality you can see or feel in a fabric; it’s a documented chain of custody, verified at every ownership transfer. A verbal assurance from a supplier proves nothing, no matter how confident they sounded.
At Affix Apparel, we carry USDA Organic marks ourselves, so this isn’t theoretical for us. Here’s what GOTS vs. OCS organic cotton actually means, what each label lets you say, and what paperwork you need before you say it.
Three Different Certifications, Three Different Questions
The confusion starts because USDA NOP, GOTS, and OCS all touch the word “organic,” but they answer entirely different questions.
USDA National Organic Program (NOP): Certifies the Farm, Not the Garment
The USDA National Organic Program is the federal regulatory framework defining what counts as “organic” agricultural production in the United States, including organically grown fiber crops like cotton. It governs how the crop was grown: no synthetic pesticides or fertilizers, no genetically modified seed, and strict record-keeping on the farm.
Here’s the detail that trips up almost every apparel buyer: NOP was built for food and raw agricultural products, not finished textiles. For a garment to legally carry the USDA Organic seal, not just the raw cotton but every processing step, dyeing, and finishing, all of it, must comply with NOP’s extremely restrictive food-grade chemical list. Very few textile mills operate under those restrictions, which is why the USDA Organic seal is common on raw fiber and rare on finished apparel.
In practice, most brands source NOP-certified organic cotton at the fiber stage, then process it under GOTS instead, which brings us to the standard actually built for finished textiles.
GOTS: Certifies the Processed Textile, With Social Criteria Attached
The Global Organic Textile Standard (GOTS) picks up where NOP-style fiber-growing rules leave off and covers the entire chain from harvested fiber to finished, labeled product. It requires a minimum organic fiber content, restricts what non-organic inputs are allowed, and, critically, layers on environmental requirements (wastewater treatment, restricted chemical inputs) and social requirements (labor rights, safe working conditions, no child labor) that neither NOP nor OCS touch at all.
A 2011 USDA NOP policy memo explicitly confirmed that U.S. textile products manufactured under GOTS may be sold as “organic” domestically, even without NOP certification or the USDA seal, which is the main reason GOTS, not USDA Organic, is the certification most finished-apparel brands actually pursue.
Organic Content Standard (OCS): Verifies Content Only, Nothing Else
The Organic Content Standard (OCS), administered by Textile Exchange, answers a narrower question: how much certified organic material is actually in this product? OCS tracks organic fiber content through a chain of custody from farm to finished item, using the same transaction-certificate mechanism GOTS relies on.
What OCS explicitly does not cover: environmental practices, chemical use, wastewater, or labor conditions. It’s a pure content-verification standard, useful, but answering a much smaller question than GOTS asks.
The Percentage Thresholds That Decide Your Wording
This is the part that creates the most live FTC exposure, because the wording you’re allowed to use changes hard at specific percentage lines, there’s no gradual scale of acceptable claims.
GOTS: Two Grades, Two Different Claims
| GOTS Label Grade | Organic Fiber Content | What You Can Say |
| “Organic” | At least 95% | “Organic [fiber]” |
| “Made with Organic Materials” | Between 70% and 94% | “Made with [X]% organic materials” |
A GOTS-certified label must state the grade, the certifier’s name, and the license number directly alongside the logo, none of this is optional cosmetic branding. A product with 80% organic fiber content cannot be labeled simply “organic” under GOTS; it must say “Made with 80% organic materials,” full stop.
OCS: Two Tiers, From Blended to Nearly Pure
| OCS Category | Organic Fiber Content | What It Verifies |
| OCS 100 | 95%–100% | High organic content, minimal blending |
| OCS Blended | 5%–94% | Organic fiber blended with conventional, synthetic, or recycled material |
OCS’s lower entry threshold (just 5%) is exactly why it’s a weaker organic claim on its own than GOTS; it can verify a genuinely blended, mostly conventional product, which is a very different thing to put on a hang tag than a GOTS “organic” grade at 95%+.
The 60% Blend Trap
Here’s the exact mistake the research behind this article flagged: a brand sources a 60% organic cotton blend, sees “organic” mentioned somewhere in the paperwork, and puts “organic cotton tee” on the product page. Under GOTS, 60% doesn’t even clear the 70% floor required for “made with organic materials”; it doesn’t qualify for any organic wording tier at all without additional context. That’s not a labeling nuance; it’s a claim with no certification behind it whatsoever.
Scope Certificates vs. Transaction Certificates: The Part Nobody Explains
This is the mechanism that actually determines whether your organic claim is defensible, and it’s almost never covered outside of certifier documentation itself.
A Scope Certificate Covers the Facility, Not Your Order
A scope certificate confirms that a specific facility, a spinning mill, a dye house, a cut-and-sew factory is certified to process organic fiber under GOTS or OCS. It’s proof the facility is capable of compliant production.
It is not proof that your specific order was made from certified organic material. A factory can hold a valid scope certificate while also running plenty of conventional-cotton orders through the same building. Seeing a scope certificate is a good sign; it’s not the document that substantiates your claim.
A Transaction Certificate Covers Your Actual Order
A transaction certificate (TC) is issued for a specific transaction, a specific quantity of certified organic material, moving from one certified party to the next, at a specific point in the supply chain. This is required at every ownership transfer, from ginner to spinner to fabric mill to garment manufacturer, and it’s the only document that ties certified organic status to the literal fabric that ended up in your order.
The rule worth remembering: a scope certificate tells you the factory can make organic-certified products. A transaction certificate tells you this specific batch actually was. Only the second one lets you make the claim with a straight face.
Before placing an order where “organic” appears anywhere on your marketing, request the transaction certificate covering that exact shipment, not a general scope certificate, not a supplier’s verbal confirmation, and not a certificate from a previous, unrelated order.
FTC Green Guides | What “Substantiation” Actually Means
The Federal Trade Commission’s Green Guides govern environmental marketing claims in the U.S., including organic claims on fiber and textile products, a category that, notably, falls outside USDA NOP’s direct enforcement scope, leaving the FTC as the primary federal authority for policing misleading textile organic claims.
The core principle is simple and unforgiving: any objective claim needs competent and reliable evidence behind it before you make the claim, not gathered defensively after someone asks. “Organic” is an objective, verifiable claim, not a vibe, not a marketing adjective. If asked to substantiate it, “our supplier told us” is not evidence. A valid transaction certificate matching your specific order is.
This is exactly where greenwashing exposure lives for small brands, not in dishonest intent, but in genuinely not knowing that a verbal assurance was never sufficient in the first place.
A Documentation Checklist Before You Place an Order
Request all of the following before any organic claim goes anywhere near your product pages:
- The specific certification standard: GOTS or OCS, and which grade or tier (GOTS Organic vs. Made With; OCS 100 vs. Blended).
- The transaction certificate covering your exact order quantity and date, not a general scope certificate.
- The certifier’s name and license number, matching what would appear on a compliant label.
- The certified organic fiber percentage, stated as a number, not a rounded-up marketing figure.
- Confirmation the certificate is current: certifications lapse and get renewed, the same way any textile certification does.
If a supplier can’t produce a transaction certificate for the specific batch you’re buying, treat “organic” as unconfirmed, regardless of how the fabric was described in the sales conversation.
What You Can Actually Say, By Certification Level
- GOTS, 95%+ organic fiber: “Organic cotton,” the strongest, cleanest claim available.
- GOTS, 70–94% organic fiber: “Made with [X]% organic cotton,” accurate, and still a genuinely strong sourcing story.
- OCS 100 (95–100%): “Made with certified organic cotton,” verified content, without the environmental and social claims GOTS covers.
- OCS Blended (5–94%): A specific percentage claim only, “contains [X]% organic cotton”, never an unqualified “organic” label.
- No transaction certificate for the specific order: No organic claim at all, regardless of what a supplier said.
Fiber certification is only one part of a fully defensible sourcing story; social and labor conditions in the supply chain are a related but separate question and worth reading about in our fair trade fashions piece rather than repeating that ground here.
Say What You Can Prove
“Organic” is one of the most valuable words on a hang tag and one of the easiest to lose the right to use. The difference between a defensible claim and a genuine FTC liability isn’t intent; it’s a piece of paper. Specifically, a transaction certificate that names your exact order, not a scope certificate for the building or a supplier’s confident tone on a call.
Know which standard you’re working with, know your threshold, and ask for the document before the claim ever reaches a product page.

Frequently Asked Questions
Can I say my clothing is organic?
Only if you can produce a transaction certificate covering your specific order, showing certified organic fiber content at or above the threshold your chosen standard requires, 95% for a GOTS “organic” claim or verified content under OCS. A supplier’s verbal assurance or a general scope certificate doesn’t substantiate the claim on its own.
What is the difference between GOTS and OCS?
GOTS certifies the finished textile’s organic fiber content at a 70% or 95% threshold and adds mandatory environmental and social criteria across the whole supply chain. OCS verifies organic fiber content only, from 5% (Blended) to 95–100% (OCS 100), with no environmental or labor requirements attached.
What is a transaction certificate?
A transaction certificate is a document issued for a specific shipment of certified organic material as it moves from one certified party to the next in the supply chain. It’s the only document that proves your specific order, not just the facility that made it, was made from certified organic fiber.
Does organic cotton need to be 100% organic to be labelled organic?
No. Under GOTS, 95% or more organic fiber content qualifies for an unqualified “organic” label, while 70–94% requires “made with [X]% organic materials” wording instead. Content below 70% doesn’t qualify for organic wording under GOTS at all.
Is USDA Organic valid for textiles?
Yes, but it’s uncommon on finished garments. USDA NOP certification applies primarily to how the raw fiber was grown, and for a finished product to carry the USDA Organic seal, all processing steps must meet NOP’s strict food-grade chemical standards, which most textile mills don’t operate under. Most finished-apparel brands source NOP-certified fiber, then process and label it under GOTS instead.
