How US labeling rules shape circular fashion claims for resale and repair

What to take away

Why circular fashion claims run into US labeling law

A resale listing is a textile fiber product offered for sale. That single fact pulls the listing into the same labeling regime as a new garment on a department store rack.

The Federal Trade Commission sets the advertising side through the Green Guides, formally the Guides for the Use of Environmental Marketing Claims at 16 CFR Part 260 (2012 edition). The Consumer Product Safety Commission sets fiber content and flammability rules for apparel. U.S. Customs and Border Protection sets marking rules at import.

Most circular claims are not pure marketing. They describe fiber content, origin, care or safety. Each of those is a regulated statement.

A brand that writes "made from 100% recycled cotton" on a repair page is making a fiber content claim.

A brand that writes "compostable" on a hangtag is making an environmental claim. The FTC Green Guides ask for competent and reliable evidence for that claim.

Circularity language often mixes two regulated ideas in one line. A single sentence can be both a fiber claim and an environmental claim.

That is why a circular fashion design program needs a labeling review before launch, not after a complaint. The rules apply to the words, not to the intention behind them.

Fiber content and labeling rules under 15 U.S. Code section 70

The statute at 15 U.S. Code section 70 gives the legal definitions of textile fibers and the labeling duties that follow. It defines what counts as a textile fiber product and what a label must disclose.

Generic fiber names matter. "Cotton" and "polyester" are defined terms. A brand cannot invent a fiber name or use a trade name in place of the generic one.

A recycled fiber still needs a generic name. Recycled cotton is labeled as cotton. The recycled content is an additional claim, not a substitute for the fiber name.

Misbranding is the enforcement hook. Under 15 U.S. Code section 70b, a textile fiber product is misbranded if its label is false, misleading or missing required information. The same section covers falsely advertised fiber content. The FTC can seek civil penalties that typically start at $10,000 and can reach over $50,000 per violation, depending on the annual inflation adjustment.

A resale platform that lists fiber content is making a label statement in substance. If the listing says "100% linen" and the item is a linen blend, that is a misbranding risk.

The practical rule is simple: the fiber content on the hangtag, the product page and the resale listing must match. A change in wording is a change in the legal claim.

This is also where the sustainable fashion checklist does the heavy lifting. A certification mark on a label is a claim that must be current and correctly applied to the item.

CPSC flammability and fiber content requirements for apparel

The Consumer Product Safety Commission enforces the Flammable Fabrics Act, which sets flammability standards for wearing apparel and other textile products. The apparel standards are 16 CFR 1610 for clothing textiles, 16 CFR 1615 for children's sleepwear sizes 0 through 6X, and 16 CFR 1616 for children's sleepwear sizes 7 through 14.

Those standards apply to apparel textiles, including garments that enter resale. A used garment is still wearing apparel. The flammability standard does not expire when the item is resold.

The CPSC also maintains fiber content and care labeling rules for apparel. The care labeling rule is 16 CFR 423, and these rules sit alongside the FTC textile rules and are enforced through CPSC regulations and standards.

A repair program can change a garment in ways that affect its regulated status. Adding a lining, a trim or a new fabric panel can change the fiber content and the care instructions.

If a brand swaps a cotton trim for a polyester trim in a repair, the fiber content label may need to change.

Resale sellers should treat a repaired garment as a new labeling event. The item is still the same product, but the fiber content may no longer match the original label.

CBP import marking and labeling rules for resale goods

U.S. Customs and Border Protection requires imported textile products to carry a country of origin marking. The marking must be legible, indelible and visible to the buyer who receives the item in the US. CBP can detain or seize a shipment that lacks a compliant marking.

CBP publishes informed compliance publications on textile labeling, fiber content and import marking. These are the agency's own guidance documents for importers.

A circular import can complicate origin. A garment made in one country and finished or repaired in another may have a different origin for marking purposes.

A brand that imports used textiles for resale must still meet the marking rules. Used goods are not exempt from country of origin marking.

The marking must survive normal handling and washing. A hangtag that falls off does not satisfy the requirement if the marking is not also on the item.

A resale program that imports repaired goods should confirm the marking before the goods enter commerce. This is a customs question, not only a marketing question.

If you want to know how to circular fashion design across borders, the origin marking is part of the same logistics decision. The marking follows the item, not the seller's story.

What a hangtag or product page can legally say about circularity and repair

A hangtag or product page can describe circularity if the statement is true, substantiated and not a fiber claim in disguise. The limit is not the word circular. The limit is the factual claim behind it.

"Made with recycled polyester" is acceptable if the item contains recycled polyester and the percentage is disclosed where required.

Environmental claims fall under the FTC Green Guides. A broad claim like "sustainable" is hard to defend. A specific claim like "contains 40% recycled content" is easier to substantiate.

Repair claims are usually service claims, not fiber claims. "We repair this garment" is a statement about a service. It does not need a fiber content label unless the repair changes the fiber content.

Resale claims are product claims. "This item is resold" is a fact. "This item is circular" is a conclusion that needs support.

A hangtag that says "designed for circularity" is a design claim. It should be tied to a documented design feature, such as mono-material construction or a take-back program.

A product page that says "100% biodegradable" is an environmental claim. Without substantiation, it is a risk under the Green Guides and a possible misbranding issue if it touches fiber content.

The safest pattern is to separate the fiber claim from the circular claim. State the fiber content in the label format. State the circular feature in plain service language.

This separation is also useful for teams working on sustainable fashion problems. It forces the design brief to name the feature that the claim depends on.

Documenting a circular claim before it goes to print

Documentation is the difference between a claim and a liability. The FTC Green Guides expect substantiation before a claim runs, not after a challenge.

A worked example shows how this works in practice. A brand sells a repaired denim jacket through its resale channel.

The brand wants to print: "Repaired, resold, and made with 100% recycled cotton." The claim has three parts. Each part needs its own support.

Step 1: Confirm the fiber content. The jacket shell is recycled cotton. The label reads cotton with a recycled content disclosure. The fiber claim matches.

Step 2: Confirm the repair. The repair log shows the zipper replacement, the date and the technician. The repair claim is documented.

Step 3: Confirm the environmental claim. The recycled cotton percentage is supported by a supplier declaration. The claim is substantiated.

The brand can print the sentence because each part is supported. If any part fails, the sentence changes. The resale condition and the country of origin marking belong in the claim file, covered by the inspection record and the marking photo.

A claim file should hold the fiber test report, the supplier declaration, the repair log, the origin marking photo and the approval record. This file is the defense if a regulator or a customer asks.

The file also speeds up the next claim. A brand with a claim file can reuse the evidence for a similar item instead of starting over. Running a proper check on bio-based fiber problems is the fastest way to build that file.
