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

What to take away

• US labeling rules circular fashion claims are enforced through three agencies: the Federal Trade Commission, the Consumer Product Safety Commission and U.S. Customs and Border Protection.
• Fiber content is defined in 15 U.S. Code section 70, and a false or misleading fiber claim is misbranding under 15 U.S. Code section 70b.
• CPSC apparel rules under the Flammable Fabrics Act apply to clothing sold at resale, not only to new goods.
• CBP requires imported textiles to carry a country of origin marking before they enter US commerce.
• A hangtag or product page can describe repair, resale and recycled content if the wording matches the fiber and the substantiation you hold.

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. 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. The claim must match the actual fiber composition of the item.

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.

Under that section, a covered product must be labeled with the fiber content by generic name and percentage. The label must also name the manufacturer or marketer and the country of processing or manufacture.

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.

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 statute is the basis for the standards that apply to clothing sold in the US.

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. 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.

A repair that replaces a component must keep the label accurate. If a brand swaps a cotton trim for a polyester trim, 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.

A simple check before listing a repaired item: does the fiber content on the label still describe the item as sold? If not, the listing needs an update.

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 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

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.

Fiber content claims must match the item. "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.

Repair and resale claims that stay inside the rules

A repair claim stays inside the rules when it describes the service and the item, not an environmental outcome. "We repair zippers on this jacket" is a service claim.

A resale claim stays inside the rules when it describes the transaction and the condition. "Previously worn, inspected, and resold" is a condition claim.

A recycled content claim stays inside the rules when it states the material and the percentage. "Shell: 100% recycled polyester" is a fiber claim with a recycled attribute.

A claim about diverting textiles from landfill is an environmental claim. It needs evidence, such as a documented reuse chain with weights or counts.

A claim about a take-back program is a program claim. It should state what happens to the item and who operates the program.

A claim about repair extending product life is a durability claim. It is easier to defend if the brand tracks repair outcomes and failure rates.

A claim about a garment being recyclable is a claim about infrastructure. It should name the recycling route and the fiber the route accepts.

A checklist for a repair or resale claim before it goes to print:

• The fiber content on the claim matches the item as sold.
• The country of origin marking is present and legible.
• The environmental claim has written substantiation on file.
• The claim does not imply a fiber content that is not on the label.
• The claim does not promise an outcome the program cannot deliver.
• The claim is consistent across hangtag, product page and resale listing.
• The claim has been reviewed by someone outside the marketing team.

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 resale condition. The listing states the item is previously worn and inspected. The condition claim is documented.

Step 4: Confirm the country of origin marking. The jacket carries a legible origin marking. The import marking rule is met.

Step 5: 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.

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.

Common questions

Do US labeling rules apply to resale items? Yes. A resold garment is still a textile fiber product. Fiber content, care and origin marking rules continue to apply to the item as sold.

Can a hangtag say the item is circular? It can if the word circular is tied to a specific, documented feature. A bare "circular" claim without support is an environmental claim that is hard to defend.

Does a repair change the fiber content label? It can. If a repair replaces a component with a different fiber, the fiber content on the label may need to be updated to match the item.

Who enforces fiber content claims on a product page? The FTC enforces advertising claims, and the CPSC enforces fiber content and labeling rules for apparel. A false fiber claim on a product page can trigger both.

Do imported used textiles need a country of origin marking? Yes. CBP requires imported textile products, including used goods, to carry a legible country of origin marking visible to the buyer.

What is the safest circular claim wording? State the fiber and percentage, then state the service or program in plain terms. Keep the environmental claim specific and tied to a documented outcome.
