The percentages on a U.S. clothing label tell you the garment’s fiber composition by weight, usually from the largest share to the smallest. They do not, by themselves, tell you how soft, warm, durable, breathable, sustainable, or washable the garment will be. To understand a label properly, read the fiber statement together with the separate care instructions, country-of-origin statement, and manufacturer or marketer information.
This guide explains what those disclosures mean, what they leave out, and how to compare garments without treating a label as a complete technical specification.

What the percentages on a clothing tag mean
For covered textile products sold in the United States, the Federal Trade Commission (FTC) Textile Fiber Rule requires generic fiber names and percentages by weight. The percentages describe the relative weight of the fibers that make up the textile product, not the percentage of the garment’s total retail price, surface area, or visual appearance.
The FTC describes the rule this way: “The Textile Fiber Rule requires that certain textiles sold in the United States carry labels disclosing the generic names and percentages by weight of the constituent fibers in the product, the manufacturer or marketer name, and the country where the product was processed or manufactured.”

Fiber names normally appear in descending order of predominance. A label that says 65% rayon / 35% polyester therefore indicates that rayon is the larger share of the product’s fiber weight and polyester is the smaller share. It is a hypothetical example of the ordering convention, not a performance prediction about every rayon-polyester garment.
The rule applies to specified products and has exceptions. It is a U.S. labeling framework, not a universal rule for every textile product or every country. Products sold elsewhere may follow different disclosure requirements.
How to decode a fiber statement step by step
- Find the fiber-content panel. Look for wording such as “fiber content,” followed by generic fiber names and percentages. A hang tag may highlight a particular material, but the sewn-in or attached disclosure is the better place to check the complete statement.
- Read the names, not just the marketing phrase. “Luxury,” “performance,” or “natural” language is not a substitute for the required generic names and percentages.
- Check the order. The first named fiber is generally the predominant fiber by weight, followed by smaller shares.
- Add the percentages. The listed values should describe the fiber composition of the covered textile portion. If the numbers appear confusing, check whether a separate panel describes lining, filling, or another component.
- Look for “other fiber” wording. Very small shares are commonly grouped rather than individually named, subject to important exceptions.
- Read the rest of the label separately. Care directions, origin, and business identity answer different questions from fiber content.
When a garment has several textile components
A jacket, coat, or lined dress can contain a shell, lining, insulation, or other textile sections. A label may describe those components separately rather than presenting one blended percentage for the entire item. Read each statement in context: the shell percentages describe the shell, while a lining or filling statement describes that component. Do not combine the figures from separate panels and assume they represent one uniform fabric.

When the relationship between two panels is unclear, use the manufacturer or marketer information on the label to ask which part each statement covers.
What happens to fibers below 5 percent
Under the FTC’s general approach, a fiber present at less than 5 percent is usually grouped under “other fiber” or “other fibers” instead of being listed by its individual name. That rule is not absolute.
Wool has a specific exception
Wool must be identified by name and percentage even when its share is below 5 percent. A label should not hide a small wool amount inside a generic “other fibers” category.
A small amount can be named for a functional reason
A fiber below 5 percent may be named when it has definite functional significance. Spandex used to provide stretch is the familiar type of example. The fact that a small functional fiber is named does not mean it is a large part of the fabric; it means the fiber’s role is considered significant enough to disclose specifically.
Recommended Free Tools
When a specialty fiber is featured prominently in advertising or on a hang tag, look for its actual percentage in the full disclosure. A product promoted as containing cashmere, for example, should state the cashmere percentage rather than relying on the impression created by the word alone.
A fiber label is not a complete parts list
The fiber statement covers constituent textile fibers, not every material attached to the garment. Non-fibrous components such as buttons, zippers, beads, sequins, and leather patches generally do not have to appear in the fiber disclosure. Some textile trim is excluded as well.

This distinction matters when you are checking a garment for a particular material. A label that says “100% cotton” does not necessarily mean that every visible part is cotton. It describes the covered textile component under the applicable labeling rules. A zipper, decorative patch, elastic hardware, or button may be made from something else without changing that fiber statement.
If an accessory or trim is important to your decision—for example, because of an allergy, a repair plan, or a preference for avoiding animal-derived materials—ask the seller or manufacturer about that component specifically. Do not infer its composition from the main fiber percentage.
Do these 3 things before closing this tab:
1Fix the driver behind crashes, sound loss and screen glitches2Repair Windows errors before they cause bigger problems3Scan for outdated or missing drivers - takes under a minuteFiber content and care instructions answer different questions
Fiber content tells you what fibers are disclosed in the textile. Care instructions tell you how the finished garment should be cleaned and handled. One cannot be used as a replacement for the other.
The FTC’s care-labeling guide states: “The Care Labeling Rule requires manufacturers and importers to attach care instructions to clothing and some piece goods.” For covered garments, care directions must have a reasonable basis, and the label must warn about procedures that could damage the item when that warning is needed.
Why the blend percentage is not enough to choose a wash cycle
A garment’s construction, dyes, finishes, lining, interfacing, trims, and manufacturing process can affect the appropriate care method. Two garments with the same fiber percentages may carry different instructions because their finished constructions differ. Follow the garment’s care label rather than substituting a rule based only on the dominant fiber.
What “Dryclean Only” means
The FTC says a “Dryclean Only” instruction requires evidence that washing would harm the garment. Treat that direction as a care requirement for the finished item. Do not assume that a washable-looking fiber makes machine washing safe.

Use the least damaging method that is practical for the garment and follow any temperature, cycle, bleach, drying, or ironing limits shown. If a warning accompanies an otherwise permitted procedure, the warning is part of the instruction, not optional marketing text.
Country of origin is not the origin of the fiber
The country-of-origin statement concerns where the covered textile product was processed or manufactured. It does not, by itself, identify where cotton was grown, where wool was shorn, where a polymer was produced, or where every stage of the supply chain occurred.
For covered imported products, FTC guidance calls for the specific country rather than a broad region such as “the European Union.” Separate U.S. Customs requirements can also apply, especially when a product has a complex production history. The wording on a label should therefore be read as a manufacturing or processing disclosure, not as complete raw-material traceability.

“Made in [country]” and a fiber statement answer two different questions: what the textile contains and where the covered product was made or processed. Neither statement alone establishes the garment’s entire supply chain.
Why the company name appears on the label
Covered products also identify the manufacturer or marketer, or provide the responsible business information required by the FTC rule. This gives consumers a way to identify the business responsible for the product disclosure.
The identity statement is not a fiber specification. It does not tell you where the fibers came from, who spun the yarn, or who performed every finishing operation. Use it as the starting point when you need clarification about an unusual blend, a component not covered by the fiber statement, or an apparent labeling inconsistency.
What the 3 percent tolerance does—and does not—allow
FTC guidance describes a 3 percent tolerance for unintended variation in textile-product fiber-content claims. The purpose is to allow small, unintended manufacturing inconsistencies. It is not permission to make a knowingly inaccurate claim.
For example, the guidance rejects calling a garment “100% silk” when another fiber was intentionally added. The tolerance does not let a seller choose a more attractive label while knowingly omitting an intentionally included fiber. Read the 3 percent figure as a limited allowance for accidental variation, not as a license to round away a material part of the composition.

How to compare two garments using only label evidence
A label can support a careful comparison, but only along the dimensions it actually discloses. Use the following framework when two products appear similar.
| Comparison point | What the label can establish | What it cannot establish by itself |
|---|---|---|
| Predominant fiber | Which named fiber has the largest disclosed share by weight | That the garment will feel softer, last longer, or keep you warmer |
| Blend percentages | The stated proportions of the listed constituent fibers | A guaranteed difference in shrinkage, breathability, drape, or comfort |
| Specialty fiber | Whether a highlighted fiber is named and quantified in the full statement | That a small specialty-fiber share dominates the garment’s performance |
| Care instructions | The cleaning and handling procedures the manufacturer or importer supports | That another garment with the same blend can be treated identically |
| Country statement | The stated country where the covered product was processed or manufactured | Where every raw fiber or component originated |
| Business identity | The manufacturer, marketer, or responsible business information | The quality, ethics, or environmental impact of the product |
This approach prevents a common mistake: turning a composition label into a universal ranking of fibers. The FTC labeling materials establish disclosure requirements, not a general science of comfort, durability, warmth, environmental impact, or other performance properties.
Common label-reading mistakes
Mistake: treating the first percentage as a quality score
The first percentage identifies the largest fiber share. It does not rate the garment. A higher percentage of one fiber is not automatically better or worse; suitability depends on the garment and your use.

Mistake: assuming “100%” covers every visible part
“100%” refers to the covered textile fiber statement. It does not necessarily include buttons, zippers, beads, sequins, leather patches, or other excluded components.
Mistake: using fiber content as a washing instruction
Do not replace the care label with a generic rule such as “cotton can always be washed” or “synthetics never need special care.” The finished garment’s instructions control.
Mistake: reading a country statement as raw-material traceability
The country statement concerns processing or manufacture under the applicable disclosure. It does not establish the origin of every fiber.
Mistake: trusting a highlighted fiber without finding its percentage
Marketing may emphasize a luxury or specialty fiber. Check the complete fiber disclosure to see how much is actually present.

Mistake: treating “other fibers” as a precise list
“Other fiber” is a permitted grouping for certain small shares. It does not tell you which individual fibers are inside that group unless the business provides more information.
Questions a label cannot settle by itself
Even a complete disclosure may not answer whether a garment is comfortable for your skin, how long it will last, or how much energy and water were used to produce it. Those conclusions depend on construction and manufacturing information that the FTC label statements do not provide. Avoid treating a fiber name as proof of an environmental, ethical, or quality claim.
Likewise, a label cannot identify every adhesive, finish, coating, or piece of hardware. If you need a complete materials inventory for an allergy, religious observance, animal-material concern, or repair, ask the responsible business for details rather than extrapolating from the fiber percentages.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.A practical checklist before you buy or wash
- Identify the generic fiber names and their percentages by weight.
- Confirm that the percentages are presented in the expected descending order.
- Check whether wool or a functionally significant small fiber is named separately.
- Look for the complete disclosure when advertising highlights cashmere or another specialty fiber.
- Inspect the garment for non-fibrous components that the fiber statement may not cover.
- Read care directions independently, including temperature, bleach, drying, ironing, and dry-cleaning instructions.
- Record the stated country of processing or manufacture without treating it as the origin of every raw material.
- Note the manufacturer or marketer information in case you need clarification.
- If a claim appears inconsistent or a material is important to you, ask the responsible business rather than guessing from the label.
Scope and limits of U.S. label rules
The FTC requirements discussed here apply to covered products under U.S. rules. They are not a universal account of every product category, and exceptions can affect what appears on a particular label. Textile products sold in another jurisdiction may use different terminology, thresholds, or required disclosures.

Pick the symptom - the matching free tool is one click away.
These rules also do not make a label a laboratory report. They tell you what the seller must disclose about covered fiber content, care, origin, and business identity; they do not provide a complete assessment of manufacturing quality, environmental footprint, labor conditions, or expected service life.

Bottom line: read the whole label, not one number
Start with the percentages by weight, read them in order, and check how small fibers are grouped or separately identified. Then move to the care instructions, origin statement, and responsible business information. Use the label to establish composition and stated handling requirements, but do not ask it to prove qualities it was never designed to disclose.
Frequently Asked Questions
What do the percentages on a clothing tag mean?
For covered U.S. textile products, they state the proportions of the listed fibers by weight. They are generally shown from the largest share to the smallest; they are not percentages of price, surface area, or a quality rating.
How do I know what fabric my clothes are made of?
Find the complete fiber-content statement and read each generic fiber name and percentage. Check separate statements for a shell, lining, or filling, and remember that buttons, zippers, patches, and other non-fibrous parts may not be included.
Does the fabric label tell me how to wash it?
No. Fiber content and care instructions are separate disclosures. Follow the care directions for temperature, cycle, bleach, drying, ironing, or dry cleaning; the blend percentage alone is not a wash prescription.
What does “other fibers” mean?
It generally groups fibers present at less than 5 percent. Wool must still be named and quantified, and a smaller fiber may be named when it has definite functional significance, such as spandex used for stretch.
Does “100% cotton” mean every part is cotton?
No. It describes the covered textile fiber component. Buttons, zippers, beads, sequins, leather patches, and some trim can be made from other materials without appearing in that statement.
Is “Made in” the country where the fiber came from?
Not necessarily. The origin statement concerns where the covered product was processed or manufactured. It does not by itself identify where cotton, wool, polymers, or every other raw material originated.
Recommended Free Tools
What is the FTC’s 3 percent tolerance?
It allows for small unintended manufacturing variation in a fiber-content claim. It does not permit knowingly adding another fiber and still calling a product “100%” of the advertised fiber.
How should I compare two garments from their labels?
Compare predominant fiber, stated blend percentages, quantified specialty fibers, care directions, stated processing or manufacturing country, and business identity. Do not use those entries alone to rank softness, durability, comfort, sustainability, or other performance qualities.
The Bottom Line
Read the complete fiber statement by weight, then check care, origin, and business identity separately. Labels establish disclosed composition and handling requirements, but they do not describe every component or guarantee a garment’s performance or supply-chain history.
