What the Textile Act Requires on Your Clothing Label

The scratchiest tag in your collar is also the most regulated text in the garment. Since the Textile Fiber Products Identification Act became law in 1960, every covered textile product sold in US commerce has had to state exactly what it is made of, who is responsible for it, and where it was made. The implementing rules sit at 16 CFR Part 303, enforced by the FTC. Read the tag with the statute in mind and it stops being noise.

The three required statements

First, fiber content: the generic names of the constituent fibers with percentages by weight, listed in descending order of predominance. Generic means generic — polyester, not a trademarked fiber brand; rayon, lyocell, modal, not “bamboo” for what is chemically rayon. Decorative trim and ornamentation are excluded from the percentages, the one sanctioned exception. Second, the manufacturer’s or responsible company’s business name, or its RN number in place of it. Third, the country where the product was processed or manufactured. For garments with a neck, the country of origin goes on a label at the inside center of the neck; the fiber and company information can share that label or sit on another one that is just as accessible. Country of origin must appear on the front side of its label.

Wool gets its own law

Wool predates the Textile Act by two decades. The Wool Products Labeling Act of 1939 requires wool products to disclose the percentage of wool, the percentage of recycled wool, and other fibers at five percent or more — “wool” and “recycled wool” are legally distinct grades, never to be blurred. A shoddy blend that quietly counts reclaimed fiber as virgin wool is misbranded. The same act also requires disclosure of the maximum percentage of non-fibrous matter such as fillers and sizing, and demands the same company-identity and origin statements.

RN numbers

A Registered Identification Number is the FTC’s shorthand for a company’s name. Businesses that reside in the United States and manufacture or market covered products can apply; since a policy change years back, each company holds exactly one RN, usable across its textile, wool and fur labeling. The numbers are searchable in a public database on the FTC’s site, which makes them the fastest way to identify who actually stands behind a generic label. If a tag carries neither a company name nor an RN, that is a flag, not a stylistic choice.

What the law does not require

The Act is silent on a surprising amount. Fabric weight in grams per square meter, thread count, the country where the fiber was grown, care instructions — a separate rule covers those — and any sustainability or performance claim are all outside its mandates. That gap is where listing copy does its impression of labeling law: “premium 300gsm fleece” sounds official and is compelled by nothing. What the law does compel is the checkable minimum, which is why it is worth the thirty seconds: verify the percentages sum to something honest, that fibers are named generically, and that someone claims responsibility. That habit is the same audit-first instinct as reading a tote bag listing or auditing a capsule wardrobe — the claims that count are the ones someone is legally obliged to stand behind.
