Why labeling matters before fulfillment
Apparel labeling matters before fulfillment because most required labels are sewn in at the factory. By the time garments reach a warehouse, fixing a missing or incorrect label means rework, delays or even holding back inventory.
This guide is a general overview, not legal advice. Rules depend on product type, materials and where you sell, so confirm specifics with a compliance professional or the regulator's own guidance. What follows covers the requirements most U.S. apparel brands encounter and the parts of labeling a fulfillment partner can help with.
Fiber content and the Textile Act
The Textile Fiber Products Identification Act, enforced by the Federal Trade Commission, requires most textile apparel to be labeled with fiber content, country of origin and the identity of the manufacturer or another responsible company.
Fiber content is generally listed by generic fiber name and percentage by weight, in order of predominance, such as 60% cotton, 40% polyester. Wool products have additional requirements under the Wool Products Labeling Act, and fur products under the Fur Products Labeling Act.
The FTC's guidance explains exceptions, tolerances and how to label items with trims, linings or multiple components.
Care labels
The FTC Care Labeling Rule requires most textile apparel to have a permanent care label with at least one safe method of care, such as washing or dry cleaning instructions, along with any warnings needed to prevent damage.
The label must stay legible for the useful life of the garment and be easy for the consumer to find. Brands may use words, symbols or both, though symbols are allowed only under defined conditions. Make sure care instructions are accurate for the full garment, including trims and decorations, because a wrong instruction can lead to damaged garments and returns.
Country of origin and Made in USA claims
Country of origin labeling tells customers where the garment was made. Under the Textile Act, imported products are labeled with the country where they were processed or manufactured, and U.S.-made products may be labeled Made in USA only if they meet the FTC's standards.
Online and catalog listings for textile products also must disclose whether a product is made in the United States, imported or both. Make sure product pages match the labels on the garments. U.S. Customs also has its own country-of-origin marking rules for imported goods.
RN numbers and company identification
An RN number, or Registered Identification Number, is issued by the FTC to U.S. businesses that manufacture, import, distribute or sell textile, wool and fur products. It can be used on labels instead of a company name to identify the responsible business.
RN numbers are optional, but they are common because they keep labels short and stay with the company even if branding changes. A company can apply for one through the FTC.
Flammability, children's products and chemical rules
Several other rules may apply depending on your products and markets.
- The Flammable Fabrics Act and CPSC standards set flammability requirements for clothing textiles, with stricter rules for children's sleepwear.
- Children's apparel is subject to the Consumer Product Safety Improvement Act, including tracking labels, a Children's Product Certificate and limits on lead and certain phthalates where applicable.
- California's Proposition 65 may require warnings for products that expose consumers to listed chemicals.
- Several states, including California and New York, have restricted intentionally added PFAS in apparel.
Confirm current requirements before production, since these rules continue to change.
Where a 3PL fits in
A 3PL does not replace your compliance program, but it can help with the labeling work that happens after production.
- Inspecting inbound shipments for missing or wrong labels and reporting issues by style and variant
- Applying barcode labels, polybag stickers or retailer ticketing
- Holding or quarantining inventory that needs correction
- Supporting lot tracking for children's products so recalls can be managed
- Adding inserts such as care cards or warnings when required
The earlier problems are caught, the cheaper they are to fix.
A pre-production labeling checklist
A pre-production labeling checklist catches most problems before a single garment is sewn. Send it to your factory with every new style and confirm it against a physical sample before bulk production starts.
- Fiber content listed by generic name and percentage, including linings and trims where required
- Country of origin on the label and consistent with the product page
- Company name or RN number present and correct
- Care instructions tested against the full garment, including prints and embellishments
- Size label matching your size naming and storefront variant
- UPC or barcode on the hangtag or polybag matching the correct size and color
- Any children's tracking label, flammability or chemical warning that applies
Keep the approved sample and the checklist on file. If a later production run arrives with different labels, you have a reference to compare against and a clear record of what the factory agreed to. That record also helps when you answer a retailer's compliance questionnaire or a marketplace document request.
Frequently asked questions
What labels are required on clothing sold in the U.S.?
Most clothing sold in the U.S. needs fiber content, country of origin, the manufacturer's or responsible company's identity and a permanent care label, under FTC rules.
Do I need an RN number for my clothing brand?
An RN number is not required, but many brands use one because the FTC-issued number can identify the responsible company on labels instead of its full name.
Can a 3PL fix labeling problems on my apparel?
A 3PL can often catch labeling issues at receiving and apply barcodes, stickers, tickets or inserts, but sewn-in label errors may require factory or specialist rework.
