US clothing label requirements: fiber content, care and origin

Importing apparel into the United States involves more than sourcing quality fabrics and stitching garments correctly. Brands must also comply with strict labeling regulations enforced by the Federal Trade Commission (FTC) and U.S. Customs and Border Protection (CBP). Understanding US clothing label requirements imported apparel rules is essential for any brand planning to sell garments legally in the American market, and it becomes even more important when working with an overseas or nearshore manufacturing partner.

At CI Aliada SAS, a full package apparel manufacturer based in Bogota, Colombia, we help emerging and established brands navigate these requirements as part of our production process. In this article, we break down the three core elements every clothing label must include: fiber content, care instructions, and country of origin.

Why US Clothing Label Requirements Matter for Imported Apparel

The US clothing label requirements imported apparel guidelines exist to protect consumers by giving them accurate information about what they are buying and how to care for it. Failure to comply can result in shipment delays at customs, fines, or products being pulled from retail shelves. For brands manufacturing overseas, this means labeling compliance must be planned before production begins, not added as an afterthought.

These regulations are primarily governed by two federal laws:

• The Textile Fiber Products Identification Act (TFPIA), which covers fiber content disclosure.
• The Care Labeling Rule, which mandates instructions for washing, drying, ironing, and dry cleaning.

Additionally, CBP requires country-of-origin marking under separate customs regulations, which we'll cover further below.

Fiber Content Requirements

One of the most detailed aspects of US clothing label requirements imported apparel compliance is fiber content disclosure. The label must list all fibers present in the garment in descending order of weight, using generic fiber names (such as cotton, polyester, or elastane) rather than trademarked or brand names.

Key Rules for Fiber Content Labels

• Fibers making up 5% or more of the garment must be named individually with their exact percentage.
• Fibers under 5% can be listed as "other fiber" unless they provide a specific function, like elastane for stretch.
• If a garment has multiple components (like a lining or trim), each part with a distinct fiber content should be labeled separately.
• Percentages must add up to 100% and be reasonably accurate based on manufacturing testing.

When working with a maquila in Colombia experienced in international compliance, brands benefit from production teams that already understand how to document fiber blends accurately during manufacturing, reducing the risk of mislabeling.

Care Instructions on Clothing Labels

The Care Labeling Rule requires that every garment include reasonable instructions for its regular care. This helps consumers avoid damaging the product and reduces return and complaint rates for brands.

What Care Labels Must Include

• At least one method of care that is safe for the garment (washing or dry cleaning).
• Warnings if a common care method would harm the product, such as "Do not bleach" or "Do not tumble dry."
• Water temperature guidance when washing is recommended.
• Ironing instructions if applicable, including temperature limits.

Many international brands use standardized care symbols recognized globally, but for the US market, written instructions in English are required, even if symbols are also included. Manufacturers offering full package production, like CI Aliada SAS, typically integrate care label sourcing and printing directly into the production timeline, ensuring labels match the fabric composition and finishing techniques used for each specific garment.

Country of Origin Labeling

Country of origin marking is a separate but equally critical requirement under US clothing label requirements imported apparel regulations, enforced by CBP rather than the FTC. Every imported garment must clearly indicate where it was manufactured.

Common Country of Origin Rules

• The label must state "Made in [Country]" in a conspicuous, legible location.
• For garments assembled from components made in different countries, origin is generally determined by where the last substantial transformation occurred, typically cutting and sewing.
• The country of origin label must be permanently attached and not easily removable.
• It can often be combined with the fiber content and care label on a single tag, as long as all information remains legible.

This is one of the reasons more American brands are choosing nearshore manufacturing in Colombia over farther origins in Asia. Shorter shipping times, easier communication, and simplified compliance documentation make working with a maquila in Colombia an attractive option for brands that want faster turnaround and clearer origin traceability.

Label Placement and Durability Standards

Beyond content accuracy, labels must also meet placement and durability standards. They should be:

• Sewn into a location where they are easily found, such as the inside back neck for tops or the inside waistband for bottoms.
• Legible for the reasonable lifetime of the garment, resisting fading or peeling from washing.
• Free of misleading claims about performance, sustainability, or origin unless properly substantiated.

Poorly attached or low-quality labels are a common cause of customer complaints and returns, which is why label sourcing and application should be treated as a technical part of the production process rather than a minor detail.
