Safety Standards & Certifications for Handmade Textiles & Clothing

Standard for the Flammability of Clothing Textiles

Federal flammability standard for all clothing textiles sold in the U.S. Classifies fabrics into three categories: Class 1 (normal flammability — acceptable), Class 2 (intermediate flammability — acceptable for some uses), and Class 3 (rapid and intense burning — banned). Most commercially available fabrics meet Class 1.

For handmade sellers: Any clothing you sell must meet this standard. The good news: most woven and knit fabrics from commercial suppliers already meet Class 1. The risk areas are very lightweight fabrics (some chiffons, voiles), heavily napped or brushed fabrics, and fabrics with raised surface fibers. If you source from a commercial fabric supplier, ask for their flammability classification.

• All clothing textiles must be Class 1 (normal flammability) or Class 2 (intermediate, with labeling)
• Class 3 (rapid and intense burning) fabrics are banned from clothing use
• Testing uses a 45-degree angle flame test on conditioned specimens
• Plain surface textiles with a burn time ≥ 3.5 seconds are Class 1
• Suppliers of commercial fabrics typically maintain test records and can provide classification on request

OEKO-TEX Standard 100 — Confidence in Textiles

Tests textiles for over 100 potentially harmful substances at levels stricter than most legal requirements. The standard is regularly updated to reflect new scientific findings and regulatory changes. Products are tested in their actual state of use (after washing, for example) to reflect real-world exposure.

For handmade sellers: You can source OEKO-TEX certified fabrics, yarns, and threads from many commercial suppliers. The OEKO-TEX label on your source material means it has been independently tested for harmful substances. This is especially valuable for baby products, underwear, and items with prolonged skin contact. You can communicate this sourcing choice to buyers without claiming certification for your finished product (unless you pursue that separately).

• Product Class I (baby articles, up to 3 years): strictest limits — tests for formaldehyde (<16 mg/kg), banned azo dyes, heavy metals, phthalates, and more
• Product Class II (direct skin contact): formaldehyde <75 mg/kg, plus full substance testing
• Product Class III (no direct skin contact): formaldehyde <300 mg/kg, plus substance testing
• Tests for pH value, color fastness to perspiration, saliva (for baby products), and water
• Certification label includes a unique tracking number verifiable through the OEKO-TEX website

Global Organic Textile Standard, Version 7.0

The world's leading processing standard for organic fibers. Goes beyond just the fiber source to cover the entire supply chain: spinning, weaving, dyeing, finishing, manufacturing. Includes both environmental criteria (wastewater, chemical use, energy) and social criteria (labor standards).

For handmade sellers: If you want to label your textile products as organic, GOTS certification provides credible, third-party verification. For handmade sellers, the most practical approach is often to source GOTS-certified fabrics and yarns, clearly labeling which materials carry the certification. Full facility certification requires your workspace to meet GOTS processing standards, which can be challenging for home studios but is feasible for small workshops.

• 'Organic' label requires minimum 95% certified organic fibers
• 'Made with [X]% organic materials' requires minimum 70% certified organic fibers
• All chemical inputs must be on the approved GOTS Positive List (no hazardous substances)
• Accessories (buttons, zippers, trims) may be up to 10% of total product weight and must meet specified criteria
• Annual on-site inspection of certified facilities
• Full chain of custody from fiber to finished product

Textile Fiber Products Identification Act — 16 CFR Part 303

Requires that textile products sold in the U.S. carry labels disclosing the generic names and percentages of all fibers present, the manufacturer's name or registered identification number, and the country of manufacture. Applies to most clothing, accessories, and household textiles.

For handmade sellers: If you sell textile products, your items need labels listing the fiber content (e.g., '100% Cotton' or '80% Merino Wool / 20% Nylon'), your business name or RN/WPL number, and country of origin. For handmade items produced in the U.S., you can label them 'Made in USA.' This is a labeling rule, not a safety standard, but non-compliance can result in FTC enforcement action.

• Fiber content must list all fibers by generic name and percentage by weight, in descending order
• Manufacturer's name or FTC-issued Registered Identification Number (RN) required
• Country of origin (where the product was manufactured or processed) must be disclosed
• Labels must be securely attached and remain legible for the useful life of the product
• Exemptions exist for some items: belts, suspenders, arm bands, and certain other accessories

Care Labeling of Textile Wearing Apparel — 16 CFR Part 423

Requires manufacturers and importers of textile clothing to attach care labels with instructions for regular care. Labels must warn against any care method that would harm the product or others being cleaned with it. The instructions must be based on reliable evidence (testing or knowledge of the fiber and construction).

For handmade sellers: Every garment you sell needs a care label with washing/drying/ironing instructions. You can use standard care symbols or written instructions. The instructions must be accurate — if your hand-dyed fabric bleeds in the wash, the label needs to say 'wash separately' or 'cold water only.' For handmade items, this is often a woven or printed label sewn into the garment.

• At least one safe method of care must be provided (washing, drying, ironing, bleaching, or dry cleaning as applicable)
• If any regular care method would damage the product, a warning must be included
• Instructions can use ASTM D5489 standard care symbols or written instructions (or both)
• Labels must be permanently attached and remain legible throughout the useful life of the garment
• Instructions must be based on reliable evidence that the method will not harm the product

I don't need fiber content labels if I sell online or at craft fairs

Reality: The Textile Fiber Products Identification Act applies to textile products regardless of where they are sold. Online listings must include the required fiber content information, and products shipped to buyers must have physical labels attached.

Natural fibers like cotton and wool are always safer than synthetic fibers

Reality: The safety of a textile depends on its processing, not just the base fiber. Conventionally grown cotton is one of the most pesticide-intensive crops, and processing can introduce formaldehyde, heavy metals, and other substances. A synthetic fiber that has been OEKO-TEX certified may be safer against skin than an uncertified natural fiber.

If I buy fabric from a store, it's already compliant and I don't need to worry

Reality: Commercially available fabric is likely to meet the general flammability standard, but as a seller, you are responsible for the compliance of your finished products. This means proper labeling (fiber content, care, origin), compliance with any category-specific rules (like children's sleepwear), and being able to demonstrate that your products meet applicable standards.

I can call my products 'organic' if I use organic cotton fabric

Reality: Using organic materials in your product doesn't automatically make your product 'organic' in a certified sense. If you want to claim GOTS certification for your finished product, your entire facility and process must be certified. What you can truthfully say is 'made with GOTS-certified organic cotton' and reference your fabric supplier's certification.
