Understanding the OEKO-TEX® Rating System: A Guide for Fabric Buyers
If you’ve ever shopped for fabric or textile products, you may have come across the term OEKO-TEX® on labels or product descriptions. But what does it actually mean? And why should you care?
In this blog, I’ll break down the OEKO-TEX® rating system in simple terms, so you know what to look for when buying fabrics and textiles—whether for dressmaking, home décor, or any other sewing projects.
What is OEKO-TEX®?
OEKO-TEX® is an independent certification system that tests textiles for harmful substances. It was developed by the International Association for Research and Testing in the Field of Textile and Leather Ecology (a bit of a mouthful, I know!). Essentially, it ensures that fabrics and textile products are safe for human health and environmentally responsible.
When you see an OEKO-TEX® label, it means the item has been tested against a strict set of standards for chemicals that could be harmful to humans or the environment.
Why Does OEKO-TEX® Matter?
Many fabrics go through extensive chemical processing—from dyes and finishes to flame retardants and waterproof coatings. Some of these chemicals, like formaldehyde or heavy metals, can be irritating to the skin or even pose long-term health risks.
Choosing OEKO-TEX®-certified fabrics gives you peace of mind that:
• The fabric is free from harmful substances at levels that could affect your health.
• It meets global safety standards, even if it was produced in a different country.
• It’s gentler on the environment, since OEKO-TEX® also considers sustainable production methods.
The Different OEKO-TEX® Certifications
There isn’t just one OEKO-TEX® certification—there are several, each covering different aspects of textile safety and sustainability. Here are the main ones you’re likely to see when buying fabric:
1. STANDARD 100 by OEKO-TEX®
• The most common certification, especially for fabric sold in shops.
• Ensures that every component of a product (threads, buttons, coatings) has been tested for harmful substances.
• Fabrics with this certification are safe for direct skin contact, making them ideal for clothing, bedding, and baby products.
2. MADE IN GREEN by OEKO-TEX®
• Includes all the safety standards of STANDARD 100, but also guarantees that the item was produced sustainably and ethically.
• This means the factory producing the fabric follows environmentally friendly processes and fair working conditions.
3. LEATHER STANDARD by OEKO-TEX®
• Similar to STANDARD 100 but specifically for leather goods, ensuring no harmful chemicals are used in leather processing.
4. STeP by OEKO-TEX® (Sustainable Textile & Leather Production)
• A certification for factories rather than individual products. It ensures that a manufacturer is using environmentally friendly production methods and treating workers fairly.
What to Look for When Buying Fabric
Now that you understand OEKO-TEX®, how can you use this knowledge when shopping for fabric?
1. Check the Label or Product Description
• Look for the STANDARD 100 by OEKO-TEX® certification if you want fabric free from harmful substances.
• If sustainability matters to you, go for MADE IN GREEN by OEKO-TEX®.
2. Ask the Supplier
• Not all fabrics will have a visible label, but reputable fabric shops and brands should be able to tell you if their textiles are certified.
3. Look for a Certification Number
• Every OEKO-TEX® certification comes with a unique number. You can verify it on the official OEKO-TEX® website to ensure it’s genuine.
4. Consider Who Will Be Using the Fabric
• For babies, children, or anyone with sensitive skin, OEKO-TEX® certified fabrics are the safest choice.
Final Thoughts
OEKO-TEX® certification is a great way to ensure you’re buying safe, high-quality, and environmentally responsible textiles. While it’s not the only sustainability certification out there, it’s one of the most widely recognized and reliable.
Next time you shop for fabric—whether online or in-store—keep an eye out for OEKO-TEX® labels. It’s a small step that can make a big difference for your health and the planet!
Happy sewing!
