What is Oeko-Tex Standard 100?
Oeko-Tex Standard 100 is one of the world's best-known labels for textiles tested for harmful substances. It certifies that every component of a textile product—from the thread to the buttons, from the fabric to the prints—has been tested for over 100 harmful substances and found safe for human use. For silk fabric suppliers on Alibaba.com, this certification signals to buyers that your products meet international safety standards.
Four Product Classes Explained
Oeko-Tex Standard 100 divides certified products into four classes based on intended use and skin contact level. Understanding these classes helps you communicate product positioning clearly to B2B buyers:
Oeko-Tex Standard 100 Product Classes
| Class | Product Type | Testing Strictness | Best For |
|---|
| Class I | Baby products (0-3 years) | Most stringent | Infant clothing, baby bedding, silk swaddles |
| Class II | Direct skin contact | Very strict | Underwear, shirts, pajamas, silk pillowcases |
| Class III | No direct skin contact | Strict | Jackets, coats, lining fabrics |
| Class IV | Home textiles & decoration | Standard | Curtains, tablecloths, upholstery, sofa fabrics |
Class I has the strictest limits because babies have more sensitive skin. Most silk fabrics for apparel fall under Class II.
2026 Regulatory Updates: What Changed
Oeko-Tex announced new regulations effective June 1, 2026, with a 3-month transition period. The updates include revised testing standards, updated limit values for certain substances, and enhanced label requirements. For silk suppliers, this means certifications obtained before June 2026 may need renewal or verification to ensure continued compliance. Buyers sourcing for EU and North American markets are particularly attentive to these updates.
Certification Process Overview
Obtaining Oeko-Tex Standard 100 certification involves a structured process: application submission, document verification, laboratory testing of product samples, on-site audit (if required), and certificate issuance. Certificates are valid for one year and must be renewed annually. The certification is recognized globally and aligns with major regulations including REACH (EU), CPSIA (USA), and ECHA requirements. Over 35,000 companies worldwide hold Oeko-Tex certifications, making it a widely recognized trust signal for B2B buyers on Alibaba.com.
