Before diving into applicability, let's clarify what each certification covers and why the distinction matters for your Alibaba.com product listings.
ISO 9001: Quality Management System - This is a process certification, not a product certification. It verifies that your factory has documented quality management procedures in place: consistent production workflows, defect tracking systems, corrective action processes, and customer complaint handling. ISO 9001 doesn't guarantee your product is safe or organic; it guarantees you have systems to maintain consistent quality. For B2B buyers on Alibaba.com, ISO 9001 signals that you're a professional, reliable supplier capable of handling large orders with consistent quality across batches.
RoHS (Restriction of Hazardous Substances) - This EU directive restricts 10 specific hazardous substances in electrical and electronic equipment: lead, mercury, cadmium, hexavalent chromium, PBB, PBDE, and four phthalates (DEHP, BBP, DBP, DIBP). RoHS applies to products that require electricity to function. Pure textiles do not require electricity, therefore RoHS does not apply. However, if you're producing smart wearable clothing with integrated electronics (LED dresses, heated jackets, fitness-tracking garments), the electronic components must comply with RoHS [1].
OEKO-TEX Standard 100 - This is the textile industry's benchmark for product safety. It tests finished textile products and all components (yarns, fabrics, buttons, zippers, threads, labels) for over 1,000 regulated and non-regulated harmful substances including formaldehyde, azo dyes, heavy metals, and phthalates. OEKO-TEX has 4 product classes based on end use: Class I (baby products 0-3 years, strictest), Class II (direct skin contact like underwear), Class III (no direct skin contact like jackets), and Class IV (decorative materials like curtains). Certification is valid for 1 year and requires annual re-testing [3].
GOTS (Global Organic Textile Standard) - This is the leading international standard for organic fibers, covering the entire textile supply chain from harvesting raw materials to environmentally and socially responsible manufacturing, labeling, and distribution. GOTS requires minimum 70% certified organic fibers for 'Made with Organic' label and 95% for full organic claim. Unlike OEKO-TEX which only tests the final product, GOTS includes comprehensive social criteria (fair wages, safe working conditions, no child labor) and environmental requirements (wastewater treatment, energy management) [4].
REACH (Registration, Evaluation, Authorisation and Restriction of Chemicals) - This is an EU regulation that applies to almost all products sold in the EU, including pure textiles. REACH manages 240+ Substances of Very High Concern (SVHC). Unlike OEKO-TEX which is voluntary, REACH compliance is mandatory for EU market access. Many suppliers obtain OEKO-TEX certification because it covers REACH requirements plus additional substances, making it a more comprehensive choice for B2B buyers [2].
