In today’s textile industry, sustainability has become a language of trust.
For brands and consumers alike, the logos printed on a label — GOTS, RCS, OEKO-TEX — aren’t just symbols; they’re promises. Yet many people still ask: what do these certifications really mean? At Çağdaş Socks, we work with all three, and we believe understanding their value helps everyone — from sourcing teams to end customers — make more responsible choices.
GOTS: From Field to Factory
The Global Organic Textile Standard (GOTS) is one of the most comprehensive certifications in the textile world. It covers every stage of the supply chain — from the organic farming of fibers to the ethical treatment of workers. To qualify, cotton or wool must be grown without harmful pesticides or synthetic fertilizers, and every process afterward — spinning, dyeing, knitting, finishing — must comply with strict environmental and social standards.
GOTS-certified products also ensure traceability. Every batch of yarn can be tracked back to its source, and every chemical used must meet ecological safety requirements. In short, GOTS doesn’t just prove that your product is “organic”; it proves that your production is responsible from seed to shelf.
RCS: Closing the Loop
While GOTS focuses on organic fibers, the Recycled Claim Standard (RCS) is all about circularity. It verifies the presence and amount of recycled materials in a product. Whether it’s polyester made from post-consumer plastic bottles or recycled cotton blended into a new yarn, RCS ensures those materials are genuinely recovered and reused — not just claimed as “eco” for marketing.
For brands, this certification adds measurable proof of recycled content. For manufacturers like us, it pushes innovation: developing efficient recycling processes, reducing waste, and creating socks that combine sustainability with performance. In a world where consumers are more aware than ever, RCS provides the data to back up every sustainability statement.
OEKO-TEX® Standard 100: Safety You Can Feel
The OEKO-TEX® Standard 100 certification takes a different but equally vital approach — product safety. It guarantees that no harmful substances are present in textiles at any stage of production. Every thread, dye, and elastic component is tested against a list of over 1,000 restricted chemicals, ensuring that what touches your skin is safe and gentle.
For us, this certification represents everyday trust. Customers may not think about chemical residues or dye safety when they put on their socks — and that’s exactly the point. OEKO-TEX ensures they never have to.
Working Together for a Responsible Future
Each of these certifications focuses on a different aspect of sustainability:
GOTS ensures organic integrity, RCS promotes material circularity, and OEKO-TEX guarantees safety and comfort. Together, they create a holistic foundation for modern, ethical manufacturing.
At Çağdaş Socks, these aren’t just checkboxes — they’re part of how we work every day. Our goal is to combine verified sustainability with design excellence and industrial precision. Because true responsibility isn’t about following trends; it’s about building trust, one certified sock at a time.
