OCS Blended – Organic Content Standard
The Organic Content Standard (OCS) is a global standard for non-food products, including those made from organic cotton, with a minimum organic content of 5%, and a maximum of 95%. It provides transparent confirmation of content by tracking materials from source to final product. For businesses in the supply chain, it substantiates sustainability claims. Control Union provides certification to this standard, guiding organisations through the process.

What is OCS?
The OCS serves as a vital business-to-business tool, enabling companies to ensure they receive the quality they pay for and to substantiate claims for products such as organic textiles. It allows for transparent and comprehensive independent assessment of organic material content claims. As a leading certification body for the OCS scheme, Control Union has certified the majority of facilities, from ginning and spinning to dyeing and stitching, offering unparalleled expertise throughout the supply chain.
