Our certifications and memberships

Going beyond certifications 
On our journey to source our cotton in the most responsible way possible, we go beyond GOTS Certification, to provide our customers with consistently high-quality organic cotton. 


At Stanley/Stella, we have always used organic cotton but we know that even if our products are GOTS certified and GMOs are excluded from organic systems, organic isn't a claim of absolute freedom from contamination or GMOs' presence in our products.

This is why we take additional steps to reinforce traceability across our entire value chain. By limiting the number of suppliers, building relationships with farmers and ginners, and being one of the only companies to carry out our own random testing, we strive to live up to the commitments we make to our customers and to ourselves. 


The Global Organic Textile Standard (GOTS) is the leading worldwide standard for organic cotton. Based on both ecological and social criteria, it guarantees that cotton is organically grown without the use of genetically modified seeds or hazardous chemicals.

It also ensures traceability from post-harvesting of the raw material to the final customer, including transaction certificates at every stage of production.


The Organic Content Standard (OCS) is a voluntary international standard that verifies the presence and amount of organic material in a final product. It tracks the flow of the raw material from the source to the final product.

This standard applies to Stanley/Stella products that have less than 70% organic cotton.


The Global Recycled Standard (GRS) is the world’s leading standard for recycled textiles. The standard applies to the full supply chain and addresses traceability, environmental principles, social requirements, chemical content, and labelling. All  the  recycled  cotton  materials,  recycled  polyester,  and  recycled nylon we use is GRS certified.  


Standard 100 by OEKO-TEX ® is one of the world’s best-known standards for the assessment of harmful substances in fabrics. Our certification confirms that Stanley/Stella products contain no chemical substances that are harmful to human health and the environment, and guarantees that they comply with the EU REACH regulation. Standard 100 also prohibits certain potentially harmful substances even where these are not yet legally banned.


Stanley/Stella is ‘PETA-Approved’, which means that we do not conduct or commission any animal tests on ingredients, formulations, or finished products and pledge never to do so. Our products are made from 100% vegan materials and no ingredients of animal origin, ensuring that no harm is caused to animals.  


We are proud to approach the environmental and social challenges our industry faces in a constructive and collaborative way. Through our memberships of Fair Wear Foundation and Textile Exchange, we aim to reinforce the positive impact we can have across our operations.
