Certification is a key indicator to ascertain whether a piece of clothing is made from organic cotton. Recognized certifications include GOTS, USDA Organic, or EU Organic, as well as other international certifications. While GOTS (Global Organic Textile Standard) encompasses the entire textile supply chain from raw material harvesting to the manufacturing of the final product, USDA Organic or EU Organic certifications specifically attest that the cultivation of cotton adheres strictly to 100% organic criteria: without genetically modified seeds, and free from herbicides, pesticides, and chemical fertilizers.
