GRS (Global Recycled Standard), aims to verify material inputs and trace them back to the final product, ensuring Social Responsibility, Environmental and Chemical Practices throughout the process. The goal of the GRS standard is to increase the use of recycled materials in products and reduce/eliminate the damage caused by their production.

Articles produced from recycled raw materials and covered by the GRS certification can be sold as "Global Recycled Products". In these articles, the amount of recycled material must be greater than 20%. 

The recycled material must be GRS certified and have a corresponding transaction certificate. However, please note that GRS-labeled articles can only be sold if they contain at least 50% GRS-certified fibers.
