The Recycled Claim Standard (RCS) and Global Recycled Standard (GRS) set the criteria for third-party certification of recycled materials and chain of custody. The GRS includes a higher (50%) minimum recycled content percentage and additional social and environmental requirements related to processing and chemical use. Recycled material verification Materials are verified to meet the ISO definition of “recycled”. Both pre-consumer and post-consumer material is accepted. Responsible production GRS sites are required to meet strict social and environmental requirements. Chemicals with harmful potential aren’t allowed to be used on GRS products. Chain of custody Certification makes sure the identity of the recycled content is maintained from feedstock to final product. Credible certification A professional, third-party certification body audits each stage in the supply chain. Confident communication Products that meet all requirements may be labeled with the RCS or GRS logo. Stakeholder engagement The RCS and GRS are managed with the input of producers, suppliers, brands, and retailers from all parts of the globe.
