Recycled Content Materials Analyte List
Analytical testing of recycled content materials used in a product is required for Cradle to Cradle certification in most cases. This document contains a list of chemical substances (i.e., analytes) and maximum allowable concentrations for commonly recycled material types and is supplemental to the Recycled Content Materials Assessment Methodology for use in Version 4.0 product assessments.
This list is based on the Cradle to Cradle Certified Version 4.0 Restricted Substances List (RSL), which is updated annually in July based on changes to the cited regulations that occurred during the previous year. As such, the Recycled Content Materials Analyte List will also be updated annually in July to reflect changes to the RSL. Any additions or changes to the maximum allowable concentrations in the RSL will be reflected in this document, along with any needed reference updates or clarifications.
A one-year transition period will follow the effective date of each annual update to the Recycled Content Materials Analytes List:
- Version 4.0 product assessment summaries for new certifications and recertifications submitted to C2CPII from 1 July 2022 through 30 June 2023 must demonstrate compliance with the 2021 Analyte List or the 2022 Analyte List Update.
- Version 4.0 product assessment summaries for new certifications and recertifications submitted from 1 July 2023 through 30 June 2024 must demonstrate compliance with the 2022 Analyte List Update or the 2023 Analyte List Update (to be released in July 2023).
NOTE: Beginning 1 July 2022, the 2022 Analyte List update should be used in all new certification and recertification assessment projects to ensure the product is in compliance with the Analyte List, and to avoid the need for suppliers to retest after each Analyte List’s ‘sunset date’.
