Content Claim Standard and its implementation
US Textile Exchange has recently published the Content Claim Standard (CSS) jointly with the CCS Implementation Manual
The CCS is a chain of custody standard that provides companies with a tool to verify that one or more specific materials are in a final product. It requires that each organisation along the supply chain take sufficient steps to ensure that the integrity and identity of the input material is preserved. However it does not validate any claims about a product beyond the amount of a specific material that is in it. The standard does not limit which type of input material may be claimed and therefore has a broad application spectrum.
