The Health Product Declaration provides a full disclosure of the potential chemicals of concern in products by comparing product ingredients to a set of priority “hazard” lists based on the GreenScreen for Safer Chemicals and additional lists from other government agencies.
Caesarstone has recently updated its HPD to align with the new HPD v2.1 standard, and created 2 HPDs:
The Health Product Declaration® for Caesarstone quartz surfaces for models that do not include recycled material
The Health Product Declaration® for Caesarstone quartz surfaces for models that include recycled material (glass/mirror)
Each declaration contains the precise list of models it covers.
