This American National Standard, ANSI/NSC 373 Sustainable Production of Natural Dimension Stone, has been developed as part of the ongoing efforts of a number of interested parties to document and improve the sustainability profile of natural dimension stone production. Stakeholders involved in developing the Standard included stone producers, fabricators, end users such as architects, state agencies responsible for environmentally preferable product procurement practices, academics, and other interested parties.

This Chain of Custody standard complements ANSI/NSF 373 – Sustainability Assessment for Natural Dimension Stone, by driving sustainability throughout the supply chain, ensuring that natural stone products that are sustainably produced, are also handled throughout the supply chain in a manner that ensures their sustainability. These requirements are intended to form the basis of conformity assessment programs, such as third-party certification or registration.
This Guidance for Conformance to ANSI/NSC 373 was developed by Ecoform, LLC for the Natural Stone Council as part of the ongoing efforts of a number of interested parties to document and improve the sustainability profile of natural dimension stone production.
