Product Category Rules

As an American National Standards Institute (ANSI) eligible program operator, NSF can guide industries, trade organizations or individual companies through an ISO 14025-compliant process to develop a product category rule (PCR) for their product categories. We are a global leader in the development of PCRs and have extensive experience working with industries and stakeholders. We use an open consultative process to develop PCRs with participation from expert stakeholders in product manufacturing, supply chain management, regulatory, environmental consulting, life cycle assessment and other interested parties.

As a program operator, NSF can assist your company in developing PCRs across multiple product groups and industries. We can expertly guide your organization through an ISO 14025-compliant process to develop a PCR for your product categories.

Are you interested in being a part of the PCR development and revision process? You can participate as a voter or an observer on our PCR Committee, or providing one-time feedback to our PCR Committee during a 30-day public comment period.
