Product Category Rules
Product Category Rule Development
As an American National Standards Institute (ANSI) eligible programme operator, NSF can guide industries, trade organisations 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 programme operator, NSF can assist your company in developing PCRs across multiple product groups and industries. We can expertly guide your organisation through an ISO 14025-compliant process to develop a PCR for your product categories.
Participate on a PCR Committee or as a Public Commenter
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 provide one-time feedback to our PCR Committee during a 30-day public comment period.
