Impartiality Statement

Our credibility is our most valued asset. NSF and its family of companies (NSF) is committed to act impartially in carrying out our certification, testing, inspection, registration, validation and verification activities.

NSF manages risks to impartiality by adhering to accreditation standards and regulatory requirements and policies; providing the necessary training to appropriate staff; and ensuring that our evidence-based processes are documented. Together these actions safeguard against inappropriate influence from interested parties.

Providing service to our customers that meets their expectations is our primary function. In all aspects of our services we act impartially and safeguard our mark as a representation of our credibility, in order to provide the true value of third-party services to our customers.
