What Is Third-Party Certification?

Third-party certification means that an independent organization has reviewed the manufacturing process of a product and has independently determined that the final product complies with specific standards for safety, quality or performance. This review typically includes comprehensive formulation/material reviews, testing and facility inspections. Most certified products bear the certifier’s mark on their packaging to help consumers and other buyers make educated purchasing decisions.

NSF Certification

Recognized by regulatory agencies at the local, state, federal and international level, NSF certification demonstrates that a product complies with all standard requirements. NSF conducts periodic facility audits and product testing to verify that the product continues to comply with the standard. See the complete NSF product listings.

NSF’s programs include testing and certifying drinking water treatment products and water filters, commercial food service equipment and a wide array of consumer products such as bottled water, nutritional supplements, private label goods, personal care items and home appliances (washers, dryers and dishwashers).

Why Do Companies Seek NSF Certification?

Independent, third-party testing and certification through NSF helps organizations:

  • Demonstrate compliance with national or international standards and regulations
  • Demonstrate independent validation and verification of their commitment to safety and quality
  • Increase credibility and acceptance with retailers, consumers and regulators
  • Benefit from enhanced product quality and safety
