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 certifiers "mark" on their packaging to help consumers and other buyers make educated purchasing decisions.
Recognized by regulatory agencies at the local, state, federal and international level, the NSF Certification Mark means that the product complies with all standard requirements. NSF conducts periodic unannounced inspections and product testing to verify that the product continues to comply with the standard. A complete list of products that have been certified by NSF can be found at www.nsf.org (click search listings in top-right corner)
