New NSF Home Product Certification Protocol Evaluates the Safety and Quality of Cookware Used in the Home

ANN ARBOR, Mich. — NSF International, an independent global organization that writes standards and protocols, tests and certifies products for the consumer goods, food and water industries, has certified Costco’s Kirkland Signature Brand cookware products to a new NSF protocol developed to evaluate the safety and quality of home cookware. Costco’s Kirkland Signature Brand Roasting Pan with Rack, 15-Piece Hard Anodized Aluminum Cookware Set, and 5-Qt. Covered Chef’s Casserole Dish are the first to earn certification to NSF Protocol P390: Stovetop Cookware for Home Use, developed as part of the new NSF Home Product Certification Program™.

The NSF Home Product Certification Program is based on, but separate from, the NSF commercial foodservice equipment certification program. Many state, county and city food codes in the U.S. mandate that commercial establishments use foodservice equipment that is certified to NSF commercial food equipment standards. The NSF Home Product Certification Program builds on this commercial expertise by now helping to ensure the safety and quality of consumer products and appliances used in the home.

Through this program, products are thoroughly tested against a rigorous set of protocols at NSF’s laboratories. The protocols are specific to home use and incorporate all applicable product quality, performance and FDA food contact material requirements. This enables manufacturers to streamline various product specifications into one set of testing requirements, helping assure product safety, while also increasing a product’s speed to market and reducing overall testing costs. Production facilities are audited to verify that systems are in place to help assure finished products meet the requirements.

NSF regulatory and public health experts worked with retailers, manufacturers, industry associations and regulatory agencies to develop the new NSF home product certification protocol for cookware, NSF Protocol P390: Stovetop Cookware for Home Use. This protocol covers metal cookware, sauté pans, skillets, griddles, grill pans and non-stick cookware intended for stovetop applications.

The protocol includes a rigorous set of testing requirements, which evaluate:

  • Performance (e.g. cleanability, corrosion resistance and durability)
  • Material safety (e.g. does not leach harmful contaminants such as heavy metals, phthalates or others into food)
  • Packaging and labeling (e.g. distributor/manufacturing location, description, quantity, usage directions, warning labels, disclaimer statements, lot number/expiration date and label claims are accurate and follow regulations)
  • Conformance to all applicable U.S., Canadian and EU product regulations and retailer requirements

NSF Certified for Home Use MarkNSF International tested and certified Costco’s Kirkland Signature Brand cookware products to Protocol P390. For earning NSF certification, these products will be able to bear the NSF “Certified for Home Use” mark.

"Many consumers may not realize the food served in restaurants and cafeterias is prepared using NSF-certified commercial foodservice equipment, which is a requirement in most U.S. states. NSF has taken similar safety and quality principles as used to evaluate the safety of foodservice equipment and applied them to products we use in our home kitchens. The NSF Certified for Home Use mark on Costco’s Kirkland Signature cookware products provides added assurance to consumers that the products they use to cook their food are made with safe materials, won’t leach harmful contaminants into the food and perform as advertised,” said Jim Klauer, Vice President of Merchandising for Costco.

“In addition to communicating safety and quality to consumers, the NSF Certified for Home Use mark indicates compliance to food contact material regulations and product acceptability to retail buyers. Streamlining this process saves manufacturers time and costs associated with meeting multiple regulatory requirements while verifying product quality for both retailers and suppliers,” said Sarah Krol, General Manager of Consumer Products, NSF International.

The new NSF Home Product Certification Program is part of NSF’s Consumer Products Division, which also offers private label assurance and specification development. The NSF Private Label Assurance Program verifies that private label products meet retailers’ quality standards, are comparable to national brands and comply with consumer product regulations.

About NSF International: NSF International is a global independent organization that writes standards and protocols, tests and certifies products for the food, water and consumer goods industries to minimize adverse health effects and protect the environment ( Founded in 1944, NSF is committed to protecting human health and safety worldwide. NSF is a World Health Organization Collaborating Centre for Food and Water Safety and Indoor Environment.

NSF International developed the first standards for commercial foodservice equipment in 1944, beginning with sanitation standards for soda fountain and luncheonette equipment. Since then, NSF has developed more than 75 American National Standards for a wide range of consumer and commercial products. Today, commercial food equipment certified to NSF national standards is mandated in state, county and city food codes throughout the U.S.NSF also developed the American National Standards for all materials and products that treat or come in contact with drinking water, including water filters. In 1990, the U.S. EPA replaced its own drinking water product advisory program with these NSF standards. Today, most plumbing codes require that pipes and plumbing components in commercial and residential buildings be certified to NSF standards.

The NSF Consumer Products Division builds on NSF’s expertise in developing national standards and protocols, testing and certification to help ensure the safety and quality of consumer products and appliances used in and around the home. These include bottled water and beverages, nutritional/dietary supplements, private label goods, personal care products, home appliances, cookware, bakeware and small kitchen electrics. Additional NSF services include environmental/sustainable product claims verification, safety audits for the food and water industries, and management systems registrations delivered through NSF International Strategic Registrations (NSF-ISR).
