NSF Certified products (except ingredients, materials, or products specifically exempted by policy) must bear an NSF Mark. Certified products must bear a laminated "foil" mark with an identifying number and data plate or label with the company name and address, or the product must have a nameplate, data plate, or label bearing a legible, authorized facsimile of the mark and the product trade designation and the name and address of the manufacturer. If the only identification on a certified item is the number of the mark, contact NSF to determine the identity of the company certified for the product.
For additional information on how to the use the mark and high-resolution marks for download, please refer to the NSF Marks Download page.
