General Marking Policies

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.
