Registered Water Treatment Products for the Food Industry

Show your products are trusted with NSF registration, the definitive assurance of water treatment chemicals safe for use in food processing.

The right water treatment chemicals can help improve performance, deliver efficiencies, reduce operating costs and improve service life in equipment such as boilers, steam lines or cooling towers. Products must also be safe to use, especially if they might come into contact with food.

Register your water treatment chemicals with NSF and let your customers know your chemicals can be used safely in food production facilities. Our registration program is a continuation of the USDA product approval and listing program, which is based on meeting regulatory requirements, including FDA 21 CFR, for appropriate use and ingredient and labeling review. The program covers these categories of water treatment chemicals:

  • G1 general products
  • G2 phosphate products
  • G3 silicate products
  • G4 chlorine products
  • G5 cooling and retort water products
  • G6 boiler and steam line products — food contact
  • G7 boiler and steam line products — nonfood contact
  • GX ingredients for use in water treatment products

Find registered products — including water treatment chemicals independently validated as suitable for use in food facilities — in the NSF White BookTM, our online directory of registered nonfood compounds and proprietary substances.

Registered products can display the NSF registration mark. This recognized mark of assurance is trusted globally by the food industry and food safety regulators and auditors.
