Water Treatment Chemistry
NSF Nonfood Compounds
Mid South Chemical offers NSF Registered Nonfood Compounds across boiler, cooling and closed-loop, cleaners, and heat-transfer — built for food-plant water-treatment programs. Also linked from our boiler water treatment hub.
These products are NSF Registered Nonfood Compounds (Category Codes G5, G6, G7, A1, A3, HT1). They are not NSF/ANSI/CAN 60 drinking-water treatment chemical listings. Verify current registrations in the NSF White Book (company N04886). For NSF/ANSI/CAN 60 potable and RO products, see our potable water and reverse osmosis pages.
Contact us to confirm program fit for your plant. Product code, application, and listings only — no dose guidance on this public page.
