Drinking Water Treatment Chemicals Certification

Regulatory requirements for drinking water treatment chemicals vary from country to country—and sometimes even at a local level within the same country. National standards, local approval schemes, and shifting expectations can make it challenging to know the requirements in each area.

NSF helps you cut through this complexity. Whether you’re selling in one market or many, we offer testing and certification services to meet drinking water regulations worldwide. Our global team, regional labs, and strong industry connections make it easier for you to get the approvals you need, no matter where you’re doing business.

We certify a wide range of drinking water treatment chemicals, including:

• Corrosion and scale inhibitors.
• Coagulants and flocculants.
• Disinfection and oxidation chemicals.
• pH adjustment, softening, precipitation, and sequestering chemicals.
• Well drilling aids.
• Speciality chemicals used in drinking water treatment.

NSF/ANSI/CAN 60 is the most widely accepted certification for drinking water treatment chemicals, and one of our core services. If you’re selling in the US or Canada, this certification is required.

We’ve built deep expertise in NSF/ANSI/CAN 60 and offer tools to help you get started, including our Readiness Tool that helps you assess preparedness for certification to the standard.
