To qualify, each component must meet health and safety requirements specific to its function in foodservice equipment.
Why is it important? NSF 51 certification increases market access, ensures compliance with local health departments, and helps food equipment gain instant regulatory acceptance in North America and internationally.
NSF/ANSI 61 is required for any product that touches drinking water during treatment or distribution in North America. It sets contaminant limits and evaluates whether materials leach harmful substances into water.
This certification applies to:
With NSF/ANSI 61, your product demonstrates compliance with health-based standards in the U.S. and Canada, and may also meet international testing requirements.
