Are You Certified by NSF or to NSF?

Not all certifications are created equal. Here’s what sets NSF certification apart:

Certified by NSF

Your product is certified by NSF, one of the most trusted independent certification bodies. Benefits include:

  • Authorized use of the NSF mark, recognized worldwide.
  • Access to NSF Connect, our industry-leading project tracking portal.
  • Dedicated project manager for personalized support.
  • Testing in NSF-owned laboratories by expert technicians.
  • Broad international acceptance of your product.

Certified to NSF standards

Your product was certified to an NSF/ANSI standard by another certification body.

  • Limited international acceptance.
  • No access to NSF Connect, dedicated support or NSF mark.
  • No assurance of NSF’s rigorous testing and auditing process.

The NSF mark matters. It’s more than compliance—it’s a symbol of trust, safety and global recognition.
