Are You Certified by NSF or to NSF?
November 21, 2025
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:
- Authorised use of the NSF mark, recognised worldwide.
- Access to NSF Connect, our industry-leading project tracking portal.
- Dedicated project manager for personalised 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.
