Certification Process

NSF has helped thousands of manufacturers obtain both local and international market access by evaluating products to the requirements of multiple product standards. We certify products to sustainable standards using a simple six-step process.

  1. Your company completes the application process and submits signed documents to NSF.
  2. With our guidance, your company submits documentation for an off-site document review.
  3. We conduct an off-site documentation review and provide feedback and data analysis prior to the on-site audit.
  4. We conduct an on-site audit of the manufacturing facility or facilities.
  5. Once all follow up is complete, we grant certification and list your certified products on the NSF website.
  6. We schedule annual surveillance audits and notify you of recertification.

Our experts can help you reduce overall costs and expedite your time to market by bundling services, which can reduce the number of contracted service providers and required facility audits.
