Certification Process

We can support you in your commitment to achieve gluten-free certification. Whether you produce items at the beginning, middle or the end of the supply chain, you can earn gluten-free certification in just five steps.

Step 1: Product Review — You provide details about your gluten-free operation or products to our technical review team to help us understand the scope of your operation, the procedures you follow and the products your company processes, labels, handles and/or trades. A dedicated certification project manager guides you through the process. Product review includes:

  • Full documentation review and desk audit
  • Gluten-Free compliance plan (GCP) review
  • Individual product profile (IPP) and labeling review

Step 2: Onsite Inspection — An experienced inspector conducts an on-site evaluation of your operation to verify the information on your application and assembled documentation to ensure consistent gluten-free production. Upon achieving certification, annual on-site inspections are required to maintain certification.

Step 3: Testing — During the onsite inspection, the inspector collects a random product sample that will be tested to ensure gluten-free integrity at 15 ppm or less. The inspector also verifies that raw ingredient testing has been performed, and confirms one or more of the following:

  • Allergen affidavits
  • Certificate of analysis
  • Raw ingredient sourcing from an NSF-certified gluten-free supplier

Step 4: Certification — Your operation is classified as compliant and deemed certified to the applicable standard upon successful completion of steps 1-3. You receive a numbered certificate and can use the NSF gluten-free mark on your certified gluten-free products and in your marketing materials.

Step 5: Ongoing Compliance — We ensure ongoing annual continuous compliance.
