GRAS Notices

The inventory of GRAS notices provides information about GRAS notices filed since 1998, when FDA received its first GRAS notice. As of October 17, 2016, the GRAS final rule (81 FR 54960; August 17, 2016) requires a specific format for a GRAS notice. Prior to that date, FDA processed GRAS notices under the framework of the GRAS proposed rule (62 FR 18938; April 17, 1997). Notices received prior to the effective date of the GRAS final rule provide examples for potential notifiers for the types of information that may support a GRAS conclusion. In the inventory, notices follow the requirements for the format and content of a GRAS notice as of the effective date of the GRAS final rule.

The inventory notes what type of response letter the FDA sent in response to the notice. Notifiers often resubmit notices that FDA previously ceased to evaluate at the notifier’s request, and resubmitted notices commonly receive a letter indicating FDA has no questions, after addressing deficiencies. In the inventory, entries for notices that were later resubmitted link to the newer entry in the final column. Newer entries for notices that were resubmitted include a link to the previous submission below the substance name.

Some GRNs that FDA previously ceased to evaluate at the notifier’s request were later resubmitted as a food additive petition. For each of these cases, the GRN detail page links to the food additive petition.

After issuing a response letter, we may issue a subsequent letter as circumstances warrant. The issue dates of any subsequent letters are listed under the column, "Date of add’l correspondence.”

As of July 2025, FDA is posting notices in a Docket at www.regulations.gov. In these cases, the link for the notices will take you to the document posted at www.regulations.gov. We will update this information approximately monthly. More information about this inventory is available on the GRAS Notice Inventory Introduction page.
