ammonium perfluorooctanoate
CAS 3825-26-1
EPA lists this substance on the non-confidential Toxic Substances Control Act Chemical Substance Inventory as Octanoic acid, 2,2,3,3,4,4,5,5,6,6,7,7,8,8,8-pentadecafluoro-, ammonium salt (1:1).
This is a TSCA industrial chemistry record, not a food or flavor assessment. Presence on the TSCA Inventory says a substance is in US commerce. It says nothing about whether it may be used in food, and this substance is not FEMA GRAS. For flavor ingredients see the FEMA GRAS lookup.
Commercial activity status
Active
EPA designates this substance active in US commerce, so no Notice of Activity Form B is required before manufacturing. What active and inactive mean.
EPA regulatory flags
EPA marks this listing with 2 flags. Each one is shown with EPA's own definition and what it obliges.
Indicates a substance that is identified in a final Significant New Use Rule.
What it obliges: A significant new use notice at least 90 days before manufacture or processing for a designated new use, under 40 CFR 721.25(a). Distributing the substance can require a notice of its own, and exporting triggers TSCA section 12(b) notification.
What it does not establish: Establishes that a section of 40 CFR part 721 subpart E names the substance. Whether your use is a designated significant new use can only be settled by reading that section.
Indicates a substance that is identified in a proposed Significant New Use Rule.
What it obliges: No significant new use notice yet. Export notification under TSCA section 12(b) already applies, because 40 CFR 721.20 reaches substances named in a proposed rule as well as a final one.
What it does not establish: A proposed rule may change or may never be finalized. Read the proposal.

What this page does not establish
It reports what EPA publishes about CAS 3825-26-1 in the July 2026 release of the non-confidential Inventory. It does not report the contents of any order or rule that a flag points at, because EPA does not publish those on the Inventory, and it does not say whether a particular use of yours is permitted.
It is also not a food or flavor clearance. This substance carries no FEMA GRAS number.
