National List 2023-2024 Sunset Review Notice
The USDA today published a Federal Register notice announcing the outcome of the 2023 and 2024 Sunset Review of materials on the National List of Allowed and Prohibited Substances (National List).
This notice renews 76 substances based on recommendations from the National Organic Standards Board’s (NOSB) sunset review and identifies which substances on the National List will be renewed.
This rule renews one substance until 2027, 42 substances until 2028, and 33 substances until 2029.
See the
for a complete list of renewed substances.
A renewal means the substance keeps its status as being allowed or prohibited in organic production and/or handling.
The NOSB must review every substance on the National List every five years to confirm that it continues to meet all criteria required to remain on the list. This review is called “sunset review.”
