What Is OMRI?
OMRI is an international nonprofit organization that determines which crop fertilizer and soil amendment products are acceptable for use on certified organic crops under the USDA National Organic Program, the Canadian Organic Standards, and the Mexico Organic Products Law. OMRI is ISO 17605 accredited as a material review organization, meaning certifiers can accept the OMRI Listed seal anywhere in the world.
Currently, U.S. Borax offers four OMRI Listed products: Granubor®
, and Optibor®
TG. All U.S. Borax products, including our OMRI Listed products, come from a clean, reliable, and fully traceable boron source that is further refined to ensure quality.
