Organic Materials Review Institute
OMRI supports organic integrity by developing clear information and guidance about materials, so that producers know which products are appropriate for organic operations. OMRI is a 501(c)3 nonprofit organization that provides an independent review of products, such as fertilizers, pest controls, livestock health care products, and numerous other inputs that are intended for use in certified organic production and processing.
When companies apply, OMRI reviews their products against the organic standards. Acceptable products are OMRI Listed® and appear on theOMRI Products List© or OMRI Canada Products List©. OMRI also provides technical support and training for professionals in the organic industry.
OMRI lists input products such as fertilizers, pest controls, and livestock care products that are compliant with organic standards. Allowed products are “OMRI Listed®” and may display the OMRI seal. These “input” products are then used to produce organic food and fiber products such as carrots, granola bars, and cotton that are certified by an accredited certifying body.
OMRI verifies input products intended for use in organic production. By focusing exclusively on inputs, OMRI provides essential expertise to support the organic certification process.
On average 10-15% of the applications that OMRI receives do not make it through the process, either because the application is withdrawn by the applicant, or the product is determined to be prohibited.
