The OMRI Listed seal assures the suitability of products for certified organic production, handling, and processing under the following conditions.
The certification recognizes organic integrity through clear information and guidance about materials, so that producers know which products are appropriate for organic operations. For certified organic farmers, the product must be included in the operator’s approved organic system (farm) plan.
Product use must be in accordance with any restrictions described in the OMRI Products List©, the OMRI Canada Products List or the OMRI Mexico Products List under the product’s category.
The certification is developed by its parent organization, Organic Materials Review Institute (OMRI), a 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.
