Organic Materials Review Institute (OMRI)
The Organic Materials Review Institute (OMRI) is a national nonprofit organization that determines which input products are certified for use in organic production and processing. OMRI Listed—or approved—products may be used on operations that are certified organic under the USDA National Organic Program. Product reviews are conducted as a third-party review of products. This means that OMRI is a disinterested party that makes recommendations to the organic operator and certifier.
