The Organic Materials Review Institute (OMRI) is a private, nonprofit organization that determines whether or not a product qualifies as organic under the USDA’s National Organic Program (NOP). Goods that are found to comply are listed on the OMRI Brand Name Products List (BNPL). The list is used by certifiers, growers, manufacturers and suppliers to confirm that an item is approved for organic use according to USDA rules.
Remember: Items not assessed or listed by OMRI may still meet USDA organic rules. OMRI charges application, review and annual listing fees; it may be that the producer has decided against the expense of being reviewed or listed by OMRI.
