The Organic Foods Production Act (OFPA) of 1990 requires the USDA to develop national standards for organically produced agricultural products. This is to assure consumers that agricultural products marketed as organic meet consistent and uniform standards.
The Organic Materials Review Institute (OMRI) is a 501(c)(3) nonprofit organization that specializes in the review of these substances. OMRI’s services are directed to all aspects of the organic industry with a primary focus on the decision makers who deal with the compliance status of generic materials and other “brand” name products. With the OMRI Generic Materials List and OMRI Brand Name Product List., the OMRI Lists hopes to provide some guidance on the suitability of material inputs under the USDA National Organic Program standards.
OMRI conducts materials review according to the standards established with implementation of the USDA National Organic Program (NOP) in October of 2002. Materials that are allowed or prohibited by the NOP Rule’s National List are compiled in the OMRI Generic Materials List. These lists are in a cross-referenced format organized under crops, livestock, and processing. Policy determinations relating to material standards are made by the OMRI Board, which seeks guidance on scientific and technical issues from the OMRI Advisory Council, and makes these lists available.
Here are direct links to the OMRI Lists which are posted on line. They also sell a book of these products known as the OMRI Product List.
They also post lists bimonthly on line and these .pdf files are available for download here.
