OMRI Class


What is an OMRI Class?

Classes are part of the OMRI classification system that groups products with similar end use attributes.  This helps to determine which standards are applied when reviewing the product for organic use and assists buyers in finding appropriate products. Applicants complete a Product Report form (which is included in the Application Kit) specific to the Use Class you are applying for.

The OMRI Product Use Classes are:
Crop Fertilizers and Soil Amendments (CF)
Crop Pest, Weed, and Disease Control (CP)
Crop Management Tools and Production Aids (CT)
Livestock Feed Ingredients (LF)
