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 Fertilizer or Soil Amendment (CF)
Crop Pest, Weed, or Disease Control (CP)
Crop Management Tool or Production Aid (CT)
Livestock Feed Ingredient (LF)
Livestock Health Care (LH)
Livestock External Parasiticide or Pesticide (LP)
Livestock Management Tool or Production Aid (LT)
Processing Agricultural Ingredient or Processing Aid (PA)
Processing Non-agricultural Ingredient or Processing Aid (PN)
Processing Pest Control (PP)
Processing Sanitizer or Cleaner (PS)
Processing Container and Packaging Material (PC)
