Single/multi Ingredient Products
What is the difference between a single ingredient product and a multi-ingredient product?
Single ingredient products contain only one ingredient or feedstock. For example, if limestone was simply mined from the earth it would be considered single ingredient (non-added impurities would not count as a second ingredient in this instance). Water (or moisture) does not count as an ingredient while calculating the fee, but its percentage in the final product should be included on the Total Ingredient List. Products that consist of a single multi-ingredient product that is already OMRI Listed are also considered to be a single ingredient. This is different from a repack as it may contain water and/or be listed in a different use class.
A multi-ingredient product contains two or more ingredients or feedstocks (including ingredients that are OMRI Listed). These include products that consist of previously formulated multi-ingredient products that are not already OMRI Listed®. For example, a blended fertilizer with blood and bone meals that is not already OMRI Listed and is being packaged is a multi-ingredient product because the product contains two separate substances. Another example is if OMRI Listed Product A is mixed with OMRI Listed Product B.
Each ingredient should be expressed on the Total Ingredient List provided in your Application Kit. There are examples of both single and multi-ingredient Total Ingredient Lists when you log into the website and navigate to the Application Support Downloads page in the right hand Applicant Menu.
OMRI charges a product fee based on whether a product is single ingredient or multi-ingredient with the exception of water and OMRI Listed products. For a full explanation of fees, please see the Review Cost page.
