Manufacturing Process

Question: 

Do I need to know the manufacturing process for all of my ingredients?

Generally, if an ingredient is nonsynthetic, you will need to submit a manufacturing process that verifies the nonsynthetic nature of the ingredient. You do not need to submit the manufacturing process for any permitted synthetic ingredients or any currently OMRI Listed® products. If you are required to submit a manufacturing process and cannot get this information from the manufacturer, OMRI and the manufacturing company may enter into a third party agreement where the manufacturer may share that information directly with OMRI to preserve confidentiality.

To find out whether a synthetic substance is permitted for your product, see the OMRI Generic Materials List or the National Organic Program Rule at §205.601,§205.603, or §205.605(b).
