Upcoming Website Maintenance
The OMRI Website may be unavailable Tuesday, September 2, between 8:00 PM and 11:00 PM Pacific Time (11:00 PM - 1:00 AM Eastern Time) due to website maintenance. We apologize for the inconvenience, and thank you for your patience.
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.
