Material Inputs
Materials allowed in organic production
PCO’s experienced Materials Team is at your service to provide reliable, timely, and consistent organic materials guidance to ensure that your inputs are in compliance with National Organic Program regulations.
Our Materials team reviews your material inputs for compliance with the requirements of the National Organic Program as part of our comprehensive certification service.
Each material used in your organic operation must be documented in your Organic System Plan and approved for use before you start using it. PCO accepts input materials approved for NOP by OMRI, WSDA and CDFA in accordance with their approved use and applicable restrictions. If you have a question on a specific material or to confirm if a product is allowed before use, please contact PCO. Your Certification Specialist can be a resource in addition to our Materials Specialists.Request a Material Review:
Have a new product that you would like to use as part of your organic system? You can easily submit a review, and we will notify you of the result as soon as we have a determination. The more information you can provide, the quicker we can usually complete the review.
How to find Allowed Materials:
PCO publishes an Annual Approved Materials List, which is provided to PCO members every year, both electronically and in print. To make sure your list is current, PCO also sends out quarterly Add/Drop Lists.
Our list of Approved Materials currently contains more than 4,000 approved brand name products, as well as applicable restrictions and contact information for suppliers. PCO does not provide any guarantee or endorsement for materials included on our lists.
