All inputs used in certified organic production must be in compliance with the requirements of the National Organic Program, as required at CFR §205.105. Producers and handlers must provide a list of all inputs to PCO annually as part of their annual updates.
PCO’s Materials Resource Team is at your service to provide reliable, timely, and consistent organic materials guidance to ensure that your inputs are in compliance.
PCO publishes an Annual Approved Materials List, which is provided both electronically and in print to PCO members. An Add/Drop List is also provided once a year to keep the list current.
Our list of Approved Materials currently contains more than 2800 approved brand name products, as well as applicable restrictions and contact information for suppliers.
Besides performing our own review service, PCO also recognizes review decisions by:
Brand name products must be approved either by PCO, OMRI or WSDA before being used in your organic operation. PCO does not provide any guarantee or endorsement for materials included on these Brand Name Lists. Using a product without verified approved status may jeopardize certified organic status of your operation or product. If in doubt about a product, please do not rely on information provided by salespeople – contact PCO directly and we will gladly assist you.
