Winter/Spring 2026 – Materials Update

PCO re-reviews approved input materials every five years to ensure they continue to meet regulatory requirements. As part of this process, we verify that product formulations and supporting documentation remain compliant with the National Organic Program (NOP) standards. Occasionally, we find that a product formulation has changed or no longer meets the criteria under which it was previously approved. When this occurs, we update our review and notify certified operations that are using the affected material via email or US mail for postal clients. These Status Change Notifications are issued quarterly. If you receive one, please read it carefully and review it in full. The notice will outline any required actions. It is important to follow the instructions provided, as failure to take the required action may impact your certification status. If you have any questions about a notification or how it applies to your operation, please contact your Certification Specialist immediately.

PCO is currently finalizing preparations for the 2026 PCO Annual Approved Materials List. The updated list will be distributed to clients by or before mid-April.
