Each year, CCOF sends each client an OSP Materials List of all specific processing aid and farm/livestock input materials in use by the client. Before using a new processing aid or farm/livestock input material (fertilizer, pest control, livestock medication), you must request approval from CCOF. Use of materials, even OMRI and WSDA listed materials, without prior approval may result in a Notice of Noncompliance. If a material does not appear on your OSP Materials List, do not use it!
