The National List is the definitive source for allowed materials. However, several agencies and organizations create comprehensive lists of brand name products and ingredients that may be used in organic processing. Among them are the Organic Materials Review Institute (OMRI) and the Washington State Department of Agriculture. All materials must be approved by CCOF before use.
Section 205.605 of the National List lists the non-agricultural items that can be used in organic products. Some items listed on the National List appear with restrictions or “annotations” that must be followed. Non-organic ingredients and processing aids used in organic products must be produced or handled without the use of genetically engineered organisms, irradiation, or sewage sludge and must not contain prohibited materials. Furthermore section 205.606 of the National List lists the agricultural items that can be used in an “organic” labeled product when deemed not commercially available in an organic form.
