Finding Materials Approved for Use on Organic Farms & Processing Facilities

The National List is the final arbiter of what substances may be allowed in organic crop, livestock, or processing operations. The current version of the National List may be viewed on the website of the National Organic Program. However, there are several resources that growers, livestock producers and processors may use as guidance documents in determining if a product is approved for use in organic production.
