The USDA’s National Organic Program regulates the use of substances and materials for farming, handling, and processing. This publication discusses three basic steps to ensure that materials use is compliant with organic standards and certification. First, understand the regulations relevant to your operation. Next, create an Organic System Plan with your certifier. Finally, keep records of your purchase and use of all materials. Following these steps will help ensure compliant use of materials, and avoid any use of a prohibited material or incorrect use of a restricted material???which could necessitate an additional three-year transition process.
