In the February 23, 2016, Federal Register, USDA's AMS National Organic Program announced the need for renewal of five synthetic substances (malic acid, microorganisms, activated charcoal, peracetic acid/peroxyacetic acid, and sodium acid pyrophosphate) and two nonsynthetic substances (ferric phosphate and hydrogen chloride) on the USDA National List of Allowed and Prohibited Substances ("National List"), along with any restrictive annotations. This National List identifies the synthetic substances that may be used and the nonsynthetic (natural) substances that may not be used in organic production. The National List also identifies synthetic, nonsynthetic nonagricultural, and nonorganic agricultural substances that may be used in organic handling. This document completes the 2016 National List Sunset Process. Document is effective September 12, 2016.
