NOSB to Discuss 40 Sunset Substances in Tucson

The National Organic Standards Board (NOSB) will discuss the re-listing or removal of 40 substances on the National List of Allowed & Prohibited Substances (National List) at their meeting in Tucson, Arizona on April 25-27, 2018. 
Members of the public are encouraged to submit public comments via using docket number AMS-NOP-17-0057-0001 until April 4, 2018. Additionally, oral comments will be accepted in-person and through pre-meeting webinars.
NOSB reviews all substances on the National List every five years to determine their status in organic production. NOSB makes recommendations to remove substances from the National List using the criteria of the substance being harmful to human health or the environment, the substance no longer being necessary due to the availability of a non-synthetic alternative, or the substance’s use being inconsistent with organic farming and handling practices.
Members of the board will use their discussion and public comments to inform their votes on the substances in the fall.
