Nat’l List: One-ingredient products on the NOP List of Allowed Substances.
WSDA: Listed by the Washington State Department of Agriculture’s Organic Certification division for use in organic agriculture in Washington State. MOFGA has indicated that they will accept products on this list for their certification program.
AYC: Ask your certifier. Has not been reviewed by a certifier, but the active ingredient is allowed.

We cannot be responsible for errors or changes; changes are posted to our website as we become aware of them. In order to be certain that a product is allowed, check with your certifier.
