Products intended for use as organic inputs may make statements on the products label that affirm that the product is in accord with the National Organics Program (NOP) (e.g., "suitable for organic farming", "acceptable for use in organic production", "meets National Organic Program requirements for organic production", or "meets USDA [US Department of Agriculture] standards for organic production) and may use the logos issued by recognized agencies such as OMRI (Organic Materials Research Institute), USDA, certifying agencies, state programs, or other recognized organic input listing services. Such statements about organic inputs are exempt from requirements pertaining to organic labeling under the fertilizer law.
