There are several Agricultural Institutes that regulate the production of organic nutrients. OMRI (Organics Materials Review Institute) is probably the most respected. Loosely they define organic fertilizer as a plant or animal by product that does not contain chemical salts (eg Epsom salts). If the topic is of further interest to you I will refer you to the following link:
NOP Program Standards.
