On May 13, 2010, the Humic Products Trade Association, Inc. (HPTA) filed articles of incorporation as a non-profit Wisconsin corporation.

Within four months of its inception, HPTA contracted EarthFax Engineering to help develop a standardized analysis for humic and fulvic acids based on the protocols supplied by the International Humic Substances Society (IHSS). Representatives were sent to the semi-annual meetings of the Association of American Plant Food Control Officials (AAPFCO) and the Association of American Feed Control Officials (AAFCO) for the purpose of changing the regulatory restrictions on the use of humic products.
