Notices, Policies, and Disclosures

Disclosure Under the California Transparency in Supply Chains Act of 2010

Our goal at Fertizona and Compton Ag Services, through the manufacture and sale of premium crop protection, crop nutrition and seed products, is to facilitate the growth and betterment of the communities that we serve, helping our customers to achieve the maximum potential from their operations. Fertilizer Company of Arizona, Inc., an Arizona corporation and Compton Ag Services, L.L.C., a California limited liability company, (collectively “Fertizona”) are dedicated in providing you with essential services and products ensuring that the crop nutrients and crop protection products that we sell are supplied in an ethical and responsible manner. With regard to specific requirements of the California Transparency in Supply Chain Act of 2010, our practices include:


We routinely assesses risk related to our supply chain based primarily upon supplier quality performance, type of transaction, the specific commodity purchased, security standards, the geographic location of the source and other relevant business and legal criteria. We follow the trade laws of the United States and applicable laws of countries in which we operate, including the restrictions on export or doing business with certain people, companies or countries. Other than routine evaluation of our suppliers, Fertizona has no formal process for verification of product supply chains to evaluate and address risks of human trafficking and slavery.


We do not engage in verification of product supply chains to evaluate and address risks of human trafficking and slavery. Fertizona does not independently audit any of its suppliers to evaluate supplier compliance with company standards against trafficking and slavery in supply chains. Nonetheless, suppliers of crop nutrients and crop protection products are subject to inspections, announced and unannounced, by government agencies and third parties to ensure compliance with applicable laws including standards governing the manufacture, sale, labeling, branding, packaging, shipment, importation and distribution of agrichemicals.


All of Fertizona’s crop nutrient or crop protection suppliers who sell products in California must certify their compliance with the terms of the California Transparency in Supply Chain Act of 2010.


In all business dealings, Fertizona’s employees are required to operate within the law and to obey all applicable federal, state, local, and international laws and regulations. As part of company philosophy, Fertizona prohibits contracting with suppliers who use forced labor, child labor, whose practices violate applicable standards for working hours and conditions, and other subjects related to human trafficking and slavery.


Fertizona regularly trains its employees in work standards which includes ethical behavior, company policies and procedures and legal requirements that establish the manner in which we conduct business. In 2015 we commenced training of employees who source product or contract with our suppliers on human trafficking and slavery.
