Abstract: The agricultural chemical shuttle tank quality control and repackaging process of the present invention provides for standardized inspection, cleaning, repairing, and certification of the tanks so as to deliver precision crop protection chemicals to customers. The tanks include an ID label or bar code with information about the life cycle of the tank. The information is updated at one or more stages of the process. The tanks are classified according to chemical contents, and restricted for use in a single herbicide/pesticide classification throughout the tank life. A specialized automated wash station cleans the inside and outside of tanks of chemical residue and satisfies government environmental regulations for waste wash water.
