Issuing bodies include state wildlife agencies, county parks and recreation departments, public works divisions, and special-purpose mosquito control programs. Solicitations typically require vendors to hold supplier registration in state procurement systems, provide Material Safety Data Sheets, maintain minimum business tenure and comparable contract history, and comply with F.O.B. Destination delivery terms with firm pricing for specified periods.
