California Code, Food and Agricultural Code (Formerly Agricultural Code) - FAC § 67081

(a) The secretary shall establish a list of producers in each district. In establishing the lists, the secretary shall require that handlers in the state submit the names, mailing addresses, grove location, and handled volume of each producer from whom they purchased or handled avocados in the preceding marketing season. The request for information from handlers shall be in writing and shall be filed by the handlers within 60 days following receipt of the written request.

(b) Any producer of avocados whose name does not appear upon the secretary's list of producers may have his or her name established on the list by filing with the commission a signed statement, identifying himself or herself as a producer. Failure to be on the list does not exempt the producer from paying assessments under this chapter.
