Cal. Food and Agricultural Code § 67101

(a) The commission shall, not later than November 1 of each year, establish the assessment as a fixed rate or percentage of value for the following marketing season beginning November 1, and ending October 31. The assessment shall not exceed 612 percent of the gross dollar value of the year’s sales of avocados by all producers to handlers, or which are sold by handlers on behalf of producers. Expenditures for administrative purposes within the maximum assessment shall not exceed 212 percent of the gross dollar value of sales of avocados by all producers to handlers, or which are sold by handlers on behalf of producers. Assessments provided for in this section shall be upon the producer. The handler shall deduct that assessment from either amounts paid to the producer or amounts retained by the handler if the handler is also the producer, and the handler shall be a trustee of those funds until they are paid to the commission at the time and in the manner prescribed by the commission. (b) The combined assessment of the commission and any state marketing order shall not exceed 612 percent of the gross value of the year’s sales of avocados by all producers to handlers, or which are sold by handlers on behalf of producers.
