California Code, Food and Agricultural Code (Formerly Agricultural Code) - FAC § 6033.5

(a) Any assessment that is imposed on the producer pursuant to this article is a personal debt of the producer.

(b) Every handler or producer-handler is personally liable for the payment of the assessment. The failure of the handler or producer-handler to collect the assessment does not exempt the handler or producer-handler from liability, and does not relieve the producer from the obligation to pay the assessment.

(c) Any producer, handler, or producer-handler who fails to file a return or pay the assessment or otherwise comply with Section 6033 shall pay a penalty of 10 percent of the amount of the assessment determined to be due, and, in addition, shall pay 1.5 percent interest per month on the unpaid balance of the assessment and the penalty.
