Cal. Food & Agric. Code § 12841

(a) A person shall not sell for use in this state any pesticide products that have been registered by the director for which the mill assessment established by this article, and the regulations adopted pursuant to it, is not paid at the times specified in Section 12843.
(b) Except as provided in subdivision (d), every person who sells for use in this state a pesticide product that has been registered by the director shall pay to the director the applicable assessment. Those sales expressly include all sales made electronically, telephonically, or by any other means that result in a pesticide product being shipped to or used in this state. There is a rebuttable presumption that pesticide products that are sold or distributed into or within this state by any person are sold or distributed for use in this state.
(c) Upon application of a registrant, the director shall determine whether a fertilizer or paper product is used as a carrier for a pesticide, and is sold in combination, and whether the mill assessment under this article shall be on the pesticide value only, when the product is designed, developed, and manufactured, and sold primarily for other than a pesticide use. If the director finds that the combination product has such a major component and is designed, developed, manufactured, and sold primarily for other than a pesticide use, the assessment provided by this article shall be paid on the equivalent percentage of the sales price of the active ingredients of the pesticide product. The director shall establish this percentage of the sales price. The percentage shall be the ratio of that portion of the sales price attributable to the pesticide portion to the total sales price of the combination product.
(d) Assessments provided for in this article for sales of registered pesticides that are sold for use in this state shall be paid by the person or entity that first sold the pesticide for use in this state.
(e) It has been and continues to be the intent of the Legislature that this division requires the department to register all pesticides before their sale for use in this state and, except as otherwise provided by law, requires the department to regulate and control the use of pesticides in accordance with this division. Except as provided in Section 12841.1, the department shall continue to collect the assessment as provided in this article at the same rate on all registered agricultural and registered nonagricultural pesticides.

2. (2) The regulations adopted pursuant to this section, or any amendment thereto, shall be adopted by the director in accordance with Chapter 3.5 (commencing with Section 11340) of Part 1 of Division 3 of Title 2 of the Government Code. However, the adoption, amendment, readoption, or repeal of these regulations shall be considered by the Office of Administrative Law as an emergency, and necessary for the immediate preservation of the public peace, health, safety, and general welfare. Notwithstanding any other law, the regulations shall remain in effect until amended by the director. The director shall make available to the public, upon the adoption of an emergency regulation establishing a new rate, the information on which the director has calculated, based, or determined the new rate.
(g) The revenue collected pursuant to this section shall be deposited into the Department of Pesticide Regulation Fund and distributed as follows:
