A marketing order may contain provisions for limiting the total quantity of any commodity, or of any grade, size, or quality of it, which may be marketed by producers, or processed, distributed, or otherwise handled within this state during any specified period by any and all persons that are engaged in such producer marketing, processing, distributing, or handling. Any such limitation shall be applied under a uniform rule which is applicable to all such persons so regulated. The total quantity of any such commodity which is so regulated and permitted to be marketed by producers, processed, distributed, or otherwise handled, shall not be less than the quantity which the director finds is reasonably necessary to supply the market demands of consumers of such commodity.

The marketing of green ripe olives is not, however, subject to any provisions of a marketing order which limits the total quantity of such commodity which may be marketed.
