No person other than a registered producer may ship, move, or cause to be shipped or moved, beer, ale, porter, malt beverage, or wine from outside the State to a point in the State, and only in accordance with the provisions of this chapter. No brand may be registered by the producer unless the person registering the brand is either the American producer or the primary American source of supply in the United States of the brand as herein defined, and it is unlawful for a wholesaler in this State to order, purchase, or receive beer, ale, porter, malt beverage, or wine from a producer who is not the primary American source of supply for the brand ordered, purchased, or received. The term primary American source of supply means the manufacturer, distiller, vintner, brewer, producer, winery, or owner of vinous or spirituous beverages at the time they become a marketable product, or bottler, or the exclusive agent of these persons, who, if the product cannot be secured directly from the manufacturer by an American distributor, is the source closest to the manufacturer in the channel of commerce from whom the product can be secured by an American distributor, or who, if the product can be secured directly from the manufacturer by an American distributor, is the manufacturer. The provisions of this section do not apply to a person who produces beer, ale, porter, malt beverage, or wine solely in this State and who subsequently ships or sells this beer, ale, porter, malt beverage, or wine solely in this State.
